Dining Tables Divided by a Border: The Effect of Socio-Political Scenarios on Local Ecological Knowledge of Romanians Living in Ukrainian and Romanian Bukovina

Local cuisine is an important reservoir of local ecological knowledge shaped by a variety of socio-cultural, economic, and ecological factors. The aim was to document and compare the current use of wild and semi-cultivated plant food taxa by Romanians living in Romania and Ukraine. These two groups share similar ecological conditions and historically belonged to the same province, but were divided in the 1940s by the creation of a state border. We conducted 60 semi-structured interviews with rural residents. The contemporary use of 46 taxa (plus 5 cultivated taxa with uncommon uses), belonging to 20 families, for food consumption were recorded. Romanians in Romanian Bukovina used 27 taxa belonging to 15 families, while in Ukraine they used 40 taxa belonging to 18 families. Jams, sarmale, homemade beer, and the homemade alcoholic drink “socată” are used more by Romanians in Southern Bukovina, while tea, soups, and birch sap are used more in Northern Bukovina. We discuss the strong influence of socio-political scenarios on the use of wild food plants. Cross-ethnic marriages, as well as markets and women’s networks, i.e., “neighbors do so”, may have had a great impact on changes in wild food use. In addition, rapid changes in lifestyle (open work market and social migration) are other explanations for the abandonment of wild edible plants.


Introduction
The way people prepare their food is an important expression of local culture that is also shaped by the surrounding environment and historical background [1]. Indeed, different cultures often develop different recipes and the use of different ingredients. The underlying ecological knowledge is in fact shaped by a number of factors including sociocultural aspects, like religion [2], language [3], politics including governance systems [4][5][6], and economic features [7]. Such knowledge is not static, but rather dynamic as it evolves over time according to changes in the abovementioned factors. For instance, a change in lifestyle (influenced by economic shifts) was found to change the perceptions and the use of wild food plants [8][9][10] by changing motivations such as the desire for quality food and the pleasure of gathering wild plants [11], and also as a consequence of the disappearance of an agrarian lifestyle [12]. Wild food plants play an essential role in traditional cuisines across Europe [13], not to mention their economic value, especially in marginal rural areas in countries undergoing economic and governance transition [14]. The study of wild food plants in multicultural contexts has only been partially researched among migrant communities (e.g., [15]) and among coexistent ethnic groups (e.g., [16]), use similar wild food plants as they share the same language and, since 2015, can fr move across the border. Yet, even with an "untrained eye" one can see that Roman living under the same environmental conditions, in the same historical province, bu opposite sides of the border, have different wild food plant uses. However, the que remains: to what extent do the living conditions of the country and the social intercon tions that exist there influence local cuisine and wild food use?

Study Areas
Bukovina province has long been inhabited by Ukrainians and Romanians. It i lieved that the name derives from the fact that the region was covered by natural b (Fagus sylvatica) forest: in Ukrainian "бyк"-buk means beech tree (the word has a man root) and "Bukovina" means the beech land [43].
A complex history under different governance systems, e.g., the Turkish Em Moldavian Kingdom, Austro-Hungarian Empire , Kingdom of Rom , and then division into Southern and Northern Bukovina between Rom and the Soviet Union, respectively, have influenced population structure and distin natural resource use [18]. Therefore, in the study region, the population predomina consisted of Hutsuls in the mountainous part of Bukovina [35] as well as Romanians Ukrainians (the latter inhabiting the lowlands of Northern Bukovina). The multicul population of Bukovina was formed under the Austro-Hungarian law freeing loca habitants from taxes for 30 years, which led to the growth of the population, from 80 t sand in 1800 to 850 thousand at the beginning of the 20th century, via migrants from o overpopulated regions of the Austro-Hungarian Empire, such as Ukrainians, Germ Polish people, Jewish people, Hungarians, Roma people, etc. [18,34]. Bukovina was c acterized by ethno-political stability, as there were no cross-ethnic conflicts [18]. The sion of Bukovina between Romania and the Soviet Union in 1940 led to changes in multicultural population structure, especially in Northern Bukovina. Soviet governor itiated depopulation and forcibly sent Romanians, Germans and Polish people away In Southern Bukovina, Jewish people were deported and Hungarians and Germ moved out [45]. Rich Ukrainians were sent to Siberia and, later, the Romanians stayed in Northern Bukovina (in the territory of the Soviet Union) did not have the portunity to migrate to Romania. There are historical data that many Romanians killed while trying to escape from the Soviet Union [44,45].
The study was conducted in a lowland area of Northern Bukovina, Ukraine and uplands of Southern Bukovina, Romania ( Figure 1).  After Romania joined the European Union (2007) the economic situation improved and crossing the border to purchase consumer goods became popular [46]. In 2015, the Romanian and Ukrainian governments signed an agreement on "small cross-border movement" [47]. This allows residents of Romania and Ukraine who permanently live in the 35-50 km border zone to cross the border without obtaining a visa. People have to apply for a card, which is issued once every two years, and then they can cross into the other country, but not outside the 35-50 km small movement zone. There is a list of villages on both sides that are included in this agreement, and our study villages appear on this list. This agreement allows Romanians living in Ukraine to freely travel to visit their relatives and vice versa [46]. This also includes economic benefits for both areas as residents now commute and buy cheaper or better groceries on both sides of the border. In June 2018, Ukraine signed an agreement with the European Union establishing no-visa entry for Ukrainian residents possessing biometric passports to member states of the Schengen area.
Our participatory observation in Northern Bukovina in 2018-2019 revealed a large number of cars with foreign plates (from Romania, Great Britain, Germany, and others). As was explained by locals, to officially register a car in Ukraine costs a lot of money, sometimes more than the price of the car, so locals use foreign license plates. This also helps to travel abroad, because for a Ukrainian registered car you need to buy insurance. Economic development in the area is seen in brand new houses built close to old ones with wooden roofs (see Figures 2 and 3). Even though it is still Northern Bukovina, the Hutsul area of Putyla [4] is much poorer with a worse infrastructure compared with the region of Storozenetskyi and Gluboka where Romanians and Ukrainians live.

Every household engaged in small-scale family farming, including both animal breeding (mainly cows, chickens, ducks, and goats, and rarely sheep) and vegetable gardens for home consumption (mainly corn, cabbage, potatoes, onions, garlic, beetroot, beans, and carrots, as well as many other crops).

Northern Bukovina, Ukraine and Southern Bukovina, Romania
Northern Bukovina corresponds to the southern-eastern part of Chernivci region (except Hotynchshyna). The landscape consists of agricultural fields and some beech forests ( Table 1). The Glybotskyi and Storozenetskyi region is situated in the foothills of the Carpathian Mountains and is located in the Prut-Sirets interfluve. The highest peak is 475 m a.s.l.
Romanians live in villages close to the Romanian border, in the regions of Glybozkij, Gerzaivskyi and Storozenetskyi, which are dominated by a rural population. Based on the last country census in 2001, there are 114,555 Romanians living in Chernivci Region (an increase from the 84,800 people in 1970). There are 76 Romanian schools (financed by the Ukrainian state) and 13 mixed schools that teach in both Ukrainian and Romanian. There are also 12 local newspapers in the Romanian language as well as three bilingual newspapers (Romanian and Ukrainian). In addition, there are 10 non-governmental Romanian national cultural organizations in Chernivci Region.
Romanians reside in the lowlands of Southern Bukovina, which nearly corresponds to present-day Suceava County with around 635,000 inhabitants (Table 1).
In the municipality of Straja, where we conducted the study, most of the approximately 5000 inhabitants are particularly devoted to mountain agriculture, organized in small-scale farming activities including both animal breeding and crop cultivation.

After joining the European Union, the government of Romania has welcomed the issuing of a Romanian passport if someone meets the required criteria (proof that you have a Romanian relative, know some of the Romanian language, etc.). Respondents from the Ukrainian side explained that with the help of that passport they can freely travel to other European countries for seasonal or permanent employment, where salaries are much higher.

Data Collection
Fieldwork was carried out in the summers of 2018 and 2019. This study is part of the broader research project "Ethnobotany of Divided Generations" which, using the same method for data collection, aims to compare ethnobotanical knowledge of groups divided by the creation of a border during or after the Soviet time. The sample comprised 30 people from each side of the border, chosen pseudo-randomly, sometimes using snowball and convenient sampling methods. People were approached in streets, gardens, and fields, as well as in public places like libraries, bus stops, and markets. Oral informed consent was obtained prior to each interview. The respondents were given full freedom to talk about the subject. Only people permanently living in the study area were interviewed. Sixty interviews were conducted mainly in Romanian, but also in Russian or Ukrainian, depending on the preference of the interviewee. Participatory observation was performed during the summer of 2018. Most of the interviews in both Southern and Northern Bukovina were conducted with the help of a field assistant and facilitator, native in Romanian (for Southern Bukovina) and in the local Romanian dialect (for Northern Bukovina), who asked the questions, listened to responses, and posed follow-up questions, as Romanian is not the native language of the authors. The face-to-face interviews lasted from 20 minutes to 2 h. This study is part of a larger research project, in which questions on the use of wild plants were grouped into food, medicine, ritual and other uses modules. The food module consisted of questions specifying the use of wild plants for tea, soups, salads, main dishes and desserts, as well as any information the interviewee wanted to share about wild taxa use for culinary purposes. Oral consent was obtained prior to each interview, in which the aim of the project and the anonymous status of the interviewee were explained, as well as the condition that they could stop and withdraw all data and information at any stage of the interview. We strictly followed the ethical guidelines prescribed by the International Society of Ethnobiology [52], and the study protocol was approved by the Ethical Committee of Ca' Foscari University of Venice.
During the interviews herbarium voucher specimens were collected. The Ukrainian voucher specimens are stored in the Nature Reserve "Roztochya" UAV with codes NB001-NB289 and the Romanian voucher specimens at Ca' Foscari University of Venice UVV bearing codes SB001-SB094. The mentioned taxa were collected and then identified according to the local flora [53]. Taxonomic identification, botanical nomenclature, and family assignments followed the Flora Europaea [54], The Plant List database [55], and Angiosperm Phylogeny Group IV [56].
Participatory observation at local markets, shops, restaurants and near houses was performed, focusing on the wild food plants and products made from various wild parts and fruits that are sold. Participatory observations at local markets (on specific days of the week, so-called "market days") and selling locations (e.g., on the side of the road) were carried out in order to identify supply and demand of wild products in both study areas. While conducting interviews, we also made observations of home gardens and the vegetables planted by households.

Data Analysis
The gathered data were organized as Detailed Use Reports (DUR), where each interviewee mentioned the use of a plant and mode of preparation (e.g., dried blueberries leaves used for tea or the leaves of horseradish as a seasoning for fermented foods) documented into the Excel spreadsheet. The spreadsheet includes informant code, language of the interview, Latin name, taxonomic family, local name (Ukrainian names were transliterated using the system adopted by the [57]; Russian names were transliterated following the general transcription rules, with the use of the webpage www.calc.ru, time of use (always, in the past, recently abandoned, recently adopted), food use, mode of preparation, source of knowledge, and comments. For all calculations only wild and semi-wild taxa were used, while unusual uses of cultivated taxa are reported only in Table 3 and the discussion.
Following the methodology of González-Tejero et al. [58], we calculated the Jaccard similarity index as: where A is the number of recorded species in study area 1, B is the number of species recorded in study area 2, and C is the number of species common to both study areas 1 and 2. An index value close to 100 indicates that the plant uses of the two groups are very similar, while a value close to 0 indicates that the groups are very different.
The respondents were selected using convenient sampling, in which they were approached in gardens and yards, during hay making, or at local markets. Only two people refused to speak with us, and so response rate was high; everyone else was friendly and willing to discuss wild food issues and their life experiences.
In Northern and Southern Bukovina 60 interviews were conducted (see Table 2). In the Ukrainian study areas, Romanian is the official language in schools, while students study the Ukrainian language some hours every week. In the regional (Oblast) government offices, Ukrainian is used as the primary language, while in local village councils Romanian is spoken. In the street, Romanian and local Romanian dialects are used. As there are Ukrainians living in those villages or married to Romanians, Ukrainian with a mixture of Romanized words is used.
Furthermore, we classified the used plants into two categories based on their level of wildness: wild plants-taxa that grow spontaneously in the surrounding environment without human intervention (e.g., Vaccinium myrtillus); semi-cultivated plants-taxa that grow without direct human intervention, but were once planted in gardens (e.g., Armoracia rusticana).
Additionally, we compared our results with the wild food plant uses collected by the authors using the same interview structure among Hutsuls in the mountainous area of Bukovina in Ukraine and Romania [6].
To process the data statistically, on the request of the academic editor, we first ran a boxplot to graphically check the data. We observed that use categories of Romanians living in Ukraine are more scattered than those of Romanians living in Romania. Therefore, in order to test the observed difference between the two groups we performed a Wilcoxon test on use categories reported by Romanians living in Ukraine and in Romania. We set α = 0.05. In addition, we verified significance with a Kruskal-Wallis test using the same significance level. Both analyses were conducted using R software R (version 3.6.1).

Factor of Informant Consensus
The Factor of informant consensus (FIC) was calculated as the number of use citations in each category (Nur) minus the number of species used (Nt), divided by the number of use citations in each category minus one [59].
The high values (near 1) indicate that the majority of respondents propose a low number of taxa for cooking in this food category, while low values (near 0) indicate the respondents' disagreement about taxa used for certain food categories.

Caveats of the Study
Before discussing the results of the study we want to mention some caveats which may affect our interpretation and were considered in the following discussion. As the research is qualitative, the statistical analysis showed the following results: we performed a Wilcoxon test and a Kruskal-Wallis test, and both analyses revealed that there is no significant difference between the use categories of the two groups of Romanians living across the border. Indeed, the p-value for the Wilcoxon test was 0.16 and 0.092 for the Kruskal-Wallis test. Assuming that the null hypothesis for both tests was the equivalence of distributions of two groups, and given that the p-values are higher than 0.05, we accept the null hypothesis. We conclude that the two groups of Romanians do not present a statistically significant difference in the use of plant categories. However, we consider that the present differences, even though statistically non-significant, are important from a cultural perspective and we further focus on qualitative methods that are better suited for the analysis of cultural phenomena.
Romanian interviewees in Romania reported 27 taxa belonging to 15 families, plus five cultivated taxa with uncommon uses, used for food. In Ukraine, Romanians named 40 taxa belonging to 18 families plus four cultivated taxa. Cultivated taxa, such as the wood of Prunus avium, P. cerasus, P. domestica, and Malus domestica, were used for smoking meat and Vitis vinifera leaves were used for making sarmale, which are uncommon uses, and thus we included them in the study.
In Northern Bukovina, interviewees reported 19 taxa not named by Romanians in Romania (see Table 3), with more than twice the number of uses. These taxa included Achillea millefolium, Crataegus spp., Hypericum spp., Matricaria chamomilla, Betula spp. (Betula pendula and Betula pubescens which locals use as "birch sap"), and Rumex acetosa.

These taxa included Achillea millefolium, Crataegus spp., Hypericum spp., Matricaria chamomilla, Betula spp. (Betula pendula and Betula pubescens which locals use as "birch sap"), and Rumex acetosa.
More than 70% of interviewees in both areas used Rubus idaeus ( Figure 5), while Fagus sylvatica and Urtica dioica were used on both sides of the border but with different intensity. Fagus sylvatica was used four times more often in Southern Bukovina, whereas Urtica dioica was used three times more often in Northern Bukovina.
The division of used plant parts in Southern Bukovina was the following: fruits (119 DUR), aerial parts (63 DUR) including leaves (29 DUR), flowers (22 DUR) and petals (13 DUR), roots (22 DUR), and wood (18 DUR). In Northern Bukovina the division of used plant parts was as follows: aerial parts (125 DUR) including leaves (47 DUR), fruits (110 DUR), flowers (16 DUR), roots (21 DUR), and wood (5 DUR). Comparison shows that the most commonly used plant parts were fruits by Romanians in Romania and aerial parts by Romanians in Ukraine.
Seventeen taxa in Southern Bukovina and 26 taxa in Northern Bukovina were used by at least 10% of interviewees, with 13 shared taxa. Figure 6 shows the most important differences between the two samples: teas, fermented preparations, and fresh snack consumption are quite prevalent among Romanians in Ukraine, while Romanians in Romania favor wild food plant-based jams, compotes, syrups, and sarmale, as well as smoking meat.

This picture largely corresponds to the national cuisines of the respective countries [60][61][62][63], which seem to have greatly influenced the two divergent trajectories of Romanians during the past century. The predominance of lacto-fermentations among Ukrainians is possibly linked to old Slavic customs, while the prevalence teas may have been introduced via the promotion of popular teas spread through popular literature in the former Soviet Union during the Communist era [64].
In Romania, sarmale, jams, compotes, and syrups represent quintessential elements of Romanian cuisine, which historically was greatly influenced by the Ottomans. The prevalent custom of smoking meat at home in Romanian Bukovina may be linked to the persistence of this custom, which has not been weakened by food industrialization, as may have happened in Ukraine during the administration of the USSR food system. The "deficit" (a word that corresponds to the lack of high-demand products in markets, e.g., meat or sugar, during Soviet times) of meat may have contributed to a decline in the custom of smoking it among Romanians in Ukrainian Bukovina.
In Northern Bukovina the most prevalent wild food preparation was tea, while in Southern Bukovina it was jam (see Figure 6). Winter preserves, both fermented and marinated, were also highlighted. Spring soups made with four wild taxa (including Urtica dioica and Rumex spp.) were mentioned as well.

Spring soups made with four wild taxa (including Urtica dioica and Rumex spp.) were mentioned as well. Birch sap as a beverage was only named by Romanians in Ukraine because it was considered medicinal by Romanians in Romania. Salads made with wild plants were named by ten interviewees on each side of the border.
In Southern Bukovina, the fruits of Rubus idaeus, Rubus spp., Vaccinium myrtillus, and Fragaria vesca, were used for jam, as were the flowers of Rosa rugosa, Rosa centifolia, and Taraxacum campylodes.
The leaves of Tussilago farfara, Atriplex hortensis, Rumex spp., Brassica oleracea, Vitis vinifera, and Armoracia rusticana are used for making sarmale (from the Romanian "sarmale"; this dish consists of ground meat with rice or corn rolled in different types of the leaves, e.g., cabbage or beetroot). Sarmale was a popular preparation use of wild taxa for food. Romanian interviewees in Ukraine called this dish "gălus , te", but they used fewer taxa, only the leaves of Tussilago farfara and Rumex spp.
For soups, Romanians in Romania used the young leaves of Urtica dioica and Atriplex hortensis in springtime. Romanians in Ukraine used more species for making soups, including Urtica dioica, Rumex acetosa, Rumex spp., and Thymus spp. as seasoning. Urtica dioica was named in both areas as an early spring food, used for making borshch (typically the term "borshch" is used to refer to a soup with meat, cabbage, carrots, potatoes, tomatoes, and beetroot with sour cream, which should be red in color). Another variety called "green borshch" is made with carrots, potatoes, boiled eggs, sour cream, and different green plants like Urtica dioica or Rumex acetosa, (thus the color of the soup is green). In Ukrainian Bukovina, Urtica dioica was used for stew with sour cream, in omelets and scrambled eggs, and for frying with eggs: "Nettle, in the spring, when it is young and small, we boil it and stir fry it and eat it" explained a Romanian woman born in 1939. Interviewees highlighted that they use nettle leaves only in early spring when they are tender. Fried young sprouts with sour cream were also mentioned as a "vitamin food" during spring time.
In both areas, Armoracia rusticana was the most popular fresh root that was used for salads with beetroot and as a seasoning for pickles and fermenting winter preserves ( Figure 7). Romanians in Northern Bukovina used the young leaves of Urtica dioica, Plantago major, and Taraxacum campylodes for salads, whereas Southern Bukovinians only used Armoracia rusticana. It was referred to as semi-cultivated because it grows everywhere, including home gardens.

Plant-Based Beverages
Alcoholic beverages were only mentioned in Southern Bukovina. This included rachiu, which is prepared with Carum carvi and home-distilled alcohol (see Figure 7). Aromatized alcohol drinks were also popular. The fruits of Rubus idaeus and Vaccinium vitisidaea macerated in alcohol were mentioned by Romanians in Romania. In addition, the fruits of Vaccinium myrtillus were used for an alcoholic drink called "afinătă" (from the Romanian afină-blueberry), which added colored and aroma to the alcohol. Four interviewees also mentioned homemade beer, which was made from the flowers of Humulus lupulus or sometimes the flowers of Sambucus nigra.
Syrups made from Rubus idaeus, Fragaria vesca, Rosa rugosa or Rosa centifolia, and Rubus fructicosus were mentioned by Romanians in Southern Bukovina. Their use was intended for weekly fasting days: "Usually when you fast on Wednesdays and Fridays you eat raspberry syrup with bread", explained a man born in 1965. In both study areas, Romanians fasted on Wednesdays and Fridays and during four fasting periods throughout The dominant use of wild food for salads was that of grated roots of Armoracia rusticana, which was named by 47% of Romanians in Romania.

Wild and Cultivated Plants for Smoking
Fagus sylvatica was used in both areas for smoking meat. The wood of Prunus avium (9 DUR), Malus domestica (2 DUR), Prunus cerasus (4 DUR), and Prunus domestica (8 DUR) was also used for smoking meat by Romanians in Romania. Meat smoking was explained as a way "for meat to last long", because when you raise your own pigs, you have to be able to store the meat. In earlier times, when freezers were not available, smoking was an important preservation practice for local livelihoods.
In Northern Bukovina, besides Fagus sylvatica, the wood of Carpinus betulus was used for smoking meat. In addition, in both areas of Bukovina, fruit trees branches were mentioned as "adding taste and color", which was explained as: when you prune trees in your garden in the autumn and spring, you keep the branches for smoking purposes. As in Southern Bukovina, the wood of Prunus avium (5 DUR), Malus domestica (1 DUR), Prunus cerasus (4 DUR), and Prunus domestica (4 DUR) was also used for smoking meat in Northern Bukovina. The wood of cherry trees gives a reddish color to the meat, and the more cherry wood you burn, the deeper the color of red you achieve, explained a retired interviewee. Smoking was mentioned as an important practice for the long preservation of pork meat. In Southern Bukovina, only one interviewee mentioned the practice of cheese smoking. Smoking practices and the use of both wild and cultivated taxa were not mentioned by researchers either in Romania [4,33] or Ukraine [7,24]. Historical sources show that this practice of preserving meat was popular among inhabitants of the Carpathian Mountains [34,43].

Plant-Based Beverages
Alcoholic beverages were only mentioned in Southern Bukovina. This included rachiu, which is prepared with Carum carvi and home-distilled alcohol (see Figure 7). Aromatized alcohol drinks were also popular. The fruits of Rubus idaeus and Vaccinium vitis-idaea macerated in alcohol were mentioned by Romanians in Romania. In addition, the fruits of Vaccinium myrtillus were used for an alcoholic drink called "afinătă" (from the Romanian afină-blueberry), which added colored and aroma to the alcohol. Four interviewees also mentioned homemade beer, which was made from the flowers of Humulus lupulus or sometimes the flowers of Sambucus nigra.
Syrups made from Rubus idaeus, Fragaria vesca, Rosa rugosa or Rosa centifolia, and Rubus fructicosus were mentioned by Romanians in Southern Bukovina. Their use was intended for weekly fasting days: "Usually when you fast on Wednesdays and Fridays you eat raspberry syrup with bread", explained a man born in 1965. In both study areas, Romanians fasted on Wednesdays and Fridays and during four fasting periods throughout the year. Meat and dairy products are not allowed to be eaten on those days, and thus syrups and jams made from wild fruits are consumed by locals. The use of food plants for fasting, rituals and ceremonies needs to be more thoroughly studied.
In Southern Bukovina, the fruits of Rubus idaeus, Rubus spp., and Vaccinium myrtillus, and the flowers of Sambucus nigra were used for juice preparations. Interviewees also explained that the flowers of Sambucus nigra are used for making a fermented drink called "socată" (from the Romanian word 'soc'-Sambucus nigra). The flowers of Sambucus nigra are collected, and then 10 flower inflorescences, 1 kg of sugar and a lemon are added to 10 l of warm water and a teaspoon of dry yeast; after one day this mixture is bottled and stored in a cool place. The dried flowers also were named as suitable for preparing "homemade beer". The beer is lacto-fermented and may contain a small amount of alcohol. The same use was described in Roztochya (Western Ukraine), but it is called "sparkling drink" [7].

Homogeneity and Inhomogeneity of Wild Plants Use for Food Preparations
As the analysis of Factor of Informant Consensus reveals (Table 4), in Southern Bukovina among Romanians consistently used the same taxa for smoking of meat, seasoning and sarmale, while for tea and borshch more diversity was used. In Northern Bukovina, Romanians homogeneously use plants for jam and fermentation, while there was disagreement, meaning they made a not homogenous use of plant taxa, for alcoholic drinks, syrup and fresh food.

Past Uses of Wild Food Plants
In Romania, interviewees explained that in the past more forest products were used, mainly to generate income. In Northern Bukovina, their function as a food substitute for "deficit" products was mentioned, e.g., coffee was difficult to buy and so locals made coffee at home from the roots of Arctium lappa and Taraxacum campylodes. The decline in the use of wild plants for food was mentioned in both areas of Bukovina. Two interviewees in Northern Bukovina mentioned that in the past their grandparents used the leaves of Urtica dioica for making tea and soup. Likewise, tea made from Achillea millefolium and Matricaria chamomilla were named by 10% and 6% of interviewees, respectively, as past uses, again by their grandparents.
Compote and jam prepared from Vaccinium myrtillus and Rubus idaeus were mentioned as recently abandoned food practices by one interviewee in Southern Bukovina. Six percent of interviewees named jam made from Rosa rugosa as a recently abandoned practice.
Smoking meat with the wood of Fagus sylvatica was also mentioned by one person as a recently abandoned practice. Romanians in Romania did not mention past uses of wild food plants. Participatory observation in both study areas indicated that restaurants currently offer dishes with wild mushrooms and forest fruits, and they even sell dried wild forest fruits. In Southern Bukovina, local restaurants serve wild mushroom sauce, and desserts with wild forest fruits (blueberries and raspberries) were offered on the menu. In Northern Bukovina, a variety of forest fruits and plants were sold at local markets. In small local restaurants, tea made from forest fruits and plants was served, while blueberries were added to desserts, which in the description indicated that they were "forest" blueberries.
The use of wild food in our study populations plays a food supply role, as well as a culturally important role. For example, in Southern Bukovina wild foods were used to help generate income in the past and they are currently important in everyday cuisine.

Wild Edible Forest Plants
In both groups of Romanians, wild forest taxa were the most used, including Rubus idaeus (Romanians in Northern Bukovina (UaR) 40 Figure 6 and Table 3). These results are unusual as the local landscape of the region consists predominantly of flat lowlands with agricultural fields (Figure 2), and thus the distance to the forest and the fact that "most of the forests are situated in the mountains" were not seen as an obstacle. "We buy blueberries, raspberries and a variety of mushrooms at the market because those products grow in the forest up in the mountains", highlighted a Romanian woman from Northern Bukovina born in 1966. Our findings, therefore, show that forest products and forest taxa still play an important role in local ecological knowledge (LEK), which is consistent with Pieroni and Sõukand [24].
"We use forest berries [fruits]: blueberries, raspberries, blackberries, but they grow in the Carpathians, and you have to go far to harvest them", explained a young Romanian woman from Northern Bukovina born in 1983.
The better economic situation in the region is now allowing locals to buy forest products instead of collecting them themselves: "Before we were going to harvest blueberries, we started to go to the forest at 3 am; it was so hard and so time-consuming to collect blueberries. Now we buy them at the market", explained a Romanian woman born in 1947 in Northern Bukovina. "This year a friend brought me birch sap because it is too far to go to get it in the forest", stated a retired woman from Northern Bukovina. "We buy forest mushrooms and berries, they are tasty", asserted a retired Romanian woman in Ukraine. Romanians in Romania explained that in the past they used the forest fruits Vaccinium myrtillus, Fragaria vesca, and Vaccinium vitis-idaea to generate additional income in times of scarcity and economic crisis. However, nowadays they buy forest berries at the market or in shops.
Romanians in Ukraine also mentioned purchasing wild forest fruits, but mostly because "they grow far away in the mountains and one has to have time to harvest them", so it is much more convenient to buy them at the market.
Participatory observation at local markets revealed the sale of home-made dairy products and forest products (wild blueberries, mushrooms) in Northern Bukovina, while in Southern Bukovina it was mostly produced goods. The reason for this difference could be that in Romanian Bukovina milk collection from homes is still present (which was observed during fieldwork), so there is no need to process and sell milk yourself. Legislation in Ukraine allows the selling of forest products by locals, but there is currently discussion on banning the sale of dairy products by locals [65]. By law in Ukraine, the harvesting of forest products with commercial purposes has to be carried out with a special permit, which is a tax-based payment to local forest enterprises; however, this is not widely practiced due to bureaucratic complexity [14]. More active enforcement of this legislation may influence the use of wild forest products due to a reduction in the number of collectors and an increase in prices (to offset the additional cost of the permit). In Romania, the collection of forest products is free of charge for personal consumption, while it requires authorization for commercial purposes (according to article 58 of the Forest Code).
In both study areas wild plants including forest products continue to be used in daily cuisine, while in Southern Bukovina interviewees explained that those products also played a role in income generation in the past. Therefore, nowadays, in both areas the purchase of wild forest products was mentioned much more often than collecting them in the wild. This economic influence on wild product use is consistent with the findings of Stryamets [22], in Smăland, Sweden, where locals buy rather than collect non-wood forest products (NWFPs). So here, economic factors have highly influenced the use of forest products: first locals actively used them and sold them for additional income, but as the economic situation has improved, people have stopped selling them as they have money to buy them at local markets. This is the first step toward losing this LEK as children do not learn how and where to collect them; the next step involves people stopping cooking them (if these products are not available in shops). The situation in Swedish Smăland demonstrates that LEK has been eroded because of the healthy economic situation [7,22] and the consequent loss of the practice of foraging for NWFPs. One interviewee from Southern Bukovina explained that border creation reduced his opportunities to go to the forest, because most of the historical forest of Straja now belongs to Northern Bukovina; however, forest cover in Southern Bukovina is 63% compared to 37% in Northern Bukovina.

A Childhood Delicacy: The Past to Present Fashion of Dainty Foods
Rose syrup and jam made from the flower petals, minus the white part, of Rosa rugosa and Rosa centifolia were considered delicacies and used on special occasions. "In the past we used a specific rose for sweets and it was a delicacy; only respectable people made sweets with green walnuts and sweets with roses; they were for guests [Means that sweets with roses were used for only special occasions for guests]. I know that my mother made syrup and jams and locked them up [to be used only on special occasions and kept away from children]; they also made sherbet. The little ones went to the forest for raspberries and sold them in the town center to have money to buy school supplies, uniforms", explained a Romanian woman born in 1957. In the Ukrainian part of Bukovina, rose jam was used for religious celebrations as an additive to cakes and doughnuts. "We also prepare raw jam with rose flowers; what tasty buns you get with it! They are delicious", highlighted a Romanian woman from Ukraine, born in 1953. Nowadays, for confectionery purposes, one can buy rose syrup in specialty shops, for UAH 2700 (80 Euro) per kg, and the syrup is used in fashionable restaurants and by elite cakes producers. Historical Ottoman influence introduced a few elements which can still be found among Romanians living in Bukovina. One recipe is rose jam made with the petals of Rosa rugosa and Rosa centifolia. This recipe can also be found among other groups that were under Ottoman control, such as Hungarians [66] and Bosniacs [67]. Interestingly, this product was almost exclusively mentioned by Romanians in Romania. In addition, tea is also sometimes made from the petals of these roses. Both jam and tea can also be found in shops in Romania.
Another Ottoman element is sarma [68], which is locally called sarmale (mainly in Southern Bukovina) and găluşte (mainly in Northern Bukovina). This dish consists of meat and rice wrapped in leaves. For this purpose, the leaves of Tussilago farfara, Atriplex hortensis, Rumex spp. Brassica oleracea, Vitis vinifera, and Armoracia rusticana were used. One interviewee used horseradish leaves: "I make sarmale with horseradish [Armoracia rusticana], and loboda [Atriplex hortensis]. [Horseradish leaf] is placed between sweet-leafed cabbage rolls. We also do it with grape leaves", highlighted a Romanian woman born in 1955. All the mentioned taxa are common plants for this preparation; however, they were not previously reported in Romania [68].
The fact that homemade alcoholic drinks were mentioned in Southern Bukovina but not in Northern Bukovina may be the result of Soviet propaganda and punishment for preparing moonshine and homemade alcohol. However, alcoholic tinctures with a variety of forest fruits were used for medicinal purposes by Hutsuls in Bukovina [6].

Comparison with Hutsuls
Comparison with Hutsuls living in Bukovina reveals that 19 taxa are used by all four groups (see Figure 8). Hutsuls in Ukraine and Romania use the same taxa as Romanians in Ukraine for recreational tea: Arnica montana, Matricaria chamomilla, and Achillea millefolium. Hutsuls in Romania and Ukraine and Romanians in Romania, however, use Viburnum opulus and Humulus lupulus for this purpose (see Figure 8).
The use of Plantago major as a tea has also been documented among Hutsuls in Ukraine, but not among Boykos [7]. Cross-border comparison of wild plant uses shows that Equisetum spp., Acer spp., Aronia melanocarpa (Michx.) Elliott, Picea abies (L.) H. Karst., Sorbus aucuparia L., and Chenopodium album L. were used only by Hutsuls.
Cross-cultural analysis in Ukraine reveals 29 shared wild taxa, whilst five of them (Arctium lappa, Plantago major, Crataegus monogyna, Trifolium spp., and Betula spp.) are specific for Northern, but not Southern Bukovina. In Romania, cross-cultural analysis of food plants used by Romanians and Hutsuls in Southern Bukovina reveals the use of 22 shared taxa. in Ukraine for recreational tea: Arnica montana, Matricaria chamomilla, and Achillea millefolium. Hutsuls in Romania and Ukraine and Romanians in Romania, however, use Viburnum opulus and Humulus lupulus for this purpose (see Figure 8). The use of Plantago major as a tea has also been documented among Hutsuls in Ukraine, but not among Boykos [7]. Cross-border comparison of wild plant uses shows that Equisetum spp., Acer spp., Aronia melanocarpa (Michx.) Elliott, Picea abies (L.) H. Karst., Sorbus aucuparia L., and Chenopodium album L. were used only by Hutsuls.
Cross-cultural analysis in Ukraine reveals 29 shared wild taxa, whilst five of them (Arctium lappa, Plantago major, Crataegus monogyna, Trifolium spp., and Betula spp.) are specific for Northern, but not Southern Bukovina. In Romania, cross-cultural analysis of food plants used by Romanians and Hutsuls in Southern Bukovina reveals the use of 22 shared taxa.
The Jaccard similarity index (JI) calculated for Romanians on the two sides of the border is 45.65. The JI for taxa named by at least 10% of interviewees is 43.33. Comparison with other studies [4,6] shows that the calculated similarity index with regard to wild taxa used for food within the Hutsul ethnic group across the border is 55 when considering all taxa and 44 when considering only those taxa mentioned by at least 10% of interviewees (Table 4).
Hutsuls and Romanians living in Romania share 22 taxa (including cultivated ones) used for food, with a JI of 53.66.
In Ukrainian Bukovina, both Hutsuls and Romanians use a greater diversity of taxa, whereas Romanian Bukovina Hutsuls and Romanians use fewer taxa but with greater intensity (based on DUR) (Figure 9). The Jaccard similarity index (JI) calculated for Romanians on the two sides of the border is 45.65. The JI for taxa named by at least 10% of interviewees is 43.33. Comparison with other studies [4,6] shows that the calculated similarity index with regard to wild taxa used for food within the Hutsul ethnic group across the border is 55 when considering all taxa and 44 when considering only those taxa mentioned by at least 10% of interviewees (Table 4).
Hutsuls and Romanians living in Romania share 22 taxa (including cultivated ones) used for food, with a JI of 53.66.
In Ukrainian Bukovina, both Hutsuls and Romanians use a greater diversity of taxa, whereas Romanian Bukovina Hutsuls and Romanians use fewer taxa but with greater intensity (based on DUR) (Figure 9).
The calculation of JI without cultivated taxa revealed even more similarity (Table 5) in uses within a country: JI for Romanians and Hutsuls in Romania is 61.11, and for Romanians and Hutsuls living in Northern Bukovina it is 52 (data on wild plant taxa used for food by Hutsuls is from [6]). The homogenization of LEK among Romanians living in Ukraine and Hutsuls, which live in different environments but within same country, may have been due to Soviet influences as discussed by Pieroni and Sõukand [5], e.g., propaganda of wild plant use at schools as the availability of local foods was inadequate. An older Romanian interviewee, who was born in Ukraine in 1953 and worked at the library, explained that she and a school biology teacher have made an excursion path into the forest for two km where they explain to children the medicinal and food plants that growth there. "It feels so good when kids go there and ask about the plants and collect plants. It is so important to teach kids", explained the retired librarian. The calculation of JI without cultivated taxa revealed even more similarity (Table 5) in uses within a country: JI for Romanians and Hutsuls in Romania is 61.11, and for Romanians and Hutsuls living in Northern Bukovina it is 52 (data on wild plant taxa used for food by Hutsuls is from [6]).

"It feels so good when kids go there and ask about the plants and collect plants. It is so important to teach kids", explained the retired librarian. Figure 10 shows, in particular, the prevalence of Achillea, Betula, Matricaria, Taraxacum, Tilia, Tussilago, and Viburnum spp. food uses among Romanians in Ukraine and of Atriplex, Rosa, Sambucus, and Thymus spp., as well as of Vaccinium myrtillus, among Romanians in Romania.   These remarkable differences correspond again, following the pattern we outlined for plant preparations, to the most prototypical wild food plants occurring in the foodscapes of Ukraine and Romania: Betula, Taraxacum, Tilia, and Viburnum are particularly crucial plants in the Eastern Slavic and wider post-Soviet wild food domain [33,[69][70][71], while Atriplex, Thymus, and Vaccinium spp. are salient ingredients of the Romanian foodscape [32,37]. These data show again how the wild foodscapes of Romanians have been diversely influenced in the past century by national cuisines on both sides of the border, possibly via intense contact and cohabitation with neighbors (Ukrainians in Ukraine and Romanians in Romania, respectively), facilitated by intermarriages and the celebration of an atheistic, non-religious ethos which Communism provided.

Attitudes and Perceptions
Cross-border Bukovina is very diverse and multifarious. Nice lawns with magnolias and decorative trees neighbor yards with home gardens growing a variety of crops; a huge jeep car is followed by horses. In a local pizza place a young woman buys pizza for the family dinner (instead of cooking it herself which is the more common and much cheaper practice in rural areas, e.g., for the price of three pizzas one can feed the family for a week), while in the next house we see home-baked bread and a cow kept for milk for the children. The interviewees explained that most of the young people are abroad for seasonal work. Women or grandparents stay at home to take care of the kids. Visually, the differences in the level of income are seen very clearly, with expansive home and fence decoration and a wooden roof house close by.

"There Is No One to Cook for" in Southern Bukovina
The demographical situation in both Southern and Northern Bukovina regions over the past several years has changed dramatically-the younger generation has moved to the cities or richer areas of the European Union. Elderly individuals are the ones who remain in the region. There are a few current trends: (1) the younger generation sends back money to build houses; (2) the men of the household leave for seasonal jobs and then return; and (3) younger individuals move out and never come back. During our interviews we noted all of these trends. Some people, including several middle-aged men who worked in Germany, explained that they have tried "the hard living in a foreign land" and will eat "bread and water", but they would never go back. Others explained that because there is nowhere to work in Bukovina they (or at least someone from their family) have to go for seasonal work to earn money. There were cases in which children were left with grandparents, while parents went abroad and "talked with and educated kids via the Internet", but they physically did not see them for years. We also observed the huge newly built houses in the area that stand empty (see Figures 3 and 4). All this trend has influenced the use of wild plants for food. The youngsters have left on their own, there is a missing chain (parents are abroad and it is not possible to learn the way of wild plant use via the internet) in the transmission of knowledge. Economic influence also reduces the need to collect wild plants and the last trend the absence of children close to grandparents. A Romanian woman, born in 1947, explained that because there are no younger children or grandchildren left with her, she has no one to cook wild foods for any more: "I have bought one liter of blueberries. Now I live alone, and I have no one to cook for. Before I was cooking a lot; now my kids left, so I don't need so much for myself".

"Like in Italy" in Northern Bukovina
In Northern Bukovina besides the emigration trend, we observed how the influence of experience local's gain abroad was transmitted to local cuisine. Meanwhile, the locals sometimes perceived the wild food plants as "famine food or poor food". A woman born in 1928 explained that there was no Holodomor (the artificial famine) like in other parts of Ukraine, so they do not use many wild plants for food. This indicates that there is a view of wild plants as famine foods, which is in line with previous studies [7,10]. "This is păpădie (Taraxacum campylodes), we use it for salads, like in Italy", explained a Romanian woman born in Ukraine in 1966. "I spent 8 years working in Italy; I just came back. I buy tea, I don't collect it", declared a 54-year-old man from Northern Bukovina.
"I have tea from Italy, I don't drink tea from local herbs", stated an older Romanian woman in Northern Bukovina. "We are not poor to drink herbal tea", explained a retired Romanian woman. Nowadays some respondents see wild food as a famine or peasant food, which is in agreement with many findings from contemporary Europe [10,28].
Two interviewees explained that they do not collect Origanum vulgare nor buy bay leaves (Laurus nobilis) because they obtain them from Italy.
Among Romanians in Ukraine, a widespread response was that they buy tea, instead of collect it from nature: "We don't make other teas, the majority we buy. There are big and small packages, I think they are called gruzinskii", explained a Romanian woman born in Ukraine in 1939. One pensioner, a Romanian women living in Ukraine, asserted that "we are not poor, we have tea and coffee from Italy", so there is a view of wild food as "poor" food, in contrast to food coming from abroad (considered elitist, which has Soviet roots when products from abroad could only be found in specific shops in capital cities, and those who could afford them were seen as wealthy).
Globalization and the homogenization of cultures, languages and natural resource use is a trend nowadays [40,41].
In addition, in both of our study populations, results show that an open work market has negatively influenced wild food use, including its abandonment and decline, due to: 1.
The emigration (both seasonal and permanent) of young and middle-aged individuals from border areas to other European countries. New knowledge and practices of wild plant use as a result of traveling and working abroad, e.g., "Salad like in Italy", and "I don't collect herbs from here [the surrounding environment], I have tea from Italy". 2.
The idea of "no one to cook for", which involves a reduction in the use of wild foods due to depopulation of rural border areas by younger generations, leaving only pensioners in the region. This is about unwillingness to invest time in elaborate recipes (or hard-to-find ingredients) because of the lack of loved ones to motivate such an effort.

3.
The decline in the use of wild plants because of replacement by mass market products, e.g., "I have Origanum from Italy; I don't collect it anymore". 4.
The valorization of forest products and higher income level which allows people to buy forest products instead of harvesting them from the wild, e.g., "We buy blueberries".
Our results demonstrate the use of wild plants was as a part of cultural identity and self-actualization. It is shown with the childhood memories, or use of wild plants for specific, time-requiring dishes (e.g., smoking meat).
Living in same ecological conditions, but with different socio-economic scenarios, we discover differences in the use of wild foods by the same ethnic group (Figure 11). Problems with infrastructure and the lack of job opportunities in Ukrainian Bukovina compel locals to be more dependent on available wild food resources, while in Southern Bukovina the income-generating function of wild foods is confined to the past. The use of wild plants that are strongly associated with local cultural identity and are present in local culinary traditions [72], the maintenance of wild taxa used as childhood treats, and specific local culinary recipes (e.g., smoking meat, afinată, socată, sarmale and green borshch) are less likely to disappear from local cuisines. However, our results demonstrate the strong influence of an open work market and social migration on the use of wild plants. Rapid changes in lifestyle and habits are one explanation for the abandonment of wild food use, which is consistent with Serrasolses et al. [72].
The majority of food taxa used by Romanians in Ukraine, especially for making tea, can also be used for medicinal purposes. This food-medicinal continuum when comparing the two groups was also observed in Sõukand and Pieroni [6].

However, our results demonstrate the strong influence of an open work market and social migration on the use of wild plants. Rapid changes in lifestyle and habits are one explanation for the abandonment of wild food use, which is consistent with Serrasolses et al. [72].  In Bukovina, 51 taxa (46 wild taxa plus 5 cultivated taxa with uncommon uses) were used for food, compared to 40 taxa recorded by Sõukand and Pieroni [4]. This number, however, is lower than the 70 taxa recorded in Polissya Region [24], yet higher than in Roztochya with 26 taxa [7], or the 44 taxa used in Maramures , [33].
Romanians in Ukraine used four wild taxa (Urtica dioica, Rumex acetosa, Rumex spp., and Thymus spp.) for soup preparations, while Romanians in Romania used only two taxa (Urtica dioica and Atriplex hortensis). In other parts of Ukraine the number of plants use for "green" soup reaches 21 taxa [26]. In Southern Bukovina, Atriplex hortensis is not seen as wild because it grows in gardens, similar to that of Rumex acetosa in the area of Roztochya, where this taxon grows in yards and gardens [22].
Birch sap was widely used in Northern Bukovina as a refreshing drink and also fermented for winter time. It is popular in other parts of Ukraine and Eastern Europe as well [5,71], and thus could have a Soviet origin.
The flowers of Robinia pseudoacacia were mentioned as a famine food during times of scarcity in Polissya Region [24]. The possible attenuation in use of Atriplex hortensis by Romanians in Northern Bukovina may be related to the fact that it is seen as a famine food [73]. The prevalent use of recreational tea by Romanians in Ukraine could have Soviet roots, as teatime and herbals tea were promoted during this era. Sweets being the dominant preparation mode in Southern Bukovina may be explained in a couple of ways: the "deficit" of sugar during economic crises and sweets being seen as rich people's food, and the Turkish influence of using jams and sweets. The difference in the use of winter preserves and fermenting may be due to the unstable economic situation in Northern Bukovina, which forces people to have their own food security system for winter time and times of uncertainty.
The taste of wild foods was also one of the factors influencing the use of plants, e.g., jam made from Rosa rugosa is considered to be a delicacy, and nowadays there is a trend toward the valorization of products made from Rosa rugosa in both areas of Bukovina. Studies have demonstrated that taste is culturally developed [74]. Therefore, in our case taste was not the main factor influencing wild food use [72].
The use of wild foods not only serves nutritional and safety-net functions [75], but it is a source of self-actualization and contributes to well-being [42], e.g., "I cook as my mom and grandma used to cook, using wild herbs". Complex human-nature relationships are formed with the use of wild foods growing in the surrounding landscape, creating a unique local cuisine. However, socio-economic and governance systems have produced differences in uses by the same ethnos in the same environment. An improved economic situation leads to a decline in the use of wild taxa for food, as well as harvesting practices (purchasing food items at the market instead of collecting them from the surrounding landscape) and cooking practices, e.g., "it is hard to cook and there is no one to cook for".
Differences across the border are remarkable: along with the use of 21 shared taxa, we recorded 25 different wild food taxa. The most remarkable differences between the two sides were related to mode of preparation. We suggest that those differences are the result of the influence of intense contact and cohabitation with neighbors (Romanians on the Southern Bukovina side and Ukrainians on the Northern Bukovina side). In Romania, Bukovinians were part of a larger group and did not have to preserve any ethnic belonging and cultural identity. While in Northern Bukovina, Romanians had to somehow integrate with Ukrainians, yet remain Romanian in order to save their cultural identity. In Northern Bukovina, interviewees mentioned that their children were studying in Ukrainian universities; even though schools in the region are Romanian, they study Ukrainian and some teachers are Ukrainian. The peaceful coexistence of these two ethnic groups has resulted in intermarriages and close connections. Interviewees also highlighted Moldova as a state with a similar language (they use Romanian with a Cyrillic alphabet) and education in Moldavian institutes during Soviet times.
Therefore, the factors possibly influencing local cuisine and the use of wild food plants include: 1.
The border that has divided Bukovina for the last 80 years has resulted in different socio-political scenarios and thus in different food behaviors and the use of wild plants in local cuisine. Long-standing borders have had a tangible effect in shaping divergent wild plant foodscapes, since the respective national states of Northern and Southern Bukovina, and possibly different neighbors, have shaped the Romanian dining table in different ways.

2.
Intermarriage and neighbor influence. At least three interviewees in Northern Bukovina explained that they were married to a Ukrainian, which may have influenced their food behavior: "I cook green borshch as Ukrainians do" and "My daughter-in-law is Ukrainian, from Kolomyya; she cooks 12 dishes for Christmas Eve, and she teaches me". Another male interviewee stated: "In the neighboring Novoselecjk region they ferment apples and melons, but we don't". 3.
Economic differences: in order to smoke meat one has to be able to afford it, and during Soviet times meat was "deficit", while during the economic crisis between 1990 and 2000 rural individuals could not afford it. In contrast, herbal teas are easily affordable, and among Romanians it was twice as popular in Northern Bukovina as in Southern Bukovina. The use of birch sap clearly has Soviet roots as it was promoted as a "healthy and tasty drink". Winter preserves, as a way to survive during economic crises, are still popular in Northern Bukovina as a food security practice. 4.
Market influence: Romanians live in close proximity to other ethnic groups with whom they interact at local markets; for example, participatory observation in Northern Bukovina has revealed the possible exchange of culinary experiences at "babushka" markets [65].

5.
The media: local newspapers and television food shows may also influence local cuisine, as recipes for different dishes have been published in the local press.
The latest UN report [76] highlighted that in terms of global food issues locally grown foods and the use of wild foods from local landscapes are the answer to the challenges that humankind currently faces. That is why documenting and discussing LEK on wild food use is a crucial and timely endeavor.

Conclusions
Contemporary use of wild taxa by Romanians in Bukovina Region was diverse and different across the border. Romanians in Romania use fewer taxa in a less intensive way, while Romanians in Ukraine use more diverse species and have more diverse uses, including those that support food security in winter time. In the wild food domain, Romanians living in Bukovina used 46 plant taxa (plus 5 cultivated taxa with uncommon uses). Despite the flat landscape with extensive agricultural fields, Romanians on both sides of the border used forest taxa the most as wild food.
The limitation of the study is that the two groups of Romanians do not present a statistically significant difference in the use of plant categories, therefore the qualitative results of this study represent the contemporary use of wild plant taxa for food purposes, showing 566 DURs.
Limitations of the study: in both case study areas the women were the dominating (80%) interviewees; therefore we consider this division as relevant to these conditions (in the gender strictly of the older generation the women dominated) and qualitative methods. As in both areas the help of the field assistant was used, some small details of the interviews might be lost in the translation.
Our results show that the use of wild food plants in Bukovina is more similar between ethnic groups (Hutsuls) within the same country (Romania or Ukraine) than within groups across the border (Romanians living in Romania and Ukraine), which supports the main hypothesis of the DiGe (Divided Generations project) that socio-political scenarios influence the use of wild foods. Indeed, cross-border studies can greatly contribute to enhance our understanding of the impacts of political (and consequently social and economic for instance) contexts on the local ecological knowledge. This can be crucial to shape effective policies according to the perceptions and management of local resources adapted to different political contexts. Such policies can be especially important in areas rich of biological and/or cultural diversity, which therefore would require context-based conservation and valorization policies.
The 80 years spent living under different governance systems has resulted in different ways of using wild plants in daily cuisine. The use of food plants by Romanians is more markedly shaped by intermarriage and neighbor influence (through media and local markets), as well as the recent phenomenon of globalization/open work market, as a result making use of some plants similar to those found in countries where interviewees worked (e.g., Italy). The improved economic situation (the possibility of buying produced food instead of collecting it in the wild) and the availability of industrially produced goods have also influenced current uses, e.g., decrease in the use of wild plants in everyday cuisine. Depopulation of rural areas and a growing disconnect with nature has also significantly influenced the decline in the skills and practices of wild plant use. In addition, the valorization of forest products and a higher income level allows for buying forest products instead of harvesting them from the wild.
This research gives the opportunity to understand the dynamic structure of local cuisine, influences by the socio-political scenarios, globalization, intermarriage and coexisting of different cultures, and media influence, market flow of products as well as the economic situation which allows limitation of wild plants use. Based on these results, the prognoses of more disconnection with nature, less wild plants use for everyday cuisine could be reached. Therefore, the internal global crises events, e.g., the COVID-19 pandemic or issues with food supply in the remote areas might increase the wild plant use for food.
Complex human-nature relationships are formed with the use of wild foods growing in the surrounding landscape, creating a unique local cuisine. There is a need for further research into how socio-political scenarios under conditions of globalization, in terms of the flow of people, investment, market product and knowledge, influence LEK and food habit changes, focusing on biocultural values and dynamics of local cuisine.
The use of wild food as a self-actualization and contribution to well-being also requires future studies. Further research is needed to explain food uses for cultural purposes; for example, religious celebrations. Another issue that was frequently mentioned by locals and seen as an important culinary practice, and thus needs more thorough analysis and consideration, including cross-border comparison, is food habits connected to ceremonies and ritual behaviors.
In the framework of recent debates on the significance of wild food plants, especially during the Covid-19 crisis, current research is vital in terms of the application of LEK and understanding the driving forces of wild plant use. The next issue that demands research is home-grown foods as a food security measure. During the participatory observations and during interviews, locals named the food gardens close to homes as an important source of both supplementary food and "healthy self-growing food". The use of wild foods as ethnomedicine for humans and for animals is another important subject for our future research.
