CORT and parasitic infectious disease: Many stressors have been observed to produce effects on CORT levels including physical factors (temperature: Lutterschmidt & Mason, 2009; Telemeco & Addis, 2014; extreme weather events: Romero & Wikelski, 2001) and biotic stressors such as predation (Thaker, Lima, & Hews, 2009), social competition (Comendant, Sinervo, Svensson, & Wingfield, 2003), and especially parasitic infections (Hanley & Stamps, 2002; Sperry, Butler, Romero, & Weatherhead, 2009).
