SEASONAL CHANGES IN BASAL AND STRESS-INDUCED PLASMA CORTICOSTERONE IN A SONORAN DESERT MALE SONGBIRD
Meeting Abstract 47.4 Jan. 6 SEASONAL CHANGES IN BASAL AND STRESS-INDUCED PLASMA CORTICOSTERONE IN A SONORAN DESERT MALE SONGBIRD DEVICHE, P.J.; Arizona State University deviche@asu.edu Changes in baseline and stress-induced plasma corticosterone (CORT) concentrations have been documented in many avian species. However, few studies in intact free-ranging birds have investigated systematic variations of these concentrations throughout the […]
Reproductive and Immune Consequences of Intermittent Increases in Corticosterone in the White-Crowned Sparrow Zonotrichia leucophrys gambelii An Experimental Paradigm for Repeated Acute Stressors
Meeting Abstract 47.6 Jan. 6 Reproductive and Immune Consequences of Intermittent Increases in Corticosterone in the White-Crowned Sparrow Zonotrichia leucophrys gambelii: An Experimental Paradigm for Repeated Acute Stressors. BOYD, EB*; BUSCH, DS; WINGFIELD, JC; Univ. of Washington ellen@boydvet.com Animals secrete glucocorticoids in response to stressful events. These elevated levels of glucocorticoids suppress reproduction and regulate the immune […]
Hormone-behavior correlations vary with energetic stress in breeding male tree swallows (Tachycineta bicolor)
Meeting Abstract 47.7 Jan. 6 Hormone-behavior correlations vary with energetic stress in breeding male tree swallows (Tachycineta bicolor) CZARNOWSKI, M.R.*; LOMBARDO, M.P.; POWER, H.W.; Rutgers University; Grand Valley State University; Rutgers University czar@wildbehavior.net We previously demonstrated that clipping the primary wing feathers of breeding male tree swallows (Tachycineta bicolor) decreased certain parental care behaviors such as nestling […]
Flight induced oxidative stress and Hsp70 expression in aging honey bees, Apis mellifera

Effect of UV-B radiation and skin color on survival and growth in larval amphibians
Meeting Abstract 47.5 Jan. 6 Effect of UV-B radiation and skin color on survival and growth in larval amphibians BANCROFT, B.A.**; BLAUSTEIN, A.R.; Oregon State University; Oregon State University bancroft@science.oregonstate.edu Ultraviolet-B radiation (UV-B) negatively affects many living organisms, especially amphibians. However, UV-B has been present throughout evolutionary history and amphibians have a number of strategies to avoid […]
