Meeting Abstract 38.11 Tuesday, Jan. 5 Science based criteria for assessing humane euthanasia BRYER, PJ*; DAVIS, BL; SUTHERLAND, MA; Lamar University, Beaumont TX; Texas Tech University, Lubbock TX; AgResearch, Hamilton NZ pamela.bryer@lamar.edu Humane methods of on-farm euthanasia are currently a topic of interest both for producers and the public. There are many different views on what is […]
Road disturbance and its impact on stress physiology and growth in young Florida scrub-jays
Meeting Abstract 38.2 Tuesday, Jan. 5 Road disturbance and its impact on stress physiology and growth in young Florida scrub-jays RENSEL, M.A.*; SCHOECH, S.J.; Univ. of Memphis; Univ. of Memphis mrensel@memphis.edu Anthropogenic disturbance can be a major source of physiological stress that may go undetected in avian species. Understanding the impact of human influence on stress in […]
Relationship between corticosterone, immune response, and parasite load in two species of tropical anurans (Chaunus marinus and Agalychnis callidryas)
Meeting Abstract 38.5 Tuesday, Jan. 5 Relationship between corticosterone, immune response, and parasite load in two species of tropical anurans (Chaunus marinus and Agalychnis callidryas). MENDONCA, M.T*; PATTERSON, S.T.; Auburn University mendonca@auburn.edu There is little information on patterns of stress responsiveness and immunocompetence in amphibians in general and in tropical species of amphibians in particular. We explored […]

Meeting Abstract 38.1 Tuesday, Jan. 5 Interactions between social stress and resource availability on tadpole growth, development and physiology CRESPI, Erica J*; WARNE, Robin W; Vassar College; Vassar College ercrespi@vassar.edu Exposure to stressors during early development have been shown to have important impacts on physiological function, behavior, and fitness during later life stages in vertebrates, but the […]
Environmental and life-history correlates of glucocorticoid physiology in an arid-country bird
Meeting Abstract 38.7 Tuesday, Jan. 5 Environmental and life-history correlates of glucocorticoid physiology in an arid-country bird BUTLER, L.K.*; HAYDEN, T.J; ROMERO, L.M.; The College of New Jersey; Engineering Research and Development Center; Tufts University lbutler@tcnj.edu We investigated hypothalamic-pituitary-adrenal axis activity in a free-living migratory songbird that exhibits an uncommon suite of environmental and life-history traits. Painted […]
Corticosterone, corticosteroid-binding globulin, and free corticosterone, 24-72 hours following an acute stressor in a wild population of white-crowned sparrows
Meeting Abstract 38.4 Tuesday, Jan. 5 Corticosterone, corticosteroid-binding globulin, and free corticosterone, 24-72 hours following an acute stressor in a wild population of white-crowned sparrows MALISCH, J.L.*; CRINO, O.L; BREUNER, C.W.; University of Montana jessica.malisch@mso.umt.edu The acute stress response is typically assumed to be a short-term (minutes to hours) rise in circulating glucocorticoid levels. However, acute stress […]
