Mechanisms of bite force production and their relationship with diet in Neotropical leaf-nosed bats
Meeting Abstract 90.7 Thursday, Jan. 7 Mechanisms of bite force production and their relationship with diet in Neotropical leaf-nosed bats SANTANA, S.E.*; DUMONT, E.R.; DAVIS, J.L.; UMass Amherst; UMass Amherst; UMass Amherst ssantana@bio.umass.edu In terms of cranial morphology and diet, Neotropical leaf-nosed bats (family Phyllostomidae) are one of the most diverse groups of mammals. This morphological diversity […]

Unpredictable Food Availability as an Ethologically Relevant Chronic Stressor in European Starlings (Sturnus vulgaris)
Meeting Abstract 90.3 Friday, Jan. 7 Unpredictable Food Availability as an Ethologically Relevant Chronic Stressor in European Starlings (Sturnus vulgaris) BAUER, C.B.*; GLASSMAN, L.G.; ROMERO, L.M.; Tufts University; Tufts University; Tufts University carolyn.bauer@tufts.edu Both the fight-or-flight and hypothalamic-pituitary-adrenal (HPA) axis responses have been well studied in chronically stressed European starlings. In this study we attempted to characterize […]
The long-term developmental and physiological effects of larval environmental stressors are condition-dependent in wood frogs
Meeting Abstract 90.2 Friday, Jan. 7 The long-term developmental and physiological effects of larval environmental stressors are condition-dependent in wood frogs WARNE, R.W.*; CRESPI, E.J.; Vassar College Biology; Vassar College Biology rw.warne@gmail.com Exposure to stressors during early development can impact physiological function, behavior, and fitness in adult life stages in vertebrates. However, the specific mechanisms that link […]
Stress begets stress elevated yolk corticosterone impacts oxidative stress in chicks
Meeting Abstract 90.5 Friday, Jan. 7 Stress begets stress: elevated yolk corticosterone impacts oxidative stress in chicks HAUSSMANN, M.F.*; BOWDEN, R.M.; Bucknell Univ.; Illinois State Univ. mfh008@bucknell.edu Early embryonic exposure to maternal glucocorticoids (GCs) can broadly impact physiology and behavior across phylogenetically diverse taxa. The transfer of maternal GCs to offspring may be an inevitable cost associated […]
