Behavioral plasticity mediates life history trade-offs in response to habitat disturbance
Meeting Abstract 57.4 Saturday, Jan. 5 Behavioral plasticity mediates life history trade-offs in response to habitat disturbance WILLIAMS-SIEG, K. A.*; MILES, D. B.; Ohio University kw114105@ohio.edu Environmental variation is known to induce trade-offs, which requires shifts in energy allocation among behaviors involved in reproduction, parental care and self-maintenance, thereby affecting reproductive success and survival. We examined behavioral […]
Maternal stress as a driver of adaptive phenotypic responses in offspring
Meeting Abstract 56.1 Saturday, Jan. 5 Maternal stress as a driver of adaptive phenotypic responses in offspring SHERIFF, MJ*; LOVE, OP; University of Alaska Fairbanks mjsheriff@alaska.edu Maternal stress has become widely recognized as a driving factor affecting offspring phenotypes, and evolutionary biologists and medical practitioners are investing great effort in determining the role of maternally-derived stress (MDS) […]

Early Developmental Stress Alters HVC but not RA size in Male Zebra Finches
Meeting Abstract 56.3 Saturday, Jan. 5 Early Developmental Stress Alters HVC but not RA size in Male Zebra Finches CARRUTH, L.L.*; SHAHBAZI, M.; Georgia State University; Georgia State University lcarruth@gsu.edu Stress has long lasting effects on animal physiology, development, behavior, reproductive success and survival. The effects of stress are mediated by glucocorticoids, such as corticosterone (Cort), via […]
Does developmental stress modulate reproductive tactics in the zebra finch

CRINO, O.L.*; DRISCOLL, S.C.; PRATHER , C.T.; BREUNER, C.W.; University of Montana; University of Montana; University of Montana; University of Montana ondicrino@gmail.com The long-term effects of developmental stress on phenotype and performance are well-known. In comparison, the effects of developmental stress […]
Developmental corticosterone exposure is correlated with exploratory behavior and learning flexibility in Florida scrub-jays (Aphelocoma coerulescens)
Meeting Abstract 56.4 Saturday, Jan. 5 Developmental corticosterone exposure is correlated with exploratory behavior and learning flexibility in Florida scrub-jays (Aphelocoma coerulescens) BEBUS, SE*; SMALL, TW; SCHOECH, SJ; University of Memphis; University of Memphis; University of Memphis sebebus@memphis.edu The level of corticosterone (CORT, the avian glucocorticoid), to which an individual is exposed during development can have long-term […]
Why are muscle fibers so large Solving diffusion problems to attain maximal cell size
Meeting Abstract 55.6 Saturday, Jan. 5 Why are muscle fibers so large? Solving diffusion problems to attain maximal cell size KINSEY, S.T.; University of North Carolina Wilmington kinseys@uncw.edu Muscle fibers are among the largest cell types, but while diffusion appears to limit maximal fiber size, the selective pressures that control minimal size are unclear. During animal growth, […]
Risky Fats and Antioxidant Arsenals in Cold- and Warm-Bodied Fishes
Meeting Abstract 55.2 Saturday, Jan. 5 Risky Fats and Antioxidant Arsenals in Cold- and Warm-Bodied Fishes CROCKETT, E.L.; Ohio University crockett@ohiou.edu Fishes living at cold body temperatures are rich in biological membranes that are fortified with polyunsaturated fatty acids (PUFA). PUFA are particularly susceptible to lipid peroxidation, a process initiated by reactive oxygen species (ROS) and propagated […]
