LACY, Eva L*; WILSON, Mark E; Emory University: Social Rank Affects Feeding Patterns and Metabolic Hormones in Female Monkeys Chronic social stress can disrupt reproductive physiology and may involve significant changes in energy balance. Details of the behavioral and endocrine features of energy balance in socially stressed animals are lacking, however. To address the energetic […]

ROOSENBERG, A.S.*; TIELEMAN, B.I. ; WILLIAMS, J.B. ; KLASING, K.C. ; Ohio State University, Columbus; University of Missouri, St. Louis; Ohio State University, Columbus; University of California, Davis: Seasonal trends in immune function of tropical house wrens In wild avian populations, relatively little is known about variation in immunological capabilities. We studied the constitutive innate […]

AYERS, M*; MOORE, F; BAGATTO, B; University of Akron; University of Akron; University of Akron: Searching for Critical Windows in the Develoipment of the Zebrafish Cardiovascular System Fluctuations in aquatic oxygen concentrations are often experienced by developing fish and can have significant implications on the adult phenotype. It has been suggested that there are certain […]

SCHOLNICK, D.A.*; BURNETT, L.E.; Eckerd College, St. Petersburg; Grice Marine Lab, College of Charleston: Respiratory Responses to Bacterial Exposure in the Penaeid Shrimp Litopenaeus vannamei During Locomotory Activity and Recovery Aerobic metabolism is significantly reduced in crustaceans following a bacterial challenge. Current evidence suggests that the metabolic response is a result of bacteria and hemocytes […]

VITOUSEK, Maren N.*; MITCHELL, Mark A.; Princeton University; Louisiana State University: Reproductive pattern and follicular development in the Galapagos marine iguana (Amblyrhynchus cristatus) Female Galapagos marine iguanas (Amblyrhynchus cristatus) typically reproduce biennially, producing a clutch that represents 18-28% of female body weight. During periods of plentiful food availability females may reproduce in consecutive years; when […]

The planarian, Dugesia ryukyuensis, has three populations in […]

SWANSON, DL*; THOMAS, NE; University of South Dakota: Relationship of plasma triglycerides and creatine kinase to overnight temperature in winter acclimatized small birds Plasma triglyceride (TG) levels and creatine kinase (CK) activity may increase during long-distance flights in migratory birds, TG as an additional lipid fuel source and CK as a result of flight-induced muscle […]

PAITZ, Ryan*; JANZEN, Fredric; BOWDEN, Rachel; Illinois State Univ.; Iowa State Univ.; Illinois State Univ.: Relationship between plasma and egg yolk steroid levels in the painted turtle In species that undergo rapid egg formation (e.g., birds), steroid concentrations in plasma and those in yolk often closely match. In contrast, in species in which the process […]
