Meeting Abstract P3.41  Jan. 6  Evolution of orbit orientation and binocular vision in primates and other euarchontans. HEESY, C.P.; Midwestern Univ. metacephalon@gmail.com Orbit orientation is a critical component of visual field construction in primates as well as in other mammals. It has been hypothesized that orbit convergence (the degree to which the orbits face in the same […]

Meeting Abstract P3.46  Jan. 6  Evolution of fossoriality in mammals: does burrowing behavior drive an evolutionary ratchet? HOPKINS, SSB; National Evolutionary Synthesis Center shopkins@nescent.org Some ecomorphological specializations create an evolutionary �ratchet,� a term used to describe irreversible morphological evolution. Hypercarnivory, for example, has evolved many times in the history of mammalian carnivores, and invariably leads to the […]

[…]

Meeting Abstract P3.27  Jan. 6  Effects of Starvation Selection on Energy Storage and Metabolic Rates in Drosophila melanogaster SENEVIRATNE, E.*; GIBBS, A. G.; University of Nevada, Las Vegas stargiggles4evr@aol.com We have begun selection for starvation resistance in replicated populations of Drosophila melanogaster. The starting populations had served as starved control populations for a series of desiccation-selected lines, […]

Meeting Abstract P3.128  Jan. 6  Effects of Social Defeat on Immune Responses in Siberian Hamsters CHESTER, E.M.*; BONU, T.; DEMAS, G.E.; Indiana University; Indiana University; Indiana University emcheste@indiana.edu Prolonged exposure to physical stressors causes decreased immune function as a result the activation of the hypothalamo-pituitary-adrenal (HPA) axis and the subsequent release of glucocorticoids. Likewise, social interactions can […]

Meeting Abstract P3.113  Jan. 6  Effects of Body Size and Sex on Cardiac Citrate Synthase Activity in Rainbow Trout (Oncorhynchus mykiss) ANANTHAKRISHNAN, Gayathri*; BATTIPROLU, Pavan K; RODNICK, Ken J; Idaho State University anangaya@isu.edu Citrate synthase, the initial enzyme of the tricarboxylic acid cycle, is a key enzyme for mitochondrial oxidation and energy production. Evidence also suggests that […]
