HAGERTY, B.E.; SANDMEIER, F.; TRACY, C.R.; University of Nevada, Reno; University of Nevada, Reno; University of Nevada, Reno: Quantitative review of the adequacy of knowledge of different age stages of the desert tortoise, Gopherus agassizii Implementation of effective management strategies to recover the federally-listed Mojave population of Gopherus agassizii requires accurate characterization of population structure, […]

LONDRAVILLE, RL; KINTER, M; JURY, DR; University of Akron; Lerner Research Institute, Cleveland Clinic Foundation; University of Akron: Proteomic Analyses of Zebrafish Liver- Response to High Calorie Diet We investigated the effects of a high-calorie diet on protein expression in zebrafish (Danio rerio). Fish were fed either 3x/day (high calorie) or 1x/3 days (low calorie) […]

BRITT, E.J.; HICKS, J.W.; BENNETT, A.F.; Univ. of California, Irvine; Univ. of California, Irvine; Univ. of California, Irvine: Production efficiency in prey specialist and generalist populations of Thamnophis elegans. The Western Terrestrial Garter snake, T. elegans, exists in two geographically isolated populations in northern California: a coastal population with a specialized diet of slugs and […]

PIERSON, N. S.; FARRAR, R. S.; RODNICK, K. J.; Idaho State University: Plasma calcium and cardiac responsiveness to extracellular calcium between male and female rainbow trout Sex-related differences in cardiac size and function have been well documented in mammals. Male rainbow trout have larger hearts than similar-size female fish and sexual maturation selectively promotes cardiovascular […]

MEYER, E.*; HAAG, A.L.; VON DIPPE, P.; HEDGECOCK, D.E.; MANAHAN, D.T.; University of Southern California, Los Angeles: Physiological Genomics and the Identification of Genes Involved in Differential Growth Rates of Bivalve Larvae Hybrid vigor is a very important process in evolutionary biology. Using genetically controlled crosses of animals and plants, the phenomenon of enhanced growth […]

CORNELIUS, Jamie M; HAHN, Thomas P; Univ. of California, Davis; Univ. of California, Davis: Physiological Correlates of Nomadic Migration in Red Crossbills Locating food in a spatially and temporally variable environment is a problem faced by all animals. One tactic used by highly mobile animals such as birds is to move as food supplies change. […]

STARCK, J.M.; WIMMER, C.; GENSLER, H.; Univ. of Munich, Germany; Univ. of Munich, Germany; Univ. of Munich, Germany: Patterns of Blood flow in Feeding and Fasting Pythons. A Duplex-Ultrasonography Study The post-feeding response of pythons has been characterized frequently. We have quantitatively studied the patterns of blood flow, i.e., blood flow velocity and blood volume […]

BOUCHIE, L.M.*; WATERMAN, J.M.; BENNETT, N.C. ; JACKSON, T.; Univ. of Central Florida; Univ. of Central Florida; Univ. of Pretoria; Univ. of Pretoria: Ovulation in a social ground squirrel The timing of ovulation, whether an animal is a spontaneous or induced ovulator, plays an important role in the understanding of the evolution of reproductive strategies […]

BORRELL, Brendan J.; Univ. of California, Berkeley: Optimality and Allometry of Nectar Foraging in the Orchid Bees Numerous insects fuel their daily activities by consuming floral nectars, and they imbibe these viscous fluids through a slender, tubular proboscis. Whereas the diverse shapes and sizes of their mouthparts represent evolutionary outcomes of historical contingency and ecological […]

HAZARD, L.C.; MILLER, J.M.*; MARTINEZ, J.; SINERVO, B.; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz: Ontogeny of physiological performance of side-blotched lizards (Uta stansburiana) Physiological performance can influence foraging ability, predator avoidance, or reproductive success, and is therefore often measured in adult […]
