KRAUS, Naomie J.; O’NEILL, Matthew W.; GIBB, Alice C.; Saint Norbert College; Northern Arizona University; Northern Arizona University: Sexual Dimorphism in the Feeding Kinematics of Betta splendens Prey capture of the aquatic fish, Betta splendens, involves both ram (swimming over the prey) and suction (sucking in the prey), and is similar to the behavior of […]

GILLEM, A.D.*; FINKLER, M.S.; Indiana Univ. Kokomo: Sex-related differences in stored energy reserves in spring-breeding spotted salamanders (Ambystoma maculatum). The energetic cost of reproduction for female mole salamanders may be considerably higher for female mole salamanders than for males, not only because of a difference in the amount of energy invested in the gametes but […]

FRASER, E.J.; RENN, S.C.P.; HOFMANN, H.A.; Harvard University, Bauer Center for Genomics Research; Harvard University, Bauer Center for Genomics Research; Harvard University, Bauer Center for Genomics Research: Sex, Sex-roles, and Dominance: A Functional Genomics Approach How do environment and genome interact to create a phenotype? We address this question by profiling gene expression in the […]

NAKAYA, F.; SAITO, Y.; MOTOKAWA, T.; Tokyo Institute of Technology; Univ. of Tsukuba; Tokyo Institute of Technology: Scaling analysis of physiological time of the colonial ascidian Botrylloides violaceus The physiological time, such as the duration of cardiac cycle and respiratory cycle, lengthens in proportion to the 0.25 power of the body weight in homoeothermic animals. […]

ROTH, E.B.*; SECOR, S.M.; University of Alabama, Tuscaloosa; University of Alabama, Tuscaloosa: Proximate mechanisms regulating intestinal performance for the Burmese python, Python molurus Burmese pythons (Python molurus) widely regulate intestinal performance with each meal. Within 24 hours after feeding, intestinal mass doubles as nutrient transport rates increase by 5 to 20-fold. Elevated intestinal performance is […]

DAVIS, E.C.; University of Kansas, Lawrence: Predicting potential distributions of invasive land snails via ecological niche modeling I will use ecological niche modeling to predict the potential distribution of two invasive snails: the giant African land snail, Achatina fulica, and the rosy wolf snail, Euglandina rosea. Each species� ecological niche will be modeled based upon […]

MCCOY, A.M.; Harvard University: Predicting Biological Invasions: Using Microbes for Highly Specific Predictive Ability Despite recognition of the potential ecological consequences of biological invasions, factors that determine when a particular invasive will be successful remain largely unknown. Many species in the marine environment rely on specific interactions with microbes for a variety of processes including […]

GONZALEZ, V; PEPINO, N; VALERO, S; BOHONAK, A; SIMOVICH, M; U. San Diego; U. San Diego; San Diego State Univ.; San Diego State Univ.; U. San Diego: Polymorphic microsatellite loci for threatened anostracan and related species. Extensive habitat loss in Southern California has resulted in severe decreases in population numbers and possibly declines in genetic […]

MCMULLIN, E.R.; MARSH, A.G.; University of Delaware, Lewes, DE: Poecilogony in the polychaete Streblospio benedictii: incipient speciation or maintained polymorphism? Most benthic marine invertebrate species exhibit only a single developmental mode. Poecilogony, or the occurrence of multiple developmental modes within a species, is very rare, and molecular genetic studies often reveal suspected cases to be […]

CERASALE, D.J.; GUGLIELMO, C.G.; University of Montana; University of Montana: Plasma phospholipid levels and triglyceride:phospholipid ratio as indicators of mass change and diet lipid quality in wild birds Plasma metabolite profiling has received recent attention as a means to assess body mass changes in migratory birds. Prior studies have focused on triglycerides as the main […]
