DEUFEL, A.; NETT, J.L.*; Minot State University; Minot State University: Strike Kinematics in Death Adders: Convergence with Vipers? Death adders (Acanthophis) are terrestrial elapids who superficially resemble vipers. They are ambush hunters with large, triangular heads, slender necks, and stout bodies. Elapids and vipers differ significantly in cranial musculoskeletal morphology. Differences relating to prey capture […]

TATEM, S. A. *; DAUER, D. M.; Old Dominion University; Old Dominion University: Spatial and Trophic Relationships among Macrobenthic Species of an Intertidal Sand Flat Our research explores the spatial and trophic dynamics of soft-sediment macrobenthic assemblages on a well-sorted intertidal sand flat laden with conspicuous enteropneust fecal mounds and sparsely clustered Spartina alterniflora near […]

DISILVIO, BE; WEBB, JF; Villanova University; Villanova University: Some Observations on the Teeth of Mesopelagic Fishes Scanning electron microscopy revealed variation in the morphology and arrangement of the teeth in representatives of nine genera of mesopelagic fishes belonging to the orders Stomiiformes (Argyropelecus, Cyclothone), Myctophiformes (Protocyctophus, Lampanyctus, Diaphus, Stenobrachius, Notoscopelus), Scorpaeniformes (Sebastolobus) and Beryciformes (Poromitra). […]

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 […]
