ROSTAL, DC; WIBBELS, T; Georgia Southern University; Univ. of Alabama at Birmingham: Temperature-dependent Sex Determination and Embryonic Development of the Gopher Tortoise (Gopherus polyphemus): A Latitudinal Investigation. The gopher tortoise (Gopherus polyphemus) has been demonstrated to possess TSD in laboratory studies. No studies have however attempted to see how these laboratory results can be applied […]

ALEXANDER, J.K.*; TYTELL, E.D.; Harvard University; Harvard University: Synchronization of respiration and locomotion in the bluegill sunfish Lepomis macrochirus To determine if fish synchronize their locomotion and respiration, we filmed bluegill sunfish (Lepomis macrochirus) using high-speed video and calculated the time differences between locomotory and respiratory events. It is well known that many tetrapods, from […]

GERRY, S.P.*; DEAN, M.N.; University of Rhode Island; University of California, Irvine: Symphyseal force transmission in the jaws of Squalus acanthias Complete fusion of the symphysis stiffens and strengthens the jaws to allow large bite forces to be generated. An unfused symphysis is functionally versatile, however, is likely poor at transmitting forces across the jaws. […]

YAO, Meng; ROH , Hyunsuk ; DENVER, Robert J.; Univ of Michigan, Ann Arbor; Univ of Michigan, Ann Arbor; Univ of Michigan, Ann Arbor: Structural and Functional Analysis of Corticotropin-Releasing Factor Genes in Xenopus laevis Corticotropin releasing factor (CRF) plays a central role in the regulation of neuroendocrine, autonomic, immune, and behavioral responses to physical […]

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).
