Meeting Abstract P1.33  Tuesday, Jan. 4  Differential Effects of Growth Hormone on the Expression of Insulin-like Growth Factors 1 and 2 WALOCK, C.N.*; MARTIN, L.E.; KITTILSON, J.D.; SHERIDAN, M.A.; North Dakota St. Univ, Fargo chad.walock@ndsu.edu The growth of vertebrates is primarily controlled by the growth hormone (GH)-insulin-like growth factor (IGF) system. In mammals, postembryonic growth is mediated […]

Meeting Abstract P1.77  Tuesday, Jan. 4  Development of the Batoid Synarcual CLAESON, Kerin M; Ohio University claeson@ohio.edu Throughout the course of evolution, certain anatomical complexes stand out as significant innovations in the origin and radiation of major vertebrates clades. For Batoidea, the synarcual cartilage is one of those complexes. I examined the ontogeny of the synarcual across […]

Meeting Abstract P1.74  Tuesday, Jan. 4  Development of stress response in fast (Coturnix japonica) versus slow (Callipepla gamelii) growing species. GASTECKI, M. L.*; REED, W. L. ; North Dakota State University; North Dakota State University michelle.gastecki@ndsu.edu Life-history theory predicts that growing animals are constrained in the amount of energy available for systems that promote survival (i.e., stress […]

Meeting Abstract P1.112  Tuesday, Jan. 4  Development of a hydrodynamic sensor for measuring time varying forces during a robotic frog kick in water. CLEMENTE, CJ*; RICHARDS, C; Harvard University; Harvard University clemente@rowland.harvard.edu A fundamental feature of vertebrate muscle is that maximal forces are generated over a limited range of lengths and velocities. This means that muscle dynamics […]

Meeting Abstract P1.52  Tuesday, Jan. 4  Development and evolution of varition in the autopod KEMP, AD*; THORINGTON, JR, RW; JERNVALL, J; Univeristy of Helsinki; Smithsonian (NMNH); Univeristy of Helsinki addisonkemp@gmail.com The development and evolution of variability in the autopod Developmentally associated variability in teeth has previously been linked to evolvability. This study aims to examine a potentially […]

Meeting Abstract P1.56  Tuesday, Jan. 4  Determining the relationship between temperature, somite development, and the genetics of somitogenesis in zebrafish (Danio rerio) HAMILTON, M.A.*; WARD, A.B.; Adelphi University michellehamilton@mail.adelphi.edu Somites, the precursors of the vertebral column, are integral to the formation and function of vertebrae in Danio rerio. Found in early development stages, somites ultimately determine how […]

Meeting Abstract P1.143  Tuesday, Jan. 4  Dental Microwear Analysis as a Predictor of Feeding Types in Predatory Mesozoic Marine Reptiles POYNTER, Jeremy M*; ADAM, Peter J; Northwest Missouri State University; Northwest Missouri State University j.poynter@gmail.com Extinct members of the predatory marine reptile guild constitute a paraphyletic group that includes ichthyosaurs, plesiosaurs, pliosaurs, and mososaurs. These fast swimming […]

Meeting Abstract P1.62  Tuesday, Jan. 4  Deficiency of Tbx5a during zebrafish development results in altered cardiomyocyte morphology. PARRIE, Lindsay E*; CHERNYAVSKAYA, Yelena A; GARRITY, Deborah M; Colorado State University lparrie@mail.colostate.edu Tbx5, a T-box transcription factor, is required for cardiac development. Mutations of Tbx5 lead to Holt-Oram Syndrome (HOS) in humans. As in HOS, mutation of zebrafish tbx5a […]

Meeting Abstract P1.25  Tuesday, Jan. 4  Corals need their vitamin C too: Effect of antioxidants on the bleaching response TWUM, Danielle; NIETO-ROSAS, Ishaira*; SCHWARZ, Jodi; Vassar College; Vassar College; Vassar College datwum@vassar.edu Coral reefs are complex and fragile communities that serve as a source of food and habitat for marine organisms. Most corals form a mutualistic symbiosis […]
