Meeting Abstract 19.4  Thursday, Jan. 3  Genetic connectivity in Sterechinus (Echinodermata: Echinoidea) from South American and Antarctic waters COX, L.N.*; HALANYCH, K.M.; Clemson University; Auburn University lncox@clemson.edu The genus Sterechinus Koehler, 1901 represents the only regular urchins found in Antarctic waters. In particular, S. neumayeri, S. antarcticus, and S. agassizi are morphologically similar species found in the […]

Meeting Abstract 18.4  Thursday, Jan. 3  What�s the point? Undulatory swimming with the tapering tail of the alligator FISH, Frank E*; LAUDER, George V; West Chester Univ.; Harvard Univ. ffish@wcupa.edu Many hydrodynamic models, often used to calculate thrust production and efficiency during undulatory swimming by aquatic animals, assume that the end of the tail has a broad […]

Meeting Abstract 18.2  Thursday, Jan. 3  Optimal stroke patterns for a model jellyfish swimmer with thin, flexible body PENG, Jifeng*; DABIRI, John O; California Institute of Technology; California Institute of Technology jfpeng@caltech.edu In this study, a numerical model is built to simulate swimming of oblate jellyfish (e.g. Aurelia aurita). The model swimmer is a thin, axisymmetric circular […]

Meeting Abstract 18.3  Thursday, Jan. 3  Modeling the kinematic determinants of anuran swimming performance RICHARDS, Christopher T.*; BIEWENER, Andrew A.; Harvard University; Harvard University richards@fas.harvard.edu Swimming anurans generate hydrodynamic thrust by extending their leg joints to produce translational and rotational foot motion. Variation in recruitment of extensor muscles at different joints can greatly alter foot kinematics, potentially […]

Edwards […]

Meeting Abstract 18.1  Thursday, Jan. 3  Comparing the energetics of jellyfish motion: laboratory and field measurements using a Self-Contained Underwater Velocimetry Apparatus (SCUVA) KATIJA, K.*; DABIRI, J.O.; California Inst. of Technology; California Inst. of Technology kakani@caltech.edu We conduct laboratory measurements of the flow fields induced by Aurelia labiata over a range of sizes using the method of […]

Meeting Abstract 18.5  Thursday, Jan. 3  A Hydroelastic Model for the Scaling of Steady Swimming in Cetaceans ENGEL, Virginia L*; MCLELLAN, William; PABST, Ann; FISH, Frank; LONG, John; Vassar College; University of North Carolina Wilmington; University of North Carolina Wilmington; West Chester University; Vassar College viengel@vassar.edu Cetaceans range in length from 1.5 to 30 m, scaling isometrically […]

Meeting Abstract 17.2  Thursday, Jan. 3  Visceral topography in elongate vertebrates WARD, A.B.*; KLEY, N.J.; Adelphi University; Stony Brook University award@adelphi.edu Body elongation has evolved multiple times among vertebrates. In general, this involves modifications to the vertebral column such that there are either more vertebrae or longer vertebrae. Such modifications can occur across the entire vertebral column […]

Meeting Abstract 17.4  Thursday, Jan. 3  The Evolutionary History of the Triggerfishes (Family Balistidae) with a Comparative Study of Fin Morphology and Mechanics DORNBURG, A.*; SANTINI, F.; SORENSON, L.; ALFARO, M.E.; Washington State University, Pullman WA; University of Toronto, Toronto Ontario; Washington State University, Pullman WA dornburgalex@yahoo.com Here we present a novel phylogenetic hypothesis for the triggerfishes […]

Meeting Abstract 17.5  Thursday, Jan. 3  Roost-making behavior and bite force of bats living inside active termite nests SANTANA, Sharlene E.*; DECHMANN, Dina K. N.; DUMONT, Elizabeth R.; UMass Amherst; Leibniz-Institute for Zoo and Wildlife Research; UMass Amherst ssantana@bio.umass.edu Most mammals are polygynous, often living in small groups in which one or a few males mate with […]
