Meeting Abstract 55.2  Thursday, Jan. 6  The population genetic structure of ground snakes (Sonora semiannulata) COX, Christian L*; DAVIS, Alison R; The University of Texas, Arlington; The University of California, Berkeley clcox@uta.edu Population size, gene flow, and genetic diversity affect the persistence of populations through time and space. Organisms with small body size and low vagility may […]

Meeting Abstract 55.1  Thursday, Jan. 6  The association between sex ratio, melanism and numerical abundance in mosquitofish HORTH, Lisa; Old Dominion University lhorth@odu.edu Male mosquitofish have two pigmented genotypes. The common morph is olivaceous gray and the rare morph is melanic (black spotted). Point mutations in genes associated with melanism, and with protein expression differences have been […]

Meeting Abstract 55.5  Thursday, Jan. 6  Recently established populations of Botryllus schlosseri (Ascidiacea) show high diversity at the fusion/histocompatibility locus WANG, V.H.*; COHEN, C.S.; Romberg Tiburon Center for Environmental Studies, Department of Biology, San Francisco State University vhwang@rtc.sfsu.edu Studies of invasive populations are most often conducted with neutral loci, which may not have enough variation to examine […]

Meeting Abstract 55.4  Thursday, Jan. 6  Comparison of genetic structure of the Florida Sand Skink, Plestiodon reynoldsi in homogeneous and heterogeneous scrub on Lake Wales Ridge in central Florida FOX, Alicia M*; SCHREY, Aaron W; MCCOY, Earl D; MUSHINSKY, Henry R; University of South Florida; University of South Florida; University of South Florida; University of South Florida […]

Meeting Abstract 54.5  Thursday, Jan. 6  Intervertebral joint kinematics during the startle response in Striped bass, Morone saxatilis NOWROOZI, B.N.*; BRAINERD, E.L.; Brown University; Brown University bryan_nowroozi@brown.edu The vertebral column provides both stiffness and flexibility to the body to aid in locomotion in a variety of vertebrate taxa. Despite this conserved function, the morphology of vertebrae and […]

Meeting Abstract 54.3  Thursday, Jan. 6  Form-function relationship between ray skeletal architecture and ray locomotion RUSSO, R/S*; BLEMKER, S/S; FISH, F; MOORED, K; BART-SMITH, H; University of Virginia; University of Virginia; West Chester University; University of Virginia; University of Virginia rsr4q@virginia.edu Rays within the myliobatoidae family exhibit compelling differences in their skeletal architecture that are seemingly correlated […]

Meeting Abstract 54.4  Thursday, Jan. 6  Effects of body shape on myoseptal tendon ossification in teleost fishes DANOS, N*; WARD, AB; Harvard University; Adelphi University ndanos@oeb.harvard.edu Fish body muscles are arranged along the vertebral column in three-dimensional W-shaped blocks, called myomeres. Each myomere is separated from its neighbours by a collagenous sheet, the myoseptum, and embedded in […]

Meeting Abstract 54.1  Thursday, Jan. 6  Effect of Funnel Aperture Variation on Jet Dynamics of Squid BARTOL, I.K.; Old Dominion University, Norfolk, VA ibartol@odu.edu Squids employ a dual mode propulsive system involving a pulsed jet and complex fin movements, both of which are capable of producing multiple wake modes. The two most prominent hydrodynamic jet modes observed […]

Meeting Abstract 54.2  Thursday, Jan. 6  Dorsal Fin Muscle Activity During Steady Swimming in Two Shark Species MAIA, Anabela*; WILGA, Cheryl D.; Univ. of Rhode Island; Univ. of Rhode Island amaia@my.uri.edu Elasmobranch dorsal fins have simpler muscoskeletal systems than teleost fishes. This has not deterred elasmobranchs from occupying most available ecological niches. The goal of this study […]

Meeting Abstract 53.4  Thursday, Jan. 6  The role of vision in coordinating forelimb muscle activity patterns during toad landing GILLIS, Gary B*; TIERNEY, Catherine; Mount Holyoke College; Mount Holyoke College ggillis@mtholyoke.edu Unlike many anurans, cane toads (Bufo marinus) are exemplary at landing, using their forelimbs after a hop to balance the body for extended periods as the […]
