Meeting Abstract 59.4  Thursday, Jan. 6  Associative Learning and Pattern Discrimination in Lizards LEAL, M; Duke University mleal@duke.edu Sympatric species commonly exhibit courtship displays that differ in design. The evolution of such differences has been proposed to serve as a mechanism to communicate species identity. Interspecific differences in dewlap patterns of lizards have been proposed to play […]

Meeting Abstract 59.2  Thursday, Jan. 6  A test of a model of visual signal efficacy under natural conditions using Anolis GUNDERSON, Alex R.*; LEAL, Manuel; Duke University; Duke University arg12@duke.edu Two variables that can impact the probability that a signal is perceived by an intended receiver are the physical properties of the environment and the sensory physiology […]

Meeting Abstract 58.3  Thursday, Jan. 6  Velocity-dependant energetics hierarchy for trout swimming in vortical flows LIAO, James C.*; TAGUCHI, Masashige; Whitney Lab, U. Florida Gainesville jliao@whitney.ufl.edu Measuring oxygen consumption (MO2) provides a direct and non-invasive way to assess the energetic cost of swimming. We use intermittent flow respirometry to show that there are multiple regions around a […]

Meeting Abstract 58.1  Thursday, Jan. 6  The effects of perch stability on jumping performance and kinematics in green anole lizards (Anolis carolinensis) GILMAN, C.A.*; IRSCHICK, D.J.; University of Massachusetts Amherst cgilman@bio.umass.edu Animals often rely on jumping as a means to evade predators, pursue prey, defend territories, and simply move around their habitats. Anoline lizards are particularly good […]

Meeting Abstract 58.2  Thursday, Jan. 6  Scrub lizard sprinting performance in field and lab ANDERSON, R.A.*; BALDWIN, K.S.; Western Washington Univ.; Monmouth College Roger.Anderson@wwu.edu An understanding of locomotor adaptedness in terrestrial vertebrates presumably is best achieved by a combination of analyses of locomotion 1) on natural substrata in the microhabitats they typically occupy in the field and […]

Meeting Abstract 58.4  Thursday, Jan. 6  Just swim away: the C-start escape response in four species of surfperches (Embiotocidae) from central California PERLMAN, B.M.; Moss Landing Marine Laboratories perlbm0@wfu.edu Surfperches exhibit a C-start escape response to avoid disturbances, such as predators. This fast-start response consists of bending their body into a “C” shape, immediately followed by swinging […]

Meeting Abstract 58.6  Thursday, Jan. 6  Do bluegill ecomorphs differ in steady swimming performance and energy economy? ELLERBY, DJ*; GERRY, SP; Wellesley College dellerby@wellesley.edu Ecomorphs, distinct morphological types associated with particular habitats, have been identified within many fish populations. Phenotypic plasticity in response to a variable environment has long been recognized as a potential factor in the […]

Meeting Abstract 58.5  Thursday, Jan. 6  A Three-Dimensional Approach to Morphological Variation in Bluegill FEILICH, K.L.*; GERRY, S.P.; ELLERBY, D.J.; Wellesley College; Wellesley College; Wellesley College kfeilich@wellesley.edu Bluegill sunfish, Lepomis macrochirus, show intraspecific morphological and behavioral differences dependent on their environment. Previous metrics quantifying morphological variation in this species have measured two-dimensional external variation in the sagittal […]

Meeting Abstract 57.4  Thursday, Jan. 6  Two and Four-legged Locomotion in Capuchin Monkeys: Implications for the Evolution of Human Bipedalism. DEMES, B*; O’NEILL, MC; Stony Brook Univ.; Stony Brook Univ. bdemes@ms.cc.sunysb.edu Capuchin monkeys are known to locomote on both four and two legs in the wild, adopting a bipedal gait when transporting food items and tools. Understanding […]

Meeting Abstract 57.3  Thursday, Jan. 6  The evolution of locomotor capabilities in lizards SCALES, Jeffrey A; University of Hawaii, Manoa jscales@hawaii.edu Locomotor performance is often considered to be intimately linked with fitness in many organisms. However, the locomotor system of most organisms must perform multiple, often contrasting tasks such high speed running and activities requiring high endurance. […]
