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 59.6  Friday, Jan. 6  Vertical jumping among mdm mouse genotypes TAYLOR, KR*; PACE, CM; MORTIMER, SA; NISHIKAWA, KC; Northern Arizona University; Northern Arizona University; Northern Arizona University; Northern Arizona University kt375@nau.edu Jumping is a ballistic locomotor behavior that can help elucidate how muscles work. During jumping, elastic components in the limbs store and recover energy […]

Meeting Abstract 59.3  Friday, Jan. 6  The Effects of Substrate Compliance on Jump Performance in the Cuban Tree Frog (Osteopilus septentrionalis). ASTLEY, H.C.*; HARUTA, A.; ROBERTS, T.J>; Brown University; Brown University; Brown University henry_astley@brown.edu Animals locomoting in arboreal habitats face a variety of challenges, including moving on compliant substrates such as terminal branches. Compliant substrates yield when […]

Meeting Abstract 59.2  Friday, Jan. 6  Pre-landing muscle tuning in the forearm and shoulder of Bufo marinus MACESIC, L.J.*; GILLIS, G.B.; Mount Holyoke College, South Hadley, MA; Mount Holyoke College, South Hadley, MA lmacesic@mtholyoke.edu In contrast to a typical frog, which often lands on its belly after a hop, the cane toad (Bufo marinus) is exemplary at […]

Meeting Abstract 59.1  Friday, Jan. 6   Muscle properties are tuned to mechanical function: lessons from hopping toads AZIZI, E; Univ. of California, Irvine eazizi@uci.edu Variation in the basic properties of muscles has likely been shaped by the mechanical tasks muscles perform. However, most muscles cannot be easily fit into a functional category and often perform a […]

Meeting Abstract 59.5  Friday, Jan. 6  Jump racing: do horses slow down due to a force limit? SELF, ZT*; SPENCE, AJ; WILSON, AM; The Royal Veterinary College; The Royal Veterinary College; The Royal Veterinary College zself@rvc.ac.uk Running animals face the challenge of using limb force to support body weight over the time in which their feet are […]

Meeting Abstract 59.4  Friday, Jan. 6  Extrinsic loading in Cuban tree frog jumping ABBOTT, EM*; AZIZI, M; ROBERTS, TJ; Univ. of California, Irvine; Univ. of California, Irvine; Brown University emily.m.abbott@gmail.com It is common for locomoting animals to bear additional loads. It may occur naturally, as with gravidity or large feeding events, or artificially, such as with any […]

Meeting Abstract 59.5  Saturday, Jan. 5  Transgenerational Effects of Parental Hypoxia on Vertebrate and Invertebrate Larvae BURGGREN, W. W.; University of North Texas burggren@unt.edu Non-genetic transgenerational modifications of offspring phenotype are increasingly evident in physiological studies. Indeed, this phenomenon is emerging as a potential source of variation in comparative physiology. Here we focus on non-genetic transgenerational transfer […]

Meeting Abstract 59.3  Saturday, Jan. 5  The delineation of the fourth walking leg segment is temporally linked to posterior segmentation in the mite Archegozetes longisetosus (Acari: Oribatida, Trhypochthoniidae) BARNETT, AA*; THOMAS, RH; Southern Illinois University; Southern Illinois University abarnett@siu.edu Acari (mites and ticks) lack external segmentation, with the only indication of segmentation being the appendages of the […]

Meeting Abstract 59.4  Saturday, Jan. 5  The Genome of the Ctenophore, Mnemiopsis leidyi: Insights into the Genetics of Innovation and the Evolution of Multicellularity RYAN, J.F.; PANG, K.; SCHNITZLER, C.E.; KOCH, B.J.; NGUYEN, A.-D.; MORELAND, R.T.; MULLIKIN, J.C.; WOLFSBERG, T.G.; MARTINDALE, M.Q.; BAXEVANIS, A.D.*; NHGRI/NIH and Sars Intl.
