SPAGNA, J.C.*; GOLDMAN, D.I.; FULL, R.J.; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley: Contribution of a Distributed Foot to Running Performance in Arthropods Arthropods are capable of stable running at high speeds over irregular surfaces. Foot-substrate interactions must contribute to this ability, yet foot placement during dynamic movement remains largely […]

HYDE, Martha L; West Texas A&M University: Bipedal Locomotion In Two Species of Kangaroo Mice in the Laboratory Previous work on Great Basin Desert kangaroo mice (9-13 g), Microdipodops pallidus and M. megacephalus have been shown to move bipedally as their nearest relatives, the kangaroo rats. Neither species of kangaroo mouse show a sustained bipedal […]

TAYLOR, J. R. *; WHITTAMORE, J. M. ; WILSON, R. W. ; GROSELL, M. ; RSMAS, University of Miami; Exeter University, UK; Exeter University, UK; RSMAS, University of Miami: Postprandial acid-base balance in freshwater and seawater-acclimated European flounder Intestinal HCO3– secretion and resultant carbonate precipitation are important in the hydromineral balance of all fishes sampled […]

GROSELL, M.*; TAYLOR, J.R.; GENTZ, J.; University of Miami; University of Miami; University of Miami: Marine teleost osmoregulation involves highly acidic and hyperosmotic fluid absorption by the intestine In marine teleost fish, continuous diffusive water loss is compensated by seawater ingestion. Imbibed seawater is desalinized by the esophagus resulting in roughly iso-osmotic intestinal fluids allowing […]

Meeting Abstract 7.1  Jan. 4  The evolution and emergence of food-webs in fluctuating environments: diversity begets stability, or vice versa? PAWAR, S.; University of Texas at Austin samraat@mail.utexas.edu All natural food-webs are assembled and persist in environments that exert perturbations in energy input as well as living conditions. In this study, we focus on the effects of […]

Meeting Abstract 7.6  Jan. 4  Relationships Between Recruitment and Adult Distribution Among Pseudopterogorgia spp.on the Little Bahama Bank LASKER, HR*; JAMISON, JL; University at Buffalo; University at Buffalo hlasker@buffalo.edu Recruitment of the octocoral Pseudopterogorgia elisabethae was monitored twice a year from May 2004 through June 2006 at 6 sites spanning 60 km along the southern edge of […]

Meeting Abstract 7.2  Jan. 4  Quantifying the resource dynamics of a lizard community: Coupling abiotic drivers and ecosystem productivity to reproduction in lizards WARNE, R.W.*; PERSHALL, A.D.; WOLF, B.O.; University of New Mexico rwarne@unm.edu Desert animals must integrate unpredictable and often ephemeral pulses of resources, yet how these animals allocate limited resources to survival and reproduction in […]
