Meeting Abstract 75.6  Wednesday, Jan. 6   Metabolic energy cost of locomotion over uneven terrain in the common pheasant (Phasianus colchicus). DALEY, MA*; FISHER, RL; GILES, T; WARNER, S; Royal Veterinary College mdaley@rvc.ac.uk It has been proposed that a trade-off exists between economy and stability of legged locomotion. However, it is unclear whether this is generally true, […]

Meeting Abstract 75.4  Wednesday, Jan. 6  Linking characteristics of stance and swing phase muscles with ecology, morphology and locomotor performance in the lizard, Sceloporus woodi KORCHARI, P.G.*; HIGHAM, T.E.; MCBRAYER, L.D.; Clemson University; Clemson University; Georgia Southern University pkorcha@g.clemson.edu A question that has intrigued scientists for quite some time is how muscle physiology relates to locomotor performance […]

Meeting Abstract 75.1  Wednesday, Jan. 6  Kinematics of the Forefoot in Minipigs (Artiodactyla: Suidae) CLIFFORD, A B; Brown University, Providence RI andrew_clifford@brown.edu Unguligrade foot posture is one where the bones of the foot are elevated from the locomotor substrate, except for the hoofed distal phalanx. Most unguligrade animals (horses and artiodactyls) posses foot joints that are very […]

Meeting Abstract 75.3  Wednesday, Jan. 6  Gecko tails flip out: modulated motor control and variable movement following autotomy HIGHAM, T.E.*; RUSSELL, A.P.; Clemson University; University of Calgary thigham@clemson.edu Many lizards are notable for their ability to self-amputate their tail during an encounter with a predator. The autotomized tail subsequently moves without control from higher centers and serves […]

Meeting Abstract 75.5  Wednesday, Jan. 6  Dynamic stability during quadrupedal arboreal locomotion in the Siberian chipmunk (Tamias sibiricus) LAMMERS, A.R.*; ZURCHER, U.; Cleveland State Univ., Ohio; Cleveland State Univ., Ohio a.Lammers13@csuohio.edu Locomotion on narrow tree branches, twigs, and foliage presents many challenges to maintaining stability during locomotion. We hypothesize that the movement of an arboreal animal plays […]

Meeting Abstract 75.2  Wednesday, Jan. 6  Digital enhancement: three-dimensional locomotor kinematics of two species of padless geckos FULLER, P.O.*; HIGHAM, T.E.; CLARK, A.J.; Clemson University; Clemson University; Clemson University pfuller@clemson.edu Locomotion of pad-bearing species of geckos has garnered considerable interest from researchers. However, many groups of geckos include species that lack toe pads, and thus lack adhesive […]

Meeting Abstract 74.2  Wednesday, Jan. 6  The effects of stress hormones on infection by a fungal pathogen, Batrachochytrium dendrobatidis, in larval amphibians SEARLE, CL*; BELDEN, LK; BLAUSTEIN , AR; Oregon State University; Virginia Tech; Oregon State University searlec@onid.orst.edu Pathogens are important components of ecological communities and can have large influences on species population dynamics. The fungal pathogen, […]

Meeting Abstract 74.4  Wednesday, Jan. 6  The effects of excessive dietary mercury on thyroid-mediated processes and fitness- related traits in wood frog tadpoles WADA, H*; BERGERON, CM; MCNABB, FMA; TODD, BD; HOPKINS, WA; Virginia Tech hwada@uwo.ca Mercury (Hg) is a neurotoxicant known to cause developmental and behavioral abnormalities in vertebrates. Increasing evidence suggests that Hg can also […]

Meeting Abstract 74.1  Wednesday, Jan. 6  Reproductive disruption of fishes by endocrine-active wastewater effluent BOLDEN, A.M.*; VAJDA, A.M.; BARBER, L.B.; SCHOENFUSS, H; NORRIS, D.O.; University of Colorado, Boulder; University of Colorado, Denver; U.S. Geological Survey; St. Cloud St. University; University of Colorado, Boulder alan.vajda@ucdenver.edu We investigated the impact of a wastewater treatment plant (WWTP) effluent on fish […]

Meeting Abstract 74.3  Wednesday, Jan. 6  Effects of nutritional stress during early development on sexual maturation and life expectancy in long-lived seabirds YOUNG, R.C.*; HAUSSMANN, M.F.; BARGER, C.P.; KITAYSKY, A.S.; University of Alaska Fairbanks, AK; Bucknell University, Lewisburg, PA; University of Alaska Fairbanks, AK; University of Alaska Fairbanks, AK rebecca.young@alumni.iu.edu Nutritional stress during juvenile development is known […]
