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 […]

Gecko tails flip out modulated motor control and variable movement following autotomy
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 […]
Dynamic stability during quadrupedal arboreal locomotion in the Siberian chipmunk (Tamias sibiricus)
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 […]
Digital enhancement three-dimensional locomotor kinematics of two species of padless geckos
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 […]
The role of parental care in mediating a plastic life-history switch point an example from a Neotropical glassfrog
Meeting Abstract 75.3 Friday, Jan. 7 The role of parental care in mediating a plastic life-history switch point: an example from a Neotropical glassfrog DELIA, Jesse; East Carolina University jdelia82@gmail.com In species that modify the environment of their offspring, parental control of embryonic conditions can alleviate environmental heterogeneity and alter direct offspring-environmental interactions that would otherwise favor […]
Synchronous Hatching Mechanisms and Evolution
Meeting Abstract 75.6 Friday, Jan. 7 Synchronous Hatching: Mechanisms and Evolution SPENCER, R-J*; MCGLASHAN, J; COLBERT, P; JANZEN, F; University of Western Sydney, Australia; University of Western Sydney, Australia; Iowa State University; Iowa State University r.spencer@uws.edu.au The timing of birth has enormous implcations for both immediate and future survival. In animals that produce more than one offspring, […]

M.; Boston University, MA; Boston University, MA; Universidad de Costa Rica, San Jose; Boston University, MA tobias.landberg@gmail.com Red-eyed treefrog embryos […]
Does extended incubation affect morphology and feeding ability of larval California grunion, Leuresthes tenuis
Meeting Abstract 75.4 Friday, Jan. 7 Does extended incubation affect morphology and feeding ability of larval California grunion, Leuresthes tenuis? CARRILLO, A.*; ALMASARWEH, F.A.; DICKSON, K.A.; California State University Fullerton; California State University Fullerton; California State University Fullerton An.Carrillo@yahoo.com The California grunion, Leuresthes tenuis, has the ability to extend embryonic incubation beyond hatching competency. Normal incubation occurs […]
Does delayed hatching in the California grunion, Leuresthes tenuis, affect larval development, swimming activity and survival
Meeting Abstract 75.5 Friday, Jan. 7 Does delayed hatching in the California grunion, Leuresthes tenuis, affect larval development, swimming activity and survival? ARYAFAR, H.*; DICKSON, K.A.; California State University Fullerton; California State University Fullerton HelenaAryafar@gmail.com The California grunion spawns terrestrially and is able to extend embryonic incubation in the sand beyond the initial incubation period of 9-14 […]
