GERALD, G. W.*; CLAUSSEN, D. L.; Miami University, Oxford, OH; Miami University, Oxford, OH: Thermal influences on the velocity of neonate brown snakes (Storeria dekayi) during three different modes of locomotion Studies investigating the locomotor performance of neonate animals are scarce. Compared to adults, the enhancement of a neonate�s locomotor performance should be under strong […]

HORNER, A.M.*; JAYNE, B.C.; University of Cincinnati; University of Cincinnati: The effects of viscosity on the axial motor pattern of the lungfish ( Protopterus annectens) during lateral undulatory swimming Individual organisms often must move in different environments. For example, an amphibious animal living in either an estuarine or ephemeral freshwater ecosystem encounters a variety of […]

Cat�lica de Goi�s, Goi�nia, Brazil: The Mechanism of Burrowing in Leposternon microcephalum (Squamata: Amphisbaenia) Amphisbaenians with a dorso-ventrally flattened skulls (�spade� or �shovel-snouted�) have been described as […]

DEUFEL, A. *; BRUCE, S. D.; Minot State University; Minot State University: Burrowing with a Kinetic Snout in a Snake (Elapidae: Aspidelaps scutatus) Few elongate, fossorial vertebrates have been examined for their mechanics of burrowing. Of those that have, all were found to use an akinetic, reinforced skull to push into the soil, powered mostly […]

GARTNER, G.E.A.*; O’REILLY, J.C.; University of Miami, Florida; University of Miami, Florida: Are caeciliid caecilians (Amphibia: Gymnophiona) superior burrowers? Caecilians are limbless, burrowing amphibians that are found throughout most of the humid tropics. Previous studies have concluded that there is a general trend among caecilians towards a more fossorial lifestyle that is reflected in morphological […]

CARTER, Lance C.; CHRISTENSEN, Chad L.; ANDERSON, Curt*; Brigham Young Univ., Idaho; Brigham Young Univ., Idaho; Idaho State University: Visual and olfactory projections to the brainstem and spinal cord of the leopard frog, Rana pipiens Using the leopard frog, Rana pipiens, as a model organism, our lab has been investigating the anatomical basis for sensorimotor […]

KERFOOT, J. R., Jr..; TURINGAN, R. G. ; STOECKLIN, G. ; Florida Institute of Technology; Florida Institute of Technology; Florida Institute of Technology: The effects of hyoid-mandible and opercular-mandiblelinkage disruption on feeding perfomance in the teleost fish, Centropomus undecimalis. The complex array of musculoskeletal linkages in the feeding mechanism of teleost fishes underlies prey capture […]

BICKLEY, Thomas M.*; ANDERSON, Curt; Idaho State University; Idaho State University: Sensory and motor innervation of the tongue in hylid tree frogs This study investigated the anatomical origins and distributions of neurons innervating the tongue musculature of the green tree frog, Hyla cinerea. Recent research on the neural control of feeding behavior in anuran amphibians […]

CROMPTON, A W; LIEBERMAN, D; Harvard University; Harvard University: Motor control of mastication in mammals: Marsupials and Placentals compared Studies on the neuro-muscular control of jaw movements in mammals, until now, have been almost entirely based, with one exception, namely the American opossum, on placental mammals. For this study electromyograms of the major adductor muscles […]

ROSS, C.F.; BADEN, A.L.; GEORGI, J.; SIPLA, J.; WOLFF, M.; University of Chicago; Stony Brook University; Stony Brook University; Stony Brook University; Stony Brook University: Jaw kinematics in two species of primates Jaw kinematics were studied in two vervet monkeys and three eulemurs to evaluate the influence of species, food type and cycle type on […]
