Meeting Abstract P3.69 Saturday, Jan. 5 Does sex predict the frequency and type of scute anomalies in diamondback terrapins (Malaclemys terrapin terrapin)? PERRY, ML*; BAKER, PJ; Swarthmore College; Swarthmore College margaret.leigh.perry@gmail.com Scute anomalies are irregularities in the scales covering the bones of a turtle�s shell. Previous research has shown that high incubation temperatures increase the frequency of […]

Do snakes possess locomotor adaptations in frequently-used microhabitats Performance and energetic costs of different modes of locomotion in colubrid snakes
Meeting Abstract P3.54 Saturday, Jan. 5 Do snakes possess locomotor adaptations in frequently-used microhabitats? Performance and energetic costs of different modes of locomotion in colubrid snakes GERALD, Gary W.*; CLAUSSEN, Dennis L.; Miami University; Miami University geraldgw@muohio.edu Maximizing locomotor ability in all habitats an animal encounters throughout its normal activity range may not be possible if traits […]
Do Stream Pools Act as Sinks for Passively Transported Larvae
Meeting Abstract P3.116 Saturday, Jan. 5 Do Stream Pools Act as Sinks for Passively Transported Larvae? SCHAMEL, Lindsay B.*; FINGERUT, Jonathan T.; Saint Joseph’s University; Saint Joseph’s University ls413138@sju.edu The non-swimming larvae of the black fly (Simulium tribulatum) are dependent on fluid-mediated dispersal to reach new habitats in response to conspecific competition, predation, and inadequate food supplies. […]
Differential growth and the evolution of novel vertebral morphology lessons from the cypriniform Weberian apparatus
Meeting Abstract P3.20 Saturday, Jan. 5 Differential growth and the evolution of novel vertebral morphology: lessons from the cypriniform Weberian apparatus BIRD, NC*; HERNANDEZ, LP; George Washington University; George Washington University nbird@gwu.edu The Weberian apparatus, a complex assemblage of vertebral elements linking the inner ear to the swimbladder, significantly enhances hearing within Otophysi. We are interested in […]
Diet-induced developmental gut plasticity Implications for the evolution of alternate feeding strategies within and between species
Meeting Abstract P3.15 Saturday, Jan. 5 Diet-induced developmental gut plasticity: Implications for the evolution of alternate feeding strategies within and between species LEDON-RETTIG, C.*; PFENNIG, D.W.; NASCONE-YODER, N.; Univ. North Carolina, Chapel Hill; Univ. North Carolina, Chapel Hill; North Carolina State Univ. ledonret@email.unc.edu Many species exhibit phenotypic plasticity in digestive tract morphology and physiology, and this plasticity […]
Diastolic filling time limits cardiac output in thermally stressed grass shrimp (Palaemonetes pugio) Physiological limits to temperature extremes
Meeting Abstract P3.8 Saturday, Jan. 5 Diastolic filling time limits cardiac output in thermally stressed grass shrimp (Palaemonetes pugio): Physiological limits to temperature extremes REIBER, C.L.; MIKA, T.L.*; University of Nevada Las Vegas; University of Nevada Las Vegas carl.reiber@unlv.edu Metabolic rate increases with increasing temperature in poikilothermic animals, to maintain aerobic metabolism, internal oxygen delivery rates must […]
Developmental temperature affects larval anuran shape trajectories
Meeting Abstract P3.67 Saturday, Jan. 5 Developmental temperature affects larval anuran shape trajectories JORGENSEN, Michael/E.*; SHEIL, Christopher; Ohio University mj207406@ohio.edu Few studies have quantified and described the differences in ontogenetic trajectories of developing amphibians. Here, differences in larval anuran ontogeny are examined after manipulating an abiotic developmental factor��temperature. Developmental series of American Toad (Anaxyrus americanus) larvae were […]
Control of salt gland secretion in two insectivorous lizard species
Meeting Abstract P3.83 Saturday, Jan. 5 Control of salt gland secretion in two insectivorous lizard species HAZARD, L.C.**; LECHUGA, C.; ZILINSKIS, S.; Montclair State University, NJ; Montclair State University, NJ; Montclair State University, NJ hazardl@mail.montclair.edu When dietary salt content is high, some reptile species rely on cranial salt glands to supplement renal ion excretion. The salt glands […]
Compromised weaponry enhances crayfish tailflipping
Meeting Abstract P3.75 Saturday, Jan. 5 Compromised weaponry enhances crayfish tailflipping ESPINOZA, S.Y.*; FAULKES, Z.; The University of Texas-Pan American Beluhua@aol.com As a defense strategy, many crustaceans perform one of two well described stereotyped single fast tailflips (~6 ms in adult crayfish), which are triggered by a neural circuit that includes medial giant interneurons (MG) and lateral […]
Comparative Analysis of the Ontogeny of Color Pattern in two Neotropical cichlid fishes, Thorichthys meeki and Cichlasoma nigrofasciatum
Meeting Abstract P3.65 Saturday, Jan. 5 Comparative Analysis of the Ontogeny of Color Pattern in two Neotropical cichlid fishes, Thorichthys meeki and Cichlasoma nigrofasciatum BEECHING, S.C.*; PIKE, R.E.; Slippery Rock University of Pennsylvania simon.beeching@sru.edu Rapid speciation, complex behavior, and striking color patterns have placed cichlid fishes (Perciformes; Cichlidae) among the most important taxa in the study of […]
