Meeting Abstract 90.3  Sunday, Jan. 6  Behavioral variation among tadpole populations: ecological causes and consequences CARLSON, BE*; LANGKILDE, T; The Pennsylvania State University; The Pennsylvania State University bec169@psu.edu Theory predicts that intraspecific trait variation can have important ecological impacts, yet we have a poor understanding of the causes and consequences of trait variation in natural systems. Local […]

Meeting Abstract 90.1  Sunday, Jan. 6  Anthropogenic stressors and the evolutionary potential of amphibian populations WELCH, A.M.; College of Charleston, SC welcha@cofc.edu Virtually all habitats on Earth have been affected by human activities. Understanding and mitigating the ecological consequences of anthropogenic habitat modification require addressing how multiple stressors interact to affect the long-term viability of populations. In […]

Meeting Abstract 89.6  Sunday, Jan. 6  Effects of limb autotomy on locomotor performance of ghost crabs PFEIFFENBERGER, JA*; HSIEH, ST; Temple University; Temple University jpfeiffe@temple.edu Autotomy, or limb loss, is a mechanism frequently used in response to aggressive inter- and intra-specific interactions, despite the possibility of negatively impacting fitness by hampering an animal’s ability to run, walk, […]

Meeting Abstract 89.2  Sunday, Jan. 6  Dynamics of high speed locomotion and hunting in free ranging cheetah WILSON, AM*; ROSKILLY, K; LOWE, J; HUDSON, P; GOLABEK, K; MCNUTT, J; RVC, London; RVC, London; RVC, London; RVC, London; BPCT, Botswana; BPCT, Botswana awilson@rvc.ac.uk Studies of maximum performance are limited by subject motivation and attempts by ourselves and others […]

Meeting Abstract 89.4  Sunday, Jan. 6  Assessing the evidence for the evolution of asymmetrical gaits in Crocodylomorpha HUTCHINSON, JR; The Royal Veterinary College, Structure and Motion Laboratory jrhutch@rvc.ac.uk Some Crocodylia use asymmetrical gaits, including bounding and galloping, at near-maximal speeds. This ability is commonly assumed to have evolved in stem Crocodylomorpha, related to changes in limb/axial morphology. […]

Meeting Abstract 88.2  Sunday, Jan. 6  Regional pressure changes in the digital cushion under vertical load in elephants and horses. WARNER, S E*; HENRY, V; HUTCHINSON, J R; Royal Veterinary College; Royal Veterinary College; Royal Veterinary College swarner@rvc.ac.uk It is difficult to determine how externally applied locomotor loads affect internal foot mechanics, however the digital cushion (DC) […]
