Meeting Abstract 44.5  Monday, Jan. 5  LIZARD BODY FORM EVOLUTION AS ADAPTATIONS FOR OPTIMAL LOCOMOTION IN DIFFERENT HABITATS PIENAAR, J*; SCALES, J. A. ; WIENS, J. J. ; BUTLER, M. A. ; University of Hawaii jasonpienaar@gmail.com We hypothesize that locomotion requirements through a given habitat are a major determinant of body form evolution amongst lizards. To test […]

Meeting Abstract 44.1  Tuesday, Jan. 5  Seasonal energetics of a northern free-ranging mammal in a resource pulse system FLETCHER, Q.E.*; BOUTIN, S.; MCADAM, A.G.; SPEAKMAN, J.R.; HUMPHRIES, M.M.; McGill Univ. quinn.fletcher2@mail.mcgill.ca Throughout the year, all animals face energetic demands resulting from allocation to reproduction, in addition to variation in food availability and climatic conditions. The role played […]

Meeting Abstract 44.4  Tuesday, Jan. 5  Fueling flight with fat: substrate selectivity of avian CPT PRICE, Edwin R.*; GUGLIELMO, Christopher G.; University of Western Ontario; University of Western Ontario eprice3@uwo.ca Carnitine palmitoyl transferase (CPT) catalyzes the conversion of fatty acyl CoA to fatty acyl carnitine which can then be transported across the mitochondrial membrane. This is often […]
