Intra-specific variation in the metabolic rate of the red squirrel (Tamiasciurus hudsonicus) across western Canada
Meeting Abstract 54.2 Tuesday, Jan. 6 Intra-specific variation in the metabolic rate of the red squirrel (Tamiasciurus hudsonicus) across western Canada BEN-EZRA, E.*; HUMPHRIES, M.M; McGill University; McGill University elad.ben-ezra@mail.mcgill.ca Metabolic rate is a fundamental trait that determines the amount of energy an organism can process and allocate to growth, maintenance, and reproduction. While metabolic rate is […]

FM, not AM Gas exchange during rest and activity in non-flying insects
Meeting Abstract 54.11 Tuesday, Jan. 6 FM, not AM: Gas exchange during rest and activity in non-flying insects LIGHTON, JRB; Univ. of Nevada, Las Vegas lighton@sablesys.com Using the xeric tenebrionid beetle Cryptoglossa verrucosa as a model animal, and using a very fast-responding flow-through respirometry system, I show that the kinetics of gas exchange during activity are practically […]
