Meeting Abstract 68.1  Saturday, Jan. 5  The environmental and physiological factors modulating immunity in an opportunistic breeder SCHULTZ, EM*; HAHN, TP; Univ. of California, Davis emschultz@ucdavis.edu In order to be optimally suited to the current environment, organisms must choose when and how to allocate limited energy resources to the most essential physiological process. This conflict often results […]

Meeting Abstract 68.6  Saturday, Jan. 5  Energy expenditure is independent of dive function in a deep diving vertebrate, the northern elephant seal MEIR, J.U.; University of British Columbia meir@zoology.ubc.ca Although energetics are fundamental to animal ecology, traditional methods of assessing metabolic rate are not both direct and instantaneous. Recently, continuous blood oxygen (O2) measurements were used to […]

Meeting Abstract 68.3  Saturday, Jan. 5  Corticosterone and brood abandonment in a passerine bird OUYANG, JQ*; HAU, M; Princeton Univ; Max Planck Institute for Ornithology jqouyang@gmail.com Hormones regulate decision-making strategies, in particular by translating an individual’s physiological state into decisions on major behavioural and life-history processes, such as reproduction. Corticosterone, a glucocorticoid hormone, has been gaining attention […]

Meeting Abstract 68.2  Saturday, Jan. 5  Comparing the effects of testosterone treatment on onset and continuity of plumage molt between two species of cardueline finch BRAZEAL, KR*; HAHN, TP; UC Davis; UC Davis krbrazeal@ucdavis.edu All birds must replace their feathers each year in order to survive, but species vary in their flexibility of timing the transition from […]

Meeting Abstract 68.7  Saturday, Jan. 5  Are invasive species stressful? LANGKILDE, T*; FREIDENFELDS, N.A.; THAWLEY, C.J.; ROBBINS, T.R.; GRAHAM, S.P.; Pennsylvania State University tll30@psu.edu Invasive species represent a substantial threat to native species worldwide. Previous research has focused on population-level impacts on invasive species; however, the sub-lethal effects of invasive species on wild living vertebrates are relatively […]

Meeting Abstract 68.4  Monday, Jan. 6 08:45  Proportional psychophysics and the evolution of behavior: The broad influence of Weber’s law AKRE, K.L.*; JOHNSEN, S.; Duke University; Duke University karin.akre@gmail.com Animal decision-making guides reproduction, foraging, predator avoidance, navigation, aggression, and every area of behavior. Sensory systems that translate physical stimuli into perceived quantities allow animals to make decisions […]
