Mid-winter temperatures, not Spring temperatures, predict breeding phenology and fecundity in the European starling
Meeting Abstract 45.1 Saturday, Jan. 5 Mid-winter temperatures, not Spring temperatures, predict breeding phenology and fecundity in the European starling WILLIAMS, T.D.; Simon Fraser Uni. tdwillia@sfu.ca The current working model for control of timing of breeding suggests that day length provides reliable ‘initial predictive information’ for general seasonal breeding but that ‘supplemental factors’, especially ambient temperature (Ta), […]
Fitness consequences of individual variation in stress hormone levels why repeatability and plasticity of physiological traits matter
Meeting Abstract 45.6 Saturday, Jan. 5 Fitness consequences of individual variation in stress hormone levels: why repeatability and plasticity of physiological traits matter MADLIGER, C.L.*; LOVE, O.P.; University of Windsor, Ontario; University of Windsor, Ontario madlige@uwindsor.ca Physiological measures can provide insight into how organisms respond mechanistically to changes in their environment. Baseline stress hormones (glucocorticoids – GCs) […]
DYNAMICS OF FAT AND LEAN MASS IN REFUELLING MIGRANT PASSERINES MEASURED USING QUANTITATIVE MAGNETIC RESONANCE
Meeting Abstract 45.3 Saturday, Jan. 5 DYNAMICS OF FAT AND LEAN MASS IN REFUELLING MIGRANT PASSERINES MEASURED USING QUANTITATIVE MAGNETIC RESONANCE KENNEDY, L.V.*; GUGLIELMO, C.G.; University of Western Ontario lkenne2@uwo.ca Although fat deposition during stopover in migrating passerine birds has been extensively studied, changes in lean mass during refuelling are not well understood. I used quantitative magnetic […]
Corticosterone mediated costs of reproduction facilitate a tradeoff between current and future reproduction
Meeting Abstract 45.2 Saturday, Jan. 5 Corticosterone mediated costs of reproduction facilitate a tradeoff between current and future reproduction. CROSSIN, GT*; PHILLIPS, RA; LATTIN, CR; ROMERO, LM; WILLIAMS, TD; Dalhousie University; British Antarctic Survey; Tufts University; Tufts University; Simon Fraser University gtc@dal.ca Life-history theory predicts costs of reproduction.

The allometry of tongue-flicking mechanics in colubrid snakes
Meeting Abstract 45.4 Sunday, Jan. 5 11:00 The allometry of tongue-flicking mechanics in colubrid snakes RYERSON, WG*; SCHWENK, K; University of Connecticut william.ryerson@uconn.edu Oscillatory tongue-flicking in snakes enhances the rate of diffusion of odorant molecules onto the mucus covering the tongue, which is then delivered to the vomeronasal organ. The multiple oscillations of the tongue generate a […]
