Higher Rates Of Prebreeding Condition Gain Positively Impacts Clutch Size: A Mechanistic Test Of The Condition-Dependent Individual Optimization Model, Holly L. Hennin, Cody J. Dey, Joël Bêty, H. Grant Gilchrist, Pierre Legagneux, Tony D. Williams, Oliver P. Love

Great Lakes Institute for Environmental Research Publications

A combination of timing of and body condition (i.e., mass) at arrival on the breeding grounds interact to influence the optimal combination of the timing of reproduction and clutch size in migratory species. This relationship has been formalized by Rowe et al. in a condition-dependent individual optimization model (American Naturalist, 1994, 143, 689-722), which has been empirically tested and validated in avian species with a capital-based breeding strategy. This model makes a key, but currently untested prediction; that variation in the rate of body condition gain will shift the optimal combination of laying date and clutch size. This prediction is …

Energetic Physiology Mediates Individual Optimization Of Breeding Phenology In A Migratory Arctic Seabird, Holly L. Hennin, Jöel Bêty, Pierre Legagneux, H. Grant Gilchrist, Tony D. Williams, Oliver P. Love Oct 2016

Energetic Physiology Mediates Individual Optimization Of Breeding Phenology In A Migratory Arctic Seabird, Holly L. Hennin, Jöel Bêty, Pierre Legagneux, H. Grant Gilchrist, Tony D. Williams, Oliver P. Love

Integrative Biology Publications

The influence of variation in individual state on key reproductive decisions impacting fitness is well appreciated in evolutionary ecology. Rowe et al. (1994) developed a condition-dependent individual optimization model predicting that three key factors impact the ability of migratory female birds to individually optimize breeding phenology tomaximize fitness in seasonal environments: arrival condition, arrival date, and ability to gain in condition on the breeding grounds. While empirical studies have confirmed that greater arrival body mass and earlier arrival dates result in earlier laying, no study has assessed whether individual variation in energetic management of condition gain effects this key fitness-related …
