Basic design natural and experimentally-induced variation in autumn hoard size winter behaviour and metabolism spring behaviour and metabolism reproductive success

a) Metabolic requirements of foraging in a cold environment reduced hoard size increases cold exposure increases thermogenic requirements increased Summit MR – FMR – RMR in winter

b) Links between RMR, FMR, and SMR repeated winter and reproductive metabolic measurements quantified and experimentally manipulated food availability

d) Metabolic consequences of early reproduction timing of parturition important natural (and experimentally induced?) variation in parturition date predict early breeders have higher FMR (and RMR?), lower production efficiency, but higher RS
