Introduction Organisms inhabiting high latitudes confront challenges associated with pronounced seasonality, featuring long and cold winters with limited food resources, contrasted by brief summer seasons. These provide a constrained timeframe for reproductive activities and preparations for the ensuing prolonged and harsh winter.

AbstractBats inhabiting northern latitudes are faced with short reproductive seasons during which they must produce and rear pups before fattening up in time to survive the winter hibernation. Therefore, the timing of parturition has considerable impacts on future fitness prospects for mother and pup; however, little is known about individual variation in breeding phenology and its consequences for postnatal development within bat populations.

1 INTRODUCTION The dilemma of small-birds-in-winter needing to balance high energetic demands with limited foraging opportunities during short winter days is a well-known paradigm in behavioural ecology research (e.g. Bednekoff & Houston, 1994; Brodin, 2007; Brodin et al., 2017; McNamara et al., 1994). A similar but less well-known dilemma is the one small bats face in summer at high latitudes.
