摘要:

摘要:
, the drivers of caching behaviour, and its impacts on individuals, remain poorly understood, particularly for short-term food cachers. Leopards

摘要:
Food-caching birds rely on stored food to survive the winter and spatial memory has been shown to be critical in successful cache recovery. Bot

摘要:
, the peptide hormones ghrelin and leptin elevate and inhibit consumption and food hoarding, respectively. In birds, administration of both ghrelin and leptin inhibit
