In mammals, maternal photoperiodic programming (MPP) provides a means whereby juvenile development can be matched to forthcoming seasonal environmental conditions.
ABSTRACT Hibernation is an extreme state of seasonal energy conservation, reducing metabolic rate to as little 1% the active state. During hibernation season, many species hibernating mammals cycle repeatedly between (aroused) and (torpid) states (T–A cycling), using brown adipose tissue (BAT) drive cyclical rewarming. The regulatory mechanisms controlling this process remain undefined but are presumed involve thermoregulatory centres in hypothalamus. Here, we used golden hamster...
ECR Spotlight is a series of interviews with early-career authors from selection papers published in Journal Experimental Biology and aims to promote not only the diversity researchers (ECRs) working experimental biology but also huge variety animals physiological systems that are essential for ‘comparative’ approach.

Abstract Background Hibernation is a physiological and behavioural adaptation that permits survival during periods of reduced food availability extreme environmental temperatures. This achieved through cycles metabolic depression body temperature (torpor) rewarming (arousal). Rewarming from torpor the activation brown adipose tissue (BAT) associated with rapid increase in ventilation frequency. Here, we studied rate European hamster ( Cricetus cricetus ) by measuring both BAT temperature,...
