摘要：
In temperate climates mammals might show elevated glucocorticoid secretion in winter to facilitate catabolism. We investigated the influence of season on the concentration of faecal glucocorticoid metabolites (GCMs) in mountain hares throughout the course of 1 year. The results show that mountain hares did not have higher GCM values in winter. Our results suggested that this lagomorph copes with harsh environmental conditions by reducing metabolic rate instead of depleting fat reserves.
