Head-body length variation in the mole-shrew (Anourosorex squamipes) in relation to annual temperature and elevation

Temperature change may affect physiology, distribution, morphology and adaptation of animals. Using individuals captured in Nanchong and Laojunshan Nature Reserve of Sichuan province in western China, we tested head-body length variation in the mole-shrew (Anourosorex squamipes) in relation to annual temperature and elevation. Our results indicate that head-body length of both males and females decreases with decreasing ambient temperature along an altitudinal gradient. Likewise, there is significant monthly variation in head-body length, with individuals in warmer months being larger than that colder ones. The seasonal variation in head-body length suggests the higher predator risk and lower food availability in cold months.
