Metabolism and thermoregulation in the tree shrew, Tupaia belangeri
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2012, Vol 8, Issue 2
Abstract
Maximum metabolic rate is a physiological limitation that is an important for animals' survival, reproduction and geographic. Basal metabolic rate (BMR), nonshivering thermogenesis (NST), and maximum metabolic rate (MMR) were measured was in a small mammal species, [i]Tupaia belangeri[/i], which is a unique species of small-bodied mammals in the Oriental realm. Thermal neutral zone (TNZ) was 30 - 35°C and BMR was 1.38±0.09 ml g[sup]-1[/sup] h[sup]-1[/sup]. NST and MMR were 2.64±0.08 ml g[sup]-1[/sup] h[sup]-1[/sup] and 7.14±0.38 ml g[sup]-1[/sup] h[sup]-1[/sup] in summer, respectively. The ecophysiological properties of relatively high body temperature, wide TNZ, low BMR and thermogenic capacity enable this species to adapt to its environment.
