摘要

物种特有的能源利用模式的知识对于理解生命史的进化以及确定物种如何应对环境条件的变化是重要的。我们测量了59只东箱龟(质量范围为106 - 510 g)的标准代谢率(SMRs)，并确定了体重和体温(20°C vs. 30°C)的差异如何影响SMRs。20°C和30°C时，标准代谢率显著受体重影响，30°C时SMR显著较高(Q10 = 3.04)。个体间SMR差异显著，20℃时代谢水平较高的个体在30℃时代谢水平也趋于较高。

Influences on Standard Metabolism in Eastern Box Turtles (Terrapene carolina)

Abstract Knowledge of species-specific patterns of energy use is important for understanding the evolution of life histories as well as for determining how species might respond to alterations in environmental conditions. We measured standard metabolic rates (SMRs) in 59 Eastern Box Turtles (mass range = 106−510 g) and determined how differences in body mass and body temperature (20°C vs. 30°C) influenced SMRs. Rates of standard metabolism were significantly influenced by body mass at body temperatures of 20°C and 30°C and SMR was significantly higher at 30°C (Q10 = 3.04). There was significant among-individual variation in SMR and individuals with higher metabolism at 20°C also tended to have higher metabolism at 30°C.

期刊介绍： Chelonian Conservation and Biology is a biannual peer-reviewed journal of cosmopolitan and broad-based coverage of all aspects of conservation and biology of all chelonians, including freshwater turtles, marine turtles, and tortoises. Manuscripts may cover any aspects of turtle and tortoise research, with a preference for conservation or biology. Manuscripts dealing with conservation biology, systematic relationships, chelonian diversity, geographic distribution, natural history, ecology, reproduction, morphology and natural variation, population status, husbandry, community conservation initiatives, and human exploitation or conservation management issues are of special interest.
