摘要

如果动物的生态位在一个栖息地内有很大的重叠,它们就会为争夺一些有限的可用资源而进入种内和/或种间竞争。我们假设,运动能力的差异可能是决定哪一个个体将获得资源的关键因素,尤其是在敏捷性有限的动物中,比如乌龟。为了验证这一假设,我们测试了两种同域的海龟种群:圆尾龟和河尾龟的自我矫正能力和从类似植被的绳子上释放的能力。所有个体都能迅速完成测试(≤103 s)。当被翻倒在甲壳上时,圆轮蝶的检查时间更短,翻倒时间也更短,在自扶正方面略有优势。另一方面,这两个物种从绑在它们板前面的绳子上释放的效率是一样的。种间形态差异表明,肌肉力量可能是合鳖种间竞争关系的一个很好的预测指标。

Differences in locomotor performances between two sympatric species of freshwater turtles

Animals whose ecological niches largely overlap within a habitat can get into intra-specific and/or inter-specific competition for some of the limited resources available. We hypothesise that differences in locomotor abilities might be a key component deciding which individual will gain the resource, especially in animals with limited agility, such as turtles. To address this hypothesis, we tested self-righting ability and releasing from a vegetation alike rope in two sympatric populations of turtles: Emys orbicularis and Mauremys rivulata. All individuals managed to complete the tests promptly (≤ 103 s). When overturned on their carapace, E. orbicularis had shorter inspecting time, as well as overturning time, indicating slight advantage in self-righting. On the other hand, both species were equally efficient to release from a rope attached to the front of their plastron. The inter-specific morphological differences indicate that muscular strength might be a good predictor of competitive relations among syntopic turtle species.

期刊介绍: acta ethologica publishes empirical and theoretical research papers, short communications, commentaries, reviews and book reviews as well as methods papers in the field of ethology and related disciplines, with a strong concentration on the behavior biology of humans and other animals. The journal places special emphasis on studies integrating proximate (mechanisms, development) and ultimate (function, evolution) levels in the analysis of behavior. Aspects of particular interest include: adaptive plasticity of behavior, inter-individual and geographic variations in behavior, mechanisms underlying behavior, evolutionary processes and functions of behavior, and many other topics. acta ethologica is an official journal of ISPA, CRL and the Portuguese Ethological Society (SPE)
