摘要

动物的个性是行为生态学迅速发展的一个焦点,越来越多的研究发现,动物的个性在生态过程中发挥着重要作用。这项研究建立在越来越多的文献基础之上,这些文献是关于衰退的爬行动物物种Terrapene carolina carolina(东部箱龟)的,该物种表现出高度一致的个性特征,并可能对适应性产生影响。我们利用这一富有成效的研究系统表明,生态相互作用的空间差异并没有导致种群间平均胆量的差异,但有些种群个体间的变异水平较高。此外,我们还强调了胆量的性别差异,以及人为土地利用变化在塑造卡罗莱纳蝶种群胆量方面的潜在作用。这些发现丰富了有关动物性格的文献,并探讨了种群间性格差异的缺失以及种群内行为多样性水平的潜在重要性等较少被讨论的现象。

Intrapopulation variation in boldness differs while average boldness is similar across populations of a widespread turtle

Intrapopulation variation in boldness differs while average boldness is similar across populations of a widespread turtle

Animal personality is a rapidly growing focus of behavioral ecology and increasingly is found to play a significant role in ecological processes. This study builds upon a growing body of literature on the declining reptile species Terrapene carolina carolina (the eastern box turtle) that shows highly consistent personality traits with probable fitness effects. We used this productive study system to show that spatial variation in ecological interactions has not led to divergence among populations in their average boldness, but that some populations have higher levels of variability among individuals. Furthermore, we highlight sex differences in boldness and a potential role for anthropogenic land use change in shaping boldness of T. c. carolina populations. These findings add to the growing body of literature on animal personality and explore the less commonly discussed phenomena of the absence of among-population variation in personality and the potential importance of levels of behavioral diversity within populations.
