摘要

个体行为的可塑性使动物能够适应不同的情景。然而,个性特征限制了这种灵活性,导致个体间行为的持续差异。尽管在复杂的自然系统中很难测试这一点,但这些个体行为特征有可能会影响群落的相互作用。对于经常对生态系统功能产生强烈影响的大型捕食者来说,这种行为多样性可能尤为重要,并导致个体化的生态系统角色。我们提出了一个量化大型野生食肉动物个体行为可塑性和个性特征的框架,揭示了某些自然行为在多大程度上受这些潜在特征的支配。研究结果将揭示野生动物的先天特征如何扩大到影响群落互动。

Keystone individuals – linking predator traits to community ecology

Individual behavioral plasticity enables animals to adjust to different scenarios. Yet, personality traits limit this flexibility, leading to consistent interindividual differences in behavior. These individual behavioral traits have the potential to govern community interactions, although testing this is difficult in complex natural systems. For large predators who often exert strong effects on ecosystem functioning, this behavioral diversity may be especially important and lead to individualized ecosystem roles. We present a framework for quantifying individual behavioral plasticity and personality traits of large wild predators, revealing the extent to which certain natural behaviors are governed by these latent traits. The outcomes will reveal how the innate characteristics of wildlife can scale up to affect community interactions.

期刊介绍: Trends in Ecology & Evolution (TREE) is a comprehensive journal featuring polished, concise, and readable reviews, opinions, and letters in all areas of ecology and evolutionary science. Catering to researchers, lecturers, teachers, field workers, and students, it serves as a valuable source of information. The journal keeps scientists informed about new developments and ideas across the spectrum of ecology and evolutionary biology, spanning from pure to applied and molecular to global perspectives. In the face of global environmental change, Trends in Ecology & Evolution plays a crucial role in covering all significant issues concerning organisms and their environments, making it a major forum for life scientists.
