尽管在一系列动物分类中经常观察到特定的生理和行为特征之间的相关性，但这些关联的性质已经被证明是不同的。在这里，我们认为这种不一致的一个主要来源是环境应激源的影响，环境应激源似乎能够揭示、掩盖或调节生理和行为特征的协变。这些效应似乎是通过观察到的性状变异的变化和不同表型对应激源的差异敏感性来调节的。考虑到野生动物经常面临一系列生物和非生物应激源，增加对这些影响的了解对于理解一系列生态现象的原因机制和与环境变化相关的应激源的进化反应至关重要。
Although correlations have frequently been observed between specific physiological and behavioural traits across a range of animal taxa, the nature of these associations has been shown to vary. Here we argue that a major source of this inconsistency is the influence of environmental stressors, which seem capable of revealing, masking, or modulating covariation in physiological and behavioural traits. These effects appear to be mediated by changes in the observed variation of traits and differential sensitivity to stressors among phenotypes. Considering that wild animals routinely face a range of biotic and abiotic stressors, increased knowledge of these effects is imperative for understanding the causal mechanisms of a range of ecological phenomena and evolutionary responses to stressors associated with environmental change.
