不同动物的大脑大小和身体大小有很大的不同，但这种变化的生态后果仍然知之甚少。看似合理的是，大脑越大，行为的灵活性就越强，应对新挑战的能力也就越强。与这一假设一致，成功的入侵鸟类和哺乳动物在转移到一个新的区域后蓬勃发展，往往比不成功的入侵者拥有更大的大脑。我们在外温陆生脊椎动物中发现了同样的模式。在被报道成功入侵的两栖动物和爬行动物物种中，大脑大小相对于身体大小，与转移到新地点后未能蓬勃发展的物种相比要大得多。在七个全球生物地理领域中，有六个发现了这种模式；澳大拉西亚是个例外(在那里，相对较大的大脑不利于入侵成功)。在相对脑大小较大的两栖和爬行动物家族中，建立的成功率也更高。未来的研究可能会有益地探索入侵成功是否与大脑特定部分的扩大(正如前脑在促进行为灵活性方面的功能角色所预测的那样)或与整体大小的增加(表明入侵成功是由增强的感知和运动技能以及认知能力促进的)存在差异。
Brain size relative to body size varies considerably among animals, but the ecological consequences of that variation remain poorly understood. Plausibly, larger brains confer increased behavioural flexibility, and an ability to respond to novel challenges. In keeping with that hypothesis, successful invasive species of birds and mammals that flourish after translocation to a new area tend to have larger brains than do unsuccessful invaders. We found the same pattern in ectothermic terrestrial vertebrates. Brain size relative to body size was larger in species of amphibians and reptiles reported to be successful invaders, compared to species that failed to thrive after translocation to new sites. This pattern was found in six of seven global biogeographic realms; the exception (where relatively larger brains did not facilitate invasion success) was Australasia. Establishment success was also higher in amphibian and reptile families with larger relative brain sizes. Future work could usefully explore whether invasion success is differentially associated with enlargement of specific parts of the brain (as predicted by the functional role of the forebrain in promoting behavioural flexibility), or with a general size increase (suggesting that invasion success is facilitated by enhanced perceptual and motor skills, as well as cognitive ability).
