两栖动物脑形态大小的进化权衡与生态适应研究进展

The Research Progress of Evolutionary Tradeoff and Ecological Adaptation of Anurans Brain Size

"认知假说"和"能量限制假说"能够解释脑形态大小的进化。在同一类群的不同物种之间,脑形态大小的差异性与环境因素有关,研究环境因素与脑形态大小之间的关系对了解脑各部分的功能进化具有重要的意义。本文对环境因素、性选择、季节性变化、隐蔽色以及其他器官对两栖动物脑形态大小进化的影响进行了综述。此外,提出了在将来研究中应该结合两栖动物生活史特征和行为特征来探讨其脑形态大小的生态适应机制,为预测物种的濒危情况和指导当地生物多样性的保护方面提供科学依据。

The Cognitive Buffer Hypothesis(CBH)and the Expensive Brain Framework(EBF)give a full account of the revolution of brain size.Environmental factors lead to the difference of brain size among the different species of the same group.It is of great importance to study the relationship between environmental factors and brain size.This paper gives a general introduction to the influence of environmental factors,sexual selection,seasonality,crypsis and organ size on the brain size evolution in anurans.Its adaptation mechanism should be explored in combination with its life history and behaviors.It will provide a scientific guidance for predicting the vulnerability to species extinction and protecting the biodiversity of the local.
