青蛙和蟾蜍（两栖纲：无尾目）表现出不同的生态和行为，这通常与其他脊椎动物的视觉能力有关。此外，无尾目动物的相对眼睛大小差异很大，这在以前并没有与这一群体的生态因素联系起来。我们测量了220种无尾动物在眼睛大小和角膜大小上的相对投资，这些无尾动物代表了目前已知的55个家族，并测试了它们是否与六种自然历史特征相关，这些特征被假设与眼睛大小的进化有关。眼大小与生境显著相关，在穴居、亚穴居和水生物种中，眼投资显著减少。相对眼睛大小也与交配栖息地和活动模式有关。与其他脊椎动物相比，无脊椎动物的眼睛相对于它们的身体大小来说相对较大，这表明视力可能非常重要。我们的研究揭示了生态和行为可能在无脊椎动物视觉系统的进化中发挥的作用，并强调了博物馆标本的有用性，以及广泛的分类抽样对解释宏观生态模式的重要性。
Frogs and toads (Amphibia: Anura) display diverse ecologies and behaviours, which are often correlated with visual capacity in other vertebrates. Additionally, anurans exhibit a broad range of relative eye sizes, which have not previously been linked to ecological factors in this group. We measured relative investment in eye size and corneal size for 220 species of anurans representing all 55 currently recognized families and tested whether they were correlated with six natural history traits hypothesized to be associated with the evolution of eye size. Anuran eye size was significantly correlated with habitat, with notable decreases in eye investment among fossorial, subfossorial and aquatic species. Relative eye size was also associated with mating habitat and activity pattern. Compared to other vertebrates, anurans have relatively large eyes for their body size, indicating that vision is probably of high importance. Our study reveals the role that ecology and behaviour may have played in the evolution of anuran visual systems and highlights the usefulness of museum specimens, and importance of broad taxonomic sampling, for interpreting macroecological patterns.
