Abstract

How do varying environmental light conditions influence the evolution of avian visual systems? Fröhlich et al. (2024) demonstrate that nocturnal birds evolved broader corneas and slightly longer axial lengths than their diurnal counterparts, increasing light capture efficiency. Nocturnal species also tended to maintain or reduce the size of brain regions responsible for vision, i.e., the optic tectum and the visual wulst. These results highlight adaptive trends in nocturnal species, where evolutionary improvement in low-light performance of eyes may be accompanied by compromised brain function.

摘要:环境光线条件如何影响鸟类视觉系统的进化。
不同的环境光条件如何影响鸟类视觉系统的进化?Fröhlich等人(2024年)证明,夜行鸟类的角膜比日行鸟类更宽,轴长稍长,从而提高了捕光效率。夜行性物种还倾向于保持或缩小负责视觉的脑区(即视神经乳头和视觉鞘)的大小。这些结果突显了夜行性物种的适应趋势,即眼睛弱光性能的进化改善可能伴随着大脑功能的损害。
