摘要

动物生物地理学的形成和变化反映了生物与其环境之间的长期相互作用,包括生理限制、扩散能力、适应进化与板块构造、全球气候变化和景观变化。这对于具有较长地质历史的谱系尤其明显,因此,这引起了有关产生这种模式的相关过程的问题。昆虫,作为最早的飞行动物,具有非凡的能力来扩大它们的范围和栖息地,并避免不利的条件。它们是探索通过适应增强的历史生物地理学的理想选择。在这里,我们采用串珠草蛉作为模型来探索这种模式和可能的过程,特别是考虑到它们明显不同于通常观察到的纬度多样性梯度模式。此外,由于它们良好的化石记录,可以观察到它们的分布随着时间的推移而显著变化。生态位模拟和评价表明,生态位变化和生态位宽度扩展是间歇性地伴随全球气候变化的。然而,不同生态位相关变量在系统发育保守性和进化不稳定性模式下发生变化。通过对翅膀形态差异的评估和飞行空气动力学建模,我们发现了串珠草蛉的历史和古近纪策略的分化,从而揭示了与生态位变化相关的长期路径。我们的研究结果揭示了串珠草蛉在170年的适应进化和传播历史,这是通过生态位转移和飞行适应的动态策略来实现的,作为对不断变化的星球的响应。

Dynamic interplay between niche variation and flight adaptability drove a hundred million years’ dispersion in iconic lacewings
The form and change of animal biogeography reflects the long-term interplay between organisms and their environment, involving physiological limitation, dispersal capability, and adaptive evolution versus plate tectonics, global climatic shifts, and changing landscapes. This is especially manifest for lineages with extended geological histories, which, therefore, evokes questions as to the associated processes producing such patterns. Insects, as the earliest flying animals, have exceptional abilities for expanding their range and habitats and to avoid detrimental conditions. They are ideal for exploring historical biogeography augmented via adaptation. Here, we employ beaded lacewings as a model to explore such patterns and likely processes, particularly given that they differ notably from the commonly observed pattern of a latitudinal diversity gradient. Furthermore, owing to their good fossil record it can be observed that their distributions varied remarkably through time. Ecological niche modeling and evaluation demonstrate their niche variation and niche breadth expansion intermittently accompanying global climate change. However, different niche relevant variables changed under patterns of either phylogenetic conservatism or evolutionary lability. By assessing wing morphological disparity and modeling flight aerodynamics, we uncovered a continuous improvement of flight efficiency through beaded-lacewing history as well as a Paleogene divergence in strategy, which reveals a long-term associated path with the niche variation. Our results unveil the adaptive evolution and dispersal history of beaded lacewings through 170 My, achieved by dynamic strategies in niche shift and flight adaptation as responses to a changing planet.
