While the evolution of seasonal migration and its association with biogeography have been the subject of numerous studies, its influence on species diversification has rarely been examined. The aim of this study is to explain the atypical latitudinal diversity gradient in shorebirds: did seasonal migration influence diversification and did the gradient evolve from higher in situ diversification or repeated transitions?

鸻鹬类的季节性迁徙和逆纬度多样性梯度的演化

虽然季节性迁徙的演变及其与生物地理学的关联已成为众多研究的主题，但其对物种多样化的影响却很少被研究。本研究的目的是解释鸻鹬鸟的非典型纬度多样性梯度：季节性迁徙是否影响多样化，梯度是否从较高的原地多样化或重复过渡中演变而来？
