Abstract

How does sexual selection impact introgression dynamics across a hybrid zone? Long et al. (2024) used historical (1989-1994) and contemporary (2017-2020) samples to quantify the stability of a Panamanian hybrid zone between golden-collared manakins (Manacus vitellinus) and white-collared manakins (M. candei). Their analyses revealed a spatially stable hybrid zone, except for one trait, belly plumage coloration, which has introgressed into the distribution of the white-collared manakin. This finding suggests possible sexual selection for this trait.

摘要

性选择如何影响杂种区的渐渗动态？Long 等人（2024 年）利用历史（1989-1994 年）和当代（2017-2020 年）的样本，量化了巴拿马金颈丛鸦（Manacus vitellinus）和白领丛鸦（M. candei）之间的杂种区的稳定性。他们的分析显示，除了一个特征，即腹部羽毛颜色外，杂种区具有空间稳定性，而这个特征已经渐渗到白领丛鸦的分布区。这一发现表明，该特征可能受到了性选择的影响。
