Roe deer (Capreolus spp.) are a little odd. They are one of only a few placental mammals—and the only genus among even‐toed ungulates—capable of putting embryonic development “on ice”, also known as embryonic diapause (Figure 1). It would seem such an unusual trait is probably the product of natural selection, but a big question is, how does selection for important traits, such as diapause, interact with the historical demography of a species? In a ‘From the Cover’ article in this issue of Molecular Ecology , de Jong et al. (2020) demonstrate that selection is acting on genes associated with reproductive biology in roe deer, despite heightened genetic drift due to reduced effective population size through the Pleistocene.

冰鹿:尽管更新世有效种群数量有限,但仍要选择。

Capreolus spp。)有点奇怪。它们是仅有的少数胎盘哺乳动物之一,并且是仅有蹄类的唯一属,能够将胚胎发育“置于冰上”,也被称为胚胎滞育(图1)。看起来这种不寻常的性状可能是自然选择的产物,但一个大问题是,对重要性状(例如滞育)的选择如何与物种的历史人口统计学相互作用?在本期《分子生态学》的一篇“从封面”中,de Jong等人。(2020)证明选择是在与with的生殖生物学相关的基因上起作用,尽管由于更新世而导致的有效种群数量减少,导致遗传漂移加剧。
