过去三十年的研究表明，基于生态的外部繁殖障碍可以迅速产生早期物种，但当环境发生变化时，这种障碍也会迅速消失，导致早期物种崩溃。因此，理解无条件的、“内在的”生殖障碍的进化对于理解生物多样性的长期积累是很重要的。在这篇文章中，我们考虑生态学在内在生殖隔离进化中的作用。我们认为，这一主题已经陷入了学科之间的鸿沟：虽然进化生态学家传统上关注共同发生的生态型之间外在隔离的快速进化，但研究其他分类群内在隔离的物种形成遗传学家很少关注其进化的生态背景。我们认为，为了缩小这一差距，进化生态学必须将其重点扩展到快速适应和传统模型系统之外。综合几个子领域的数据，我们提出了支持和反对不同形式的生态适应作为内在隔离的促进因素的间接证据，并讨论了可能重要的替代力量。最后，我们概述了一些互补的方法，这些方法可以更好地解决生态在非短暂性生殖障碍和非短暂性物种进化中的作用。
Research over the past three decades has shown that ecology-based extrinsic reproductive barriers can rapidly arise to generate incipient species—but such barriers can also rapidly dissolve when environments change, resulting in incipient species collapse. Understanding the evolution of unconditional, “intrinsic” reproductive barriers is therefore important for understanding the longer-term buildup of biodiversity. In this article, we consider ecology’s role in the evolution of intrinsic reproductive isolation. We suggest that this topic has fallen into a gap between disciplines: while evolutionary ecologists have traditionally focused on the rapid evolution of extrinsic isolation between co-occurring ecotypes, speciation geneticists studying intrinsic isolation in other taxa have devoted little attention to the ecological context in which it evolves. We argue that for evolutionary ecology to close this gap, the field will have to expand its focus beyond rapid adaptation and its traditional model systems. Synthesizing data from several subfields, we present circumstantial evidence for and against different forms of ecological adaptation as promoters of intrinsic isolation and discuss alternative forces that may be significant. We conclude by outlining complementary approaches that can better address the role of ecology in the evolution of nonephemeral reproductive barriers and, by extension, less ephemeral species.
