Heterospecific mating interactions as an interface between ecology and evolution

Reproductive interference (costly interspecific sexual interactions) are well-understood to promote divergence in mating-relevant traits (i.e. reproductive character displacement: RCD), but it can also reduce population growth, eventually leading to local extinction of one of the species. The ecological and evolutionary processes driven by reproductive interference can interact with each other. These interactions are likely to influence whether the outcome is co-existence or extinction, but remain little studied. In this paper, we first develop an eco-evolutionary perspective on reproductive interference by integrating ecological and evolutionary processes in a common framework. We also present a simple model to demonstrate the eco-evolutionary dynamics of reproductive interference. We then identify a number of factors that are likely to influence the relative likelihoods of extinction or RCD. We discuss particularly relevant factors by classifying them into four categories: the nature ...

生殖干扰（Reproductive interference，即代价高昂的种间性相互作用）现已被广泛认知为可推动交配相关性状的分化（即生殖性状置换：RCD），但该过程同时也会降低种群增长速率，最终导致其中一个物种在局部区域灭绝。由生殖干扰驱动的生态过程与演化过程可彼此发生相互作用，这类相互作用很可能会影响最终结局为物种共存还是灭绝，但目前相关研究仍较为匮乏。本研究首先通过将生态过程与演化过程整合至统一框架中，构建了针对生殖干扰的生态-演化研究视角；同时我们还提出了一个简化模型，用以阐释生殖干扰的生态-演化动力学特征。随后我们确定了若干可能影响灭绝或RCD发生相对概率的因素，并将其中尤为相关的因素划分为四大类别展开讨论：其本质……
