The analysis of mechanisms how populations differentiate and new species arise, is fundamental for understanding the evolution of biological diversity. Mating preferences and sexually selected characters can rapidly diverge between populations, and this probably can lead to premating reproductive isolation and hence the evolution of new species. We plan to investigate the role of complex communication systems (here acoustic communication in grasshoppers) for the radiation of species flocks. A molecular phylogeny will be used first as a reference frame to study the evolution of signals (male songs) and second to compare speciation rates between communicating and non-communicating groups as well as among groups that differ in the complexity of their communication system.

分析种群分化和新物种产生的机制是理解生物多样性进化的基础。交配偏好和性选择特征会在种群之间迅速分化，这可能会导致交配前的生殖隔离，从而导致新物种的进化。我们计划调查的作用，复杂的通信系统（这里的声通信蝗虫）的辐射的物种群。一个分子生物学将首先作为一个参考框架来研究信号（男性歌曲）的演变，其次比较物种形成率之间的通信和非通信组，以及不同的群体之间的复杂性，他们的通信系统。
