Understanding the mechanisms underlying species coexistence and the maintenance of highly diverse communities has been a central issue in ecology for decades. Historically much emphasis has been made on the importance of limiting similarity, showing that species should differ in their ecological niche e.g. in their resource utilization to allow stable coexistence. However, recent theoretical studies have also revealed that species can also coexist over ecological scales by being sufficiently similar, leading to distinctive clustering patterns of species distribution along the niche axis with groups of similar species separated by gaps in between.
While various mechanisms have been shown to promote the emergence of niche clustering and its stability over time, all the mechanisms studied so far still rely on competition among species. Despite the potential generality of niche clustering patterns recently outlined in several theoretical and empirical studies, we still know nothing of how these clusters translates into more complex communities including trophic interactions. Here, by studying a classical predator-prey Lotka-Volterra model, we investigate how competition and predation interact to shape the distribution of prey and predators along their niche axes and lead to the emergence of clusters on these axes.
