title: Data from: The role of mate competition in speciation and divergence: A systematic review

description: Competition for mates can play a critical role in determining reproductive
 success, shaping phenotypic variation within populations, and influencing
 divergence. Yet, studies of the role of sexual selection in divergence and
 speciation have focused disproportionately on mate choice. Here, we
 synthesize the literature on how mate competition may contribute to
 speciation and integrate concepts from work on sexual selection within
 populations – mating systems, ecology, and mate choice. Using this
 synthesis, we generate testable predictions for how mate competition may
 contribute to divergence. Then, we identify the extent of existing support
 for these predictions in the literature with a systematic review of the
 consequences of mate competition for population divergence across a range
 of evolutionary, ecological, and geographic contexts. We broadly evaluate
 current evidence, identify gaps in available data and hypotheses that need
 testing, and outline promising directions for future work. A major finding
 is that mate competition may commonly facilitate further divergence after
 initial divergence has occurred, e.g., upon secondary contact and between
 allopatric populations. Importantly, current hypotheses for how mate
 competition contributes to divergence do not fully explain observed
 patterns. While results from many studies fit predictions of negative
 frequency dependent selection, agonistic character displacement, and
 ecological selection, results from ~30% studies did not fit existing
 conceptual models. This review identifies future research aims for
 scenarios in which mate competition is likely important but has been
 understudied, including how ecological context and interactions between
 mate choice and mate competition can facilitate or hinder divergence and
 speciation.
