Social selection parapatry in an Afrotropical sunbird

Abstract: 25The extent of range overlap of incipient and recent species depends on the type and magnitude of 26 phenotypic divergence that separates them. Trait divergence by social selection likely initiates 27 many speciation events, but may yield niche-conserved lineages predisposed to limit each others' 28 ranges via ecological competition. Here we examine this neglected aspect of social selection 29 speciation theory in relation to the discovery of a non-ecotonal species border between sunbirds. 30 We find that N… Show more

“…13–30) from the supposed ”eastern” core region of the latter taxon. To reduce spatial dimensionality for cline fitting analyses (see below), we defined a c. 350 km‐long transect between western‐ and easternmost populations (Figure 1b) and projected the remainder onto this line, using the “distance to nearest hub” algorithm in qgis 3.8 (QGIS Development Team, 2019; see also McEntee et al, 2016).…”
