Geographic contact between sister lineages often occurs near the final stages of speciation, but its role in speciation's completion remains debated. Reproductive isolation may be essentially complete prior to secondary contact. Alternatively, costly interactions between partially reproductively isolated species – such as maladaptive hybridization or competition for resources – may select for divergence,...
Contact zones between recently diverged taxa provide opportunities to examine the causes of reproductive isolation and the processes that determine whether two species can coexist over a broad region. The Pacific wren (Troglodytes pacificus) and winter wren (Troglodytes hiemalis) are two morphologically similar songbirds that started diverging about 4 million years ago, older than most sister species...
How species evolve reproductive isolation in the species‐rich Amazon basin is poorly understood in vertebrates. Here, we sequenced a reference genome and used a genome‐wide sample of SNPs to analyze a hybrid zone between two highly cryptic species of Hypocnemis warbling‐antbirds—the Rondonia warbling‐antbird (H. ochrogyna) and Spix's warbling‐antbird (H. striata)—in a headwater region of southern...
