WebAug 22, 2011 · Theoretical models predict that speciation can occur among continuously distributed populations isolated by distance alone, particularly when subject to divergent ecological selection [1–3].Ring species -- cases where two sympatric forms are connected by a chain of intergrading populations encircling a central geographic barrier [4–7] -- … WebDec 5, 2012 · Contact zones between subspecies or closely related species offer valuable insights into speciation processes. A typical feature of such zones is the presence of clinal variation in multiple traits. The nature of these traits and the concordance among clines are expected to influence whether and how quickly speciation will proceed. Learned signals, …

WebJan 14, 2008 · Collections in southern Ecuador show that the contact zone is about 5 km wide, half the width of the narrowest clines between colour pattern races of H. erato. The narrowness of this dine argues that very strong selection (s ≅ 1) is maintaining the parapatric distributions of these two species. ...
