Strong yet incomplete reproductive isolation in is not contradicted by other lines of evidence: A reply to Toews et al.

Toews et al. assert that strong reproductive isolation in is inconsistent with other lines of evidence. Here, we discuss how strong yet incomplete reproductive isolation is consistent with other results from this system.

Implications for evolutionary trends from the pairing frequencies among golden-winged and blue-winged warblers and their hybrids.

Extensive range loss for the Golden-winged Warbler () has occurred in areas of intrusion by the Blue-winged Warbler () potentially related to their close genetic relationship. We compiled data on social pairing from nine studies for 2,679 resident to assess evolutionary divergence. Hybridization between pure phenotypes occurred with 1.

Gigantism and the potential for interference competition in the rotifer genus Asplanchna.

Laboratory experiments showed that A. bright-welli could outreproduce, or coexist with, A. silvestrii only when the absence of dietary tocopherol prevented the latter from transforming to the giant cruciform and campanulate morphs.
