Journal ArticleDOI
Non-Allopatric Speciation in Animals
TL;DR: The extent to which the theory and evidence amassed since 1963 warrant a major change in views of animal speciation is reviewed, and the theory of stasipatric speciation and purported cases of sympatrics associated with a shift to a new host are reviewed.
Journal ArticleDOI
Speciation reversal and biodiversity dynamics with hybridization in changing environments
TL;DR: A loss of environmental heterogeneity causes a loss of biodiversity through increased genetic admixture, effectively reversing speciation, and the evolutionary ecology of speciation reversal ought to be fully integrated into conservation biology.
Journal ArticleDOI
Phylogenetic comparative methods and the geography of speciation
TL;DR: It is concluded that interspecific phylogenies are unable to test alternative hypotheses concerning the geography of Speciation rigorously because of the lability of geographical ranges and the lack of correlation between the role of adaptive processes and geographical mode of speciation.
Journal ArticleDOI
Bureaucratic Mischief: Recognizing Endangered Species and Subspecies
Stephen J. O'Brien,Ernst Mayr +1 more
TL;DR: The interpretive difficulties posed by molecular results for four endangered groups are summarized and three opinions from the Solicitor's Office of the Department of the Interior have ruled with the force of precedent that hybrids between endangered species, subspecies, or populations cannot be protected.
Journal ArticleDOI
Reinforcement drives rapid allopatric speciation
TL;DR: It is shown that reinforcing natural selection has resulted in significant premating isolation of a population in the contact zone not only from the other lineage but also, incidentally, from the closely related main range of its own lineage.
