Current knowledge of gene flow in plants: implications for transgene flow
TL;DR: New data have implications for transgenic crops and depending on the specific engineered gene(s) and populations involved, gene flow may have the same negative impacts as those observed for traditionally improved crops; gene flow's idiosyncratic nature may frustrate management and monitoring attempts.
Journal ArticleDOI
Hybridization, glaciation and geographical parthenogenesis
TL;DR: It is argued that many cases of geographical parthenogenesis might be best seen as part of a broader pattern of hybrid advantage in new and open environments and might tell us more about the role of hybridization in evolution than about the roles of sex.
Journal ArticleDOI
Preserving the Information Content of Species: Genetic Diversity, Phylogeny, and Conservation Worth
TL;DR: Gene number is an important component of assessing conservation value, and Phylogenetic measures are better indicators of conservation worth than species richness, and measures using branch-lengths are better than procedures relying solely on topology.
Journal ArticleDOI
Does niche divergence accompany allopatric divergence in Aphelocoma jays as predicted under ecological speciation? Insights from tests with niche models.
TL;DR: The results do not support an ecological speciation model for Mexican Jay lineages because, in most cases, the allopatric environments they occupy are not significantly more divergent than expected under a null model.

Beyond neo-Darwinism--an epigenetic approach to evolution.
M.W. Ho,P.T. Saunders +1 more
TL;DR: It is proposed that “large” evolutionary changes could be the result of the canalization of novel developmental responses which arose from environmental challenges under conditions of relaxed natural selection, and moreover, that the canalized responses might involve cytoplasmic inheritance or maternal effects at least in the initial stages.
