speciation in ninespine stickleback: reproductive isolation and phenotypic divergence among cryptic species of japanese ninespine stickleback. | although similar patterns of phenotypic diversification are often observed in phylogenetically independent lineages, differences in the magnitude and direction of phenotypic divergence have been also observed among independent lineages, even when exposed to the same ecological gradients. the stickleback family is a good model with which to explore the ecological and genetic basis of parallel and nonparallel patterns of phenotypic evolution, because there are a variety of populations and species ... | 2013 | 23663028 |
