divergent natural selection with gene flow along major environmental gradients in amazonia: insights from genome scans, population genetics and phylogeography of the characin fish triportheus albus. | the unparalleled diversity of tropical ecosystems like the amazon basin has been traditionally explained using spatial models within the context of climatic and geological history. yet, it is adaptive genetic diversity that defines how species evolve and interact within an ecosystem. here, we combine genome scans, population genetics and sequence-based phylogeographic analyses to examine spatial and ecological arrangements of selected and neutrally evolving regions of the genome of an amazonian ... | 2012 | 22512735 |
