Adding a third dimension to the edge of a species' range: altitude and genetic structuring in mountainous landscapes

Article Abstract:

The article discusses the different patterns and the significance of employing the altitude gradients and genetic structuring while characterizing the mountainous landscapes. The variations observed in the gene flow and drift due to elevation are found to be the main factor affecting the distribution of genetic variation at different altitudes.

Evolutionary genetics: A ring of species

Article Abstract:

The model on how new species can arise through 'circular overlap' without interruption of gene flow through intervening populations is confirmed. The study shows that reproductive isolation can arise through 'isolation-by-distance' such that large distances themselves restrict gene flow. NOT DONE

Adaptive divergence overcoming gene flow

Article Abstract:

The prevalence of adaptive divergence despite the very high gene flow in the European flounder Platichthys flesus and other marine species is discussed.
