In this study we examine the microevolutionary processes leading to reproductive and genetic differentiation of coastal and island populations of S. salamandra by surveying genetic diversity, ...

Rates of species formation vary widely across the tree of life and contribute to massive disparities in species richness among clades. This variation can emerge from differences in ...

Cuckoos – which lay their eggs in nests of other birds – have higher speciation rates when they lay their eggs in a broader range of host bird species’ nests, a new study reports. This higher ...
