Evolutionary predictions can only be as good as the models on which they are based. Traditionally, evolutionary models are kept as simple as possible, with the idea that simple models are more easily tractable and that their conclusions are more general and robust. These models tend to focus on how selection acts on the phenotype and on the phenotypic response patterns to environmental...

At the sea shores of the European part of Northern Atlantic, periwinkles of the genus Littorina (subgenus Neritrema) are represented by two sister groups of closely related species: “obtusata” (L. obtusata, L. fabalis) and “saxatilis” group (L. saxatilis, L. arcana, L. compressa). Moreover, most of the species, especially, L. saxatilis, tend to form ecotypes along shore’s ecological gradient....

9. Male mate choice and sexual selection

A vast majority of studies in sexual selection focus on only two mechanisms, male -male competition and female choice. Yet clearly, both male mate choice and female competition are important factors in sexual selection. I will review this – with a focus on male mate choice -, using Livebearing fishes of the family Poeciliidae as an example. There are surprisingly many examples of male mate...
