Natural selection in action during speciation

S Via - Proceedings of the National Academy of Sciences, 2009‏ - pnas.org
The role of natural selection in speciation, first described by Darwin, has finally been widely
accepted. Yet, the nature and time course of the genetic changes that result in speciation …

On the scent of speciation: the chemosensory system and its role in premating isolation

C Smadja, RK Butlin - Heredity, 2009‏ - nature.com
Chemosensory speciation is characterized by the evolution of barriers to genetic exchange
that involve chemosensory systems and chemical signals. Here, we review some …

[کتاب][B] Eco-evolutionary dynamics

Benefits and costs of hosting facultative symbionts in plant‐sucking insects: A meta‐analysis

SE Zytynska, K Tighiouart, E Frago - Molecular Ecology, 2021‏ - Wiley Online Library

The genetic mosaic suggests a new role for hitchhiking in ecological speciation

S Via, J West - Molecular ecology, 2008‏ - Wiley Online Library
Early in ecological speciation, the genomically localized effects of divergent selection cause
heterogeneity among loci in divergence between incipient species. We call this pattern of …
