New Lit Alert: Urbanization drives adaptive evolution in a Neotropical bird

Urbanization drives adaptive evolution in a Neotropical bird Rilquer Mascarenhas, Pedro Milet Meirelles, Henrique Batalha-Filho Abstract Urbanization has dramatic impacts on natural habitats and such changes may potentially drive local adaptation of urban populations. Behavioral change has been specifically shown to facilitate fast adaptation of birds to changing environments, but few studies have investigated the genetic mechanisms... Continue Reading →

Back to the Basics: What is Urban Evolution?

Urban evolution can have different meanings depending on what field you come from. If you are an urban planner, it might mean that urban areas are getting larger, even using sustainable energy sources where they didn't previously. For some architects it may mean that they now figure out how to put green roofs on buildings.... Continue Reading →

Urban Genes

urban selection genes

Urbanization impacts species in many different ways, including behavior, morphology, and physiology. Although many of the documented phenotypic shifts show evidence of a genetic basis, the actual genetic differences and the genes they occur in are unknown for most urban adaptations. In fact, it seems we know very little at the genetic level regarding which... Continue Reading →

Proc. B Special Issue: Can Random Processes Drive Parallel Evolutionary Responses to Cities?

urban white clover

Continuing our coverage of the recent Proc. B Special Issue on urban evolution, James Santangelo (PhD candidate at University of Toronto Mississauga) tells us about his recent manuscript: One of the outstanding questions in evolutionary biology concerns the extent to which different species — or different populations of a single species — evolve the same genes or...
