New Lit Alert: The impact of urbanization on outcrossing rate and population genetic variation in the native wildflower, Impatiens capensis

The impact of urbanization on outcrossing rate and population genetic variation in the native wildflower, Impatiens capensis L. Ruth Rivkin and Marc T. J. Johnson Abstract Cities are one of the fastest growing ecosystems on the planet, and conserving urban biodiversity is of primary importance. Urbanization increases habitat fragmentation and may be particularly problematic for... Continue Reading →

New Lit Alert: Recent spread of blue tits into the Barcelona urban environment: morphological differences and the role of balanced dispersal

Recent spread of blue tits into the Barcelona urban environment: morphological differences and the role of balanced dispersal Juan Carlos Senar & Mats Björklund Abstract Rates of phenotypic change are greater in cities than in any other habitat. Consequently, urban habitats are an ideal experimental area to study contemporary evolution and adaptation. A key question... Continue Reading →

New Lit Alert: Bioindicator snake shows genomic signatures of natural and anthropogenic barriers to gene flow

Bioindicator snake shows genomic signatures of natural and anthropogenic barriers to gene flow Damian C. Lettoof, Vicki A. Thomson, Jari Cornelis, Philip W. Bateman, Fabien Aubret, Marthe M. Gagnon, and Brenton von Takach Abstract Urbanisation alters landscapes, introduces wildlife to novel stressors, and fragments habitats into remnant ‘islands’. Within these islands, isolated wildlife populations can... Continue Reading →

Evolution 2019: Evolution Takes Flight: Population Genetics of Feral Pigeons (Columba livia) in the Northeastern United States

As you may have guessed by now, urbanization changes the natural landscape and this can have consequences for the organisms that live in them. Feral pigeons, which had been domesticated thousands of years ago and transported globally by humans, are not immune to rapid urbanization impacts. Previous studies have shown that there can be inbreeding... Continue Reading →
