Evolution in an Urbanizing World
As of 2018, 55% of the world’s human population lives in villages, towns, or cities, and this figure grows annually as people increasingly adopt the urban lifestyle. The environmental consequences of this urban expansion are vast: grasslands, forests, and wetlands are replaced by roads, sidewalks, and buildings that make up the residential and commercial infrastructure...

Detecting patterns of vertebrate biodiversity across the multidimensional urban landscape Marina Alberti & Tianzhe Wang Abstract Explicit characterisation of the complexity of urban landscapes is critical for understanding patterns of biodiversity and for detecting the underlying social and ecological processes that shape them. Urban environments exhibit variable heterogeneity and connectivity, influenced by different historical contingencies,... Continue Reading →
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 →
Phenotypic variation in urban environments: mechanisms and implications M.J. Thompson, P. Capilla-Lasheras, D.M. Dominoni, D. Réale, & A. Charmantier Abstract In the past decade, numerous studies have explored how urbanisation affects the mean phenotypes of populations, but it remains unknown how urbanisation impacts phenotypic variation, a key target of selection that shapes, and is shaped...

Genetic differentiation in pesticide resistance between urban and rural populations of a nontarget freshwater keystone interactor, Daphnia magna Kristien I. Brans, Rafaela A. Almeida, Maxime Fajgenblat Abstract There is growing evidence that urbanization drives adaptive evolution in response to thermal gradients. One such example is documented in the water flea Daphnia magna. However, organisms residing in urban lentic... Continue Reading →
