Evolution in an Urbanizing World
We invite contributions to a special feature on evolution in urban environments to be published in Evolutionary Applications in 2020. Instructions on how to be considered for this special feature are provided below. Urban areas are among the fastest growing ecosystems on earth and the driver of local and global climate change. Despite this importance, little... Continue Reading →
The annual Evolution meeting co-sponsored by the Society for the Study of Evolution, Society of Systematic Biologists, and American Society of Naturalists is coming soon to Providence, Rhode Island this June 21-25th! This meeting usually has a strong representation of researchers working in urban systems and we hope this year will be no different. Are... Continue Reading →
An outstanding question in urban evolutionary biology is what factors influence a species' success in urban environments. This is a topic we've talked about before (check out Urban Adaptation in Mammals) and several other recent papers have tackled this topic. A variety of factors may influence whether or not a species occupies an urban environment... Continue Reading →
This week we wish you a Happy Valentine's Day, urban anole style! Here's some photos I took of Anolis grahami in Kingston, Jamaica a couple of weeks ago. Anoles have a colorful throat fan (called a dewlap) that they extend to signal to other males in dominance displays and to females they would like to mate... Continue Reading →
Mammals are some of the most easily recognizable and endearing critters to share our cities with us. Who doesn't love a cute bunny or squirrel in a city park? Or a fox or raccoon slinking through the streets at night. Even city rats can be endearing. Despite the commonality of these species, urban areas are... Continue Reading →
One thing I always wonder when I see birds flying around cities is "where are they nesting???" Fortunately, the Audubon Society has an answer for that question - many birds nest in and on buildings and other anthropogenic structures. For example: Chimney swifts nest inside of chimneys Cliff swallows build mud nests on the sides... Continue Reading →
This post is part of our series covering the large number of urban evolution manuscripts that were published in August in the special issue "The Evolution of City Life" in the Proceedings of the Royal Society B. Urban environments are often composed of novel communities of native and introduced species. In several cities in Germany,... Continue Reading →
The Smithsonian Channel and Day's Edge Productions have put together a fantastic mini-series and a full-length documentary on anole evolutionary research. Episode 7 of the miniseries and part of the full-length movie feature urban lizards and urban evolution research by myself and my collaborators, Shane Campbell-Staton (UCLA) and Jason Kolbe / the Kolbe lab (U. Rhode Island). Check out... Continue Reading →
The annual meeting of the Society for Integrative and Comparative Biology (SICB) is almost here! From January 3-7 biologists will convene in Tampa, Florida to share the latest and greatest from a broad range of research areas. Urban evolution talks have a strong showing at the meeting this year, and we would like to hear... Continue Reading →
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 →
As the field of urban ecology and evolution advances, one major issue consistently jumps out at me: the lack of information on basic ecology and natural history of many species in urban environments. Such information provides a background for hypothesis driven research, a context for interpreting results, and a comparative baseline. Evolutionary studies, particularly those framed...

Above: Fig. 2 from Rivkin et al: many species have been shown to adapt to cities. Thompson et al. ask whether or not this could lead to speciation. Organisms that persist in urban environments are subject to novel selective pressures as they exploit this novel niche space. We now know that this ecological shift can lead to... Continue Reading →
In cities the number and types of predators drastically differ from nearby rural and "natural" areas. This often means that the biggest threat prey species have to face in cities are domestic predators (dogs and cats) or generalist "mesopredators" like raccoons, coyotes, or foxes. That is, unless you consider the threat from humans, and in... Continue Reading →
In their recent contribution to the special issue on urban evolution in Proceedings B, Sarah Diamond and team share their exciting results on detecting parallel and non-parallel physiological responses to the urban heat island in acorn ants (paper here). This is the first of several posts to come on the recent special issue on urban evolution... Continue Reading →
