Evolution in an Urbanizing World
Urbanization is happening all over the world. Everywhere you look, you can see that cities are expanding and new cities are being built. This is often at the expense of nature. There is not a lot of room for vegetation in cities and more and more existing vegetation and farmlands are being turned into urban... Continue Reading →
Think about a classic urban species. The first ones that come to mind are usually rats, pigeons and cockroaches. I’d bet that less than 10% of people reading this thought of a reptile. With cockroaches (and possibly ants) being the exception, most big names of the city are birds and mammals. Rats, mice, squirrels, (feral)... Continue Reading →
One of the outstanding questions in urban evolutionary biology is whether there are universal or predictable responses to urbanization, and if so, what factors influence urban tolerance. As small-bodied ectotherms, reptiles are particularly sensitive to many of the challenges of urban life. For example, reptiles appear to be more sensitive to habitat fragmentation than birds,...

Life in the city is stressful, for humans and wildlife! One of the main physiological traits thought to be impacted by the novel pressures of urban life, such as noise and light pollution, is stress hormone concentration. Nevertheless, no patterns have emerged across species. Allison Injaian and co-authors fill this gap in knowledge with their... Continue Reading →
