Evolution in an Urbanizing World
The common wall lizard (Podarcis muralis) offers a great opportunity to study how humans are influencing the course of evolution. These lizards have a large native range, covering much of Southern Europe, but are also successfully established in many places, including Cincinnati, Ohio, USA. The common wall lizard was introduced to Cincinnati in the early... Continue Reading →
Artificial light at night alters diurnal and nocturnal behavior and physiology in green anole lizards Laura A.Taylor, Christopher J. Thawley, Olive R.Pertuit, Abigail J.Dennis, Isabela R.Carson, ChenTang, Michele A.Johnson Abstract Artificial light at night (ALAN) disrupts biological rhythms across widely diverse organisms. To determine how energy is allocated by animals in different light environments, we investigated the... 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,...

This week we are cross-posting (again) from Anole Annals. Check out the original post here, written by Pavitra Muralidhar. How we perceive and interact with the world is strongly shaped by natural light. How much light there is at a given time determines whether we’re sleepy or awake, and whether we’re bracing for winter or... Continue Reading →
This week we are cross-posting from Anole Annals. Check out the original post here. Seven years ago I asked for the help of Anole Annals readers as I started to think about how different species of anoles throughout the Caribbean tolerate urbanization. This question, it turned out, was a lot more complex than I had... Continue Reading →
From Anoles to Indian Agamids to Australian Water Dragons to Western Fence Lizards, lizards from diverse branches of the squamate tree are proving themselves in urban environments. Add one more species to this growing list of urban lizards: Brazilian lagartixas, Tropidurus hispidus. In a recent paper, Antonio de Andrade examined the abundance and habitat use of...

We've talked before here on Life in the City about behavioral shifts related to fear and boldness in urban animals (check out: Skirting Skinks: Are Lizards Learning to Live Among Humans?, No city for shy dog, Concrete Escape: Increased Wariness of Anoles). Although it is clear that urban species experience behavioral modifications in response to urban... 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 →
