Evolution in an Urbanizing World
When you think of urban birds, you probably don't think of a flock of 20 lb wild turkeys. A friend of mine shared his recent encounter with a group of these modern dinosaurs in Cambridge, Massachusetts. Photo credits: Louis Neidorf Do you have a photo or video of an urban species doing something unusual? What... Continue Reading →
I'm partial to the creepy, crawly, scaly, slithering critters. I spend most of my time thinking about urban lizards, but recently started wondering about urban snakes. To my great disappointment, I wasn't able to find many recent publications on urban snakes, and most of what I did find looked at urban ecology and biodiversity, rather... Continue Reading →
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 →
In light of recent events, particularly the murder of George Floyd, harassment of Christian Cooper, and unjust actions against protesters supporting the #BlackLivesMatter movement, we at LITC want to acknowledge the systematic oppression and racism that exists in our field. We wholeheartedly support the Black community and communities of color, and firmly stand against racism.... Continue Reading →
Yesterday we shared some new research with you about the effects of light at night (ALAN) on anoles, featuring new research by contributor Chris Thawley. Today, we stick with that theme of activity at night and the night-light niche. In January (before I knew my fieldwork would be postponed indefinitely), I headed to the beautiful...

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 →
Urban areas are hot. The urban heat island effect causes urbanized regions to be significantly warmer than nearby forested areas, and the tropical islands of the Caribbean are no exception to this pattern. Just spend a few minutes in the noon heat in San Juan, Puerto Rico, and you will beg for the cool reprieve... Continue Reading →
The Common European Toad, Bufo bufo, is a pond-breeding amphibian found throughout Europe, including in urban environments. Ecological changes (e.g., predator communities) in anthropogenic habitats present novel challenges to the common toad, but abiotic changes (e.g., pollution) may also influence phenotypes in these landscapes. Nevertheless, we know relatively little about how these urban-dwellers (and specifically their toxins)... Continue Reading →
The Wuhan novel coronavirus is dominating the news, with reports of thousands infected and new cases reported worldwide every day. Are we at the verge of a pandemic? That's not a question I'm equipped to answer, and I encourage our readers to follow all advice from the CDC and WHO regarding the spread of the... Continue Reading →
The annual meeting of the Society for Integrative and Comparative Biology (SICB) is here! From January 3-7 biologists will convene in Austin, Texas 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 about... Continue Reading →
Milestones and more In 2019 we hit a lot of milestones. We turned 1 year old. We were featured in several major news outlets, including as a News Feature in PNAS, the Wildlife Society, and Wired Magazine! We reached over 13,000 visits since starting from (almost) every corner of the globe (we're looking at you,... Continue Reading →
Eastern Gray Squirrels, Sciurus carolinensis, are some of the most visible and well-known urban animals in the Northeastern United States. Prior to European settlement of the region, the black morph of S. carolinensis ("melanistic") was much more abundant. Scientists have hypothesized that the dark pelt was advantageous in the old growth forests that used to cover the region.... Continue Reading →
In the month of November we asked to hear from you during our first annual November Comment Contest. Now that the month is over, we've tallied the comments, responses, and likes and we're pleased to announce our two winners: Kristin Thompson and Kevin Aviles-Rodriguez! They'll get to pick the urban organisms featured on the next... Continue Reading →
When we think of urban organisms, we often don't think of aquatic organisms. But wetlands exist in the urban matrix, and aquatic and amphibious species are impacted by habitat changes associated with urbanization. A recent study published in Ecology and Evolution by Jared Homola, Cynthia Loftin, and Michael Kinnison dug into the population genetics of... Continue Reading →
