Evolution in an Urbanizing World
You can't live near humans if you're afraid. Fleeing constantly can be very costly, so generally animals near humans tend to become accustomed to them. A new research compares skinks in Mo'orea island to see if their escape response varies and if skinks living with more humans have adjusted their responses accordingly.
A major outstanding question in urban evolution (and evolutionary biology in general) is whether adaptation occurs in similar ways in different populations and across species boundaries. In other words, can the common selective pressures of urban environments lead to convergent adaptation? In my doctoral research, I found that the Puerto Rican crested anole, Anolis cristatellus, adapted... Continue Reading →
Kevin Aviles-Rodriguez, a contributor here at LITC, studies urban adaptation and behavior of Anolis lizards. Previously, we told you all about Kevin's research on escape behavior of urban versus forest anoles, which was Kevin's MS research. During his PhD, Kevin has been focusing more on landscape genetics and the morphological impacts of hurricane Maria in urban... Continue Reading →
In the second of four urban anole presentations at Evolution, Emmanuel D'Agostino does a great job summarizing new research by LITC contributor Chris Thawley. Chris' post-doc research has really delved into the night-light niche and ALAN, a topic that is no stranger to this blog (check out: It’s Lit in the City, Is Artificial Light Changing Pigeon...

Anole lizards are adapting to urbanization. Anolis cristatellus in particular has rapidly and repeatedly evolved larger toepads with more lamellae (among many other trait shifts) in urban environments across Puerto Rico when compared to nearby forest environments. But one question that has been bugging me and Travis Hagey for years is how exactly are the toepads getting... Continue Reading →
I’m excited to share an update on my foray into urban ecology and evolution research as an undergraduate! I've been working in the Revell Lab at the University of Massachusetts Boston since my freshman year. I've reported here before about some of my experiences in the field working on urban anoles. Over the past couple of... 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 →
Night life in the city can be much brighter and artificial lighting can be a significant source of new evolutionary directions for city dwellers. A recent study by Hopkins et al. (2018) researchers reviewed how Artificial Light At Night (ALAN) can drive evolutionary change in a theoretical population. How can artificial light at night (ALAN) drive evolution?...
