Evolution in an Urbanizing World
As urbanization continues to reshape landscapes, its effects on wildlife have become a subject of growing concern. In the unique context of Cuba, a recent study focused on an endemic lizard species, Anolis homolechis, found in both natural and suburban environments. This in-depth study relied on adapted tracking methods deployed over several years and explored... Continue Reading →
Anolis lizards (known as anoles) are models for studying evolution in the wild. Not only do anoles have a history of repeatedly diversifying to specialize in the same types of microhabitats in the same ways across the Greater Antilles (i.e., they are an adaptive radiation), these lizards also have a tendency to adapt on rapid...

Pineapples and Whales recently created an infographic about parallel evolution in urban anole populations! It's based on this study in Nature Ecology & Evolution: Parallel selection on thermal physiology facilitates repeated adaptation of city lizards to urban heat islands.
New Orleans is a great city — good food, good people, good drinks. But the best part about New Orleans? LIZARDS! Keep your eyes open and you're likely to see lizards crawling on the trees, fences, buildings, and trashcans. Two species are common to the city: Anolis carolinensis, which are native to the Southeast USA,... Continue Reading →
As some of you may know by now, one of our co-editors/founders of this blog, Kristin Winchell, researches anoles adapting to urban areas. So of course we get excited to see anoles caught on camera in urban areas. This week's observation is a green anole on campus at Loyola University in New Orleans, captured by... 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...

Urbanization is becoming a huge concern and many researchers at SICB 2020 wanted to study the effects it has on the surrounding wildlife. Laura Taylor, an undergraduate student at Trinity University, looked specifically at how urbanization and artificial light at night (ALAN) effected both the physiology and the behavior of anoles. Green anoles (Anolis carolinensis),... Continue Reading →
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 →
