Spoil Islands in Florida: an Opportunity for Anole Experiments in the Wild Invasive species are a growing problem across our increasingly globalized planet. They are often adept at establishing stable population sizes very quickly, which allows them to outcompete native species for access to…

Not All Mothers Know Best: Geographic Variation in Brown Anole Nesting Behavior Anolis sagrei (brown anole, Figure 1) is a small species, native from Cuba, that invaded Florida around 1800. Me, I am from Brazil, and this is the story of how I made some interesting discoveries about the brown…

Changing Gears (and Colors): Investigating Color Change in Green Anoles Using Computer Vision Green anoles (Anolis carolinensis), also described as the American chameleon, can change between brown and green coloration at will in a process known as physiological color change. Deciphering the…

Rebreathing Semi-aquatic Anoles: Just a Scuba Tank… or Something More? Over the past several years, semi-aquatic anoles experienced a bit of viral fame for “scuba diving," a nickname for their ability to rebreathe a bubble of air over their nostrils while diving underwater. Rebreathing allows…

Brown Anoles as a Backyard Ecosystem Menace Galveston reader A.J. Watkins writes in: I am in Galveston Texas, and I am literally in tears. Being a Port city, we have been invaded by the Cuban anoles that have obviously come in off the shipping boats. All I can say is they have caused complete…

Second Invasion of Africa by the Festive Anole Yes, the brown (aka, festive) anole is at it again. Now it's turned up on the island of Bioko in the Gulf of Guinea. As Malanza et al. report in Herpetological Notes, this is the second introduction of the species to Africa, the first occurring in…

A Yellow Green Anole Reader Gary Dick tells us: I encountered the hatchling pictured about 10 years ago on my patio.  Part of a small population in my specific area.  Best I can tell, it was achromic Green anole.  What do you think? A little additional info about this lizard:  it’s from a…

Can Anoles Regenerate Their Skin? Christopher Brown on his blog Field Notes writes: "We may never acquire the gift evidenced by this anole I saw on our retaining wall last weekend: the ability to regenerate large portions of one’s own body after an accident or an encounter with a predator. I was…

More on Anole Eye Spots Some green anoles sometimes temporarily develop a black spot behind their eyes. We had a great post on why this happens in 2011. Spoiler: it's a sign of stress. Reader Seth Whaland has provided interesting observations: In August of this year, I was on the Butler Hike &…

Dewlap Drama in the Slender Anole: a Tale of Two Throats Color us intrigued! In the world of Anolis lizards, the dewlap—a colorful throat fan used for communication—is one of the most iconic features. It’s been flaunted, flashed, and filmed in countless studies of behavior and adaptive radiation.…

A Three-Legged Lizard Mystery Anole Annals has featured a series of posts on three-legged lizards over the years (e.g., here and here). Now we need help. Some time around 2017, April Brown contributed a photo of a brown anole missing both of its forelegs. The photo was taken in Winter Park, FL.…

Inter-island hostilities A clip of a much longer video: Two anoles, the ubiquitous Jamaican (Graham’s, Anolis grahami), which adorns every wall in Bermuda, and the seldom seen Barbados (A. extremus), just an occasional shadow in the shade, somehow finding themselves on the desirable territory of…

Anolis cannibalis I live in Bermuda. Many years ago, my daughter and I witnessed a large male Graham’s anole devour a small female, same species. We were horrified as we had watched these particular individuals so often we’d named them…the male was Pat Rafter as he spent much of his time up by the…

Understanding Animal Behaviour, a Non-Fiction Graphic Novel I dislike textbooks. I still remember the dismay as an undergraduate student of spending all that money to buy hugely expensive textbooks. And if there was any sense of excitement on cracking the cover of a textbook for a new course, it…

What is the Proper Scientific Name of a Lizard when the Original Latin Is Incorrect? Peter Mudde writes: I am chairman  of Lacerta, the Dutch Herpetological society. I also am a regular contributor to the magazine Lacerta. Lacerta  recently made an "Anolis special." We are preparing a printed…

Anything New on Time Budgets in Anoles? A couple of my REU students from 2008 "rediscovered" their field notes and want to finish what they didn't get done that summer. We were on St. Vincent and their project involved time allotment throughout the day by the anoles (Anolis trinitatis and A.…

New Introduced Population of Anolis carolinensis (Green Anole) in Norfolk, Virginia Growing up in Florida, I was used to seeing Green Anoles, so when I moved to Virginia to start my PhD at Old Dominion University, I wasn’t surprised to see Green Anoles venturing around Norfolk. If anything, seeing…

An accurate representation of #SICB2025. Loved @princetonvaughn.bsky.social’s talk on anole morphological differences in urban vs. rural settings!

Victor Munteanu is studying animals who live in trees and what happens when they fall! This is an obvious risk to animals that live their whole lives in trees. Cats? Great at falling. Pandas? God bless them, not so much. Victor’s focusing on lizards for this project. #SICB2025

@alliemartin.bsky.social Gives an excellent talk on the balance male and female Anolis lizards have to maintain between staying warm, escaping predators, and capturing mating opportunities! #SICB2025

Many great anole talks and posters between today, tomorrow, and Tuesday! Figure out where/when they all take place here: www.anoleannals.org/2024/12/22/a...

On Sunday Claire Williams of U Nevada is presenting a poster from a collaboration on interactions between the #anolis lizard guy microbiome and thermal acclimation #sicb2025

Last but not least, Emily Stelling from Christine Lattin’s LSU lab will present a Saturday poster on the effects of captivity on the #anolis lizard stress response #sicb2025

So excited to be at #SICB2025! Come by International Salon 7 Sunday at 9:45 am if you’re interested in seeing my talk entitled “Diving in semi-aquatic Anolis lizards results in heat loss with sex-specific cooling tolerance”
