The Geography of Stickiness: What Gecko Feet Reveal about Evolution Like in Anolis lizards, the evolution of adhesive toepads in geckos is often seen as a key innovation, allowing these lizards to exploit vertical environments. Gecko toepads are among the most advanced in the animal kingdom –…

A Closer Look at Color: Female-Driven Dewlap Dichromatism in Anoles Dewlaps—the extensible throat ornaments of anoles—are classically viewed as male secondary sexual traits used in mate attraction and rival assessment. However, many species exhibit fully developed female dewlaps, and in numerous…

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…

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…

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…

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...

Sad to have missed some great talks yesterday, but today there is another great lineup of #Anolis talks at #SICB2025! Check out the list curated by @anoleannals.bsky.social : www.anoleannals.org/2024/12/22/a...

Figured I couldn’t miss out on all the cool science happening on this app so… here I am! Also, shameless plug for my #SICB2025 talk on Tuesday… Come learn about cool brown anole skin color science at 1:45 in International Salon 4 (and also see some cool ovary data 👀)!
