SICB 2019: Tail Autotomy Happens More When the Tail Stores More Energy
One of the most interesting features of many lizards, including anoles, is that they can willingly, and actively, lose their tails to escape predators. While it might seem counterintuitive to lose a large body part, it’s better than being eaten! … Continue reading

Genomic signatures of climate adaptation in Anolis cybotes
Katharina Wollenberg Valero & Ariel Rodríguez Thermal adaptation is the evolution of the ability to persist in novel thermal environments. Phenotypic characters that allow such adaptation, as well as the resulting shifts in the geographic distributions of species, are an … Continue reading

Anole Visual Ecology, Sans Vision
A riddle: What has four legs, eagle eyes, and can change colors? Anoles are extremely visual animals, with vision being the primary sensory mechanism through which they perceive their surroundings. Accordingly, their vision is excellent, at least during the daytime. … Continue reading

Things We’d Like to Learn
Last summer I accompanied Martha Muñoz on her trip to the DR. Earlier this month I came to Harvard to present an overview of her study of thermoregulation in the cybotes clade of anoles at various locations and altitudes, and … Continue reading
Anole Research at Animal Behavior Meeting in Summer of 2011
Thom’s recent post on the upcoming SICB meeting reminded me that I was yet to share the anole research I learned about at the Animal Behavior Meeting this past summer in Bloomington, Indiana. There were just a handful of presentations … Continue reading

Challenges and Resources for the Post-genomic Era of Anole Research
The Anolis carolinensis genome represents the first annotated squamate genome and provides a valuable resource for those interested in anole morphology, development, physiology, systematics, and behavior (yes, even behavior!). Since the release of the original A. carolinensis draft genome in … Continue reading

What Can ‘Dead’ Anole Eggs Tell Us About Reptilian Development?
Anyone who has incubated reptile eggs knows that moisture is important. Without sufficient moisture, eggs quickly desiccate and shrivel beyond any chance of returning to a healthy, turgid state. Because of this, eggs must experience positive water balance during most … Continue reading

NSF DDIGs anoles
With the the deadline quickly approaching, the National Science Foundation‘s Doctoral Dissertation Improvement Grant (NSF DDIG) program is on the mind on many graduate student anologists (myself included). These grants provide significant funding (up to $15,000 this year) to graduate … Continue reading

Brown Anole Dewlapping at a Much Larger Predator: Why?
Most anole watchers have experienced the phenomenon of walking up to an anole and having it display. What good could come of displaying to a potential predator thousands of times more massive? In a perceptive experiment, Leal suggested that anoles … Continue reading

Thin Snakes Eat Big Anoles
The blunt-headed treesnake, Imantodes cenchoa, is renowned for its anolivory, but being a pencil thin snake, one might have thought that its carnage would be limited to the smaller members of anole nation. Not so, as two Natural History Notes … Continue reading

Variation in Habitat Use by Females with Different Back Patterns
In many species of anoles, females within a population exhibit sometimes strikingly different back patterns. A recent paper showed that there is interesting variation in the incidence of such variation: mainland and Lesser Antillean anoles exhibit it much more than … Continue reading
Reproductive Cycle of a High Elevation Colombian Anole
Brian Bock and colleagues, most at the Universidad de Antioquia in Medellin, Colombia, have published a series of papers on two populations of the high elevation anole, Anolis mariarum. The most recent in this series, just out in the journal … Continue reading

Monkey Eats Polychrus
Sure they’re cute, but in reality they are anole-killing machines. Well, maybe that’s an exaggeration, but at least some monkeys will eat just about anything, and I was once told of a capuchin that caught a large anole (A. frenatus), … Continue reading

Have You Seen Anoles Play Dead?
John Phillips and Kirsten Nicholson report in Herpetological Review (42:426-427) observations on A. laeviventris and A. cupreus. To wit: “Upon capture, the individuals struggled to escape the grasp of one of the authors (JGP), and then suddenly went limp without further … Continue reading

What’s All the Fuss About Dewlaps?
Anolis carolinensis from http://www.mascotissimo.com/wp-content/uploads/2008/02/anolis_carolinensis.jpg A few years ago, Richard Tokarz and colleagues conducted a series of studies in which he surgically disabled the dewlaps of some male A. sagrei and discovered that these functionally dewlapless lizards had no trouble holding … Continue reading

Dewlap Color, Gene Flow, Habitat Specialization, and Speciation: A Tale of Two Contact Zones
Despite all of the research on anole evolution conducted in the last 40 years, one important question still eludes us: how does speciation in anoles occur? This, of course, is of fundamental importance, because the great species richness of these … Continue reading
