NOLA ANOLE

On January 30, 2011

During a visit to New Orleans last month , I came across this little fellow.

Young male Anolis carolinensis, Washington Square, New Orleans, 30 December 2010

He was about 2 feet up on some broad-leaved plants planted around a tree in Washington Park, at the corner of Frenchmen and Royal Streets in Faubourg Marigny, just east of the French Quarter. Here’s an overview of the Square looking east, taken from about where the lizard was found.

Washington Square, New Orleans, 30 December 2010

I was actually a little surprised to find carolinensis, rather than sagrei. Anolis sagrei is well known as a good colonizer, both natural and introduced, and is now known from Florida, Texas, Georgia, and Louisiana, with stragglers reported as far north as Virginia. I was once given a tiny baby anole that was caught on a windowsill in Cambridge, Massachusetts (!) that I believe was this species; it had probably arrived as an egg in the soil of a houseplant.

Anolis Fangoria – Not for the Faint of Heart!

Fangoria - A quality publication and eductional tool for young children and for the young at heart.

I don’t know if it’s the cheap gore or the shock of something unexpected, but finding an anatomical oddity or bizarre mutant awakens the morbid curiosity impulse in me. Blame it on a childhood of being a closet reader of Fangoria and Rue Morgue, if you will. But several seasons in the field will put you face to face with some strange and bizarre reptile injuries. When I come across oddities, my first reaction is typically visceral, depending on the severity. My second reaction is curiosity. Where did the injury happen? What caused it to heal this way? I can’t say I ever have many answers, but the gory paraphernalia could fill a journal.

Anole Classics: Albert Schwartz (1974) on Geographic Variation in Anolis ricordii

By Rich Glor

In Classics from the Literature

Six years after publishing his impressive monograph on geographic variation in Anolis distichus, Schwartz published a similarly impressive monograph on geographic variation in Hispaniolan crown-giant anoles (Schwartz 1974). At the time this monograph was written, most authorities recognized a single polymorphic species of Hispaniola crown-giant anole with three subspecies: A. r. ricordii, A. r. baleatus, A. r. leberi, and A. r. barahonae (see my previous post on the spelling of ricordii if you’ve seen this name spelled with a single final “i” previously). However, as was the case with distichus, controversy was brewing before Schwartz’s monograph about whether these forms were best recognized at the specific or subspecific level and whether additional distinct forms had yet to be recognized within existing taxa.

Memorial Wall for Fallen Heroes of Natural History

Over at strange behaviors, Richard Conniff has posted an interesting memorial list:

The Wall of the Dead

The list sets out to honor naturalists who have lost their lives in the field or during other natural history pursuits. A lot of sad stories behind the names here, but a lot of epic ones too. I would bet that a great many of these fallen naturalists died doing what they loved best.

One of the names on the list is Ken Miyata, a young anole biologist who passed away in 1983. Ken was a student of Ernest Williams at Harvard’s Museum of Comparative Zoology in the late 70s (Ph.D. 1980), and he conducted fantastic work on anoles and other reptiles and amphibians, primarily in Ecuador. Although many of us probably know him for the mark he made on tropical herpetology during his brief career, Ken was much better known as a world-class fly fisherman, and it was that passion that ultimately killed him (see a brief retrospective here; see also these recent mentions of Ken by his old friends Jerry Coyne and Greg Mayer on the blog Why Evolution is True).

A name that’s missing from this wall is Preston Webster, another seminal anole biologist who died too young in a 1975 car crash. You can suggest additions to Conniff’s list in the comments of that blog, and he’ll add them. Does anyone who knew Webster want to put a few words on this site? I know very little about the man, but if there aren’t any takers, I’ll try to add him in a couple of days. I believe Webster was in the Dakotas when he died, and I don’t know if he was engaged in any ‘naturalist’s pursuits’ at the time (certainly not on anoles!). But this probably doesn’t matter – there are other great biologists on the list who died early in unrelated accidents.

There are several other herpetologists mentioned. Are there any other anole biologists missing from the list?

Hope for Haitian Biodiversity

In Notes from the Field

Nat Geo just posted an article on the rediscovery of six species of Haitian frogs thought to be extinct. This seemed like a good excuse to re-tell the story of the recent rediscovery of Anolis eugenegrahami from Haiti. This remarkable “semi-aquatic” anole, known from only a single, highly degraded locality, had not been seen in quite some time until an intrepid team of herpetologists set out to look for them. Read what they found here. Now, if only someone could find A. darlingtoni….

Anole Annals Trivia: Find the Anoles

In Anole Annals Trivia

I took this photograph last summer in the Sierra de Bahorucos of the Dominican Republic, not far from Polo. The first to answer the following three questions about this photo wins the respect of anole lovers around the world: (1) how many anoles are in this photo?, (2) what ecomorphs to they represent?, and (3) what species are they? First correct answers in the comments wins.

Sexual Dimorphism and Species Richness

By Jonathan Losos

On January 22, 2011

In Classics from the Literature

The figure above is a re-drawing from Schoener’s classic 1977 Biology of the Reptilia paper. Though “Competition and the Niche” has been widely cited, this figure, buried in the midst of the 102-page opus, has not gotten the attention it deserves. It shows that sexual size dimorphism in anoles is greatest on islands in which no other anole species are present and declines as function of the number of other anole species on an island. Anole community size is strongly correlated with island species richness, so this trend indicates that dimorphism and community richness are negatively related.

Why might this be?

More Introductions…

With the number of Florida’s exotics herp species already exceeding the number of native species, a couple more may be finding a new home in the Sunshine State.
Back in 2004 I was alerted to the existence of Anolis trinitatis at a Miami Beach hotel. I investigated the claim and sure enough they were there. I collected/removed 11 individuals (including juveniles) in 3 separate visits over a 6 month period. When I returned to the site in late 2006 they had begun renovation to the hotel and pool/garden area; the later being completely stripped of vegetation including the large Ficus trees and Pandanus in which the Anolis had been occupying. Subsequent visits to the site and surrounding area have not yielded any other animals and we think these have been extirpated.

More recently, 3 Anolis coelestinus have been captured in the vicinity of a reptile importer in Broward Co. I captured a large male 3 weeks ago, but did not see any other individuals in or around the area. We are uncertain if this species was released (or escaped) in large enough numbers to become established.

These and 75 other documented species will be discussed in a soon to be submitted paper, “A complete list of verified non-indigenous amphibians and reptiles in Florida through 2010: Outlining the invasion process and identifying invasion pathways and stages.”

Attached images are of anoles I collected in Florida.

Wipeout – Anolis lividus on the Volcanic Island of Montserrat

View of the defunct capital Plymouth as seen from the sea following dome collapse in January 2010

In 1493 Christopher Columbus named it after a mountain in northeastern Spain because he found the island to be as lush and green as the Catalonian province. It’s nicknamed the Emerald Isle of the Caribbean because its early Irish settlers found it reminiscent of their green coasts. But 500 years later most of the Lesser Antillean island of Montserrat has been anything but green. Its volcano became active again in 1995 and nearly two decades of periodic pyroclastic flows, lahars (mudflows with volcanic materials), as well as gas and ash venting have converted much of the island, especially the southern half, to a gray wasteland. The old capital of Plymouth, in fact, is covered under 40 feet of mud and ash. From the nearby town of Richmond Hill, which is about as close as you can get without being arrested (I’ve tried), you can see old sugar mills and three-story boulders that the volcano tossed all the way to Plymouth mixed together in a strange melange.
