Anolis garmani, the Jamaican giant anole; Miami-Dade county, Florida (11 June 2016, Nikon D7100).

Every year, I try to get down to south Florida at least a couple of times to stomp around for non-native anoles and other lizards. To date, I’ve only managed to find and photograph three Jamaican giant anoles, Anolis garmani, in south Florida — three individuals over two specific visits to the Miami-Dade area. The first two were in June of 2016, and the third (and largest) was in August 2017. The garmani featured here was the second wee giant from that first visit.

I’d been anxious to photograph garmani for quite some time, and we (James Stroud, Eric-Alain Parker, and myself) were more than a little jazzed to get our hands on both of those garmanis.  A. garmani was quite high on my holy-grail list for south Florida non-natives, and, whereas this garmani may have been lacking in the “giant” aspect, it certainly didn’t lack in its color play. The lead image above through the following three profile shots were all taken within the span of two minutes (1:26pm through 1:28pm):

When we first spotted this particular wee giant biding its time in the plenty of existence, it was sporting the familiar bright emerald green:

Minutes later, in hand and not too thrilled about its potential lifespan outlook, the colors shifted quite dark…

…and then, more comfortably, back to a more-emerald green base:

Looking down from above, it had a fairly typical anole head from a central Floridian’s perspective…

But looking up from below? An extremely awesome speckled circus of contrast and patterning:

Yeah, this was one hell of a lizard to get to work with. Actually, all three of them were. I’ll save the bulk of photographs for the other two individuals for a future time, but for quick reference, here’s a single shot of each:

This is the first individual we found on June 2016:

Florida Greens and the Suprascapular Spot

Miami-Dade county, Florida; 18 March 2017

Miami-Dade county, Florida; 18 March 2017

After scampering about much of North America the past few decades, I once again live  in my hometown of Ormond Beach, Florida — on the northern edge of Volusia county. When I was a kid, back in the late 70s and early 80s, I spent much of my time tangling with and studying our local anoles. The Carolina greens (A. carolinensis) were dominant back then, covering our walls, windows, trees, and (sometimes by forced measure) our ear lobes. Every now and then I’d find a Cuban brown (A. sagrei) — usually around the shopping centers and strip malls. Nowadays, of course, that coin has flipped. The Carolina greens have moved back up into the higher foliage and the Cuban browns dominate our shrubs, walls, and windows.

I remember actually finding a Cuban brown anole on our property in 1984 or so. I was in 4th grade, drunk on Star Wars and lizards. I managed to catch the little non-native lizard and put it in my anole terrarium (a homemade wood-and-open-screen enclosure my dad and I built). I was in the habit of catching anoles (and the occasional snake), keeping and watching them for a day or two, and then releasing them back into the yard. Needless to say, the Carolina green already in the enclosure wasn’t too thrilled with his new roommate. Though guilt eventually kicked in the following day, I admit I was somewhat delighted by the defensive/discomfort color play of that poor Carolina green. Usually, they’d be cool, smooth emerald green with very little patterning… but distressed or riled up Carolina greens certainly know how to put on a good color and pattern show.

Soon enough, I released the Carolina green back into the yard and kept the Cuban brown for another day or two. This little moment of tension, however, leads me to the point of this post: the distress patterns of our local Carolina green anoles. More specifically, I’m interested in the presence of a supraspacular dark spot that shows up with some individuals. It’s a dark spot with light trim that sometimes appears just above and behind the front shoulder line — as seen in this particularly ornate individual photographed in Miami-Dade county on 18 March 2017:

This Miami-Dade individual really stuck out to me. It’s patterning was distinct. It was quite large. It had that supraspacular spot. Most notably, it was still wielding quite a bit of green. Could this be A. porcatus? Like many naturalist-lizard enthusiasts, I tend to catch myself up in the eternal cycle of porcatus-or-not? when I’m in south Florida. Heh. Nowadays,  my assumptions generally fall on the side of A. carolinensis unless I’m with somebody more in-the-know who can tell me differently with confidence; this hasn’t happened yet. Honestly, I have a hard time seeing a clear difference between the two. I’m glad I’m not alone.

Though distinct, this fabulously mottled Green wasn’t the only Green I’ve photographed with that supraspacular spot. Here’s an impressive male tangling with a Cuban brown anole in the Lower Keys of Monroe county, Florida, on 08 June 2007:

Further north, in my home territory, I’ve only noticed and photographed two individuals with that spot, albeit with less figure-ground contrast between the spot and the trim.

Please Help Me Identify Some Anoles and Other Cuban Lizards

Hello to everybody, I’m an italian naturalist that visited Cuba last December 2016.

I’m mainly a birder, but I like to give a name to all the creatures I meet. So, I’m going to post 20 pictures of lizards photographed in Cuba: for some I have hypotheses about the identification, but I need confirmation. For some others, I’m completely lost!
Can anybody help me??

Anole Adventures in the Cayman Islands

A sagrei on bluff - Cayman Brac NH

A. sagrei on Cayman Brac.

As part of an ongoing study of Anolis sagrei, recently posted about here with additional links therein, I had the pleasure of joining Anthony Geneva and Shea Lambert on a trip to Cayman Brac. We later met up with Graham Reynolds and his undergraduate student Amy Castle on Little Cayman, and closed the trip out with two days on Grand Cayman. Spending time on all three Cayman Islands was a real treat, in large part because of visually stunning anoles like Anolis conspersus and Anolis maynardi. These two species have received a lot of attention on Anole Annals. Rather than rewrite what’s already been written, I’ve decided just to share some pictures from the team. If you’d like to learn more, click on the species names above and explore to your heart’s content. Enjoy!

Dewlap Displays in Cuban Knight Anoles (A. equestris)

While exploring the grounds of Fairchild Tropical Botanical Gardens with Janson Jones this past weekend, we extremely fortunately happened upon a large adult male Cuban knight anole (A. equestris) in full displaying swing. Despite the fact that knight anoles have an impressively large dewlap, I have often found this to be a relatively rare event, as large crown-giant species tend to display less than other smaller and more active species. This individual was displaying at a height of ~15 m, just below the fronds of a large Royal Palm (Roystonea regia). We didn’t see any other neighboring knight anoles, so were unsure if this was a directed or passive display series. In all, this lizard performed perhaps 4-5 sets of dewlap displays (each comprising of 4-5 dewlap extensions) before stopping and retreating back into the canopy.

IMG_7793

Anoles typically follow a predictable and repeated pattern of display that gradually increases in intensity. Initially, and rather lethargically, an individual will nonchalantly raise its head and extend its dewlap without much extra effort (stage a); described below from Losos (2009).

Adapted from Losos (2009), which itself is adapted from Losos (1985). Aggressive behavior of A. marconoi showing three stages of increasing display intensity - note stage (c) include full body elevation alongside simultaneous tail and dewlap extensions.

This then escalates to include a slight body raise (stage b).

And ultimately results in a dramatic finale – in full display all limbs will be extended to raise both their body from the substrate (in this case the trunk of a palm tree) and elevate their tail (stage c). In the following picture you can see this final stage of displaying where intensity peaks – albeit in this individual with a regenerated (and rather stubby) tail.

Carrot Rock and the Endemic Anolis ernestwilliamsi

Carrot Rock, a small protrusion of British Virgin Island, links the southern end of Peter Island to the edge of the shelf constituting the Puerto Rico Bank. This <1.3 hectare, steeply sloped island is home to two endemic squamate species: the Carrot Rock Skink (Mabuya macleani) and Ernest Williams’ anole (Anolis ernestwilliamsi). This is a somewhat surprising situation, given the proximity of Carrot Rock to Peter Island (400m) and its recent connection to the latter by a breaking shoal (water depths are but 2-3 m between the two). Hence, separation of Carrot Rock was likely recent, occurring as early as the end of the Wisconsin Glaciation (~8000 yrs ago) or at nearly any point more recently, likely within the last 3000 years (suggested by Mayer and Lazell 2000).

Carrot Rock, British Virgin Islands. This 1.3 hectare island is steeply sloped, with an elevation of ~25 m asl and a very steep aspect on all sides. There are no landing areas and the island must be reached by swimming. Obtaining a beachhead and summiting require exertion and great care.

Nevertheless, morphological distinction has resulted in the specific epithets for these lizard species. The Carrot Rock Skink was described by frequent AA contributors Greg Mayer and Skip Lazell (Mayer and Lazell 2000) based on unique coloration and color pattern. The species was recognized in Blair Hedges and Caitlin Conn’s tome on West Indian skinks (Hedges and Conn 2012)–indeed, they used the node subtending M. macleani and other Virgin Island species as a calibration point. Recent analysis (Pinto-Sánchez et al. 2015) has suggested this species (along with other Virgin Island species), is (are) minimally divergent from the widespread M. sloanii complex. As the species was described based on morphology and appears to exhibit little genetic variation owing to a recent separation, species delimitation based on molecular data will surely point to collapsing these species and hence this latter finding is unsurprising.

Carrot rock is dominated by seagrape (Cocoloba uvifera) and the vine Stigmophyllon periplocifolium, with two large branching Pilosocereus royenii cacti on the crown. The majority of the anoles occur on the windward slope, where a few Cocoloba are sheltered enough to grow to heights of 1-3 meters.

Anolis ernestwilliamsi is very much a close relative of the widespread A. cristatellus. The endemic species is notable (and specifically recognized) largely for its increased lamellae number, color pattern, and apparently larger body size (Lazell 1983). It was described, again, by Skip, who is likely one of the few of us to have visited the island (and certainly the most frequent visitor). This description was published in Ernest Williams’ festschrift (Rhodin and Miyata 1983), in which, by my count, A. ernestwilliamsi is one of four nominate species named in honor of Ernest. As with the Carrot Rock Skink, molecular evidence suggests that A. ernestwilliamsi is minimally, or perhaps not at all, distinct from the widespread relative (A. cristatellus). Mitochondrial genetic analyses (Strickland et al., in review) demonstrate that A. ernestwilliamsi is nearly identical to many Puerto Rico Bank A. cristatellus haplotypes, suggesting a very recent maternal common ancestor (not surprising). Nuclear DNA has not yet, to my knowledge, been studied, likely owing to a lack of suitable (or available) DNA samples from the island. Concomitantly, several recent studies have demonstrated rapid evolution of key morphological traits in both Anolis sagrei (Stuart el al. 2014) and A. cristatellus (Winchell et al. 2016), including lamellae number, in response to presumed shifts in selection associated with either competitor species (Stuart et al. 2014) or non-natural substrate use (Winchell et al. 2016).

Turning back to Carrot Rock itself, we might suspect that selection differs on this small island, and that selection would act rapidly in the face of the (presumably; Lazell 2005) small effective population size. This shifting of phenotype, owing to either plasticity or underlying allelic shifts, represents the processes of genetic drift and selection acting on a small population. This is an expected scenario, but leads to the question of how we like to recognize lizard species. As I teach my Zoology students, and as we all know, this is a tricky question. Anolis ernestwilliamsi is phenotypically distinguishable from other populations of A. cristatellus (Lazell, 1983). Some (myself included) might argue that this limited morphological distinctiveness is insufficiently diagnostic of speciation given the lack of genetic distinctiveness and the overall degree of morphological variation in the species. Nonetheless, some (Dmi’el et al., 1997) have examined whether the population of A. ernestwilliamsi is behaviorally and physiologically adapted to an arid and exposed habitat, implying an adaptive evolutionary response resulting in phenotypic evolution despite very recent separation and genetic similarity. That these authors found a similar physiological response (evaporative water loss rates) and that Carrot Rock is really not ecologically different from Peter Island (or most of the coastal portions of the BVI), further support the idea that the population is not terribly distinct.

Male Anolis ernestwilliamsi. In a 1.5 hour survey around 1200h I counted only 3 adult males.

Male Anolis ernestwilliamsi. In a 1.5 hour survey around 1200h, I counted only 3 adult males.

With all of this in mind, and having recently been to Carrot Rock, I remain skeptical regarding the prospects for continued recognition of A. ernestwilliamsi, despite the desire to see Ernest continue to have an Anolis namesake. Nevertheless, this should not (and indeed, didn’t/doesn’t) diminish the joy of seeing this population grasp tenaciously to existence on this speck of beautiful land.

Battling Crested Anoles (A. cristatellus) in South Miami, FL

While out watching lizards last week with my undergraduate research assistant extraordinaire, Oliver Ljustina, and fellow SoFlo anole Ph.D. student Winter Beckles, we happened upon a pair of male crested anoles (Anolis cristatellus) ready to rumble! This is quite early – but not unheard of – in the season for the commencement of territorial disputes, so it was a surprise to see them locking horns so aggressively. This couple were battling fairly high in the tree, at approximately 3m.

Anyway, here are the pictures!

Reaching Safety

When somebody talks about roads crossing along natural forest, we could think about the perturbation this may cause to local fauna, especially in the Tropics. At least in Panama, wildlife crossings are not so popular in terms of design, deployment and monitoring. To my knowledge, the few existing ones are aerial and designed keeping in mind the crossing of monkeys or sloths for example. This issue came to my mind on the 3rd of November when I saw a Dactyloa insignis trying to cross an 8 m road traversing Santa Fe National Park, one of the pristine forest in central Panama.

It made three short attempts and looked clumsy when trying to run on the pavement puting him at risk of death, so we caught him and helped him reach the other side of the road.

Anole Photo Contest Is Back!

Lucas Bustamante-Enríquez’s Grand Prize-winning photo of A. chrysolepis from the 2013 contest (© Lucas M. Bustamante-Enríquez/TROPICAL HERPING)

We know you’ve all been waiting, so here it is! Anole Annals is pleased to announce the return of the Anole Photo Contest, 2015 edition! We’re closing in on November, which means it’s time to gather the best anole photographs for our 2016 calendar. As with previous contests, the goal is to identify 12 winning photos. The grand prize winner will have his/her photo featured on the front cover of the 2016 Anole Annals calendar, second place winner will have his/her photo featured on the back cover, and they’ll  both win a free calendar! (Check out the 2013 and 2012 winners). We’re a bit late getting things going this year, so get your photos in as soon as you can!

The rules: submit your photos (as many as you’d like) as email attachments to anoleannals@gmail.com. To make sure that your submissions arrive, please send an accompanying email without any attachments to confirm that we’ve received them. Photos must be at least 150 dpi and print to a size of 11 x 17 inches. If you are unsure how to resize your images, the simplest thing to do is to submit the raw image files produced by your digital camera (or if you must, a high quality scan of a printed image).  If you elect to alter your own images, don’t forget that it’s always better to resize than to resample. Images with watermarks or other digital alterations that extend beyond color correction, sharpening and other basic editing will not be accepted. We are not going to deal with formal copyright law and ask only your permission to use your image for the calendar and related content on Anole Annals (more specifically, by submitting your photos, you are agreeing to allow us to use them in the calendar). We, in turn, agree that your images will never be used without attribution and that we will not profit financially from their use (nobody is going to make any money from the sale of these calendars because they’ll be available directly from the vendor).

Please provide a short description of the photo that includes: (1) the species name, (2) the location where the photo was taken, and (3) any other relevant information. Twelve winning photos will be selected by readers of Anole Annals from a set of 28 finalists chosen by the editors of Anole Annals.  The grand prize winning and runner-up photos will be chosen by a panel of anole photography experts. Deadline for submission is November 21, 2015.

Good luck, and we look forward to seeing your submissions!

 

Conception Island, Bahamas Lizard Survey

Female A. sagrei

As part of our saga chasing Anolis sagrei around the Caribbean, we had the incredible fortune to visit the remote Conception Island Bank in the Bahamas. Conception Island and its associated small satellites are situated on their own bank, adjacent to Long Island which occupies a southeastern edge of the Great Bahamas Bank. Conception Bank and all its satellite islets are protected by the Bahamas National Trust as a National Park, and the bank is presently uninhabited though there is some history of human habitation in the past. Conception Island is quite small, totaling only 9 km by 2 km and has never been connected to any other island banks, meaning that the plants and animals here have almost certainly arrived via dispersal. Though located only 25 km ENE from the northern tip of Long Island, the 2400 m deep water and strong NW currents mean that the Conception Bank has a relatively depauperate terrestrial fauna owing to the vicissitudes of over-water dispersal. For example, in the latest comprehensive list of island herpetofaunal records, Long Island boasts 16 native extant species of reptiles and amphibians, relative to just five on the Conception Bank. Granted, this is potentially owing to lower sampling effort on Conception, as it is a remote, difficult, and expensive place to conduct extensive surveys. Indeed at least one record, that of the Bahamas Boa Chilabothrus strigilatus, is poorly documented and probably spurious.

An unusual dewlap color for A. sagrei

Alberto Puente-Rolon (UIPR-Arecibo), Anthony Geneva (Glor/Losos labs), Nick Herrmann (Losos Lab), and Kevin Aviles-Rodriguez (Kolbe/Revell labs) traveled with me to the Conception Bank aboard the Golden Bear out of Stella Maris, Long Island for two days in July 2015. Our goal was to sample Anolis sagrei from the bank, as well as generally conduct herpetofaunal surveys. We were particularly interested in verifying and attempting to build upon the last report of a herpetofaunal survey there (Franz and

Buckner 1998). While we expected Anolis sagrei to be present (it was), we also thought that the lack of a record for Anolis distichus might not stand up to our surveys. Alas, we checked multiple habitat types both day and night, from beach scrub to mature forests to mangroves and failed to turn up A. distichus. Though present on nearby Rum and San Salvador Banks (as well as Long Island), this species is curiously apparently absent from Conception.

Happily, we did find Anolis sagrei in abundance, and with some unusual features to boot. For one, the largest males are really quite large, tipping the scales at over 7 grams. Many males sported tall tail crests, and in the coastal scrub habitat, their yellowish dewlaps, combined with large size and tail crests, gave them an overall appearance very similar to Puerto Rican Crested Anoles (A. cristatellus). Interestingly, dewlaps in the forest appeared more traditionally sagrei-red, so we will see what our spectrometer and photographic data tell us about dewlap color variation on the bank. We will continue to update AA on our work with A. sagrei in the Bahamas.

Anolis equestris: Miami’s Favorite Cannibal

Anolis equestris with a smaller Anolis equestris in its jaws.

An Anolis equestris captures a smaller A. equestris in South Miami.

Cannibalism in Anolis equestris is nothing new, but that doesn’t make it any less surprising to witness! On a morning stroll in South Miami this past weekend, I noticed a flash of green movement on a tree. Upon closer inspection I realized there was a medium-large A. equestris with a smaller A. equestris wedged between its jaws. I hurried to snap a few photos with my wife’s phone, and while they aren’t Neal Losin-caliber (ha ha), I still wanted to share them with my favorite anole community!

Once I got too close, the A. equestris decided it was time to take its meal higher up the tree. An unsuspecting A. distichus saw the approaching A. equestris and began to dewlap enthusiastically. You can see the A. distichus near the top of the last photo. Enjoy!

Species ID from Bimini – A. sagrei or distichus?

After looking through my photos from my trip last week to Bimini in the Bahamas, I was disappointed when I realized that none of us seemed to have any pictures of Anolis distichus. Or maybe we did? Among all the typical sagrei-looking anole photos was this guy:

Anolis distichus or Anolis sagrei???

Anolis distichus or Anolis sagrei???

Without telling you why I thought this was a distichus, or why others I have asked are torn between distichus and sagrei, I am curious what people think. What species is this?

Help Identify a Large Costa Rican Anole

DSC00134

I was just curious if any one could help me identify an anole I found in central Costa rica, near San Ramon in the Alberto Manuel Brenese Biological Reserve. It appears to be a male, and I’m assuming in the Dactyloa genus. My guess would be the Dactyloa casildae, but I am family uncertain. It would be greatly appreciated if someone could help me out! Cheers and good health!

Some Sleepy Anoles from Costa Rica

I’m in southern Costa Rica doing field work with bats, but once an anole lover, always an anole lover so when I get a night off I like to go herping. Since everyone loves a sleeping anole (1, 2, 3, 4, 5, among others), I thought I’d share some photos that a friend and I took while wandering around at night. I’m not sure what the last one is; I’m guessing Anolis polylepis (we’re at 1100m at the Las Cruces Biological Station and it was sleeping about 1m above the ground).

What’s the Best Camera for Photographing Lizards in the Field?

Hi Everyone, I am in the market for a new field camera. Looking for something durable, portable, and that can take great shots of anoles and their dewlaps (so good at close-ups, but not necessarily a macro lens). I currently use a Nikon D5100 SLR, but it is fairly bulky and fragile. What sorts of cameras and camera systems do you use in the field? Thanks!

Observations of Anolis allisoni on the Island of Roatan, Honduras

Marine biologist (and occasional anolologist) James Hewlett, a Professor at Finger Lakes Community College, shared a few photos with me from his recent trip to Roatan island. Jim was in Roatan to do reef surveys, but in the few moments he wasn’t under the water, he was out looking for anoles. He found numerous Anolis allisoni, even at midday, when it was stifling hot. Anolis allisoni are known to be quite abundant on this island, and do exhibit quite a bit of variation in coloration.

Anolis allisoni is not the only anole found on Roatan. It probably comes as no surprise, but the brown anole (A. sagrei) has made its way to the island. Jim did not observe any brown anoles on his recent trip, but I reckon they’re still there and doing just fine. Despite his best efforts, Jim was unable to find the other native Roatan anole, Anolis roatanensis. A few years ago, Jonathan Losos was also unable to spot this creature on his first day of herping, but eventually did find it (see photo in comments below) by visiting more forested areas on the island. If you visit Roatan and manage to spot this species, please do share. We’d love to see more photographs of it.

In the meanwhile, here are some of Jim’s images:

Finding the “Rare” Anolis duellmani

Like many quests to find rare herps, this is a story of courage, persistence, and strength. Just kidding; it was a piece of cake.

Anolis duellmani was described by Fitch and Henderson (1973) based on four specimens from the southern slope of the Volcán San Martín Tuxtla, Veracruz, Mexico. Even though the phylogenetic position of A. duellmani is uncertain, no additional morphological variation had been described for the species. As part of a major effort led by Dr. Adrián Nieto-Montes de Oca and Dr. Steven Poe to untangle the systematics of Mesoamerican anoles, Israel Solano-Zavaleta, Levi N. Gray, and I went to Los Tuxtlas to search for the elusive species.
