My First Field Expedition

Miguel Landestoy's "Tank"

Hello everyone!  My name is Asa Conover, I am a student at Stuyvesant High School in New York, and this is my first post on AA. This summer I accompanied Martha Muñoz and Maureen Stimola on their trip to the Dominican Republic to investigate thermoregulation at different altitudes.  I did elementary fieldwork with anoles when I was 8. On a family trip to Naples, Florida, I caught a bunch with my hands. I was too sad to part with them when we left so my dad permitted me to take a few home (I apologize to any who frown upon this). At home we set up a proper terrarium with a small tree and a heat lamp. Shortly afterwards, as we were replacing the mulch, we found an egg. This was the first of many. The anoles bred rapidly and before they became too many to handle, we sent them all back to Florida with a neighbor.

Honey Holes and Rare Anoles

Saludos desede la República Dominicana!

Male Anolis fowleri

I’m just past the middle of a 6 week trip to the eastern half of Hispaniola to collect specimens and ecological data for geckos of the genus Sphaerodactylus as part of my thesis work.  I’m here for the most part with photographer, naturalist, and fellow adventurer Miguel Landestoy.  We’ve had a number of ups and downs already and I figured it is time to share some photos from one of our first nigths in the field when we stumbled upon a honey hole of rare anoles. Since Anolis fowleri is such a rarely seen and poorly known beast, here are some photos of a pair and their habitat. (sorry to keep this post short, but I’m here for geckos after all and am completely exhausted)

Juvenile Feeding Behavior

Over the past 6 weeks or so, I’ve been spending a lot of time caring for  Anolis carolinensis hatchlings as part of my common garden experiment. One of the most striking things that I’ve noticed about these growing lizards is how a hatchling’s hunting behavior changes over time.

Seven Anole Species Found at a Site on the Ecuador – Colombia Border

On the Tropical Herping website, Lucas Bustamante provides a report–accompanied by gorgeous photographs–of the seven species of anoles, as well as other reptiles and amphibians, found on a Tropical Herping field trip to Chical, a frontier site near the border of Ecuador and Colombia where the faunas of the Chocoan lowlands and the Andes meet. The diversity of species found on the trip was spectacular, but Bustamante aptly noted that the “anoles were the highlight.”

Jack Frost Nipping At My Embryos

My first thawed hatchling, Mr. Freeze, moments after emerging with the desire to rule the world (as soon as he got a little extra warmth from my finger)

Two weeks ago our building decided to test its emergency power generators.  They assured us there should be no problems (never the case) and that electronics plugged into emergency wall sockets shouldn’t have a disruption in power while others might experience small outages that evening.

We assumed our incubator was in the emergency socket and had little concern to think that any disruption to power would cause problems.  Needless to say, that was not the case.  There was a surge when the power came on and according to the repair tech it fried 2 boards… however when power was restored instead of returning to its preset temp, room temp, or even remaining off, it decided to turn on and drop the temp to freezing (or below) (we are unsure of the exact temp as the display board was one of the 2 that fried).  Everything inside was covered in frost and ice including the few remaining eggs I decided to spare from embryo extractions and allow to hatch for breeding next year.

Anole murder mystery, Part II

In a recent post Miguel Landestoy shared a phenomenal photo of an unfortunate Anolis whitemani that met an untimely end in the dunes of Salinas, in the Dominican Republic. This got me thinking about odd anole deaths that I have seen in the field. Sometimes the cause of death is quite clear. Perhaps a limb has been torn off, or the body otherwise bears the marks of predation. On other occasions, however, how the anole met its fate appears more elusive.

Anolis carolinensis in South Georgia

Anolis carolinensis, 15 September 2011. Residential Valdosta, Georgia

After living much of my life in the anole-saturated forests and neighborhoods of central Florida, somewhere beneath the Spanish Moss, I lived and worked in Anchorage, Alaska for four years. Other than the occasional wood frog, Rana sylvatica, my interactions with reptiles and amphibians were, of course, somewhat diminished… (Plenty of moose, though. Oh yes, plenty of moose. And dogs. Lots and lots of dogs.)

Anolis carolinensis, 02 August 2011. Residential Valdosta, Georgia.

This past summer I returned to the American southeast with my family — specifically to Valdosta, Georgia. Since returning, I’ve been struck by the density of Carolina green anoles and the lack of Cuban brown anoles, Anolis sagrei. In central Florida A. sagrei is ubiquitous these days. It’s hard to find a yard where they don’t dominate the trunk-ground area. In Valdosta, however, I have yet to positively identify a single Anolis sagrei (I’ve been told by locals they are here, but in isolated pockets). My little corner of south Georgia seems to be A. carolinensis territory in most every way, every day.

Indeed, I am seeing a strong and robust number of Carolina greens hanging out low to the ground, not just in the trunks and trunk-crowns. They’re on the bushes, they’re on the screens, they’re on the grass, and they’re even on the sidewalks and driveways. Low-riders, I call them — the Carolina greens riding the ground-level, juveniles and adults.

In a way, moving to Valdosta, Georgia feels a bit like time travel. It feels like central Florida circa the mid-1980s, minus the NASCAR fetish, back when I was a hairy little rugrat chasing green anoles through my Volusia county backyard while jamming Devo on my twelve-pound Sony cassette walkman. I’d nearly forgotten what Carolina greens are like without the presence of Cuban brown anoles and scattered Star Wars action figures in the grass… but what’s been most startling is the number of green anoles I’ve seen low-riding — basking on pavement, hanging out on concrete, scampering around fallen pine needles and leaves. Given their trunk-crown ecomorphology and the dominance of Cuban brown anoles in Florida, I wasn’t prepared to see so many Carolina greens surfing the ground. Is it a seasonal climate (heat) pattern? Not sure. Time will tell and I’ll keep watching.

It’s unlikely I’ll try to get these green anoles to bite my earlobes and wear them as jewelry like I did circa 1982 (the shame!), but I am enjoying this relative sense of time-travel. I also wonder when A. sagrei will make it up here in force — and push these greens back up into the trunk-crown, if ever.

Anolis carolinensis, 31 August 2011. Grand Bay WMA; Valdosta, Georgia

Zig First, Then Zag.

This female Anolis carolinensis has a tail that is kinked in a zig-zag fashion, starting from what seems to be the proximal autotomization point and continuing distally along the tail. The kinks are permanent. Running the tail between one’s fingers fails to smooth out the zig-zags. Have any anoleologists out there seen this growth pattern before? Any idea what might cause it? Additional photos and an x-ray are after the jump.

Predation on Anoles – A Revisit to the Turks and Caicos

Snake food! A young Anolis scriptus

To revisit an earlier post, here is some more information about the Southern Bahamas Anole, Anolis scriptus. In the Turks and Caicos Islands, this species is a crucial component of the terrestrial herpetofauana… as prey for other reptiles!

Readers of this blog might wish to avoid graphic details about anoles being eaten, but it is important to reflect on the role that these species play in ecosystems and energy cycles. In the Turks and Caicos, anoles are consumed by two endemic snakes, as well as curly-tailed lizards.

Amazing Anole Fight Caught on Film

Fights between male anoles in nature can get pretty serious.  A few dramatic anole fight videos have already been posted on-line, including some mentioned previously on anole annals ([1], [2]).  Recently, I posted photos from a fight we saw this summer on a rock along the Rio Bani between two males of A. d. ravitergum.  This was the most dramatic anole fight I’ve ever seen, with the males tumbling head over heels down a boulder while locked in combat.  The fight ended with one male skulking off and the other proudly displaying from atop the boulder.  Now, Shea Lambert has posted his video of the fight on YouTube (Shea aptly added background music from the classic video game Mortal Kombat).  This video was taken with a point and shoot digital camera, so the quality isn’t the greatest, but Shea did a great job capturing all of the acrobatics!  To quote Shea immediately after the fight: “That dark anole is a straight-up ninja.”
