Anole Photo Contest: Still Time To Enter

On October 21, 2013

Last year’s winner, Anolis allisoni by Steven De Decker and Tess Driessens

We’ve gotten a fabulous set of entries already, but rumor has is that there still might be room for an even better one. So get your photos entered before the end-of-the-month deadline. And don’t forget the grand prize: a spiffy Anolis watch of the ecomorph of your choice! Enter today!

The rules: please submit photos (as many as you’d like) as attachments to anoleannals@gmail.com. To ensure that submissions with large attachments arrive, it’s a good idea to send an accompanying e-mail without any attachments that seeks confirmation of the photo’s receipt. Photos must be at least 150 dpi and print to a size of 11 x 17 inches. If you do not have experience resizing and color-correcting your images, the simplest thing to do is to submit the raw image files produced by your digital camera (or, for the luddites, a high quality digital scan of a printed image). If you elect to alter your own images, don’t forget that its 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. 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 1, 2013.

Biodiversity Of The Lesser Antilles Conference Volume

By Jonathan Losos

On October 19, 2013

In New Research

A conference on the fauna and flora of the “Petite Antilles” was held in Martinique in 2010 and the resulting conference volume has just appeared and is downloadable. The papers are many and varied, covering all manner of organism and topics spanning a wide range of topics. I’d give a full report on the papers, but…most are in French. Of most interest to our audience is a paper from Roger Thorpe’s reporting further studies on contact zones between divergent A. roquet lineages on Martinique (we previously discussed what was formerly their most recent study). In addition, the Bobs Powell and Henderson, along with Gad Perry and others, have a paper on introduced species of the Lesser Ants, Michel Breuil has one on sphaeros, and there are a number of others of interest. The full Table of Contents is below.

Egg-Laying Biology Of The Green Anole

By Jonathan Losos

On October 18, 2013

In New Research

The egg-laying biology of anoles is surprisingly little studied. Where do they lay their eggs? How often? Inquiring minds needs to know. And now a team of Japanese scientists led by Mitsuhido Toda has taken a small step to answer these questions.

Working with green anoles introduced to islands near Japan, the researchers brought ten females into the lab, amply fed and watered them, and saw where and how often they laid eggs. The lizards were brought into the lab in April and the first egg was laid in late May. Egg production increased until a peak in mid-August and ended in late October. Over the course of the season, females laid an average of 13.7 eggs. At the peak in August, females were averaging almost an egg a week.

Perhaps the most interesting part of the study was the cage in which the females were kept, which had a variety of available sites, including a potted fern and pots with wet and dry soil all at ground level, and another set of pots at a meter. Females strongly preferred the low-down pots to the high ones, and the pots with the ferns to those without. Among eggs laid in fern-less pots, all were in the wet soil and none in the dry soil. In the pots with ferns, eggs were often laid in the cup-shaped part of the plant in the center of the pot or between the eggs; eggs laid in the soil were from 0-50 mm below the surface, averaging 17 mm deep.

This research is part of a greater effort to learn the natural history of the green anole so as to eradicate it from the Japanese islands, where it is apparently having a devastating effect on the endemic insect fauna [1,2]. The researchers suggest that eradication efforts may be most useful in April, before the egg-laying season begins, and also suggest the development of artificial egg-laying sites, from which eggs can be harvested before they hatch.

Anole Annals is very sorry to learn of the passing of AA contributor Chad Watkins. Chad, a graduate student at the University of Texas-Arlington , was killed in a car crash October 8th in Dallas. Chad’s research was on the occurrence of transposable elements in Hox genes in Anolis carolinensis. We reported on his fascinating talk on this topic at the 2011 Evolution meetings, and Chad himself posted on some eggs that survived freezing in an incubator mishap. Rest in peace, Chad Watkins.

Predation On Anolis Sagrei By A Juvenile Southern Black Racer

By Ambika Kamath

In Introduced Anoles, Natural History Observations, Notes from the Field

I’m a big fan of predation events, and after two and a half months of working with Sitana in a site bizarrely devoid of predators, I had high hopes for Miami. I was not disappointed, and on my second day, had the chance to watch this snake capture and eat a female Anolis sagrei. This happened in the grounds of the Florida International University, Biscayne Bay Campus, where I was collecting some preliminary data on A. sagrei territory overlap. The photo is from relatively early in the lizard consumption process, before the snake (a Southern Black Racer, Coluber constrictor priapus) turned the lizard around and swallowed it head first.

I initially thought the anole was A. distichus, which are abundant in the area where I saw the snake. On seeing that it was in fact A. sagrei, I realised that I might have unwittingly played a role in the lizard’s demise. I had in fact been trying to catch a female A. sagrei in the vicinity myself, and must have chased her right into the grasp of this snake! I like to think of the situation as my having facilitated the snake’s successful capture, and not as being out-lizarded by a baby snake, but I know I’m just deluding myself…

Thanks to Gabe Gartner and James Stroud for identifying the snake.

Hueyfest A Great Success

A week ago Friday, 60 people gathered at the Burke Museum in Seattle to celebrate the career of Ray Huey. And what a career it’s been: thermal ecophysiology, comparative methods development, rapid evolution in Drosophila, effects of global warming on ectotherms, and much, much more.

And we heard all about it, and then some, in the eight talks that filled the day’s proceedings. The presentations were many and varied, but all had one theme: the important role Ray has played not only in the development of important ideas in science, but in the lives of the people with whom he has interacted. Here’s a few highlights:

Paul Hertz, who has worked with Ray since they were graduate students, reflected on Ray then and now

The “Rediscovery” Of Anolis Proboscis, And The Evolution Of A Viral Internet News Story

By Luke Mahler

On October 11, 2013

In Anoles and Anolologists in the News

If you work on Anolis lizards, there’s a good chance you’ve been asked about the recent rediscovery of the long-thought-to-be-extinct “Pinocchio Anole” within the last week. As Anole Annals reported on October 7, this story has hit the big time. After being featured on the Huffington Post, the tale of this rediscovery went viral, receiving extensive news coverage worldwide.

The catch, as most Anole Annals readers are doubtless aware, is that the Pinocchio Anole wasn’t just recently rediscovered. It was rediscovered in 2005, and has since been the subject of field studies resulting in no fewer than five published works (six if you count “Finding Anolis proboscis,” Steve Poe’s 2010 Anolis Newsletter article about finding Anolis proboscis).

What gives? How can the central claim of such a major scientific news item be fundamentally incorrect?

I propose the following hypothesis: This story evolved to its current state by good old-fashioned natural selection. I think that an initially accurate web story was repeatedly and imperfectly replicated, and that as the story was picked up by increasingly larger news outlets, important details were lost or altered during transcription (perhaps selectively, since discovery makes good copy), resulting in the evolution of an incorrect news item.

If I have things right (it’s possible I don’t know all the details), the story started with an informational advertisement from the ecotourism company Destination Ecuador.

If you read that article, it’s pretty accurate with the potential exception of a single use of the word “re-discovery” to describe the event during which the Tropical Herping team found Anolis proboscis. The use of that word is admittedly a little strange and perhaps a bit unwise, but the article makes it very clear that the actual rediscovery of the species took place in 2005, and describes a successful scientific expedition to study the species in the wild in 2010. To me the point of this article is “with our ecotourism company, you can have a chance to travel with experts to see a weird, rare, recently-rediscovered lizard species.”

Next comes an article by Douglas Main on livescience.com, which appears to be the original source of the viral news item. If you read the LiveScience article, it’s worded in a way that tells a narrative of very recent rediscovery (which is not really true) without ever explicitly stating it.

Brown Anole At Bermuda International Airport?

Mark Outerbridge recently posted this photo in a comment, writing: “This photo of an anole hatchling was taken (via cell phone, hence the poor quality) by a member of the public in the departure lounge at the Bermuda international airport. Could it be a brown anole?”

We’ve already reported on brownies in Bermuda, but who would have thought they were going in on commercial flights? Or maybe they’re heading home? Is this a brown anole? Could it be Anolis grahami or some other species?

In the last year or two, we’ve seen a number of documentaries on Cuban anoles, and here’s another, a 12-minute piece featuring A. equestris, A. vermiculatus, A. ahli (I think), A. sagrei, A. angusticeps, and others. Worth watching, just for the closing line, “There are over 300 anole species in the Caribbean, making the Anolis lizard one of the planet’s most diverse and evolutionarily significant animals.”
