Anolis Blood Work, “Normal” Levels

I was wondering if anyone has some good information, published or otherwise, on the normal values found within a blood sample for an anolis species?  We have been doing some sampling within our collection and are looking for something with which to compare our results.  We have Chamaeleolis porcus, barbatus, and chamaeleonides, as well as Anolis ricordi and smallwoodi.  The blood samples that we have taken are all from our porcus.  The only values that our vets currently have to compare to are those from a veiled chameleon, and being an old world species, I don’t know how well that translates to Anolis.  The calcium phosphorus ratio looks pretty close to normal, but the calcium level is almost three times as high as we expected.  Is this possibly normal for a lizard that is a snail specialist?  Any other information that you could give me would also be much appreciated. 

Thank you for any help,

Will

Anoles in the Blogosphere

It turns out that Anole Annals isn’t the only member of the WordPress.com stable that has a thing for our favorite lizard. While recently doing some tag surfing, we came across the following posts.

Catholic mom tells the gripping (or not) story of a green anole that went for a ride on the minivan windshield. You can probably guess the outcome, but the photos are nifty.

Anolis carolinensis Genome Paper Submitted

The long awaited paper describing the genome sequencing of Anolis carolinensis was submitted for publication on Thursday. Containing seven figures and with 50 authors, the paper is an epic step forward in our understanding of anole genetics. Stay posted for updates as the story develops.

Now There’s a Book Cover!

From the back cover: “Anolis lizards have been used in the development and testing of fundamental theories in ecology and evolution, and they have served as important models in behavioral ecology.” The cover photo is credited to Dan Warner.

Anole and Orchid Evolution–What Do They Have in Common?

Figure 1 from Pauw (2006)

Anton Pauw of Stellenbosch University in South Africa writes:

“I am reading Lizards in an Evolutionary Tree and find it fascinating to see how many parallels there are with my one of my study systems, oil-secreting orchids. While the anoles have differentiated across a series of niches provided by a plant, the orchids have differentiated across a series of niches provided by an animal. The orchids segregate the body of the shared pollinator among them so that each places its pollen on a unique segment of the oil-collecting bee. Orchid speciation generally involves shifts between bee species (with placement site conserved), but some speciation also occurs through shift in pollen placement site within the bee , so that sister species occupy for example the first and second segment of the front leg respectively.  Anyway, I thought that you too might find these parallels interesting, so I have attached two papers on the topic. I like the comparison of your Fig. 3.2 with Fig. 1 in the attached 2006 paper.”

The other paper is here. Incidentally,  apparently no one has posted a picture of an anole sitting on an orchid on the internet.

Statistics on the Commercial Trade of Anoles

Photo from http://www.petworldshop.com/

We’ve had a number of posts in recent months on the remarkable variety of anole species available in the pet trade (for example, here and here), particularly in the Europe. Another aspect of the pet trade, however, is the volume at which it occurs, and in this case, it is probably a few common species that make up the bulk of the trade. A recent paper in the Herpetological Journal explored reptile and amphibian commerce in Great Britain over a ten-year period from the mid-1990’s to mid-2000’s. The paper has some interesting points on various aspects of the dynamics of the trade, including how price has changed, the role of captive breeding, and other points. Anoles aren’t a central focus of this paper, but it does report that the price of anoles has increased over time, even after correcting for inflation: 26% in both A. carolinensis and A. sagrei, but only 4% in A. equestris.  This was about middle of the pack for lizard species surveyed. Some had become more expensive—more than 400% more in Parson’s chameleon—but about half the species had become cheaper, green iguanas dropping by 69% at the other extreme.

I summarized what I could learn about the anole trade in Lizards in an Evolutionary Tree. It isn’t much, but here’s what I had to say: From 1998–2002, more than 250,000 A. carolinensis and more than 100,000 A. sagrei were legally exported from the United States; in the same period, as many as 30,000 anoles of various species may have been imported into the U.S. Figures for imports into other countries are unavailable, but may be large because there are many reptile hobbyists in Europe. The United States is the only country likely to have much domestic trade in anoles, and these numbers, too, are great because many A. carolinensis and A. sagrei are captured and sold within the United States, not only for the pet trade, but also to laboratories, educational supply companies, and zoos. Data on the magnitude of this trade is scarce, but more than 250,000 anoles were collected in Florida in a four-year period in the early 1990s (this number may be a substantial underestimate because dealers were not required to report the number of the introduced A. sagrei and as a result, most did not do so.). in Louisiana, nearly a million A. carolinensis a year were collected in the mid-1990s, but that number has declined to around 350,000 per year in 2006, apparently as a result of declining demand, rather than shortage of anoles.

Nice Anole Videos

The website anolissen.nl has a collection of reasonably high quality anole videos, including one of Terry Ord’s behavior research, featured yesterday, as well as A. allisoni from Cuba fighting; many Cuban species displaying, including A. allogus (or was it A. ahli?) and A. mestrei; A. cuvieri displaying; A. punctatus displaying; a green anole (who can identify it?) eating a butterfly; and a bonus outgroup track of Polychrus acutirostris, as well as others.

Field Assistants Sought For Summer Anole Fieldwork in the Bahamas

Field Assistants (2-3) needed for field research on the behavior and ecology of the lizards Anolis sagrei and Leiocephalus carinatus on Great Abaco Island, Bahamas. The projects are part of a long-term study evaluating behavioral plasticity and its consequences on ecological and evolutionary processes. Assistants will be in charge of collecting focal observations and general ecological data. Duties include assisting in data collection, analyzing video recordings, habitat characterization, and data entry. Assistants must be flexible in their needs, comfortable living and working in close quarters, and able to work under hot and humid conditions. Assistants must enjoy watching and describing the behavior of animals for long periods of time, while working under relatively isolated conditions. Prior experience conducting fieldwork is desirable but not required. This can be a great opportunity for undergraduates with an interest in pursuing graduate studies in behavioral ecology or herpetology. An overview of the day-to-day activities related to this project can be found at

http://chipojolab.blogspot.com

Positions will run from 16 May to 13 June 2011. We offer a living stipend ($1,440/month), plus room & board and cost of transportation to the field-site. Field assistants will need to provide their own personal gear, including a backpack and life-jacket. Research will take place on relatively small islands, and short trips in a small boat are part of the daily activities. Email a cover letter, resume, and contact info for two (2) references to:

mleal@duke.edu

The review of applications will begin immediately.

Anolis Photo Presentation

Photo from http://www.dpchallenge.com/image.php?IMAGE_ID=18556

Just back from a talk on primate color evolution. I was gratified to see that the opening slide of the talk included a picture of an anole—didn’t expect that in a monkey talk! However, the image used was the one above. Anole seminar aficionados know that this is a no-no—this image has been used in more talks than is humanly imaginable! The reason is simple: when you Google (or Google Image) Anolis, this image is one of the first couple that pop up. And it’s seemingly a nice picture, so people tend to use it. All the time. But look more closely. This guy is not the Adonnis of the anole world. Rather, his schnozz is very beat up. This fellow should not be the poster child for the anole world. I had always assumed that he was a captive animal, who had rubbed his snout raw against an aquarium wall, as often happens. However, the recent post on fighting A. carolinensis illustrates that perhaps this guy is a fighter, not a lover, and bears the scars of his battles. In any case, a word to the wise: use another anole photo in your presentations.

The Proper Pronunciation of “Anole”

Dale Hoyt (dhoyt5@charter.net) asks the very reasonable question:

What is the proper pronunciation of “Anole”? Is it Ann-ol, An-ol-ee,or something else?
I get different answers when I consult online pronunciation guides, e.g.,
http://www.howjsay.com/index.php?word=anole&submit=Submit
or
http://www.merriam-webster.com/cgi-bin/audio.pl?anole001.wav=anole

Thoughts, anyone?
