Invasive Anole Research In Florida

small brown anoleOne of the greatest threats to ecosystems is the continued introduction and spread of invasive species, which are commonly introduced to new areas by humans. Invasive species not only threaten nature preserves, but can harm commerce (such as zebra mussels damaging ships, or lionfish devastating fishing grounds) and pose a threat to public health by spreading disease (such as introduced rodents and mosquitoes). However, despite the problems caused by invasive species, we still know surprisingly little about what makes certain species successful in new ranges.

For my dissertation research in the Martin lab at the University of South Florida, I hope to identify the mechanisms that enable these species to survive and spread following an introduction. By identifying some of these mechanisms, we will be able to focus control efforts in a more effective manner by ascertaining which species have this potential. Specifically, I study Anolis sagrei, the brown anole, which is native to Cuba and the Bahamas, but is widespread across Florida where it has displaced the native green anole. My research aims to address if A. sagrei is able to be so successful in its introduced range in Florida because it changes the way it uses dietary resources as it invades new territory. The results of my study will not only fill a gap in the knowledge that we have on a common invasive species in Florida, but will also provide a stepping stone for future research on invasive species from other taxonomic groups.

The scientific community is no exception to having cope with budget cuts. Many labs that have traditionally depended on funding from federal agencies are finding money for research (especially ecological research) harder to come by. That is where the general public comes in. Crowd funding provides an opportunity for the general public to personally contribute to research projects and allows scientists to reach out and bridge the gap between the public and scientific communities. The support I receive from funders will be used to help me travel to different locations across the introduced range of A. sagrei in Florida and for sample processing at the University of South Florida. I will be sampling from sites close to the point of original introduction (Key Largo and Miami-Dade, FL), as well as sites where brown anoles have been reported for less than 20 years.

Geographic Variation In Body Size And Cells In Anolis Carolinensis

Think quick: how many states does A. carolinensis occur in naturally? And can you name them?

Evolution 2013: Anolologist Diet

As students of anole biology, we are interested in anoles’ ecological relationships, including what they eat (which apparently includes fingers!). But what do anolologists eat? At the Evolution 2013 meetings, ably covered by Jonathan Losos and Martha Munoz in a series of informative posts from the anole point of view, I was able to obtain photographic evidence. The foraging seems optimal.

Observations On Anolis Garmani In Florida

Editor’s Note: A report from the Sunshine State

I was asked to report on my most recent Anolis garmani exploits here in South Florida, So here goes. Remember, I’m not a scientist, or an author, just a funny old man with whiskers!

Thursday, June 27, 2013

An old friend had asked me to find him a few “Nice Green Anoles.” His intent, I believe, was to have me supply Anolis carolinensis for him to breed.

OOPS!!!

He received 1.2 young adult Anolis garmani!

My friend is handicapped & lives on a fixed income. He is also a very knowledgeable (& well known in certain circles) Herper. I thought he might enjoy these highly intelligent &, at times, PRECOCIOUS creatures!

SO!

I left work early, cuz I can do things like that! I know of several populations of Anolis garmani, from Southern Dade Co. to Northern Palm Beach Co., other than the colony at All-America Park. I decided to visit one in North Dade Co. ½ way between work & my friend’s house.

In the populations that I know of there are several types:

1) Green with a dark (½) tail & a red blotch on the top of the head

2) Green with powder blue ½ tail or more & blue bands. With or without the red blotch on head

Herpetological Publications

I am a retired businessman who is also an avocational herpetologist. I am currently disposing of a good portion of my library including many papers on Anolis. All at very reasonable prices if I do say so myself. If you would like to be on my mailing lists (e-mails weekly containing around fifty titles) you can e-mail me at tsinclair2@comcast.net

New Mexican Amber Anole

La Jornada en Linea just published an article on a new Mexican amber anole with information provided by paleontologist Francisco Riquelme. As discussed previously in AA‘s pages, this is only the second anole in amber from anywhere other than the Dominican Republic, the first, Anolis electrum, having been described by Skip Lazell in 1965. That specimen is very incomplete such that little can be said about its taxonomy or lifestyle. It will be interesting to learn more about this one.

Community Structure And Phylogeny Of Cuban Trunk-Ground Anoles

Two months ago, Masakado Kawata summarized the ongoing collaborative research program between Tohoku University in Japan, Habana University and the National Museum and Natural History of Cuba. The first fruit of this research has now been published in this month’s issue of Ecosphere (lead author Antonio Cádiz recently received his Ph.D. from Tohoku).

samplingThe paper is the result of an impressive field research program in which 12 species of Cuban trunk-ground anoles were studied at 34 sites throughout the breadth of Cuba. The abstract pasted below provides the nitty-gritties (and, of course, read the paper yourself), but here are some of the interesting take-home messages:

1. Three species–A. allogusA. homolechis, and A. sagrei–are widespread throughout Cuba, but the remainder have localized distributions.

2. Co-occurring species are a phylogenetically random subset of the clade, a result that obtains because of the combination of localized and widespread species that co-occur (four can occur in sympatry and five in an area).

3. Sympatric species are ecologically overdispersed, with species occupying different thermal microhabitats co-occurring.

4. Both A. allogus and A. jubar are paraphyletic with deeply divergent, geographically disjunct clades. The authors treat the clades as different species, and perhaps it is time for someone to formally describe them as such.

5. Anolis delafuentei–known, if I’m not mistaken, from a single individual–defied efforts to recollect it. Is this a real species? Is it extant?

Overall, this is an excellent study that could serve as model for the study of other species-rich ecomorph clades, both on Cuba (e.g., alutaceus group) and elsewhere.

Abstract:

Photos Of Aquatic Anoles Wanted For A Paper

Greetings! I’m writing with a request for all the photographically-inclined readers of Anole Annals. I’m in the process of finishing up a manuscript looking at the ecology and morphology of four species of Central American aquatic anoles – Anolis aquaticus, A. lionotus, A. oxylophus, and A. poecilopus. I would very much like to include a figure showing a good picture of each of these species. Sadly, my photographing skills are quite poor and I do not have any suitable images to include in this paper. I think the readers of this paper would be well-served to have a good image of each of the species examined and I would really like to include some pictures. Do any of you readers have an image or two of any of these species that you would care to share with me? You would, of course, be credited as the author of the photograph, and it would be published in a scientific study. If so, then please share your images with me at mmunoz@oeb.harvard.edu. Thank you!

Anole Talks At Herp Meetings

This year’s herp meetings will be held next week (July 10-15) in Albuquerque. Appropriately enough given the venue, it’s the Steve Poe Lab Show, with eight presentations emanating therefrom. Nonetheless, there are a number of other anole talks as well. Below is the list of the talks and below the fold, and attached as a pdf, are the abstracts.

AA is looking for reporters to provide eyewitness accounts of these talks. Many of the abstracts are cagey about what their actual findings are, no doubt out of paranoia and, more likely, an early abstract submission deadline combined with talks that are probably still being finalized. Those attending these talks, please let us know–any level of detail would be welcome!

We at AA obviously have a soft spot for those monstrously grotesque, yet winningly appealing giants of the anole world. Here’s a lovely picture that just passed through the tweet-o-sphere. Good pictures of knight anoles dewlapping are few and far between, and Ultra Violet kindly allowed us to reproduce it here.
