Reptile & Amphibian Forums

1. I finally got around to actually READING the literature Fabian emailed some of us. One was a study on territorial relationships between male collareds on a dam site in Oklahoma (Arcadia Lake). Is that the paper to which you were referring in an earlier thread where I mentioned my interest in studying the relationship between collareds and manmade impoundments?

I know of several lakes now which have populations of collareds living on the riprap: In Oklahoma, Ft Cobb and Arcadia; in Arkansas (at least anecdotally), Bull Shoals and Norfork.

I find it interesting that the collareds managed to colonize Arcadia in less than five years after its impoundment, which I suppose is a testament to their dispersion capability (the area before the lake was there was not somewhere I'd expect to see a dense collared population).

Chris,
That's very interesting. They must move quick. I see them all the time along roads where there are rocks piled up on each side of the road from when they grade it. These rocks will be the only visible rocks in sight and were buried before the road grader knocked them to the side of the roads. I always wondered how long it took them to colonize these areas.
Thanks for the info.
Will
