Re: A fine find

Cool finds. These look like Black-bellied Slender Salamanders (Batrachoseps nigriventris).

Re: A sense of place in herp photos

[quote="aliceinwl"]A few of mine, I've posted these before, but not since the crash: http://farm3.static.flickr.com/2656/4159864238_190f607757_z.jpg I appreciate that these shots take a lot of work, and often just don't work. But this Uma shot is just exceptional. How did you light the scene? Cheers...

That is an awesome shot. It's neat to see so many recognizable features from a different vantage point. Very cool stuff.

Re: Herp-a-day (pt II)

In keeping with an anuran, if not “toad” theme, here’s a Spotted Chirping Frog, Eleutherodactylus (= Syrrhophus) guttilatus from the Big Bend region of Texas.

Here's a starting point...you can download various reports and publications as pdf's. There should be plenty here to keep you busy.

Re: Trying to find another Rubber Boa population

It was great, Carlo and I brought six pieces of carpet up there, but it needs a lot more! I won't be able to make it back up there this weekend it turns out because of the reptile show in Sacramento (I'm going to be there both days). Also, I need to find some more AC that can be hauled up there... ...

Re: SoCal Endangered species herping, part 4

Excellent, Sam. Lots of cool stuff I didn't know, especially the bit about the ant diet and the fidelity of ants to specific trails. I would imagine that any sort of anthropogenic interference with those trails might muck things up for the toads as well.

Thanks for that clarification. I would love to see big males reacting to elevated forearms and closed fists!

Re: Nevada combat in Crotalus lutosus

Bryan:

That's a really neat observation. So what do you make of the timing (mid-late July) of this behavior? Are males already guarding females prior to fall breeding?

Re: Plestiodon skiltonianus in Southern Sierra Nevada (??)

Okay...I shared Jonathan's Hwy 155 blue-tailed skink pic with Jon Richmond (who has worked extensively with western skinks), and as they say in the NFL, "Upon further review..." we agree that it is in fact a gilberti ...not a skiltonianus as I originally called it. Jonathan's skink was taken at fair...

Re: Plestiodon skiltonianus in Southern Sierra Nevada (??)

Correct me if I'm wrong, but I thought gilberti in some locations show up with blue tails as well, including in their upper range of the Greenhorns. Yes? No? There is a transition from blue-tailed juvenile gilberti ( E. g. gilberti ) to pink-tailed juvs ( E. g. rubricaudatus ) somewhere in the vici...

Re: Plestiodon skiltonianus in Southern Sierra Nevada (??)

Your skink is a skiltonianus . The juvenile gilberti in that area are reliably pink-tailed. What makes ID-ing your animal tricky is that the striping does not extend very far onto the tail, a feature diagnostic for gilberti . However, there are parts of the range where that is not terribly reliable....

Will: There really are skiltonianus in the Greenhorns and on Breckenridge Mtn. There are mis-ID'd animals in collections, but mostly it is juvenile gilberti that are labeled as skiltonianus . Here's an example of a reproductive adult skiltonianus from the Tule River drainage, Tulare Co. at a site wh...

Re: Cleaning up P regilla complex in database

For the record, I'm not sure I want to endorse the species split until more info from contact zones is obtained with clearer indication of where the splits occur (if they are in fact valid) but I think it is better to stick to SSAR simply for conformity to the chosen taxonomy standard. You would el...

Will:

Animals from all of the areas you mentioned look pretty much like this, although the blue tail color fades to a blue-gray in older lizards. This is one from the Kern Plateau.
