Re: ID help from Tejon?

As for the Pits...stuff from the San Joaquin Valley side of the Tehachapis is ssp. catenifer . Snakes from around Lebec show definite influence of annectens ; whether one calls them that or catenifer x annectens intergrades is a matter of choice at this point. Glad to hear you figured out where the ...

Re: ID help from Tejon?

Your Ensatina looks like E. eschscholtzii eschscholtzii (Monterey), but they do not occur anywhere near Tejon Ranch. Are you sure of the locality?

Cheers,

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...

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).

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.

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....

Here's an example of a reproductive adult skiltonianus from the Tule River drainage, Tulare Co. at a site wh...

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.

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.
