>>Do you ever wonder if something like that was released there? How many "kinked up hatchlings" do you find in the wild? And how many Blonds do you find west of Fresno Creek? Prior to 1990, zero!
As for the first question, not really, for my part. I'm sure that they naturally disperse to close-by locales, and of course, you'd find fewer there if the phenotype was less fit for the environment, but you'd still find them on the fringe.
i.e. If the mutation is selected against west of their yellow limestone habitat, then that would explain seeing fewer. And, of course, no one was legally hunting TPRSs from 1977 until 1987. That could explain why people weren't seeing them there until 1990 with any regularity.
The remarkable thing is that it appears to be a recessive morph that is selected for and at least as equally fit as normals in that area.
