Posted by: CKing at Thu May 15 14:31:16 2008 [ Report Abuse ] [ Email Message ] [ Show All Posts by CKing ] Hi, Richard, I just noticed that I haven't paid close enough attention to the mtDNA cladograms of Rodriguez-Robles. Up to now, I have treated the Sierra Nevada snakes as presumptively large morph and that they form a single lineage. It turns out there are two sublineages within the Sierra Nevada subclade. Specifically, genetic data shows that the specimens from loc. #15, #17, #18, #19 and #26 (Tulare Co.) represent an older lineage than the sublineage which consists of Kern County dwarf boas plus the remaining Sierra Nevada snakes, including loc. #16. Based on genetic data, there is a chance that snakes from #15, #17, #18, and #19 and #26 (Tulare Co.) may be dwarf morph snakes. It may be worthwhile to have a look at these voucher specimens to verify their morphology. If they turn out to be small morph, then we may have both small morph and large morph boas living in the Sierra Nevada range. This sublineage (#15, #17, #18, #19 and #26) appears to have migrated northward along the Sierra Nevada at a slightly earlier time period than the boas from other localities that are large morph.
