Taxonomy / Phylogeny
I read an article on the many cages in North American Colubrid Snake classifications. It never went into specifics and I'm having a bit of trouble finding anything on the subject.
My questions are, what are the causes of these changes between genus's / tribes of the sub family colubrinae? Lampropeltis, Coelognathus, Pituophis, Pantherophis, specifically.
Also what are the phenotypic differences? Generally I can make a solid guess off previous experience but you could line up a bull snake, pine snake, fox snake, rat snake etc. and maybe even a corn snake and I couldn't tell you the differences. (Besides possible color in certain species)
Any links would be helpful too.
