Hybridization Between Two Species of Garter Snakes
"Hybridization Between Two Species of Garter Snakes" by Hobart M. Smith is a scientific publication produced in the mid-20th century, specifically around the 1940s. This document discusses the genetic and morphological characteristics of two garter snake species: "Thamnophis radix" and "T. marciana", primarily within the context of southern Kansas. The focus of the book is on the hybridization between these two distinct species and the implications of their physical variations. In this publication, Smith details the distinguishing features of the two snake species, including their coloration and the structure of their lateral and dorsal stripes. He notes that while the two species maintain their distinct characteristics in various localities, there is a noticeable trend in "radix" individuals to exhibit traits more similar to those of "marciana". The author presents evidence of potential hybrids, exemplified by a particular specimen that displays intermediate characteristics between the two species. By examining various specimens and their attributes, Smith concludes that while hybridization occurs, the species typically retain their distinct identities in overlapping ranges.
