|
Kinosternon flavescens alamosae hirtipes integrum sonoriense Discrimination of turtles of the genus Kinosternon in the western United States and adjacent Mexico has been difficult because most taxonomically useful characters are size- or sex-dependent, or vary within species. Multivariate comparisons of continuous shell characteristics indicate that shell shape is highly correlated with body size, and therefore strongly allometric. Size-independent variation in shell shape can largely distinguish the various species, regardless of age. Size-independent variation was further analyzed in one species, Kinosternon sonoriense, and distinguished males, females, and juveniles. Unfortunately, carapace length, a frequently-used measure of standard size in turtles, was found to be strongly allometric with respect to size.
