Weight-Length Relationships in Thirteen Species of
Snakes in the Southeastern United States
A. Kaufman and J. Whitfield Gibbons
Regression equations of the form y = axb
were calculated for the relationship between body weight (y) and snout-vent
length (x) in 13 species of snakes from the southeastern United States.
All species except two (Crotalus horridus and Heterodon
platyrhinos) had slopes which were not significantly different from 3.00.
The effect of season on weight-length relationships was examined in four
species and found to be a significant factor in one (Natrix sipedon).
Sex was found to have a significant effect on the relationship in only
two species, C. horridus and Coluber constrictor.
Tail ratios (tail length/total length) were greater in males than in
females for adults of all species. The
percentage of the sample with broken tails in each species was positively
correlated with the mean tail ration for each species.
