| Abstract |
|
From 1969 through 2004, the turtle community of a 4.7 km section of the North Fork of the White River, Ozark County, Missouri was studied periodically. The Stinkpot, Sternotherus odoratus, was found in all years in low abundance. From 2005 through 2007, I continued this survey to determine the distribution and related parameters, movement patterns, population structure, and demographic parameters of S. odoratus within the research section. Distribution was similar from 1969 through 2006, with expansion to the terminal station of the research section in 2007. Turtle distribution was positively correlated with dense submerged patches of mud and rooted vegetation. Movement between captures from 2004 to 2007 averaged 198 m for males and 102 m for females, with a range of 0 m to 740 m. There was no difference between male and female carapace lengths or weight. There was a significant difference in male and female plastron lengths with females being larger. Sex ratios were slightly female biased but not significantly so. My study provides insight into the effects of land use change and habitat alteration on aquatic ecosystems. Continued habitat alteration, by affecting the behavior and abundance of species, may have consequences not only for S. odoratus but for the entire community.
