Abstract
Urbanization and other anthropogenic factors are often implicated in
turtle population declines, yet limited research on the natural history
of turtles in urban areas has been conducted. To assess the effects
of urbanization and to help develop proper conservation strategies for
Terrapene c. carolina (Eastern Box
Turtles), we conducted a mark-recapture study in the vicinity of Davidson,
NC, from 1999 to 2004. We made 354 turtle captures, 42 of which were
recapture events. We evaluated meristic characters, body condition,
activity patterns, population structure, and growth rates, and then
examined relationships among these variables and the amount of anthropogenically-modified
habitat within 100 m of each turtle’s collection location. Males
and females had different patterns of seasonal activity and body condition
indices. Growth rates decreased with turtle age and varied between developed
and forested habitats. More turtles over the age of 20 were found in
areas with extensive forest cover than in areas that were developed.
Although box turtles may persist in urbanized landscapes and may grow
more quickly there, they suffer higher mortality in these habitats compared
to forested landscapes.
