Yellow-blotched map turtle
The yellow-blotched map turtle (''Graptemys flavimaculata''), or yellow-blotched sawback, is a species of turtle in the Emydidae family. It is part of the narrow-headed group of map turtles, and is endemic to the southern United States.
==Conservation status==
This species is listed as threatened under the US Endangered Species Act due to a recent decline. This can be attributed to a low reproductive frequency as compared with most other map turtles. A high level of nest mortality due to fish crow predation and river flooding are also attributed to endangerment. Unexpectedly high occurrences of nesting in shaded areas could possibly be attributed to human disturbances on and near sandbars, which raises mortality rates.〔Horne, B.D. et al. 2003. Reproductive and Nesting Ecology of the Yellow-blotched Map Turtle, ''Graptemys flavimaculata'': Implications for Conservation and Management. Copeia 2003 (4): 729-738.〕
Also, its habitat suffers from pollution and agricultural changes to water levels, affecting nesting beaches. "Turtle plinking", shooting turtles for casual target practice, kills significant portions of this endangered turtle's population each year.〔(''Graptemys flavimaculata'' at The World's Top 25 Most Endangered Turtles 2003. )〕
