Between May 2005 and March 2006, 10 alligator snapping turtles (Macrochelys temminckii) were radio tagged and tracked, with 8 turtles captured at two sites, and two turtles obtained from professional trappers. Three of the 10 turtles were translocated to a site not known to harbor Macrochelys (Red River National Wildlife Refuge), while the remainder were tracked in their native environment (Cross Lake). All radio tagged turtles carried thermal dataloggers, whose data collection was staggered to allow for a season’s worth of recording time. Turtle movement was analyzed and compared between native versus non-native turtles, age class, and thermal preference.
