Activity Patterns Among Head-Started Juvenile Alligator Snapping Turtles (Macrochelys Temminckii), Parker R. Golliglee
Activity Patterns Among Head-Started Juvenile Alligator Snapping Turtles (Macrochelys Temminckii), Parker R. Golliglee
MSU Graduate Theses
In contrast to many species of aquatic turtle, Alligator Snapping Turtles (Macrochelys temminckii) are putatively nocturnal. Data supporting this assertion are chiefly anecdotal, however, and two recent studies cast doubt on this generalization. Differences in activity patterns may be related to variability in temperature and photoperiod across the species’ range and may be influenced by ontogenetic changes, as well. To assess this, I equipped juvenile Alligator Snapping Turtles spanning a range of different ages with activity data loggers. I used 4-year-old turtles were to measure latitudinal differences in activity which were reared in hatchery ponds spanning the species’ …

Reintroduction Biology Of Head-Started Ornate Box Turtles, Eric R. Sievers
MSU Graduate Theses
The ornate box turtle (Terrapene ornata) is a prairie-dwelling species that has experienced population declines, especially near the northern edge of its range. In order to provide supporting research for a reintroduction program at the Upper Mississippi River National Wildlife and Fish Refuge in northwestern Illinois, I compared the relative success of different approaches to reintroduction. Specifically, I tested the null hypothesis that reintroduced turtles exhibited equal reintroduction success when, 1) released at a site that is known to support a viable ornate box turtle population, 2) ‘soft-released' in a fenced enclosure at a site where very few ornate box …
