A Preliminary Report on the Examination of Small Mammal Census MethodsTerrestrial Activity in Aquatic Turtles
H. Bennett, J. Whitfield Gibbons, and J. Christian Franson
Individuals of three species of aquatic turtles (Kinosternon
subrubrum, Pseudemys scripta and Deirochelys reticularia)
were captured in drift fences after emigrating from a Carolina bay in South
Carolina. Each turtle was tagged
with Tantalum-182 pins and relocated with a portable beta-gamma survey meter.
Turtles were found burrowed at various depths (1-22 cm) below the surface
and up to 600 m from the aquatic environment.
The number of days an individual was followed and the land distance moved
were significantly correlated. Temporary
emigration and shallow burrowing by K. subrubrum are possibly
mechanisms for predator avoidance in that individuals which concentrate in a
drying-up aquatic area are selected against.
