|
Except for information about nesting activities, relatively little is known about the behavior or ecology of wild populations of northern diamondback terrapins. Diamondback terrapins are a cryptic species. Only females are seen on land during the early summer nesting season. Males never emerge onto land. What these turtles spend most of their time doing out in their salt marsh habitat is largely unknown. In order to gain more knowledge about their detailed movements, a sonic telemetry program was initiated at the Wetlands Institute during the summer of 2005. So far more than 40 female diamondback terrapins found in the vicinity of the Wetlands Institute in Stone Harbor, NJ, have been equipped with mobile transmitters (Vemco V9-2L-R04K coded pingers) and released back into the salt marsh. Nine stationary receivers (Vemco VR2), strategically placed throughout the marsh, pick up signals sent by the terrapin transmitters, allowing us to record their movements. Results so far show that there is considerable individual variation in the movements of different terrapins.
