| Abstract |
|
This paper consists of two parts. The first section contains a literature review of what is currently known about sea turtle migration and navigation. Included are discussions of field experiments and molecular work, as well as suggestions for future research in these areas. A variety of aspects are covered, including the orientation behavior of hatchling sea turtles, the “lost year” of juveniles, behavior in foraging grounds, and adult sea turtle migration behavior. I hope that this will serve to bring together the large amount of literature in this area, which has generally been rather scattered and disjunct. I found that by bringing all this literature together and making it into a more cohesive unit, I was able to gain more of a general understanding of the field and of what still needs to be done. The second section of this paper concerns a study conducted on the diamondback terrapin (Malaclemys terrapin) population in Jamaica Bay, New York. This study took place from early May through early September, 2001. The diamondback terrapin is an organism whose ecology and life history parallel those of sea turtles in several ways. First, terrapins can tolerate a wide variety of salinities, and are found in coastal areas in up to full strength seawater. Diamondback terrapins may also share nearshore foraging habitats with sea turtles in many areas, and both terrapins and more marine turtles lay their eggs on land and exhibit at least some degree of nesting beach homing. I considered the M. terrapin population in Jamaica Bay, New York, which historically has been one of the largest populations of this species in New York State and perhaps in the entire Northeastern United States, to present an interesting system in which to study issues of migration and navigation without the large-scale satellite telemetry studies required for sea turtles. Little is known about diamondback terrapins in open water, especially in the Northeast, as most research has focused on nesting areas. I hope to introduce the reader to this study system, relate the results of this research, as well a present some discussion of the challenges of working in this area and possible future research goals.
