We draw from our results a framework for cost-effective protection of long-lived species using satellite telemetry as a primary tool.Ĭitation: Maxwell SM, Breed GA, Nickel BA, Makanga-Bahouna J, Pemo-Makaya E, Parnell RJ, et al. This is the first comprehensive study on the internesting movements of solitary nesting olive ridley sea turtles, and it suggests the opportunity for tractable conservation measures for female nesting olive ridleys at this and other solitary nesting sites around the world. Though tagged individuals originated in Gabon, turtles were found in Congolese waters during greater than half of the internesting period (53.7 percent), highlighting the need for international cooperation and offering scientific support for a proposed transboundary park. Only 44.6 percent of high-density areas were found within the current park but the proposed transboundary park would incorporate 97.6 percent of high-density areas. Turtles remained largely within a 30 km radius from the original nesting site before departing for distant foraging grounds. We additionally determined confidence intervals surrounding home range calculations. These movements were analyzed in relation to current park boundaries and a proposed transboundary park between Gabon and the Republic of Congo, both created to reduce unintentional bycatch of sea turtles in marine fisheries.
We used satellite tracking and a switching state-space model to determine the internesting movements of olive ridley sea turtles ( Lepidochelys olivacea) (n = 18) in Central Africa during two breeding seasons (2007-08, 2008-09). To protect breeding adults, we require knowledge of animal movements, how movement relates to political boundaries, and our confidence in spatial analyses of movement. Tractable conservation measures for long-lived species require the intersection between protection of biologically relevant life history stages and a socioeconomically feasible setting.
