  1. Detailed movements of green sea turtles Roberta and Zyanya, from the nesting beach in Lechuguillas,Mexico to the foraging grounds off the Florida Keys. Data collected via satellite telemetry using The ARGOS Satellite System. Roberta Distance Traveled: 1429.65 km Mean Travel Speed: 0.362 km/hr Days in Transit: 61 days Last signal: April 18, 2001 Zyanya Distance Traveled: 984.55 km Mean Travel Speed: 0.631 km/hr Days in Transit: 73 days Last signal: March 22, 2001

  2. Estimated home range of the green sea turtle Roberta, as calculated using ArcView’s Extension, Animal Movement. This view represents home range as compared to land masses that comprise the Florida Keys and the Marquesas Keys. Total area of habitat utilization of this feeding ground by Roberta is approximately 2,745.63 sq km.

  3. Estimated home range of Roberta shown in overlay of benthic habitat. The habitat is primarily seagrass, 72.43% of categorized substrate covered by patchy or continuous seagrass beds.

  4. Estimated home range of the green sea turtle Zyanya, as calculated using ArcView’s Extension, Animal Movement. This view represents home range as compared to land masses that comprise the Florida Keys and the Marquesas Keys. Total area of habitat utilization of this feeding ground by Roberta is approximately 336.317 sq km.

  5. Estimated home range of Zyanya shown in overlay of benthic habitat. The habitat is primarily seagrass, 84.55% of categorized substrate covered by patchy or continuous seagrass beds.

  6. Roberta’s estimated home range utilization distribution, calculated using The Kernel Home Range Function of ArcView’s Animal Movement. Roberta’s defined home range is the area enclosed by the 95% polygon and is shaded dark green. The animals core area is located within the 50% utilization distribution and is shaded a lighter green.
