Spatial ecology of green turtles 301


FIG. 1 Ninety-five percent minimum convex polygon (MCP) home ranges for each of nine individual green turtles Chelonia mydas tagged in Loango Bay, Republic of the Congo (Table 1, excluding individual D), derived from best daily locations at-sea. The 95% MCP for individual I is based on movements within foraging ground, clipped to 26 March 2013, the date this individual departed Loango Bay and started its migration south to Mussulo Bay, south of Luanda, Angola (Supplementary Figs 3 & 4).


TABLE 1 Metadata for each of the 10 green turtles Chelonia mydas tagged with satellite platform transmitter terminals (PTTs) in Loango Bay, Republic of the Congo. All individuals were released at Pointe Indienne.
