A half-century of demographic changes in a green turtle (Chelonia mydas) foraging aggregation during an era of seagrass declineNARA Subscribed
To understand the demographic responses of green turtles to seagrass decline, we examined a data set from study of a mixed-stock foraging aggregation of immature green turtles, Chelonia mydas, collected in Bermuda (32 o 18’N, − 64 o 46’W) over five decades. Average turtle size (SCL min ) and mass declined by 22.3% and 58.2%, respectively. Aggregation size structure shifted to smaller sizes and now consists of more small turtle...
Ecological regime shift drives declining growth rates of sea turtles throughout the West AtlanticNARA Subscribed
Somatic growth is an integrated, individual‐based response to environmental conditions, especially in ectotherms. Growth dynamics of large, mobile animals are particularly useful as bio‐indicators of environmental change at regional scales. We assembled growth rate data from throughout the West Atlantic for green turtles, Chelonia mydas , which are long‐lived, highly migratory, primarily herbivorous mega‐consumers that may mig...
Turtle groups or turtle soup: dispersal patterns of hawksbill turtles in the CaribbeanNARA Subscribed
Despite intense interest in conservation of marine turtles, spatial ecology during the oceanic juvenile phase remains relatively unknown. Here, we used mixed stock analysis and examination of oceanic drift to elucidate movements of hawksbill turtles ( Eretmochelys imbricata ) and address management implications within the Caribbean. Among samples collected from 92 neritic juvenile hawksbills in the Cayman Islands we detected 1...
