Supplemental feeding and other anthropogenic threats to green turtles (Chelonia mydas) in the Canary Islands.

摘要: Green turtles are found in the waters of Canary Islands but little is known about ecology and anthropogenic pressures that threaten them. Our results have revealed juvenile green turtles, ranging curve carapace length from 26.9-81.0cm, regularly archipelago originate rookeries both eastern western Atlantic. Photo-identification satellite tracking showed high levels site fidelity to coastal foraging grounds associated with seagrass meadows, stable isotope analysis indicated animal-based omnivorous diets after settlement on continental shelf, no increase consumption macrophytes as grew. Most exhibited some blood biochemical markers a proteins fat. In addition, we determined organic inorganic pollutants. Supplemental feeding may also contribute explain prevalence hooking boat strikes brought wildlife rescue centers compared loggerhead turtles. Regulatory measures surveillance should be urgently implemented order improve status species archipelago.
