Abstract (Summary)

Urban coastal development has led to major changes in ocean temperatures and habitats along the coastline. These alterations particularly affect coastal ectothermic marine species, such as green sea turtles, Chelonia mydas. This species has been observed north of their geographical range in the eastern Pacific; inhabiting a river and estuary that both have anthropogenically-altered water temperatures and habitats. Passive and active acoustic telemetry was used to determine how green sea turtle movements and habitat use were affected by these anthropogenically-altered sites. Turtles used both sites during the summer months, while during the winter, individuals selected for areas where warm water was discharged from power plants into the river. Further, turtles tracked in the larger river used more area than those tracked in the smaller estuary. Turtles selected habitats associated with manmade structures at both sites and eelgrass beds within the estuary to potentially rest and forage upon.
