The U.S. Endangered Species Act prohibits the hunting of sea turtles and reduces incidental losses from activities such as shrimp trawling and development on beaches used for nesting. However, current monitoring does not provide enough information on sea turtle populations to evaluate the effectiveness of these protective measures. Sea Turtle Status and Trends reviews current methods for assessing sea turtle populations and finds that although counts of sea turtles are essential, more detailed information on sea turtle biology, such as survival rates and breeding patterns, is needed to predict and understand changes in populations in order to develop successful management and conservation plans.Sea turtlesSea turtlesEcologySea turtlesMigrationSea turtlesPopulation viability analysisUnited StatesSea turtlesMonitoringUnited StatesSea turtles.Sea turtlesEcology.Sea turtlesMigration.Sea turtlesPopulation viability analysisSea turtlesMonitoring597.928National Research Council (U.S.).Ocean Studies Board.National Research Council (U.S.).Division on Earth and Life Studies.MiAaPQMiAaPQMiAaPQBOOK9910963433003321Assessment of sea-turtle status and trends4367104UNINA
