Hawaiian Nesting Range Shift Offers Rare Learning Opportunity

Green turtles are among the most iconic species in the Hawaiian Islands, and they have been the subject of scientific study for more than four decades. Extensive research on the Hawaiian green turtle population has enabled us to observe changes in Hawaiian green turtle nesting distribution that may suggest the foundation of a new, distinct nesting population, thus offering a unique learning opportunity.

Sea Turtle Nesting Expansion into Peru Brings New Management Challenges

Before 2000, there had been only a single published account of sea turtle nesting in Peru. The prevailing notion was that Peru is too far south—too cold—for successful sea turtle nesting. Thanks to the efforts of ecOceanica, we now know that nesting seems to be on the rise along Peru’s coast.

Rising Seas: Addressing Eroding Habitats on St. Catherines Island, Georgia

On St. Catherines Island, Georgia (U.S.A.), three geologists involved in sea turtle conservation—have been documenting the deterioration of sea turtle nesting habitat caused by sea-level rise since 1998. The extreme shoreline changes on St. Catherines Island produce difficult conditions for nesting loggerhead sea turtles and challenge conservation efforts; however, these conditions also create an opportunity to develop, evaluate, and optimize conservation methods on this sentinel island.

Managing Moving Targets: Identifying and Responding to Sea Turtle Nesting Range Shifts

Change is nothing new to sea turtles. They have inhabited the Earth for many millions of years, persisting and evolving through the continuous changes in distribution of land and sea, climate, ocean currents, and sea level that have defined their world. First appearing in the fossil record 110 million years ago during the Early Cretaceous, sea turtles have shown remarkable resilience in adapting to environmental changes throughout their history.

The 11 Most Threatened Sea Turtle Populations

The following list was published in The State of the World's Sea Turtles Report Vol. 7 in 2012 and identifies the 11 most threatened sea turtle populations in the world. This analysis was made possible by the priority-setting efforts of the Burning Issues (BI) Working Group of the IUCN Marine Turtle Specialist Group, which created a framework for delineating sea turtle populations globally (RMU's) and then evaluated, compared, and organized sea turtle RMU's within the context of a conservation "priorities portfolio".
