Our in-water survey of sea turtles and their habitats in St. Eustatius (a.k.a. “Statia”) was very successful. We aimed to collect data to analyse the habitat use and population connectivity of green and hawksbill turtles as part of a larger NWO research program encompassing the 6 Dutch Caribbean Islands. Together with STENAPA (National Park authority of St Eustatius) and volunteers, and support [...]

For this we used the inter-nesting durations of the first green turtles tracks that were reported for Zeelandia beach, St. Eustatius. Equipped with a turtle box, satellite transmitters, our red [...]

Recently for some small island rookeries througout the Caribbean researchers reported a shift towards a more female dominated hatchlings/populations as nest temperatures slightly increased in these areas (warmer beaches result in female turtles). At St. [...]
