Guest post: Free-diver Laurent volunteering in St. Eustatius

During our fieldwork on St. Eustatius. Laurent helped as a volunteer to catch turtles. He also made some really nice video footage while free diving. His guest post: “Being a volunteer in a scientific mission is very simple : You just have to listen to the Project Leader, and you have to be available anytime, […]

All females? Experimental nest temperature assessments will show.

Sea turtle sex is not determined at the time of fertilization like in humans, it is set by the temperature level during nest incubation. 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. […]

New Publication shows Dutch Caribbean turtles migrate into risky waters

Lisa Becking (Wageningen University and IMARES) and I, together with Sea Turtle Conservation Bonaire (STCB) ; Mabel Nava, Sue Willis and Robert van Dam have shown in a recent publication that sea turtles who breed in Bonaire, Caribbean Netherlands, migrate great distances of up to 3500km to reach their foraging grounds across the Caribbean in 10 different countries.

2 times cake: 2 cool new papers! How to keep seagrass as happy as a clam?

This papers are the result of a successful collaboration between the University of Groningen, NIOZ and Radboud University, The Netherlands The first study by Els van der Zee et al. demonstrates that food web structure and complexity can be fundamentally shaped by 

Guest post: Jurjan’s research – turtle genomics

Within the Dutch Caribbean, green and hawksbill turtle rookeries and foraging grounds are found. Green and hawksbill turtles have been decimated by human exploitation and habitat degradation, calling for knowledge of population structure and demographic history. Here we investigate migration patterns in these highly migratory species and evaluate current population status. In other words: How many turtles were there […]
