New discoveries on relationships between host corals, crabs and christmas tree worms

A series of recent surveys worked to highlight the important relationships between host corals, crabs and christmas tree worms. Studies were conducted off the coasts of Sint Eustatius, Curaçao and Bonaire. Understanding the relationship between reef inhabitants and their host corals could be critical in designing conservation efforts for reefs into the future.

Get to Know Bonaire’s Seaweeds

The 2019 Naturalis Biodiversity Center and ANEMOON Foundation expeditions worked, among other things, to catalog the wide variety of seaweeds off the coast of Bonaire. From this and previous reports, nearly 250 species were identified and the most common were highlighted in the “Common Seaweeds of Bonaire” ID cards, now available for free download from the Dutch Caribbean Biodiversity Database.

Protecting Saba’s Painted Black Iguanas

New research describes a unique species of iguana for the islands of Saba and Monserrat. The painted black iguana, with its distinct black coloration, is an endemic species to these islands and must be recognized as such to help improve conservation efforts. Threats due to unsustainable harvesting (including pet trade) and habitat loss threaten the small remaining populations of these iguanas.

Genetic Analysis Finds Link in Coral Diseases

New research links two known coral diseases, skeletal eroding band and Caribbean ciliate infection, to a single originating pathogen. Studying the physical symptoms along with their genetic makeup, researchers were able to compare the disease-causing pathogens. Understanding these pathogens will prove instrumental in designing mitigation strategies to protect the remaining corals worldwide.

Sustainable Island Solutions through Science, Technology, Engineering and Mathematics (SISSTEM)

On August 1, 2019 the SISSTEM project kicked off at the University of Aruba, an ambitious program aimed at the development of critical capacity for Sustainable Island Solutions. SISSTEM advances sustainability policies at an academic level, supporting resilience in small island states while educating a new generation of academics that have the skills and capacity to make these policies a reality. SISSTEM offers a 3-year, 180 EC bachelor program in STEM with specializations in bio-environmental sciences, technology and engineering, and informatics and data sciences; a 1.5-year, 90 EC multidisciplinary master program, PhD projects for sustainable development in small island states and a research and development center. The SISSTEM project is the result of a collaboration between the University of Aruba, KU Leuven and the initial phase is funded by the EU as part of the EDF-11 fund.

New Butterfly Census for the Dutch Caribbean Windward Islands

The results of a four-year study were just published, cataloging the butterfly species of St. Eustatius over the winter months of 2009- 2012. This project also provided an update to species lists for the Dutch Caribbean islands of St. Eustatius, Saba and St. Maarten. The butterfly faunas of the three islands totals 44 species, including seven new species records for St. Eustatius. By comparing butterfly populations between different habitat types, the researchers determined which factors are important for increasing local diversity.

Survey of Free Roaming Livestock on St. Eustatius

The Caribbean Netherlands Science Institute (CNSI) recently conducted surveys of free-roaming livestock on St. Eustatius, highlighting population booms especially among goats and sheep. These animals can decimate local landscapes and be carriers of disease for native species and humans alike. Understanding population shifts is crucial in the sustainable management of the island’s natural resources.

Unlocking the Evolutionary Secrets of Local Amphibians and Lizards

Two new research projects were set out to map the evolution and historical geographical migration of key amphibian and reptile species within the Lesser Antilles. Understanding critical differences between similar species and how their particular evolutionary paths deviated from neighboring populations could prove crucial in the protection of these species moving forward. In January 2020 researchers from University of California and Smithsonian Institution visited St Maarten to collect data.
