Eleven Species of Mosquitoes found on Leeward Dutch Caribbean Islands

A 2018 study of mosquito populations on the islands of Sint Maarten, Saba and Sint Eustatius documented eleven different species, including two new species for Sint Maarten, a number of which are known to spread mosquito-borne diseases. Understanding mosquito populations can help local governments prepare themselves against the spread of mosquito-borne diseases as well as provide insight to the health of local ecosystems.

Coral Spawning Predictions for the South Caribbean

Caribbean Research and Management of Biodiversity (CARMABI) has released its annual coral spawning prediction calendar for the south Caribbean. This calendar plays a central role in studying the reproductive biology of Caribbean corals and guiding coral restoration efforts for the southern Dutch Caribbean islands. Based off these predictions, researchers are able to harvest coral gametes that are reared to larvae that can be used to cultivate future coral colonies.

Leeward Blindsnake: Native to St. Eustatius

Using DNA-and morphological analysis, a team from Reptile, Amphibian and Fish Conservation Netherlands (RAVON) and Naturalis have discovered that the Leeward Blindsnake is a native species to the island of St. Eustatius. Understanding the island’s native reptile population will help design and implement conservation measures to protect this near threatened species in the future.

Using Lemon Trees to Combat Coralita on Saba

Between December 2017 and June 2018, members of the St. John’s community planted five lemon trees to bring attention to and work towards the eradication of the invasive Coralita vine on Saba. Using updated Participatory Action Research techniques, researchers were able to inspire community involvement which had previously been hindered due to a lack of interest and understanding.

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.
