New Carmabi report on the current state of Curacao’s coral reefs 2012

To download the report, Vermeij MJA (2012) Curacao State of the reef 2012 Carmabi (c)2012 Papiamentu follows english below The coral reefs of Curaçao represent one of the best reef systems left in the Caribbean at present. However, this does not mean that these reef systems are doing well.  On the contrary: increased coastal development has resulted in pollution of near shore waters through the release of (untreated) sewage, nutrients and chemicals and overfishing represent some of the factors that have [...]

Strange symptoms in reef fish

Recently a large number of fish species has been observed carrying signs of what could be a disease. Two types have been observed and herbivorous fish seem most affected. The first "disease" was historically observed on surgeonfish (A. bahianus), but is now also occuring on several species of grunts and hamlets. Indiviuals affected are covered by dark, round patches, usually dark grey/ black in color, that can occur all over their body. Examples of this "disease" are shown  in [...]

New study on the state of Bonaire’s reefs

Although Bonaire’s coral reefs remain among the healthiest and most resilient in the Caribbean, a new  IUCN report based on the IUCN Resilience Assessment of Coral Reefs highlights some of the threats that exist to Bonaire’s coral reefs, and which could have serious implications for resilience to future climate change and other threats. The report identified recommendations for addressing the current threats, as well as high and low resilience sites. Carmabi helped with the study which can be found [...]

UPDATED: Caribbean coral species identification tool

There have also been some updates on the coral ID pages. Carmabi compiled a series of pictures that show combinations of corals that are often mistaken  for one another. Because terminology to describe each species is often  subjective (i.e. has larger polyps or smaller ridges) having both  species in one picture might help to get a better idea of how such  closely related/ similar looking "species" can be distinguished from one  another. Corals are now divided in four main [...]

High seawater temperatures cause worst coral bleaching since 1998

Temperatures continue to look bad for the Caribbean in 2010. At this point, our Degree Heating Week product is as bad as, or worse than, this time in 2005. Our Seasonal Bleaching  Outlook indicates there continues to be a risk of thermal stress in 2010 at levels similar to 2005. The good news is that areas north of the Greater Antilles and in the Gulf of Mexico do  not seem to be at as high a risk. Temperatures in [...]

Unidentifiable fish species

On the evening of May 30th a fish was caught by local fishermen at a depth of approximately 100 meters. At present no one has any idea what species this fish might be. A picture is shown below and all who know what species this fish is are invited to send an email to m.vermeij@carmabi.org with the supposed species name so the information can be shared with the local fishing community. Thanks in advance. Update June 3rd 2010: After sending the [...]

Baby corals dance their way home

Baby corals find their way home in their first days as free-swimming larvae by listening to the noise of animals on the reef and actively swimming towards it, an international team of researchers working in the Caribbean has discovered. These findings raise new concerns for the future of coral reefs as increasing human noise pollution in the world's oceans is masking reef sounds. Dr Steve Simpson, Senior Researcher in the University of Bristol's School of Biological Sciences, discovered several years ago [...]

Research at Carmabi highlighted in NATURE

Work on sponges on Curacaoan reefs by Jasper de Goeij, a Carmabi associate scientist, has been highlighted in NATURE, one of world's leading scientific journals. Below one finds the text of the article: How the sponge stays slim: One species' rapid cell shedding explains its huge carbon-catching capacity. Published online Nature doi:10.1038/news.2009.1088 By: Matt Kaplan Biologists have discovered how a reef-dwelling species of sponge can filter enormous amounts of carbon without growing in size.The sponge Halisarca caerulea can absorb up to two-thirds of [...]

New report on impacts of climate change on Caribbean nations and natural resources

A new report spearheaded by the CARIBSAVE project under UNDP funding highlights the impacts of climate change on Caribbean nations and natural resources. In particular, the report highlights the difference in the impacts at the 2.0°C increase being pushed by many UN negotiators vs. the 1.5°C increase promoted by the Alliance of Small Island States. The report focuses on: the implications of ice sheet melt for global sea level rise (SLR); the projections and implications of SLR for the [...]
