Bycatch-reducing fish trap wins $20,000

2012-01-11T22:11:00Z

An innovative fish trap that allows small non-target fish to escape won a new content by RARE Conservation and National Geographic to fund solutions to overfishing. Developed through studies in Curaçao and Kenya with the Wildlife Conservation Society, the trap has gaps for juvenile fish to swim out of reportedly reducing bycatch by 80 percent. The entry won a $20,000 grant.

Photos: scientists find new species at world's deepest undersea vent

2012-01-10T16:06:00Z

It sounds like a medieval vision of hell: in pitch darkness, amid blazing heat, rise spewing volcanic vents. But there are no demons and devils down here, instead the deep sea vent, located in the very non-hellish Caribbean sea, is home to a new species of pale shrimp. At 3.1 miles below (5 kilometers) the sea's surface, the Beebe Vent Field south of the Cayman islands, is the deepest yet discovered.

Colombian president: no oil drilling in award-winning Seaflower marine reserve

2011-10-03T17:02:00Z

Colombian president, Juan Manuel Santos, announced over the weekend that there will be no oil exploration in the award-winning Seaflower Biosphere Reserve and Marine Protected Area (MPA). Spreading over 65,000 square kilometers (6,500,000 hectares), Seaflower MPA is home to over a hundred coral species, over 400 fish, some 150 birds, four marine turtles species, and the magnificent mollusk, the queen conch (Strombus gigas).

Featured video: the Caribbean's last mammals

2011-09-11T19:34:00Z

Although they are little-known, the hutia and solenodon are some of the last surviving mammals of the Caribbean. A hefty rodent, the hutia spends its time grazing in trees like a giant arboreal hamster. While, the solenodon may be one of the world's oddest creatures: a 'living fossil', the solenodon's evolutionary origins goes back all the way to the time of dinosaurs.

Reducing Disaster Risks: Progress and Challenges in the Caribbean Region

2011-08-23T23:32:00Z

Disaster management is a global policy problem with a critical land-use change component related to settlement patterns, deforestation, and agriculture development. This is further exacerbated by climate change.

Blue iguana back from the dead

2011-07-18T19:24:00Z

The blue iguana (Cyclura lewisi) was once king of the Caribbean Island, Grand Cayman. Weighting in at 25 pounds, measuring over 5 feet, and living for over sixty years, nothing could touch this regal lizard. But then the unthinkable happened: cars, cats, and dogs, along with habitat destruction, dethroned Grand Cayman's reptilian overlord. The lizard went from an abundant population that roamed the island freely to practically assured extinction. In 2002, researchers estimated that two dozen—at best—survived in the wild. Despite the bleak number, conservationists started a last ditch effort to save the species. With help from local and international NGOs, the effort, dubbed the Blue Iguana Recovery Program, has achieved a rarity in conservation. Within nine years it has raised the population of blue iguanas by twenty times: today 500 wild blue iguanas roam Salina Reserve.

Photos: new bat uncovered in the Caribbean

2011-05-26T16:37:00Z

Researchers have declared a new species of bat from the Caribbean island of St. Vincent. While the new bat had been documented before, it was long believed to be a member of a similar species that is found throughout South America and a few Caribbean Islands, that is until PhD student Peter Larsen noticed it was far larger than its relative down south.

Richard Branson's pet lemur project is a terrible idea

2011-04-19T20:56:00Z

Richard Branson's plan to introduce lemurs on one of his private islands in the Caribbean is a terrible idea if he really aims to protect the primates from extinction. Beyond the much-discussed ecological impact of bringing in non-native primates, Branson's scheme risks undermining conservation efforts where lemurs actually exist in the wild: Madagascar.

Haiti's deforestation has dire economic impacts

2011-02-09T18:05:00Z

December Climate talks in Cancun highlighted the importance of maintaining healthy forests to protect the planet’s most vulnerable people from the consequences of future climate change. Haitians have been glimpsing that future for more than a year after a lack of healthy forests left them vulnerable to other disasters. Here’s a look at the take-home lessons from Haiti’s year of environmental ruin.

Pictures: 6 'lost' frog species discovered in Haiti

A new atlas produced by the United Nations Environment Programme (UNEP) combines striking satellite images and rigorous data to present a unique and complex view of environmental changes taking place in Latin America and the Caribbean.

Beyond gloom: solutions to the global coral reef decline

2010-11-10T21:45:00Z

The world's coral reefs are in trouble. Due to a variety of factors—including ocean acidification, warming temperatures from climate change, overfishing, and pollution—coral cover has decline by approximately 125,000 square kilometers in the past 50 or so years. This has caused some marine biologists, like Charlie Veron, Former Chief Scientist of the Australian Institute of Marine Science, to predict that coral reefs will be largely extinguished within a century. This year alone, large-scale coral bleaching events, whereby coral lose their symbiotic protozoa and become prone to disease and mortality, were seen off the coasts of Indonesia, the Philippines, and some Caribbean islands. However a new paper in Trends in Ecology and Evolution attempts to dispel the gloom over coral reefs by pointing to strategies, and even some successes, to save them.

World's rarest snake making a comeback

2010-11-02T17:54:00Z

The Antiguan racer (Alsophis antiguae) shares a similar story with many highly endangered island species. Invasive mongoose killed every racer on the Caribbean island of Antigua, leaving only a small population on nearby Great Bird Island. Confined to 8 hectares, this final population was being killed-off by invasive Eurasian black rats. By the time conservationists took action, only 50 Antiguan racers survived in the world. But here's where the story turns out different: 15 years later, a partnership between six conservation groups has succeeded in raising the population tenfold to 500 snakes and expanded its territory to other islands through snake-reintroductions.

Colombian marine reserve receives top honors at global biodiversity meeting

2010-10-20T22:07:00Z

Coralina, a Colombian government agency that established the Seaflower Marine Protected Area (MPA) with local community involvement, is being heralded today by the Convention on Biological Diversity (CBD) in Nagoya, Japan. Proving that conservation and sustainable economic opportunities can go hand-in-hand, Coralina was instrumental in creating a marine park that protects nearly 200 endangered species while providing sustainable jobs for local people in the Western Caribbean Colombian department of Archipelago of San Andrés, Old Providence and Santa Catalina. Coralina was one of over 1,000 agencies and organizations that are apart of the Countdown 2010 program, which highlights effective action to save species at the CBD.

The Oily History of Offshore Operations: From Venezuela to the Gulf

2010-05-01T19:06:00Z

Though undoubtedly shocking and disconcerting, the recent BP oil spill in the Gulf of Mexico is hardly the first incident of its kind in the region. Indeed, as I watched the footage of the ominous oil spill approaching the ecologically sensitive coast of Louisiana, I was struck with a profound sense of déjà vu. Long ago, while researching my dissertation on the environmental history of the petroleum industry in Venezuela, I combed through archives and libraries in the U.S., Britain and South America to uncover the oil companies’ sordid past. Starting in the 1920s, American and British subsidiaries of Standard Oil of New Jersey, Gulf and Royal Dutch Shell turned environmentally pristine Lake Maracaibo, which empties out into the Gulf of Venezuela and the Caribbean, into toxic sludge

Octopus pretends to be flounder to avoid predators

2010-03-04T17:29:00Z

Marine researchers have discovered the Atlantic longarm octopus mimicking not only the color and appearance of the peacock flounder, but also its unique style of swimming in order to convince predators it's something it's not.

The Caribbean's wonderfully weird (and threatened) mammals, an interview with Jose Nunez-Mino

2010-01-18T21:30:00Z

Not many people know the solenodon and the hutia, yet for the fortunate few that have encountered them, these strange little-studied mammals—just barely holding on in the Caribbean island of Hispaniola—deserve to be stars of the animal kingdom. "I could not quite believe it the first time I held a solenodon; I was in utter awe of this mesmerizing mammal. […] They have a long flexible snout which is all down to the fact that it is joined to the skull by a unique ball-and-socket joint. This makes it look as if the snout is almost independent to the rest of the animal. You can’t help but feel fascinated by the snout and inevitably it does make you smile," Dr. Jose Nunez-Mino, the Project Manager for a new initiative to study and conserve the island's last mammals, told mongabay.com in an interview.

If protected coral reefs can recover from global warming damage

2010-01-10T17:14:00Z

A study in the Caribbean has found that coral reefs can recover from global warming impacts, such as coral bleaching, if protected from fishing. Marine biologists have long been worried that coral reefs affected by climate change may be beyond recovery, however the new study published in PLoS ONE shows that alleviating another threat, overfishing, may allow coral reefs to cope with climate change.

Nations vulnerable to global warming present demands: carbon levels below 350ppm and billions in aid

2009-11-10T18:59:00Z

A group of nations especially vulnerable to the effects of climate change have released a declaration calling for developed countries to keep CO2 emission below 350 parts per million (ppm) and to give 1.5 percent of their gross domestic product to aid developing nations in adapting to the myriad impacts of climate change.

Cement mining puts Dominican Republic park at risk

New species of glowing mushrooms named after Mozart's Requiem

2009-10-14T03:09:00Z

Classical musical genius, Wolfgang Amadeus Mozart, probably never expected his music to inspire mycologists, but fungi researchers have announced in the journal Mycologia that two new species of glowing mushroom are named after movements in the composer's Requiem: Mycena luxaeterna (eternal light) and Mycena luxperpetua (perpetual light).

Fish take less than a decade to evolve

2009-06-22T05:55:00Z

Evolution is often thought of being a slow-process, taking thousands, if not millions, of years. However a new study in The American Naturalist found that Trinidadian guppies underwent evolution in just eight years, or thirty generations. Less than a decade ago Swanne Gordon, a graduate student at UC Riverside, and her team introduced Trinidadian guppies into the Damier River in the Caribbean island of Trinidad. They placed the guppies above a waterfall to allow them to flourish in a largely predator-free environment.

Tropical storms may create seeds for reef restoration

2009-05-16T21:37:00Z

Tropical reefs are easy to destroy and difficult to fix. It is estimated that global warming, unsustainable fishing, and pollution have already destroyed 20% of the world’s coral reefs. Recently, Virginia Garrison and Greg Ward of the United States Geological Survey (USGS) demonstrated how coral fragments that have broken loose during storms can be used to rebuild reefs. They reported their results in the October issue of Biological Conservation.

Secret movements of the basking shark uncovered

2009-05-07T18:50:00Z

Researchers with the Massachusetts Mariner Fisheries have uncovered the secret life of the world’s second largest fish, known for its cavernous mouth. The basking shark, which measures over 10 meters and weighs as much as seven tons, has long baffled scientists by disappearing from view half of every year. A new study from Current Biology found that the basking shark spends this time deep in the Atlantic’s tropical waters.

Coral reef loss in Caribbean leads to ongoing fish declines

2009-04-30T16:46:00Z

Analyzing 48 surveys of Caribbean fish populations over fifty years, from 1955-2007, a new meta-study has found that fish populations in the famously clear waters began to drop in the mid-90s, leading to a consistent decline that hasn’t stopped. The study published in Current Biology discovered a region-wide decline of about 3-6 percent per year in three out of six trophic groups of fish, i.e. groupings of species categorized by their place on the food chain. The declines didn’t show major differences between species targeted by fishermen and those that are not, implying that overfishing isn’t the only cause of the decline in the Caribbean.

After disease engulfs island, rare mountain chicken frogs airlifted to safety

2009-04-23T16:13:00Z

In a rescue operation that sounds straight out of an action film, 50 mountain chicken frogs were airlifted from the Caribbean island Montserrat after the discovery of Chytridomycosis, a fungal disease that has wiped out amphibian populations worldwide. Already, hundreds of the critically-endangered mountain chicken frogs succumbed to the disease, which is thought to have made its way to the island in late 2008 or early 2009.

Climate change could devastate lizards in the tropics

2009-03-04T00:13:00Z

With help from data collected thirty years ago, scientists have discovered that tropical lizards may be particularly sensitive to a warming world. Researchers found that lizards in the tropics are more sensitive to higher temperatures than their relatives in cooler, yet more variable climates. "The least heat-tolerant lizards in the world are found at the lowest latitudes, in the tropical forests. I find that amazing," said Raymond Huey, lead author of a paper appearing in the March 4 Proceedings of the Royal Society B.

Fishermen - not whales as claimed by Japan - are the cause of fisheries depletion

2009-02-12T18:59:00Z

Fishermen calling for a resumption of whaling to restore commercial fish stocks are taking the wrong approach, argue researchers writing in the journal Science. Analyzing data on fish catch and whale abundance off the coast of northwestern Africa and the Caribbean, Leah R. Gerber and colleagues show that fishermen remove far more fish than whales consume, undermining the agreement by whaling nations that whales are driving depletion of fisheries.

Rediscovery of the solenodon, a rare venomous mammal, in Haiti

2009-01-09T04:45:00Z

In the journal Oryx researchers from EDGE, a program of the Zoological Society of London (ZSL), have announced the rediscovery of a small population of Hispaniolan solenodons in Haiti. At the same time scientists in the Dominican Republic have taken the first ever footage of this endangered mammal.

Scientists discover world's smallest snake species

2008-08-03T14:30:39Z

If one wanted to overcome their fear of snakes, they may want to start with the newly discovered Leptotyphlops carlae. Measuring less than four inches long, even stretched out this new species of threadsnake can't compete with the average pen or pencil.

Fast-growing coral may help reefs survive global warming

2008-03-13T14:30:39Z

Two fast-growing coral species may hold the key to Caribbean reefs surviving global warming, report researchers writing in the journal Science.

Human activity is killing coral reefs in the Caribbean

2008-01-08T14:30:39Z

A wide and thorough study of the Caribbean's coral reefs--including 322 sites in 13 countries--has shown that the main indicator of coral destruction in the Caribbean is the proximity of human populations: the larger the population the greater the deterioration of the reefs. Contributing factors are numerous, but the study showed that coastal development causes the most damage to coral reefs and fish populations, because of increased sewage and fishing pressure; while proximity to agriculture results in macroalgae due to runoff of agricultural chemicals.

Dean was 3rd most intense Atlantic hurricane at landfall

Cuba Energy Crisis Solved

2007-07-05T14:30:39Z

Cuba may be overcoming its intermittent energy crisis, according to a top U.N. official. Power shortages and brownouts have long been a problem in the small communist island nation, but it was daily 16 hour-electricity cuts in 2004 that finally forced the government to act. Its efforts are apparently paying off.

Frogs rafted from South America to the Caribbean 29M years ago

2007-06-04T14:30:39Z

Large populations of frogs in Central America and the Caribbean rafted, over the ocean from South America more than 29 million years ago, reports a new study published in the June 4 early online edition of The Proceedings of the National Academy of Sciences.

Coral species may help fight global warming impact

2007-03-04T14:30:39Z

While many coral species appear to be potentially doomed by global warming, some species may help fight the impact of climate change, in effect helping protect coral reef ecosystems, argues a Cornell University biologist.

Europeans may have caused extinction of large mammals in Caribbean

2007-01-25T14:30:39Z

New evidence suggests that the arrival of Europeans in the New World corresponds with the extinction of mammal species on the Caribbean islands.

Historic Caribbean sea turtle population falls 99%

2006-08-01T15:19:39Z

Current conservation assessments of endangered Caribbean sea turtles are too optimistic due declines of populations on historically important nesting beaches, according to new research from the Scripps Institution of Oceanography. The plunge has significant ecological consequences.

Severe damage expected for Caribbean coral reefs in 2006

2006-07-04T15:19:39Z

Caribbean Sea temperatures have reached their annual high two months ahead of schedule according to a report from The Associated Press. Scientists are concerned that the region's coral reefs may suffer even worse damage than last year when 70 percent of coral was bleached in some areas.

Dominican Delights - Dominica, the real Caribbean

2006-05-04T15:19:39Z

Prepare yourself. Here, there are no white sand beaches, no golf courses. Here, you'll find a boiling lake, winding cliff-side roads, bubbling surf and waterfalls that will make your head spin. This is Dominica, and this is the real Caribbean. Our Easter holiday to this (officially) English-speaking leeward island sandwiched between French neighbors Guadeloupe to the north and Martinique to the south gave us six days to explore enchanting coves, impressive mountains and dozens of rivers. In six short days, we were overwhelmed by Dominica's charms -- her incredible natural beauty and local creole style. Travelers looking to explore and discover, to be educated and reinvented, should consider this an ideal place for a serious Caribbean adventure.

Global warming could dry Caribbean, Central America

2006-04-14T15:19:39Z

Parts of the Caribbean and Central America are likely to experience drier summers by 2050 according to research presented by UCLA atmospheric scientists in the April 18 issue of Proceedings of the National Academy of Sciences (PNAS). Analyzing 10 global climate computer simulations from various agencies, the researchers found that the majority of the computer models predict a substantial decrease in tropical rainfall to occur by mid-century. By the end of this century, the models show that summer rainfall could decline by 20 percent or more in parts of the Caribbean and Central America.

Damaged Caribbean reefs under attack
