(04/15/2013) Fishing is not a woman's domain in most countries across the globe. In parts of India there are fishing communities who believe that having a woman onboard a fishing boat brings bad luck. Despite this, Divya Karnad, a scientist who studies marine life in India, has spent several years studying fisheries and their impact on species like sharks and sea turtles. Her work forms a part of global efforts to track declining marine species and encourage more sustainable fishing.
Scientists discover new genus of crustacean
(03/27/2013) In recent journeys to Madagascar, New Caledonia, Vanuatu, the Philippines, and French Polynesia, scientists from the Centre for Advanced Studies of Blanes and the University of Barcelona have discovered not only five new crustaceous species, but also the existence of a new genus in the family.
Typhoon Bopha decimated coral reefs
(01/24/2013) When Typhoon Bopha, also known as Pablo, ran ashore on Mindanao, it was the largest tropical storm it ever hit the Philippine island. In its wake the massive superstorm left over 1,000 people were dead and 6.2 million affected with officials saying illegal logging and mining worsened the scale of the disaster. However, the Category 5 typhoon also left a trail of destruction that has been less reported: coral reefs.
Threatened Galapagos coral may predict the future of reefs worldwide
(11/07/2012) The Galapagos Islands have been famous for a century and a half, but even Charles Darwin thought the archipelago’s list of living wonders didn’t include coral reefs. It took until the 1970s before scientists realized the islands did in fact have coral, but in 1983, the year the first major report on Galapagos reef formation was published, they were almost obliterated by El Niño. This summer, a major coral survey found that some of the islands’ coral communities are showing promising signs of recovery. Their struggle to survive may tell us what is in store for the rest of the world, where almost three-quarters of corals are predicted to suffer long-term damage by 2030.
Above the ocean: saving the world's most threatened birds
(11/01/2012) A life on the ocean is a perilous one for any bird. They must expend energy staying aloft for thousands of miles and learn to be marathon swimmers; they must seek food beneath treacherous waves and brave the world's most extreme climates; they must navigate the perils both of an unforgiving sea and far-flung islands. Yet seabirds, which includes 346 global species that depend on marine ecosystems, have evolved numerous strategies and complex life histories to deal with the challenges of the sea successfully, and they have been doing so since the dinosaur’s last stand. Today, despite such a track record, no other bird family is more threatened; yet it's not the wild, unpredictable sea that endangers them, but pervasive human impacts.
Great Barrier Reef loses half its coral in less than 30 years
(10/01/2012) The Great Barrier Reef has lost half of its coral cover in the last 27 years, according to a new study released today in the Proceedings of the National Academy of Sciences (PNAS). Based on over 2,000 surveys from 1985 to this year the study links the alarming loss to three impacts: tropical cyclone damage, outbreaks crown-of-thorns starfish that devour corals, and coral bleaching.
Coral diversity off Madagascar among the world's highest
(09/24/2012) The western Indian Ocean, especially the waters between Madagascar and mainland Africa, may be among the world's most biodiverse for coral species, according to a new study in PLOS ONE. Conducting dive surveys in the region for nearly a decade, David Obura with the Coastal Oceans Research and Development in the Indian Ocean (CORDIO) identified 369 coral species in the western Indian Ocean and predicts there may be nearly another 100 unidentified. If so, this would make the region as biodiverse as the Great Barrier Reef, but still behind the Coral Triangle which has over 600 species.
'Monster larva' turns into a shrimp
(08/28/2012) With blue devil-shaped horns and red armor, the monster larva, or Cerataspis monstrosa, kept scientists guessing for nearly 200 years; infrequently found in the bellies of marine predators, researchers could not imagine what this larva became as an adult. Now they do: the monster larva becomes a deep sea shrimp, known as Plesiopenaeus armatus, which bares little monstrous resemblance to its larval stage, according to DNA studies published in Ecology and Evolution.
'Time pollution': loss of predators pushes nocturnal fish to take advantage of the day
(06/25/2012) Nocturnal fish—which sport big eyes for improved night vision—are taking back the day in the coral reefs of the Tabuaeran Atoll, according to a new study in the open-access journal PLoS ONE. Overfishing has plundered the Pacific atoll of many of its notable predators, including sharks and barracudas, causing ripple effects through the ecosystem. One of these emerging changes appears to be that with less fear of being eaten, nocturnal fish are increasingly venturing out during the day.
World failing to meet promises on the oceans
(06/14/2012) Despite a slew of past pledges and agreements, the world's governments have made little to no progress on improving management and conservation in the oceans, according to a new paper in Science. The paper is released just as the world leaders are descending on Rio de Janeiro for Rio+20, or the UN Summit on Sustainable Development, where one of the most watched issues is expected to be ocean policy, in part because the summit is expected to make little headway on other global environmental issues such as climate change and deforestation. But the new Science paper warns that past pledges on marine conservation have moved too slowly or stagnated entirely.
Scientists recommend marine protected areas for Madagascar
(02/27/2012) With the government of Madagascar planning to increase marine protected areas by one million hectares, a group of researchers have laid out flexible recommendations in a new study in the open access journal PLoS ONE. The researchers employed four different analyses in order to highlight a number of different conservation options, however the different analyses pointed to the need to protect certain areas with high biodiversity, including the Barren Islands' reefs, the reefs of Juan de Nova, the Banc de Leven, and the shallow banks of the Cap Sainte Marie.
