President's pledge to ban commercial fishing around Pacific island nation slow to materialize
(09/23/2013) In 2010 President Anote Tong of Kiribati made a historic pledge, committing to protect the waters around his island nation in a massive marine protected area. He said the gesture represented Kiribati’s contribution to protecting the environment and he urged industrial countries to do the same by cutting their greenhouse gas emissions, which threaten low-lying islands with rising sea levels. The commitment raised Tong’s profile, winning him international accolades, and boosted the tiny country’s standing in the fight against climate change. But since 2010 questions have begun to emerge about the extent of Tong’s commitment.
Mesoamerican Reef needs more local support, says report
(09/13/2013) From massive hotel development through the agriculture industry, humans are destroying the second largest barrier reef in the world: the Mesoamerican Reef. Although global climate change and its effects on reefs via warming and acidification of coastal waters have made recent headlines, local human activities may destroy certain ecosystems before climate change has a chance to do it. The harmful effects of mining, agriculture, commercial development, and fishing in coastal regions have already damaged more than two-thirds of reefs across the Caribbean, in addition to worsening the negative effects of climate change.
Google Earth presents fish-eye view of coral reefs
(08/20/2013) You can now visit up-close and personal some of the world's most imperiled ecosystems on Google Earth: coral reefs. The Google team is working with scientists to provide 360 degree panoramas, similar to Google street-view, to give armchair ecologists a chance to experience the most biodiverse ecosystems under the waves.
Journey to the Edge of Eden: the struggle to preserve Southwest Florida
(08/05/2013) Gary Schmelz, in a Journey to the Edge of Eden, takes us through a wonderful personal account of the conservation history of Southwest Florida. Journey to the Edge of Eden is one part personal memoir similar to the English naturalist Gerald Durrell and one part Florida conservation history. With hilarious stories of unintended naturalist misadventures and recounting conservation “as it happened,” a Journey to the Edge of Eden is one of those rare books you read in a coffee shop and with gusto and pride while laughing along out loud at Gary Schmelz stories.
Plan to preserve the world's 'last ocean' killed by Russia
(07/16/2013) As the most pristine marine ecosystem on the planet, Antarctica's Ross Sea has become dubbed the world's "last ocean." Home to an abundance of penguins, whales, orcas, seals, and massive fish, the Ross Sea has so far largely avoided the degradation that has impacted much of the world's other marine waters. However, a landmark proposal to protect the Ross Sea, as well as the coastline of East Antarctica, has failed today due to opposition by Russia.
San Francisco seafood restaurants go sustainable
(07/02/2013) The Seafood Watch Program, first created by Monterey Bay Aquarium in the late 1990s, is arguably the best-known guide to sustainably-caught seafood in the U.S. Listing seafood choices in three categories—green (best choices), yellow (good alternatives), and red (avoid)—the guide informs consumers of the best options. However, it's one thing to create a well-respected guide, and another issues altogether to get producers and consumers to use it. But a newer partnership, the San Francisco Seafood Watch Alliance, is working to bridge this gap. Maggie Ostdahl of Aquarium of the Bay works with the Seafood Watch Restaurant program and restaurants across San Francisco—one of the best places in the country for seafood—to source sustainable seafood. Restaurant partners avoid seafood on the guide's red list.
UN may downgrade Great Barrier Reef's heritage status due to Australia's inaction on threats
(06/17/2013) The federal government insists it is striving to avoid the Great Barrier Reef being listed 'in danger' ahead of a crunch UN meeting, after rejecting a Senate recommendation to block new port developments near the World Heritage ecosystem.
Ocean acidification pushing young oysters into 'death race'
(06/11/2013) Scientists have long known that ocean acidification is leading to a decline in Pacific oyster (Crassostrea gigas) in the U.S.'s Pacific Northwest region, but a new study in the American Geophysical Union shows exactly how the change is undercutting populations of these economically-important molluscs. Caused by carbon dioxide emissions, ocean acidification changes the very chemistry of marine waters by lowering pH levels; this has a number consequences including decreasing the availability of calcium carbonate, which oysters and other molluscs use to build shells.
Costa Rican environmentalist pays ultimate price for his dedication to sea turtles
(06/10/2013) On the evening of May 30th, 26-year-old Jairo Mora Sandoval was murdered on Moin beach near Limón, Costa Rica, the very stretch of sand where he courageously monitored sea turtle nests for years even as risks from poachers rose, including threats at gunpoint. A dedicated conservationist, Sandoval was kidnapped along with four women volunteers (three Americans and one from Spain) while driving along the beach looking for nesting sea turtles. Sandoval was separated from the women—who eventually escaped their captors—but the young Costa Rican was stripped naked, bound, and viciously beaten. Police found him the next day, face-down and handcuffed in the sand; Sandoval died of asphyxiation.
Manta ray tourism worth 28 times more than killing them for Traditional Chinese Medicine
(06/03/2013) A new study in the open access journal PLoS ONE estimates that manta rays are worth $140 million a year in tourism across 23 countries, significantly outweighing the worth of manta ray gill plates, which have become the newest craze in Traditional Chinese Medicine.
Biosphere conservation: monumental action is critical to avert global environmental crisis
(05/20/2013) Human-caused changes to our biosphere—the global total of the world's ecosystems—are now so great and alarmingly rapid that human lives and societies undoubtedly face epic challenges in the near future as our biosphere deteriorates, planetary boundaries are reached, and tipping points exceeded. We may survive, we may painfully adapt, but it is a fair bet that grave hardship, loss, and sacrifice lay ahead. The nature and extent of impacts among human populations hinges on how successfully we respond to the biosphere crisis with extraordinary leadership, balanced solutions applied at global scales, and unprecedented cooperation—or not.
Industrialized fishing has forced seabirds to change what they eat
(05/14/2013) The bleached bones of seabirds are telling us a new story about the far-reaching impacts of industrial fisheries on today's oceans. Looking at the isotopes of 250 bones from Hawaiian petrels (Pterodroma sandwichensis), scientists have been able to reconstruct the birds' diets over the last 3,000 years. They found an unmistakable shift from big prey to small prey around 100 years ago, just when large, modern fisheries started scooping up fish at never before seen rates. The dietary shift shows that modern fisheries upended predator and prey relationships even in the ocean ocean and have possibly played a role in the decline of some seabirds.
New endangered list for ecosystems modeled after 'Red list' for species
(05/09/2013) The IUCN has unveiled the first iteration of its new Red List of Ecosystems, a ranking of habitats worldwide.
Scientists discover that marine animals disperse seagrass
(05/09/2013) Lesser known than coral reefs, marine seagrass ecosystems are rich in biodiversity and are powerhouses when it comes to sequestering carbon dioxide. Yet, much remains unknown about the ecology of seagrass beds, including detailed information on how seagrass spread their seeds and colonize new area. Now a recent study in Marine Ecology Progress Series documents that several species of marine animal are key to dispersing seagrass, overturning the assumption that seagrass was largely dispersed by abiotic methods (such as wind and waves).
Featured video: saving sea turtles in Mexico's Magdalena Bay
(05/09/2013) A new short film, Viva la tortuga documents the struggle to save loggerhead and green sea turtles in Magdalena Bay, Mexico. Once a region for a massive sea turtle meat market, the turtles now face a new threat: bycatch. Loggerhead sea turtles are drowning in bottom-set gillnets, unable to escape from the nets once entangled. The issue has even raises threats of trade embargoes from the U.S.
Are seagulls killing whales in Patagonia?
(05/08/2013) It sounds ludicrous, but it could just be true: scientists say seagulls may be responsible for hundreds of southern right whale moralities off the Argentine coastline. Since 2003, scientists have documented the deaths of 605 southern right whales (Eubalaena australis) near Península Valdés which the whales use as a nursery. Notably, 88 percent of these were newborn calves. The death rate is so high that researchers now fear for the whales' long-term survival.
Munching on marine plastic kills sperm whale
(05/07/2013) What do children's toys, balloons, mattresses and plastic bags have in common? They can, along with more non-biodegradable pollutants, be found in the belly of a sperm whale, the topic of a new study in the Marine Pollution Bulletin. The same whale that swallowed Jonah from the Bible, Geppetto from Collodi's Pinocchio, and the crew of the Pequod from Melville's Moby-Dick is now swallowing trash from the Spanish-Mediterranean coast, and in the Strait of Gibraltar.
Breaking the mold: Divya Karnad takes on fisheries and science journalism in India
(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.
Proposed coal plant threatens Critically Endangered Philippine cockatoo
(04/02/2013) One kilometer off the Philippine island of Palawan lies the Rasa Island Wildlife Sanctuary; here forest grows unimpeded from a coral island surrounded by mangroves and coral reefs. Although tiny, over a hundred bird species have been recorded on the island along with a major population of large flying foxes, while in the waters below swim at least 130 species of coral fish, three types of marine turtles, and that curious-looking marine mammal, dugongs. Most importantly, perhaps, the island is home to the world's largest population of Philippine cockatoos (Cacatua haematuropygia), currently listed as Critically Endangered. But, although uninhabited by people, Rasa Island may soon be altered irrevocably by human impacts.
Sharks and rays win protections at CITES
(03/11/2013) Today, for the first time, sharks and rays have won the vote for better protection under CITES (the Convention on International Trade in Endangered Species), the world's regulating body on trade in threatened species. Five shark species and manta rays, which includes two species, have received enough votes to be listed under Appendix II of CITES, which means tougher regulations, but not an outright ban. However, the votes could still be overturned before the end of the meeting.
Has shark fin consumption peaked at 100M dead sharks per year?
(03/05/2013) While a new study warns that up to 100M sharks are killed annually, there are signs out of China that demand for shark fin may be on the decline. A study published last week in the journal Marine Policy estimated shark deaths at 100 million in 2000 and 97 million in 2010, suggesting a slight drop in shark killing. Meanwhile reports out of China in recent months suggest an accelerating decline in shark fin consumption. China is the top market for shark fin, which is consumed as a status symbol, typically at wedding ceremonies and business dinners.
Leatherback sea turtles suffer 78 percent decline at critical nesting sites in Pacific
(02/27/2013) The world's largest sea turtle, the leatherback (Dermochelys coriacea), is vanishing from its most important nesting sites in the western Pacific, according to a new study in Ecosphere. Scientists found that leatherback turtle nests have dropped by 78 percent in less than 30 years in the Bird's Head Peninsula on the island of New Guinea. Worryingly, these beaches account for three-fourths of the western Pacific's distinct leatherback population; globally the leatherback is listed as Critically Endangered by the IUCN Red List, the highest rating before extinction.
From the brink of extinction: elephant seals stage remarkable comeback
(01/23/2013) In the 19th century the Northern Pacific Elephant was thought to be extinct until a small population was discovered on an island of Baja California in 1892. Since then, the species has staged a remarkable comeback which was greatly accelerated by protective measures adopted by the U.S. and Mexican governments. The recovery is especially evident on the beaches of California's Año Nuevo State Park. Until the 1950s so individuals were observed in the park. In the 1960s pups started to be born on Año Nuevo's sandy shores. By the 1990s thousands of pups where born each year, capping the elephant seal's turnaround. 'Beachmaster', a new film by Christopher Gervais and Stan Minasian, tells the conservation success story of their recovery.
Telling the story of the father of sea turtle conservation
(01/21/2013) In 1959, visionary Archer Carr founded the world's first conservation group devoted solely to sea turtles. Working with these marine denizens in Costa Rica, Carr was not only instrumental in changing local views of the turtles—which at the time were being hunted and eaten at unsustainable rates—but also in establishing basic practices for sea turtle conservation today. Now a new film by Two-Head Video, Inc. tells the story of Carr's work and the perils still facing marine turtles today.
Saving manta rays from the fin trade
(01/15/2013) Tens of millions of sharks and rays are killed each year to meet demand for shark fin, a delicacy across East Asia. But while the plight of sharks has gained prominence in international environmental circles in recent years, the decline in rays has received considerably less attention. A new film, Manta Ray of Hope, aims to change that. Produced by cinematographer, scuba diver, and marine conservationist Shawn Heinrichs, Manta Ray of Hope offers a look at the mysterious and magnificent world of the world's largest ray, the manta ray. The film highlights both the threats mantas face as well as some of the people who are working to save them.
Obama triples area of protected California coastline
(12/20/2012) Today President Obama announced the government would add almost 3,000 square miles of California coastline to the National Marine Sanctuary system, roughly tripling its size, reports the Sierra Club.
Measuring nutrient pollution in pristine waters: Puerto Rico's Vieques Island
(12/10/2012) Life in the ocean require nutrient, but too much of a good thing can be hugely detrimental. Nutrient pollution from agricultural and industrial runoff causes serious ecological harm in the world's marine waters, at times producing massive "dead zones" where much of the dissolved oxygen has been stripped making it difficult for most marine animals to live there. A new study by scientists with the U.S. National Oceanic and Atmospheric Administration (NOAA) attempts to establish a baseline of nutrient levels in the largely pristine waters around the island of Vieques off of Puerto Rico.
Jeff Corwin talks sharks
(12/04/2012) Sharks are among the most feared of all the world's predators, yet humans kill tens of millions of sharks for every person who falls victim to shark attack. Part of our fear stems from lack of understanding. A new eBook however tries to change that. Jeff Corwin, an Emmy Award Winning TV host, has this week released Jeff's Explorer Series: SHARKS, the first of a new eBook series, which Corwin likens to the 21st century version of an encyclopedia. The eBook is rich with video, images, and text. It is narrated by Corwin.
Pledge to end wildlife trafficking for Wildlife Conservation Day
(12/04/2012) Today has been dubbed the first ever global Wildlife Conservation Day. To honor it, a coalition of conservation groups—including WWF and Wildlife Conservation Society (WCS)—are working to raise awareness of illegal wildlife trafficking. Poaching for traditional medicine, bushmeat, and other products has put innumerable species at risk, including tigers, rhinos, sharks, and elephants.
Could rebuilding global fisheries save hundreds of billions of dollars?
(11/26/2012) Global fisheries are gutting the world economy by US$13 billion annually, according to an economic analysis published July 13 in the journal PLoS ONE. National subsidies that encourage overfishing cause the most losses, the analysis claims. However, researchers believe that allowing fish stocks to rebuild and making fishing more efficient could reverse these losses, leading to net gains of US$600 to US$1,400 billion within 50 years. Such savings won’t come cheaply, the analysis suggests. Rebuilding fisheries worldwide could cost US$130 to US$292 billion, the researchers estimate. Most of the cost would go toward retraining or retiring nearly half of the world’s 35 million fisheries workers.
BP fined $4.5 billion for Gulf of Mexico oil spill, but company may spend more buying its own stocks
(11/19/2012) Last week the U.S. federal government fined BP $4.5 billion for the Deepwater Horizon disaster in 2010, which killed 11 workers and leaked nearly 5 million barrels of oil into the Gulf of Mexico. The oil giant also plead guilt to 12 felonies and two misdemeanors. However, even this fine—the largest in U.S. history—failed to dampen shareholder support of BP: stocks actually rose one percent following the announcement. Meanwhile, according to the Sunday Times, BP plans to spend $5.9 billion (over a billion more than the fine) buying back its own shares in order to boost stock prices.
Climate change threatens population of Earth’s largest sea turtle
(11/19/2012) A drier, hotter climate in Central America could wipe out the population of leatherback sea turtles from the eastern Pacific Ocean by the year 2100, according to a grim projection published on July 1 in Nature Climate Change. Already critically endangered from fisheries by-catch and historic egg poaching, leatherbacks can hardly accommodate another human-related threat. Yet scientists still hold out hope for interventions that could save the turtles.
Photos: Mozambique creates Africa's biggest marine protected area
(11/13/2012) Last week, the East African nation of Mozambique announced it was protecting 10,411 square kilometers (4,020 square miles) of coastal marine waters, making the new Marine Protected Area (MPA) the biggest on the continent. The protected area, dubbed the Primeiras and Segundas Archipelago ("First" and "Second" islands), includes ten islands as well as mangrove forests, rich coral reefs, and seagrass ecosystems.
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.
A new way to measure the ocean's health
(10/23/2012) A diverse array of institutions have come together to release a new, revolutionary ocean health assessment called the "Ocean Health Index." Researchers formed the index in order to gauge the health of the world’s oceans. The index is the result of a huge collaborative effort, including top researchers crossing a diverse range of disciplines such as the National Center for Ecological Analysis and Synthesis (NCEAS) and Conservation International.
Penguins face a slippery future
(09/26/2012) Penguins have spent years fooling us. With their image seemingly every where we turn—entertaining us in animated films, awing us in documentaries, and winking at us in commercials—they have made most of us believe they are doing just fine; the penguin's charming demeanor has lulled us into complacency about their fate. But penguin populations are facing historic declines even as their popularity in human society rises. Overfishing is decimating some of their prey species, climate change is shifting their resources and imperiling their habitat, meanwhile pollution, such as oil spills, are putting even healthy colonies at risk. Now, a young organization, the Global Penguin Society (GPS), is working to save all of the world's 18 penguin species by working with scientists, governments, and local communities.
Strangest island in the Caribbean may be a sanctuary for critically endangered coral
(07/16/2012) Don't feel bad if you‘ve never heard of Navassa Island, even though it's actually part of the U.S. according to the Guano Islands Act of 1856. This uninhabited speck between Haiti and Jamaica, barely bigger than New York City’s Central Park, has a bizarre and bloody history—and may be a crucial refuge for endangered coral in the Caribbean.
Indonesia eco-newswrap: farmers threaten to immolate themselves over plantation plan
(06/28/2012) Pulau Island farmers are threatening to immolate themselves after the Indonesian Ministry of Forestry has ignored their request to stop a part of their island from being converted into eucalyptus plantations by PT Riau Andalan Pulp and Paper. A letter from the farmers, who are members of the Riau Farmer Union, to Indonesian President Susilo Bambang Yudhoyono received no response, and the activists say 10 of them will travel to the presidential palace in Jakarta on June 25 and burn themselves alive in protest.
Cowards at Rio?: organizations decry 'pathetic' agreement
(06/20/2012) As world leaders head to Rio de Janeiro for the UN Summit on Sustainable Development, environmental and poverty groups are denouncing the last-minute text agreed on by dignitaries as "pathetic," (Greenpeace), a "damp squib" (Friends of the Earth), "a dead end" (Oxfam), and, if nothing changes, "a colossal waste of time" (WWF). "We were promised the 'future we want' but are now being presented with a 'common vision' of a polluter’s charter that will cook the planet, empty the oceans and wreck the rain forests,“ the head of Greenpeace, Kumi Naidoo, said. "This is not a foundation on which to grow economies or pull people out of poverty, it’s the last will and testament of a destructive twentieth century development model."
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.
Australia sets aside 40 percent of its waters for protection
(06/14/2012) In an announcement to coincide with the beginnings of the UN's Rio+20 Summit on Sustainable Development, Australia has announced ambitious plans to protect 3.1 million square kilometers (1.19 million square miles) of its ocean, including the Coral Sea. If enacted, the proposition will increase Australia's marine protected areas from 27 to 60, covering about 40 percent of Australia's waters.
Forgotten Species: the wonder-inducing giant clam
(06/11/2012) The first time I ever saw a giant clam was at a ride in Walt Disney World's Magic Kingdom. My family and I piled into the Nautilus submersible at the 20,000 Leagues Under the Sea: Submarine Voyage and descended into the playtime depths. While we saw sea turtles, sharks, lobsters, mermaids, and even a sea monster, the creature that lingered in my mind most was the giant clam, raising and closing its pearly shell in the weedy abyss. Of course, none of these aquatic wonders were real—they were animatronics—but to a child with a vivid imagination they stirred within me the deep mystery of the boundless ocean, and none more so than that monstrous clam with its gaping maw.
Regulations help fish, and fishermen, recover in the U.S.
(05/30/2012) Marine fish populations in the U.S. are generally recovering, according to a new report by the National Oceanic and Atmospheric Administration (NOAA). Last year six fish populations reached healthy levels in the U.S., boosting the total number of fish populations that have recovered to 27 since 2000. The success is due to the implementation of science-based annual catch limits which regulate how many fish are caught every year.
Nearly 2,000 fish species traded in U.S. tropical aquarium market
(05/24/2012) The U.S. tropical aquarium market poses problems and opportunities for conservation, according to a landmark study published in the open-access journal PLoS ONE. The study reviewed import records in the U.S. for one year (2004-2005) and found that over 11 million wild tropical fish from 1,802 species were imported from 40 different countries. While the number of fish species targeted surprised researchers, the total amount of fish imported was actually less than expected.
Seagrass beds store 20 billion tons of carbon
(05/22/2012) Just below the ocean's surface lies a carbon powerhouse: seagrass meadows. New research in Nature Geoscience estimates that the world's seagrass meadows conservatively store 19.9 billion metric tons of carbon, even though the threatened marine ecosystems make up only 0.2 percent of Earth's surface. The findings lend support to the idea that seagrass protection and restoration could play a major role in mitigating climate change.
Educating the next generation of conservation leaders in Colombia
(05/14/2012) Colombia's northern departments of Cordoba and Bolivar are home to an abundance of coral reefs, estuaries, mangroves forests, and forests. Rich in both marine and terrestrial wildlife, local communities depend on the sea and land for survival, yet these ecosystems are imperiled by booming populations, overexploitation, and unsustainable management. Since 2007, an innovative education program in the region, the Guardians of Nature, has worked to teach local children about the ecology of the region, hoping to instill a conservation ethic that will aid both the present and the future.
Featured video: the oceans and Rio+20
(05/10/2012) A new video by Pew Environment Group and the Zoological Society of London (ZSL) hopes to convince policy-makers attending the Rio+20 Summit on Sustainable Development this summer that urgent action is needed to save the ocean's from an environmental crisis.
World's smallest dolphin: only 55 left, but continue to drown in nets
(03/22/2012) The world's smallest dolphin is also the closest to extinction. New Zealand government figures show that Maui's dolphin (Cephalorhynchus hectori maui) are down to just 55 mature individuals, falling from 111 in 2005. The small cetaceans, measuring up to 1.7 meters (5.5 feet), are imperiled due to drowning in gillnets with the most recent death by a fisherman's net occurring in January.
Three U.S. retailers pledge to avoid fish from embattled Ross Sea
(03/14/2012) The Ross Sea, a massive bay off Antarctica, has been dubbed the world's last ocean due to its pristine state, long-untouched by industry and fisheries. However, over the last 15 years New Zealand commercial fisheries have entered the sea, seeking the slow-growing Antarctic toothfish which is usually sold as the high-end Chilean sea bass. Now as conservation groups plead for nations to grant the Ross Sea protected status, Greenpeace has begun a campaign to get good retailers to steer clear of stocking Antarctic toothfish. To date, Safeway, Wegmans, and Harris Teeter has all pledged not to source from the Ross Sea.
Camera traps go under the ocean, seeking sharks
(03/12/2012) Remote camera traps, which have become a hugely important conservation tool on land during the past decade, have now gone underwater. Marine biologists have used underwater video camera traps to compare the population of Caribbean reef sharks (Carcharhinus perezii) in Belize's protected areas versus fishing areas in a new study in the open-access journal PLoS ONE. Conducted from 2005-2010, the study found that reef sharks benefited significantly from conservation areas.
