(07/25/2014) Turtles comprise one of the oldest living groups of reptiles, with hundreds of species found throughout the world. Many have been well-researched, and scientists know very specific things about their various evolutionary histories, metabolic rates, and the ways in which their sexes are determined. But there was one very obvious thing that has been largely left unknown by science until very recently. Turtles can make sounds.
Scientists ask Australia to strengthen, not weaken, protection for Great Barrier Reef
(07/24/2014) A convening of nearly 600 tropical biologists and conservation scientists has called upon the Australian government to strengthen protection of the Australia's Great Barrier Reef. The declaration, issued at the annual meeting of the Association for Tropical Biology and Conservation (ATBC), comes as Prime Minister Tony Abbott pushes to allow industrial dumping in the Great Barrier Reef Marine Park as well as port development in a nearby coastal area.
Coastal wildlife paradise declared biosphere reserve in Argentina (PHOTOS)
(07/15/2014) Conservationists are celebrating the announcement that UNESCO has dubbed Argentina's Península Valdés a biosphere reserve under the Man and Biosphere Program (MBA). A hatchet-shaped peninsula that juts out into the Southern Atlantic Ocean, the world's newest biosphere reserve is home to a hugely-diverse collection of both terrestrial and marine wildlife.
A tale of two fish: cyanide fishing and foreign bosses off Sulawesi's coast (Part I)
(07/08/2014) In spring and summer, after the monsoon storms have passed, the fishing boats set out again from tiny Kodingareng Island in the Spermonde Archipelago off the coast of South Sulawesi. In the afternoon heat, Abdul Wahid joins his fellow fishermen in the narrow shade of the beachfront village houses to check out the daily fish prices.
Booming populations, rising economies, threatened biodiversity: the tropics will never be the same
(07/07/2014) For those living either north or south of the tropics, images of this green ring around the Earth's equator often include verdant rainforests, exotic animals, and unchanging weather; but they may also be of entrenched poverty, unstable governments, and appalling environmental destruction. A massive new report, The State of the Tropics, however, finds that the truth is far more complicated.
Super warm oceans make May the hottest on record
(06/26/2014) Last month was the warmest May on record, according to new data from the National Oceanic and Atmospheric Administration (NOAA). While global land surface temperatures were the fourth warmest, it was the ocean surface where things really heated up.
Dying for Fiji's Sea Cucumbers
(06/23/2014) Redfish, Greenfish, Blackfish. Pinkfish, Curryfish, Lollyfish. They sound like Dr. Seuss characters and certainly look like they should be. Yet these sausage-shaped, rubbery animals stippled in fleshy bumps are not fish at all, but an invertebrate in the group that includes sea stars, sea urchins and sand dollars. Sea cucumbers, referred to as 'bêche-de-mer' or 'trepang' when sold as dried food have a high value - an individual in Fiji can fetch about $80 US.
U.S. raises $800 million for oceans, including $7 million from Leonardo DiCaprio
(06/19/2014) A U.S. State Department conference on the oceans raised an impressive $800 million for marine conservation this week. The conference was also notable for the announcement by President Obama of an intent to significantly expand the Pacific Remote Islands Marine National Monument.
Bigger than Mexico? Obama announces major expansion of Pacific protected area
(06/18/2014) President Obama announced yesterday he intends to drastically expand the Pacific Remote Islands Marine National Monument making what will likely be the largest marine protected area on the planet. While the full extent of the ocean park has yet to be determined, it could potentially protect over two million square kilometers, an area larger than Mexico.
By the bones: herring populations were superabundant before commercial fisheries
(06/09/2014) Scientists analyzed almost half a million fish bones to shed light on the population history of Pacific herring (Clupea pallasii) in the North Pacific Ocean. Their paper reveals a decline of unprecedented scale, and suggests that while the abundance of Pacific herring does fluctuate naturally, their numbers have fallen precipitously since commercial fishing started targeting the species in the 19th century.
New study finds environmental damage globally may cost more than U.S. GDP
(06/06/2014) A new study added up all the world’s ecosystem services – from carbon storage and crop pollination, to recreation and flood mitigation – and found, every year, nature provides $145 trillion in benefits. It also indicates that land use changes, most of which has been caused by humans, may be reducing these benefits by trillions of dollars every year.
Trawling: destructive fishing method is turning seafloors to 'deserts'
(05/28/2014) Previous research has linked trawling to significant environmental impacts, such as the harvest of large numbers of non-target species, collectively termed “bycatch,” as well as destruction of shallow seabeds. Now, a new study finds this method is also resulting in long-term, far-reaching consequences in the deeper ocean and beyond.
Extreme cold and drought in U.S. linked to climate change
(05/23/2014) The U.S. Midwest and Northeast experienced one of the coldest, snowiest winters on record this past season. This might seem contrary to warming trends forecast by climate scientists, but a new analysis released today in Science points out that climate change caused by greenhouse gas emissions may actually have contributed to the well-below average temperatures seen in parts of the U.S.
Olinguito, tinkerbell, and a dragon: meet the top 10 new species of 2013
(05/22/2014) Out of around 18,000 new species described and named last year, scientists have highlighted ten in an effort to raise awareness about the imperiled biodiversity around us. Each species—from a teddy-bear-like carnivore in the Andes to a microbe that survives clean rooms where spaceships are built—stands out from the crowd for one reason or another.
Former Miss South Pacific steps into new conservation role
(05/15/2014) Alisi Rabukawaqa, an articulate, vibrant, 26-year-old Fijian known in Oceania as Miss South Pacific 2011, has set her sights on a novel conservation program in Fiji. The Conservation Officer program, created in 2013, supports natural resource management within villages in Fiji and links them with the government arm overseeing the needs of indigenous Fijians. Mongabay.org Special Reporting Initiative Fellow Amy West sits down for an interview.
Scientists uncover new marine mammal genus, represented by single endangered species
(05/14/2014) This is the story of three seals: the Caribbean, the Hawaiian, and the Mediterranean monk seals. Once numbering in the hundreds of thousands, the Caribbean monk seal was a hugely abundant marine mammal found across the Caribbean, and even recorded by Christopher Columbus during his second voyage, whose men killed several for food.
NASA data: 1997 all over again for Indonesia?
(05/14/2014) The latest data from NASA shows that conditions developing in the tropical Pacific are eerily similar to those in 1997, when El Niño wreaked havoc across Indonesia, spurring a severe drought that exacerbated massive peatland and forest fires which spread choking haze across much of South and Southeast Asia.
Coral could prevent HIV: newly discovered protein blocks infection
(05/09/2014) In the waters off the coast of northern Australia lives a species of feathery coral. Years ago, bits of it were collected by the Australian Institute of Marine Science and stored at the National Cancer Institute’s extract repository, along with 200,000 other samples. Researchers retrieved and tested this coral sample, and recently reported that it was very effective at blocking HIV infection of host cells.
Underwater horrors: shells of marine life melting off the coast of the U.S.
(05/08/2014) It could be the plot of a horror movie: humans wake up one day to discover that chemical changes in the atmosphere are dissolving away parts of their bodies. But for small marine life known as sea butterflies, or pteropods, this is what's happening off the West Cost of the U.S. Increased carbon in the ocean is melting away shells of sea butterflies.
New Caledonia officially creates world's largest protected area (photos)
(05/02/2014) The government of New Caledonia last week officially created the world's largest protected area, establishing a multi-use zone that at 1.3 million square kilometers is three times the size of Germany, reports Conservation International (CI).
Japan changes its mind about Antarctic whaling ban, plans to continue hunts in 2015
(04/25/2014) Conservation groups were jubilant in response to last month's ruling by the International Court of Justice (ICJ) banning Japan's long-standing "research" whaling practices in the Antarctic. However, the celebrations proved short-lived after news last week that Japan has rescinded its agreement to abide by the ruling and stop whaling altogether, opting instead to redesign its program and continue whale hunts in the Southern Ocean.
Weird and mysterious: scientists find new shark species
(04/16/2014) A long snout with teeth jutting from the sides? Check. Catfish-like barbels dangling from its chin? Got them. Gills on the side of its body? It has those, too. These are characteristics of a bizarre group of sharks known as sawsharks. And until recently, only seven species were recognized. However, a new discovery raises that number by one more.
Collateral damage: new findings shed light on the full impact of commercial fishing
(04/09/2014) Aside from reducing the populations of the species sought for capture, commercial fisheries are also killing thousands of nontarget creatures such as sharks, albatross, and sea turtles, collectively referred to as “bycatch.” However, the full extent of the problem is only beginning to be grasped.
Extinction crisis: rising sea levels will submerge thousands of islands
(04/08/2014) Sea levels are rising at the highest rate in thousands of years, putting at risk low-lying islands around the world. In a new study published in Nature Conservation, researchers found that projected rises in sea level stand to swamp more than 10,000 islands, displacing human communities and wiping many unique species off the face of the earth.
Is 20 millions tons enough? Scientists recommend plastic crackdown as oceans choke
(04/02/2014) Every year, 20 million tons of plastic enters the world’s oceans. In 2012, the Rio +20 United Nations Conference on Sustainable Development dubbed marine plastic litter “a major environmental issue that the world must address,” and asked for management action by 2025.
Apocalypse now? Climate change already damaging agriculture, acidifying seas, and worsening extreme weather
(03/31/2014) It's not just melting glaciers and bizarrely-early Springs anymore; climate change is impacting every facet of human civilization from our ability to grow enough crops to our ability to get along with each other, according to a new 2,300-page report from the Intergovernmental Panel on Climate Change (IPCC). The massive report states definitively that climate change is already affecting human societies on every continent.
Revealed for the first time: the surprising biodiversity of algae 'reefs'
(03/28/2014) Most people are familiar with coral reefs, but very few have ever heard of their algal equivalent – rhodolith beds. Yet, these structures provide crucial habitat for many marine species. In the first study of its kind, published in mongabay.com’s Tropical Conservation Science, researchers unveil just how important these beds are for bottom-dwelling organisms, and the species that depend on them.
3 environmental reporting prize winners to explore drivers of deforestation, community forestry, and sustainable seafood in China
(03/19/2014) Mongabay.org, the non-profit arm of environmental science web site Mongabay.com, has selected winners of three environmental reporting prizes under its Special Reporting Initiatives (SRI) program. The three prizes, which were launched in January, explore the impacts of rising human consumption on forest and marine ecosystems. The winners, selected from more than 150 applicants by a panel of issue-area experts, include Robert S. Eshelman, Ruxandra Guidi and Bear Guerra, and Dominic Bracco II and Erik Vance.
A Turtle's Tale: researchers discover baby turtles' kindergarten (photos)
(03/14/2014) Kate Mansfield, at her lab in the University of Central Florida, is holding a baby loggerhead turtle, smaller than her palm, painting manicure acrylic on its shell. When the base coat dries out, she glues on top a neoprene patch from an old wetsuit with hair extensions adhesive. Finally, she attaches a satellite tracker on top, the size of a two "party cheese" cubes, with flexible aquarium silicone, powered by a tiny solar battery. Now the little turtle is ready to be released back into the ocean.
Scientists spy on whales from space
(03/11/2014) Although whales are the biggest animals on the planet, scientists have found in difficult to count them. But a new study in PLOS ONE may change this: researchers tested the idea of counting whales using high resolution satellite imagery. Employing a single image from the WorldView2 satellite, scientists went about counting a pod of southern right whales in the Golfo Nuevo off the coast of Argentina.
Does haze from burning forests affect marine life?
(03/10/2014) Two scientists are calling on researchers, NGOs, and governments to begin studying the impact of burning forests and peatlands in Indonesia on the already-threatened marine ecosystems of Southeast Asia. Every year, Indonesian farmers set forests, vegetation, and peatlands alight to clear them for agriculture, often palm oil, and pulp and paper plantations. Not only do these practices destroy hugely-diverse tropical forests, but the resulting haze spreads to many parts of Southeast Asia, threatening regional health and impacting economies. Now, a new paper argues that the sinister impacts of Indonesia's burning may extend as far as the oceans.
Offshore wind farms could blunt hurricane damage
(02/28/2014) Massive offshore wind turbine arrays would reduce hurricane wind speeds and storm surge, reports a study published this week in Nature Climate Change. And while the size (tens of thousands of turbines) and cost (hundreds of billions of dollars) is difficult to imagine, the reduction in storm damage and value of electricity produced would effectively bring the price tag to zero according to the study authors.
Wonderful Creatures: the tiny, predatory penis-worm that lies in wait in the sand
(02/28/2014) The seabed is really where it’s at in terms of animal diversity. Of the 35 known animal lineages, representatives of all but two are found here. In contrast, the huge numbers of species that inhabit tropical rainforests represent a mere 12 lineages. One group of animals that illustrates the diversity of the seabed is the Priapulida, which also go by the unfortunate common name of "penis worms." Only 20 species of priapulid are known today, a shadow of their diverse past, which extends back for well over 500 million years. Not commonly seen, the priapulids have attracted little attention from the zoology community as a whole.
Saving sharks one sandwich at a time: conservationists target 'shark bake'
(02/28/2014) Thousands of Carnival revelers in Trinidad wouldn't think of missing the chance to go to Maracas Beach, the most famous strip of sand on the small Caribbean island off the northeast coast of Venezuela. Beachgoers might not think twice about eating a favorite food called "shark bake" either – at least, until now. But this week, conservationists launched a shark-saving campaign timed to get maximum exposure out of the celebration that will bring throngs of visitors to the island.
Plastic waste ingested by worms threatens marine food chains
(02/26/2014) Small fragments of plastic waste are damaging the health of lugworms, putting a key cog in marine ecosystems at risk. Published in Current Biology, a new study by scientists at the University of Exeter and the University of Plymouth shows the impact of microplastics on the marine worms' health and behavior.
Corals thriving despite acidified conditions in remote Pacific bay
(02/25/2014) Scientists have discovered a small island bay in the Pacific which could serve as a peephole into the future of the ocean. Palau's Rock Island Bay harbors a naturally occurring anomaly – its water is acidified as much as scientists expect the entire ocean to be by 2100 as a result of rising carbon dioxide emissions.
Ocean acidifying 10 times faster than anytime in the last 55 million years, putting polar ecosystems at risk
(02/24/2014) An assessment of ocean acidification, presented at the UN Climate Change Conference in Warsaw in November 2013, starkly concluded that acidity is on track to rise 170 percent by the end of this century. As many key species are sensitive to changes in acidity, this would drastically impact ocean ecosystems, with effects especially pronounced in polar regions where the cold waters intensify acidification, and which are home to many organisms that are particularly vulnerable to acidification.
Indonesia pledges to protect manta rays
(02/21/2014) In a move signaling their commitment to CITES agreements on international trade of plants and animals, the Indonesian government declared two species of manta ray 'protected' under Indonesian law. Decree Number 4/KEPMEN-KP/2014 issued by Ministry of Maritime Affairs and Fisheries states that two manta ray species, Manta birostris and Manta alfredi, now enjoy full protection throughout their entire life cycle. The decree explicitly extends that protection to all parts of their body.
Scientists discover new whale species
(02/14/2014) Beaked whales are incredibly elusive and rare, little-known to scientists and the public alike—although some species are three times the size of an elephant. Extreme divers, beaked whales have been recorded plunging as deep as 1,800 meters (5,900 feet) for over an hour. Few of the over 20 species are well-known by researchers, but now scientists have discovered a new beaked whale to add to the already large, and cryptic, group: the pointed beaked whale (Mesoplodon hotaula).
Wonderful Creatures: the bizarre-looking marine worm with an incredibly important ecological role
(02/13/2014) Almost everyone knows what an earthworm is, but these very familiar animals are just one variation on a very rich theme that is at its most fabulously varied in the oceans. The mind-boggling appearances and lifestyles of the marine segmented worms are perfectly exemplified by this week's animal.
Incredible encounter: whales devour European eels in the darkness of the ocean depths
(02/11/2014) The Critically Endangered European eel makes one of the most astounding migrations in the wild kingdom. After spending most of its life in Europe's freshwater rivers, the eel embarks on an undersea odyssey, traveling 6,000 kilometers (3,720 miles) to the Sargasso Sea where it will spawn and die. The long-journeying eels larva than make their way back to Europe over nearly a year. Yet by tracking adult European eels (Anguilla anguilla) with electronic data loggers, scientists have discovered that some eels never make it to their spawning ground, but instead are swallowed-up in the depths by leviathans.
Study: 59% of Marine Protected Areas are ineffective
(02/10/2014) Protecting large, isolated areas of no-take zones for over 10 years with strong enforcement is the key to effective Marine Protected Areas (MPAs), according to a letter published this week in Nature. However, 59% of all MPAs meet less than three of the five criteria, making them protected in name only.
35 pictures of the sharkfin trade that will shock and dismay you
(02/07/2014) Last month scientists released a study warning that one quarter of all sharks and rays are threatened with extinction. The research was the result of collaboration between 300 scientists from 64 countries. It concluded that overfishing is the biggest threat to the most number of species, noting that up to 73 million sharks are killed each year for their fins alone.
Scientists discover new eagle ray imperiled by Japanese pest program (photos)
(01/30/2014) Scientists have described a new species of eagle ray in the northwest Pacific Ocean, which they have named "narutobiei" (Aetobatus narutobiei) after its local name in Japan. While the new species has long been known by scientists, it was clumped together with the longheaded eagle ray (Aetobatus flagellum) for over two hundred years. Splitting the two species has large-scale conservation impacts, according to the paper describing the new species in PLOS ONE.
Wonderful Creatures: meet the animal that has evolved a cushy, worry-free life inside an octopus
(01/30/2014) The range of habitats that animals have come to occupy is nothing short of staggering. Take the dicyemids for example. They are among the simplest animals on the planet, with a tiny, worm-like adult body that consists of between 10 and 40 cells. They have no organs, body cavities or even guts—a structural simplicity which is a consequence of where and how they live. The only place you will find adult dicyemids is inside the bodies of cephalopods, typically octopuses and cuttlefish where large numbers of them cling to the inner wall of the mollusc's kidney.
Shell drops plans to drill in the Arctic for now
(01/30/2014) Facing plunging profits, Royal Dutch Shell has announced it will cut exploration and development funding by nearly $10 billion this year, including halting their long-suffering plans to drill in the Arctic ocean. Shell's new CEO, Ben van Beurden, made the announcement yesterday that controversial plans to drill off the Alaskan coast will be put on hold for another year.
Investigation finds Chinese factory slaughters 600 whale sharks a year
(01/29/2014) A four-year investigation by WildLifeRisk, a Hong Kong-based marine conservation group, has found that a single factory in China’s Zhejiang Province slaughters some 600 whale sharks a year to produce oil for cosmetics and health supplements.
One quarter of sharks and rays threatened with extinction
(01/22/2014) One quarter of all shark and ray species are threatened with extinction, according to a new study published in the open-access journal eLife. The paper analyzed the threat and conservation status of 1,041 species of chondrichthyans—the class of fish whose skeletons are made of cartilage instead of bone which includes sharks, rays, skates and chimaeras—and found this group to be among the most threatened animals in the world.
Photos: Japanese fishermen slaughter 41 dolphins, capture 52 in 'The Cove'
(01/21/2014) The annual dolphin hunt in Taiji, Japan ended on Monday with dozens being slaughtered for meat and captured for sale to amusement parks, reports Sea Shepherd, an ocean activist group that campaigns against the practice and just released photos documenting the weekend's harvest.
Underestimating global warming: gaps in Arctic temperature data lead scientists and public astray
(01/15/2014) No place on Earth is heating up faster than the Arctic, but just how fast has remained an open question due to large gaps in temperature data across the vast region. Now, a recent study in the Quarterly Journal of the Royal Meteorological Society finds that not only is the Arctic warming eight times faster than the rest of the planet, but failure to account for temperature gaps has led global datasets to underestimate the rise of temperatures worldwide.
PHOTOS: Glowing fish - study finds widespread biofluorescence among fish
(01/10/2014) Biofluorescence is widespread among marine fish species, indicating its importance in communication and avoiding detection, finds a new study published in the journal PLOS ONE. The research shows that biofluorescence — a phenomenon where organisms absorb light, transform it, and emit it as a different color — is more common in the animal kingdom than previously known.
Japanese whale hunt stopped, for now
(01/06/2014) Anti-whaling group Sea Shepherd said its fleet of ships has successfully disrupted the annual Japanese whale hunt in the waters off Antarctica.
Global warming could upset Antarctic food chain
(01/02/2014) Resting near the bottom of the foodchain, Antarctic krill (Euphausia superba) underpin much of the Southern Ocean's ecosystem. But in a rapidly warming world, these hugely-abundant crustaceans could see their habitat shrink considerably. In a recent paper in PLOS ONE, scientists predict that Antarctic krill could lose 20 percent of their growth habitat, or 1.2 million square kilometers.
World first: Russia begins pumping oil from Arctic seabed
(12/23/2013) Oil has begun to be pumped from the Arctic seabed, according to Russian oil giant, Gazprom. The company announced on Friday that it has begun exploiting oil reserves at the offshore field of Prirazlomnoye. The project, which is several years behind schedule, is hugely controversial and made international headlines in September after Russian military arrested 28 Greenpeace activists protesting the operation along with a British journalist and Russian videographer.
Top 10 HAPPY environmental stories of 2013
(12/19/2013) China begins to tackle pollution, carbon emissions: As China's environmental crisis worsens, the government has begun to unveil a series of new initiatives to curb record pollution and cut greenhouse emissions. The world's largest consumer of coal, China's growth in emissions is finally slowing and some experts believe the nation's emissions could peak within the decade. If China's emissions begin to fall, so too could the world's.
Top 10 Environmental Stories of 2013
(12/10/2013) 1. Carbon concentrations hit 400ppm while the IPCC sets global carbon budget: For the first time since our appearance on Earth, carbon concentrations in the atmosphere hit 400 parts per million. The last time concentrations were this high for a sustained period was 4-5 million years ago when temperatures were 10 degrees Celsius higher. Meanwhile, in the slow-moving effort to curb carbon emissions, the Intergovernmental Panel on Climate Change (IPCC) crafted a global carbon budget showing that most of the world's fossil fuel reserves must be left untouched if we are to avoid catastrophic climate change.
China bans shark fin, bird's nest soup from state banquets
(12/10/2013) China has banned shark fin and bird's nest soup from being served at official state banquets, reports Chinese state media.
Animal Earth: exploring the hidden biodiversity of our planet
(12/03/2013) Most of the species on Earth we never see. In fact, we have no idea what they look like, much less how spectacular they are. In general, people can identify relatively few of their backyard species, much less those of other continents. This disconnect likely leads to an inability in the general public to relate to biodiversity and, by extension, the loss of it. One of the most remarkable books I have read is a recent release that makes serious strides to repair that disconnect and affirm the human bond with biodiversity. Animal Earth: The Amazing Diversity of Living Creatures written by Ross Piper, a zoologist with the University of Leeds, opens up the door to discovery.
Google Earth reveals fish catch is 6 times greater than thought in Persian Gulf
(11/27/2013) Google Earth has once again been used by researchers for scientific discovery.
Leatherback sea turtle no longer Critically Endangered
(11/26/2013) The leatherback sea turtle—the world's largest turtle and the only member of the genus Dermochelys—received good news today. In an update of the IUCN Red List, the leatherback sea turtle (Dermochelys coriacea) has been moved from Critically Endangered to Vulnerable. However, conservationists warn that the species still remains hugely endangered—and in rapid decline—in many parts of its range.
Gulf of Mexico deep sea may need decades to recover from oil spill
(11/20/2013) The catastrophic explosion that spewed some five million barrels of oil deep into the Gulf of Mexico in April 2010 will take a heavy toll in the ocean’s lowest layers for years to come. That’s the stark conclusion of seafloor research conducted six months after the Deepwater Horizon oil spill. The study, published on August 7 in PLoS ONE, examined life in the Gulf’s deepest waters near the blowout, about 1.6 kilometers below the surface. Here, the researchers found that the damages will take decades to reverse.
Coelacanths might be monogamous, to the surprise of researchers
(11/14/2013) They evaded humans for millions of years and live very private lives. The hulking, fleshy-finned fish known as the coelacanth has beguiled scientists for generations. But the coelacanth mystique that enchants researchers also makes it difficult to study. Researchers recently revealed in Nature Communications one startling aspect of the coelacanth lifestyle: they might be monogamous.
Longline fisheries in Costa Rica hook tens of thousands of sea turtles every year
(11/14/2013) Hundreds of kilometers of commercial fishing lines slither along coastal waters in Costa Rica, hooking thousands of mahi-mahi and many other marketable fish. But when scientists scrutinized fishermen’s catch, they were shocked by the staggering number of sea turtles accidentally snagged on the lines.
Fishermen get crafty to circumvent shark fin ban
(11/10/2013) Authorities in Costa Rica have identified a new method used by fishermen to circumvent a ban on killing sharks for their fins. According to an INTERPOL alert, fishermen are now leaving a band of skin to keep the fin attached to the spine when they kill sharks. This approach takes advantage of an apparent loophole in regulations governing the shark fin trade.
DNA tests reveal new dolphin species (photos)
(10/30/2013) With the help of DNA tests, scientists have declared a new dolphin species that dwells off the coast of northern Australia. The discovery was made after a team of researchers looked at the world's humpback dolphins (in the genus Sousa), which sport telltale humps just behind their dorsal fins. While long-known to science, the new, as-yet-unnamed species was previously lumped with other humpback dolphins in the Indo-Pacific region.
98% of marine fish headed for the aquarium trade die within a year in the Philippines
(10/22/2013) Almost all wild caught marine fish for the aquarium trade will die within a year of capture, according to WWF. Following months of interviews with Filipino marine exporters and hobbyists, WWF-Philippines have found that roughly 80% of all marine fish die before they are sold, and those that survive long enough to be bought by hobbyists are extremely likely to be dead in under a year.
The 'dead' ocean: eyewitness says overfishing has emptied the Pacific
(10/22/2013) An Australian sailor has described parts of the Pacific Ocean as "dead" because of severe overfishing, with his vessel having to repeatedly swerve debris for thousands of kilometers on a journey from Australia to Japan. Ivan MacFadyen told of his horror at the severe lack of marine life and copious amounts of rubbish witnessed on a yacht race between Melbourne and Osaka. He recently returned from the trip, which he previously completed 10 years ago.
Global warming could shift tropical rainfall
(10/21/2013) Ongoing burning of fossil fuels could flip which portion of the tropics receive more rainfall: the southern hemisphere or the northern. Currently, the northern hemisphere tropics is the wetter of the two, but why this is has long baffled scientists. Now, new research in Nature Geoscience has discovered that rainfall in the tropics is in part driven by massive ocean currents that travel back-and-forth between the Arctic and Antarctic, a process known as ocean overturning circulation.
Another 'sea-serpent' oarfish washes up in California
(10/20/2013) Another sea-serpent-like oarfish has been found dead along the coast in Southern California
California 'sea monster' is an oarfish
(10/16/2013) The dead "sea monster' spotted off the coast of Southern California on Sunday is actually an oarfish, a deepwater fish species that can reach a length of 55 feet (17 meters).
California celebrates its inaugural Pacific Leatherback Conservation Day with sobering reality
(10/15/2013) On an isolated beach in Bird’s Head Peninsula, Indonesia, a female leatherback turtle shuffles out of the ocean and onto the shore, ready to lay her eggs. Under the cover of night she excavates a hole in the sand, depositing anywhere from 80 to 100 eggs inside. Using her flippers she flicks sand over the eggs, hiding them from potential predators. Then, shuffling away, she returns to the turquoise waters ready to make an 8,500-mile journey across the Pacific Ocean to the California coast.
Russia charges non-violent activists with 'piracy' for protesting Arctic oil drilling
(10/07/2013) In what is being described by Greenpeace as an 'imaginary offense,' Russia has charged 30 people with piracy after activists protested against oil exploitation in the Arctic. The 30 charged included not only protestors, but a British journalist and Russian videographer who were on board Greenpeace's ship, the Arctic Sunrise, when it was stormed by the Russian military late last month.
Governments should respond to ocean acidification 'as urgently as they do to national security threats'
(10/03/2013) The oceans are more acidic now than they have been for at least 300m years, due to carbon dioxide emissions from burning fossil fuels, and a mass extinction of key species may already be almost inevitable as a result, leading marine scientists warned on Thursday. An international audit of the health of the oceans has found that overfishing and pollution are also contributing to the crisis, in a deadly combination of destructive forces that are imperiling marine life, on which billions of people depend for their nutrition and livelihood.
Sonar used by oil company caused mass whale stranding in Madagascar
(09/25/2013) An oil company's use of a high-frequency mapping sonar system was responsible for a mass whale stranding in northwest Madagascar in 2008, finds a new report.
Russian military raids Greenpeace ship, hold activists captive

Shark overfishing hurts coral reefs
(09/20/2013) Overfishing for sharks is having detrimental effects on coral reefs, finds a new study published in the journal PLOS One.
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.
Natural cooling cycle in Pacific may have slowed global warming...for now
(09/12/2013) Cooling waters in the tropical Pacific Ocean appear to be a major factor in dampening global warming in recent years, scientists said on Wednesday. Their work is a big step forward in helping to solve the greatest puzzle of current climate change research – why global average surface temperatures, while still on an upward trend, have risen more slowly in the past 10 to fifteen years than previously.
Video: scientists discover new walking shark species in Indonesia
(09/11/2013) A species of shark that uses its fins to 'walk' along the bottom of the ocean floor has been discovered off the coast of Indonesia. The shark, Hemiscyllium halmahera, uses its fins to wiggle along the seabed and forage for small fish and crustaceans, scientists from Conservation International said on Friday.
Finding a needle in a haystack: two new species of octocorals discovered in the Pacific Ocean
(09/04/2013) The vast expanse of the Earth's oceans makes finding a new species like finding a needle in a haystack. In fact, finding a needle in a haystack may be easier than finding a new species of octocoral in the Pacific Ocean. But Gary Williams with the California Academy of Sciences has recently found not only one but two new species, including a new genus of octocoral.
Are sea turtles responsible for lower fish catches in India?
(08/29/2013) Fishing communities on Agatti Island in Lakshwadeep, India, blame their reduced fish catch on green turtles; according to them, green turtles chomp their way through the seagrass beds lining the shallow reef waters that are essential for fish to breed. This leads some in the community to clandestinely kill sea turtles and destroy their nests.
Bad feedback: ocean acidification to worsen global warming
(08/28/2013) As if ocean acidification and climate change weren't troubling enough (both of which are caused by still-rising carbon emissions), new research published in Nature finds that ocean acidification will eventually exacerbate global warming, further raising the Earth's temperature.
Eighty sea turtles wash up dead on the coast of Guatemala
(08/27/2013) An assortment of marine animals and birds reside along the black volcanic sand beaches of Guatemala’s Pacific coast, but lately both residents and visitors on the southeast beaches of the country have observed a tragic event – the stranding of dead sea turtles. Eighty dead sea turtles have been recorded since the first week of July.
Whale shark mapping: scientists uncover global distribution for the largest fish in the world
(08/27/2013) Polka-dotted and striped. Massive but docile. That’s the whale shark for you - the largest fish and shark in the world. But despite being major tourist attractions, the lives of these awe-inspiring creatures of the ocean remain far from being demystified. However, a team of researchers from Australia may now have some answers to where these whale sharks (Rhinocodon typus) occur.
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.
Climate change scattering marine species
(08/08/2013) Rising ocean temperatures are rearranging the biological make-up of our oceans, pushing species towards the poles by 7kms every year, as they chase the climates they can survive in, according to new research. The study, conducted by a working group of scientists from 17 different institutions, gathered data from seven different countries and found the warming oceans are causing marine species to alter their breeding, feeding and migration patterns.
U.S. bombs Great Barrier Reef, promises 'rapid recovery' of armaments
(07/23/2013) Four unarmed bombs dropped by the US military into the Great Barrier Reef Marine Park pose a low risk to wildlife and a joint mission will aim for their "rapid recovery", according to the government agency in charge of the reef. The Great Barrier Reef Marine Park Authority said two of the bombs are inert, containing concrete, while the other two were not armed, making the chance of detonation "extremely low".
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.
Hurricane intensity, frequency to increase with climate change
(07/08/2013) Warmer ocean temperatures will increase the frequency and intensity of tropical cyclones, typhoons and hurricanes in "most locations" this century, concludes a new study based on simulations using six global climate models.
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.
Australia aims to end Japan's whaling
(06/27/2013) Australia is hoping to put a permanent end to Japan's annual slaughter of hundreds of whales in the Southern Ocean, in a landmark legal challenge that begins this week. Australia, a vocal opponent of Japan's annual "scientific" hunts in the Antarctic, says it is confident that the international court of justice (ICJ) in The Hague will outlaw the hunts at the end of a highly anticipated case that is due to start on Wednesday.
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.
Monster shark sparks talk of overfishing
(06/06/2013) A giant mako shark caught by a sports-fisherman Monday in California has spurred a conversation about declining shark populations worldwide, reports the Associated Press.
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.
Whales teach each other new feeding behavior
(05/29/2013) Humpback whales (Megaptera novaeangliae), popularly known for their majestic and alluring underwater mating songs and acrobatic breaches, have shown that they can adapt to changing prey variability by passing on new hunting techniques to each other. According to new findings in the journal Science, a team of researchers have revealed the cultural spread of new hunting techniques through a population of humpback whales over the span of 27 years.
Famed bird reappears after 400,000 miles of flight
(05/22/2013) A migratory shorebird that has flown more than 400,000 miles has reappeared once again.
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.
Pacific islanders are the 'victims of industrial countries unable to control their carbon dioxide emissions'
(05/15/2013) With islands and atolls scattered across the ocean, the small Pacific island states are among those most exposed to the effects of global warming: increasing acidity and rising sea level, more frequent natural disasters and damage to coral reefs. These micro-states, home to about 10 million people, are already paying for the environmental irresponsibility of the great powers.
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.
