(10/29/2014) Catching older fish may impact a school's ability to migrate from spawning grounds to feeding areas, according to a recent study published in the Journal of the Royal Society Interface. The study’s scientists believe that fish schools may retain a collective memory, a communal mind map of sorts, which help these groups reach their destinations, some of which are thousands of miles away.
Behind on biodiversity targets, govts pledge to increase funding for conservation
(10/17/2014) On the heels of a report showing that the world is far behind on targets to halve habitat loss, cut pollution, and reduce overfishing, delegates meeting at a United Nations conference in Pyeongchang, South Korea have agreed to increase step up efforts to conserve biodiversity in developing nations.
Greenpeace sinks Lego's $116 million deal with Shell Oil over Arctic drilling
(10/09/2014) Lego has announced it will be severing its partnership with the oil giant, Shell, when the current contract expires after a clever campaign by environmental activist group, Greenpeace. Since 2011, Lego has been selling exclusive sets at Shell stations, but the companies' relationship actually goes back decades. In 1966, the Danish toy company first began selling Lego sets with Shell's brand stamped on them.
Saving Peru's sea turtles and marine birds: conservationists and fishermen partner to tackle bycatch
(10/07/2014) Marine conservationists often view fisheries as an enemy of sorts, vacuuming up fish with little thought to the long-term consequences and using equipment that also ends up killing other species, i.e. bycatch like sea turtles and marine birds. However, Joanna Alfaro Shigueto, the President of the Peruvian NGOProDelphinus and winner of a 2012 Whitley Award, has chosen a different tact.
Throng of 35,000 walruses is largest ever recorded on land, sign of warming arctic
(10/01/2014) A mass of thousands of walruses were spotted hauled up on land in northwest Alaska during NOAA aerial surveys earlier this week. An estimated 35,000 occupied a single beach – a record number illustrating a trend in an unnatural behavior scientists say is due to global warming.
Officials bust one of the biggest players in illegal Indonesian manta ray trade
(10/01/2014) Writing this from a hotel room in Indonesia’s second-largest city, Surabaya, I realize that I am filled with trepidation as I wait for the phone next to me to ring. When it does, the voice on the other end will tell me it’s go time; the culmination of many years of work towards ending the global trade in manta ray gills.
Is there hope for the vaquita? IUCN calls for action to save world's smallest, rarest porpoise
(09/19/2014) Since the baiji was declared extinct in the early aughts, the vaquita has taken its unenviable position as the world’s most threatened cetacean. The tiny porpoise currently numbers around 100, with accidental entanglement in gillnets primarily responsible for its decline. In response, the IUCN recently issued a statement calling for immediate action to curb vaquita bycatch and head off its extinction – which otherwise may lie just around the corner.
'We are running out of time': CO2 concentrations in the atmosphere surprise scientists
(09/10/2014) The concentration of carbon dioxide in the atmosphere made the biggest jump last year since 1984, according to the World Meteorological Organization's (WMO) Greenhouse Gas Bulletin, raising alarm bells about society's inaction on curbing global warming.
Norway slaughters over 700 whales this season
(09/08/2014) As of late August, Norway has killed 729 northern minke whales (Balaenoptera acutorostrata) during its annual whaling season, the highest number taken since 1993.
California blue whales recover to historical levels
(09/05/2014) The population of blue whales in the Eastern Pacific has recovered to 97 percent of historic levels decades after Earth's largest animal was nearly driven to extinction in some places due to the whaling industry, reports a new study published in the journal, Marine Mammal Science.
Australia cancels plan to dump dredge in Great Barrier Reef
(09/02/2014) A consortium of companies—North Queensland Bulk Ports, GVK Hancock and Adani Group—have announced they are giving up on a hugely-controversial plan to dump five million tonnes of dredged sediment in the Great Barrier Reef. The plans ran into considerable opposition from environment, conservation, and tourism groups who feared harm to the world's largest coral reef system.
Invasion of the lionfish: new research finds the situation may be worse than we thought
(08/27/2014) You may have recently read the controversial story on invasive lionfish research involving Dr. Zack Jud of Florida International University and a young girl named Lauren Arrington. While the issue of attribution in scientific research is crucial to the discipline, much of the media focus so far has sidestepped the real issue: what lionfish tolerance for brackish water really means for the environment.
Featured video: new Netflix documentary highlights the work of Sylvia Earle to save the oceans
(08/25/2014) Sylvia Earle is one of the ocean's staunchest defenders. A National Geographic Society Explorer in Residence and former chief scientist with NOAA, Earle has spent a lifetime documenting the rapid decline of the world's oceans and calling for more action to defend the body of water that cradles the world's continents.
Demand for shark fin plunging
(08/12/2014) Shark fin demand has dropped precipitously in China in just a few years, according to a new report by WildAid. Shark fin traders in Guangzhou—the current informal capital of the shark fin trade—say their sales have fallen by 82 percent in just two years, according to WildAid.
Planting meadows in the ocean: technique may help restore disappearing seagrass beds
(08/11/2014) Eelgrass is an important part of many ocean ecosystems, but is disappearing due to human impacts. However, a study published recently in found eelgrass beds could benefit from a restoration technique using seed-filled pearl nets.
Blue-footed boobies on the decline, plummeting sardine stocks may be to blame
(08/06/2014) The iconic blue-footed booby of the Galapagos Islands has suffered a population decline of 50 percent in less than 20 years, according to research conducted by biologists from Wake Forest University.
Elephants under the sea: awkward-looking fish modify the coral-reef ecosystem in mixed ways
(08/06/2014) Bumphead parrotfish are noisy feeders. They break off large branches of corals using their powerful beaks, grind them up in their bodies to extract nutrients, and expel the undigested material in large cloudy plumes of feces. Their voracious feeding is, however, not just a loud, messy affair. During the course of their feeding, they also change the coral reef ecosystem in numerous ways.
The world's best mother: meet the octopus that guards its eggs for over four years
(07/30/2014) The ultimate goal of all species on the planet is procreation, the act of making anew. But few mothers could contend with a deep-sea octopus, known as Graneledone boreopacifica, which researchers have recently observed guarding its eggs for four-and-a-half years (53 months), before likely succumbing to starvation soon after.
No longer 'deaf as a stump': researchers find turtles chirp, click, meow, cluck
(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
(09/20/2013) Armed Russian military have stormed a Greenpeace ship protesting against oil exploitation in remote Arctic waters.
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.
