The Yangtze River may have lost another inhabitant: the Chinese paddlefish

(10/22/2009) In December of 2006 it was announced that the Yangtze River dolphin, commonly known as the baiji, had succumbed to extinction. The dolphin had survived on earth for 20 million years, but the species couldn't survive the combined onslaught of pollution, habitat loss, boat traffic, entanglement in fishing hooks, death from illegal electric fishing, and the construction of several massive dams. Now, another flagship species of the Yangtze River appears to have vanished.


No killing yet as season begins for dolphin slaughter made famous by The Cove

(09/02/2009) Due to the new documentary The Cove, the town of Taiji, Japan is suddenly famous, or perhaps more aptly, infamous. Winner of the documentary award at the Sundance Film Festival, the film uncovers a cove in Taiji where over two thousand dolphins are slaughtered every year due to the billion dollar dolphin entertainment industry. Their dolphin's meat is then labeled as fish and given to children for school lunches, even though as top level predators the meat is heavily tainted with mercury.


Study refutes criticism of polar bear listing under the Endangered Species Act

(05/20/2009) In May 2008 the Bush Administration listed the polar bear under the Endangered Species Act (ESA). The listing immediately received allegations of being politically biased and not based on sound science. However, a new paper addresses the allegations point by point and concludes that the decision to add the polar bear under the ESA was not only scientifically sound, but right.


Blue whales return to migration pattern used before commercial whaling

(05/13/2009) The blue whale may be returning to a migration route that it abandoned during commercial whaling. Researchers have discovered whales migrating from California to the coastlines of British Columbia and the Gulf of Alaska for the first time since 1965. Fifteen different cases of whales have been recorded in the north Pacific; four of the whales were individuals who had been viewed off the coast of California, as well.


New Australian dolphin spits at food

(04/13/2009) Only recognized as a new species in 2005, the snubfin dolphin has been observed spitting jet streams of water at schools of fish. Spitting at the fish helps the dolphins round them up into groups where they are easier to catch.


Study confirms that sonar can cause deafness in dolphins

(04/08/2009) A new study in Biology Lettersconfirms what marine biologists have long suspected: loud sonar can cause temporary deafness in dolphins, possibly explaining some mass strandings. The study, using a captive dolphin in a controlled experiment, found that sonar at high prolonged levels could even lead to slight behavioral changes.


Marine Protected Areas too small for whales and dolphins

(04/07/2009) Current Marine Protected Areas (MPAs) are too small to adequately serve whales and dolphins according to the Whale and Dolphin Conservation Society (WDCS). The international organization is calling for a global network of MPAs to save the ocean's most beloved inhabitants. "A worldwide effort must be made urgently to identify and define whale and dolphin critical habitats and hot spots,” said WDCS Research Fellow, Erich Hoyt.


Massive population of rare Irrawaddy dolphins discovered in Bangladesh

(03/31/2009) The Wildlife Conservation Society (WCS) has discovered an unknown population of the rare Irrawaddy dolphin in Bangladesh numbering 6,000 individuals. The dolphins were found in the freshwater areas of the Sundarbans mangrove forest. Prior to this discovery, the largest known populations of Irrawaddy dolphins numbered only in the hundreds.


Harbor seals return to New York

(03/26/2009) More than a hundred years passed, and the Hudson River and Atlantic Ocean estuary was cleaned up—enough to support the comeback of the harbor seal. In spring of 2006, kayakers and recreational boaters who frequent the waters around the Verrazano Bridge, took note of what appeared to be marine mammals that had not been there before. Were there harbor seals, again in this urban estuary? The boaters notified the Kingsborough Community College for Maritime Studies and the New York Aquarium, who teamed up to investigate, and thus, began the first annual harbor seal survey.


Infant blue whale filmed underwater

(03/06/2009) Off the waters of Costa Rica in January 2008 scientists and photographers with National Geographic filmed an infant blue whale swimming near its mother. They believe this is the first time a baby blue whale has been filmed underwater.


Iceland reaffirms whaling targets for 2009

(02/19/2009) Iceland's interim government will allow whaling to continue through 2009 but left in question whether it would be permitted in the future, reports Reuters.


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

(02/12/2009) Fishermen calling for a resumption of whaling to restore commercial fish stocks are taking the wrong approach, argue researchers writing in the journal Science. Analyzing data on fish catch and whale abundance off the coast of northwestern Africa and the Caribbean, Leah R. Gerber and colleagues show that fishermen remove far more fish than whales consume, undermining the agreement by whaling nations that whales are driving depletion of fisheries.


Iceland raises whale killing quota to 150 fin whales, 100 minkes per year

(01/28/2009) The outgoing administration in Iceland has substantially raised the country's whaling quota, reports the BBC.


Neither slow nor stupid, manatees are killed by boats because they can't hear them

(12/12/2008) Last year 73 manatees were killed by boats in Florida, despite two decades of manatee-related protections. In fact, manatee deaths due to boat collisions have only increased since protections were implanted. A recent study at the Florida Atlantic University has finally revealed why boats are so dangerous to manatees: the manatee cannot run from what it does not hear.


Manatees become conservation symbol for communities in Mexico

(12/01/2008) Local conservation efforts are helping protect endangered manatees in Chiapas, Mexico, report researchers writing in the December issue of Tropical Conservation Science.


A new reason to ban whaling: your health

(11/28/2008) Health officials have recommended a ban on the eating of pilot whales, a traditional food source, in the Faroe Islands, reports New Scientist. The build-up of toxins — which bioaccumulate up the food chain as predators feed on tainted organisms — have rendered whale meat harmful to humans.


Caspian seal numbers plummet 90%

(11/12/2008) Caspian Seal populations have declined 90% in the past 100 years, prompting the IUCN to switch their designation from Vulnerable to Endangered.


Supreme Court lifts ban on sonar testing, whales lose

(11/12/2008) A Supreme Court decision will allow the Navy to continue its of sonar in training exercises off the coast of California, a defeat for environmental groups who say sonar is harmful to whales, reports the Associated Press.


U.S., Mexico, Canada pledge to save the vaquita from extinction

(10/30/2008) The United States, Mexico, and Canada will work together to conserve the vaquita, the world's smallest, and most endangered, species of cetacean.


Argentina bans fishing, trawling in eco-rich area

(10/09/2008) The government of Argentina has banned commercial fishing along Burdwood Bank, an 1,800 square kilometer (694 square mile) submerged island off its southern coast, according to the Wildlife Conservation Society (WCS).


Whaling Commission issues media blackout on discussions to lift whale killing ban

(09/11/2008) The survival of whales is perhaps the most successful conservation story of the 20th century. Since a moratorium on commercial hunting, some whale species have staged dramatic recoveries. In May it was announced that the humpback whale population has climbed from 1,500 to 20,000 individuals, resulting in it being "downlisted" from vulnerable to least concern, according to the IUCN's Red List. Others, like the blue whale, appear to have stable populations but recovery remains slow.


Whale meat is back on the menu in Iceland

(09/02/2008) Whale meat is back at restaurants and food markets in Iceland, reports the WALL STREET JOURNAL.


The extinction of the baiji a 'wake-up call' to conserve vaquita and other cetaceans

(08/25/2008) In December of 2006 an expedition spent six weeks surveying the Yangtze River in China for one of the world's rarest cetaceans, the baiji. Also known as 'The Goddess of the Yangtze' the shy river-dolphin had roamed the river for millions of years locating fish with echolocation. The survey came back empty-handed without a spotting a single dolphin. Dr. Jay Barlow, a member of the surveying team, described his emotions on the expedition's findings in an interview with Mongabay.com: "I was stunned. I knew the species was in trouble, but I did not think they were already gone. We really had not seen the extinction of a large mammal species in 50 years, so we grew complacent."


The long-ignored ocean emergency and what can be done to address it

(08/18/2008) This year has been full of bad news regarding marine ecosystems: one-third of coral species threatened with extinction, dead-zones spread to 415 sites, half of U.S. reefs in fair or bad condition, increase in ocean acidification, tuna and shark populations collapsing, and only four percent of ocean considered pristine. Jeremy Jackson, director of the Scripps Center for Marine Biodiversity and Conservation at the University of California, San Diego, synthesizes such reports and others into a new paper, published in the journal Proceedings of the Naional Academy of Sciences, that boldly lays out the scope of the oceanic emergency and what urgently needs to be done.


Seals used for climate change research

(08/11/2008) Animals have aided humanity for millennia. We are used to considering animals like dogs, horses, cows, and lamas as utilitarian in a very direct way, but what about elephant seals?


Rock star or marine biologist? Hans Walters chose both

(07/31/2008) There aren't many who swim with sharks by day and rock out on a stage at night, but Hans Walters does just that! A man with two distinctly different passions, music and marine biology, Walters is a supervisor for the animals at the New York Aquarium, and then after hours, grabs a microphone as lead singer (playing just enough guitar to be dangerous) for the New York-based hard rock band, 61/49.


Whale biomimicry inspires better wind turbines

(07/07/2008) By studying and mimicking the characteristics of the flippers, fins and tails of whales and dolphins, engineers have devised more a efficient way to generate wind power, reports a researcher presenting at the Society for Experimental Biology's Annual Meeting in Marseille, France.


Meet Spook, the world's oldest gray seal

(07/02/2008) At the age of 43, Spook is the oldest gray seal on record at any aquarium or zoo in the world. He has surpassed his gray seal relatives in the wild that can live to 30 years of age. Spook may be a senior citizen among seals, but retirement is not on his radar.


Caribbean Monk Seal is officially declared extinct

(06/10/2008) The NOAA fish service has officially declared the Caribbean Monk Seal extinct. The seal--the first to go extinct by human causes--has not had a confirmed sighting for fifty-six year. Many scientists believe sightings that have followed the last confirmation were probably of Hooded Seals and not the Caribbean Monk.


Fatal San Diego Shark Attack a Rare Event

(04/25/2008) Friday morning a 66-year-old swimmer was attacked and killed by a shark off Solana Beach in San Diego county. It was the first fatal shark attack in San Diego since 1994.


The Arctic's most threatened marine mammals due to climate change

(04/25/2008) A recent study has measured the sensitivity to Arctic marine mammals to climate change. The study found that the three species most vulnerable to climate change are the hooded seal, the polar bear, and the narwhal: the common thread between these species being the loss of sea ice.


New 'red list' seeks to stave off global seafood collapse

(03/03/2008) Over-fishing and destructive fishing practices have had a considerable effect on oceanic ecosystems. In 2006 a highly-reported study found that without drastic measures all wild seafood will disappear from the oceans in 50 years. Greenpeace, working against such a crash, has started a campaign that highlights 'red fish'. The twenty-two 'red' species are seafood that consumers and suppliers (including supermarkets) should avoid due to their plummeting populations and/or the damage caused by harvesting them.


Japan cancels plan to kill 50 humpback whales

(12/21/2007) Japan has canceled highly controversial plans to kill 50 humpback whales for purported "scietific purposes" (the meat is sold in fish markets) after widespread condemnation from environmentalists and governments. .


Evolution of whales challenged

(12/19/2007) Modern whales appear to have evolved from a raccoon-sized creature with the body of a small deer, according to scientists writing in the journal Nature. The results challenge the theory that cetaceans are descended from even-toed ungulates (artiodactyls) like hippos, as previous molecular analysis has suggested.


Vulnerable Australian sea lions further threatened by gillnets and lobster pots

(11/26/2007) The Australian Sea Lion inhabits only the coastal waters off south and west Australia. Historically, they were hunted almost to extinction by Europeans of the 18th and 19th centuries for their fur and oil. Beginning in 1895, certain populations of the marine mammal were placed under protection until the species gained national protection in 1975. These protections have yet to achieve their goal; Australian Sea Lion populations remain low with some subpopulations in decline. Due to these facts, Australia recently changed their conservation status to 'threatened'.


Whale stranded 1,000 miles up the Amazon river

(11/17/2007) An 18-foot minke whale was found beached on a sandbar 1,000 miles up a tributary of the Amazon river, reported Globo television and the Associated Press.


Apology for Whale Shooting given by Tribe

(09/13/2007) The ninth of September saw a gray whale shot and killed by members of the Makah Tribe, off the coast of the Washington Coast, in the Strait of Juan de Fuca.


Gray whale populations a fraction of historic level

(09/10/2007) The current population of gray whales is one-third to one-fifth of the number found in the Pacific before industrial whaling began in the 19th century, reports a new study based on genetic analysis.


Squid chasing drove evolution of whale sonar

(09/06/2007) A University of California at Berkeley study argues that dolphins and other toothed whales developed sonar to chase schools of squid swimming near the ocean surface at night.


Rare Chinese river dolphin sighting in doubt

(09/01/2007) A prominent researcher is skeptical of last week's reported sighting of the baiji, the Chinese river dolphin declared extinct earlier this year, according to the New York Times. The sighting near Tongling city in Anhui Province -- widely reported in Chinese and Western media -- was captured on video.


"Extinct" baiji river dolphin spotted alive in China

(08/29/2007) An "extinct" baiji has been spotted alive in the Yangtze River, reports Chinese state media.


Iceland halts whaling

(08/24/2007) With stagnant demand for whale meat nearly a year after ending its ban on commercial whaling, Iceland said it would not issue new whale-hunting quotas until it gets an export license from Japan, reports Reuters.


U.S. court blocks sonar testing to protect whales

(08/07/2007) A U.S. federal court blocked the Navy from using a type of sonar that environmentalists say pose a threat to whales off the coast of California. The judge noted that the Navy's own analyses concluded that the Southern California exercises "will cause widespread harm to nearly thirty species of marine mammals, including five species of endangered whales, and may cause permanent injury and death" and characterized the Navy's proposed mitigation measures as "woefully inadequate and ineffectual."


New device allows biologists to track seals under sea ice

(08/06/2007) Biologists have devised a new device for tracking how environmental change affects the physiology, behvaior, and populations of Southern elephant seals, according to a paper published in the early online edition of the journal Proceedings of the National Academy of Sciences.
