(05/15/2012) In 48 years wildlife populations in the tropics, the region that holds the bulk of the world's biodiversity, have fallen by an alarming 61 percent, according to the most recent update to the Living Planet Index. Produced by the World Wide Fund for Nature (WWF) and the Zoological Society of London (ZSL), the index currently tracks almost 10,000 populations of 2,688 vertebrate species (including mammals, birds, reptiles, amphibians, and fish) in both the tropics and temperate regions.
Educating the next generation of conservation leaders in Colombia
(05/14/2012) Colombia's northern departments of Cordoba and Bolivar are home to an abundance of coral reefs, estuaries, mangroves forests, and forests. Rich in both marine and terrestrial wildlife, local communities depend on the sea and land for survival, yet these ecosystems are imperiled by booming populations, overexploitation, and unsustainable management. Since 2007, an innovative education program in the region, the Guardians of Nature, has worked to teach local children about the ecology of the region, hoping to instill a conservation ethic that will aid both the present and the future.
Manta rays tracked by satellite
(05/11/2012) Satellite tracking technology has revealed new insights into the behavior of manta rays, reports the Wildlife Conservation Society (WCS). The findings are published in this week's issue of the journal PLoS.
Featured video: the oceans and Rio+20
(05/10/2012) A new video by Pew Environment Group and the Zoological Society of London (ZSL) hopes to convince policy-makers attending the Rio+20 Summit on Sustainable Development this summer that urgent action is needed to save the ocean's from an environmental crisis.
Over 30 Yangtze porpoises found dead in China as population nears extinction
(05/01/2012) Six years after the Yangtze river dolphin (Lipotes vexillifer), or baiji, was declared "functionally extinct" by scientists, another marine mammal appears on the edge of extinction in China's hugely degraded Yangtze River. In less than two months, 32 Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis), a subspecies of the finless porpoise, have been dead found in Dongting and Poyang Lakes in the Yangtze, reports the World Wide Fund for Nature (WWF).
Carnage in Komodo: world-famous reef destroyed by poachers' bombs
(04/25/2012) Illegal fishermen have been utilizing homemade bombs to kill fish off the coast of Komodo Island, Indonesia, reports the Associated Press (AP); the bombs have not only injured fish populations in the protected area, but has also blasted biodiverse coral reefs popular with tourists. A scuba teacher told the AP that a section of Tatawa Besar coral reef, a popular diving spot, had been "blasted, ripped off, turned upside down."
BP Deepwater Horizon deformities: eyeless shrimp, clawless crabs
(04/24/2012) Two years after the BP-leased Deepwater Horizon drilling rig exploded in the Gulf of Mexico, killing eleven and causing an oil spill that lasted three months, scientists say the impacts on the Gulf ecosystem are only beginning to come to light and the discoveries aren't pretty.
Will mega-dams destroy the Amazon?
(04/18/2012) More than 150 new dams planned across the Amazon basin could significantly disrupt the ecological connectivity of the Amazon River to the Andes with substantial impacts for fish populations, nutrient cycling, and the health of Earth's largest rainforest, warns a comprehensive study published in the journal PLoS ONE. Scouring public data and submitting information requests to governments, researchers Matt Finer of Save America’s Forests and Clinton Jenkins of North Carolina State University documented plans for new dams in Bolivia, Brazil, Colombia, Ecuador, and Peru.
Featured video: Google Earth highlights imperiled coral reefs around the world
(04/18/2012) A new video by Google Earth and the World Resources Institute (WRI) highlights the world's many endangered coral reefs. A part of the WRI's Reefs at Risk program, the video highlights regional and global threats to the oceans' most biodiverse ecosystem. According to the WRI, a stunning 75 percent of the world's reefs are currently threatened.
Whole Foods bans 'red' fish from its stores
(04/10/2012) Whole Foods has announced it will be the first grocery chain in the U.S. to no longer sell any seafood in the "red." Based on sustainability ratings by the Monterey Bay Aquarium and Blue Ocean Institute, fish labeled red are those that are considered either overfished or fished in a manner that impacts other species or damages marine ecosystems. Beginning Earth Day, April 22nd, Whole Foods will no longer be selling Atlantic halibut, grey sole, skate, octopus, tautog, sturgeon, among others. Already, the store doesn't sell some unsustainable catches such as bluefin tuna and orange roughy.
Beyond Bigfoot: the science of cryptozoology
(03/26/2012) Anyone who doubts cryptozoology, which in Greek means the "study of hidden animals," should remember the many lessons of the past 110 years: the mountain gorilla (discovered in 1902), the colossal squid (discovered in 1925, but a full specimen not caught until 1981), and the saola (discovered in 1992) to name a few. Every year, almost 20,000 new species are described by the world's scientists, and a new book by Dr. Karl Shuker, The Encycloapedia of New and Rediscovered Animals, highlights some of the most incredible and notable new animals uncovered during the past century.
Animal picture of the day: a sun-colored weedy scorpion fish
(03/26/2012) This bright yellow weedy scorpion fish (Rhinopias frondosa) is the newest member of the Wildlife Conservation Society's (WCS) New York Aquarium. Weedy scorpion fish are found in the Indo-Pacific Ocean and in a wide variety of colors.
Three U.S. retailers pledge to avoid fish from embattled Ross Sea
(03/14/2012) The Ross Sea, a massive bay off Antarctica, has been dubbed the world's last ocean due to its pristine state, long-untouched by industry and fisheries. However, over the last 15 years New Zealand commercial fisheries have entered the sea, seeking the slow-growing Antarctic toothfish which is usually sold as the high-end Chilean sea bass. Now as conservation groups plead for nations to grant the Ross Sea protected status, Greenpeace has begun a campaign to get good retailers to steer clear of stocking Antarctic toothfish. To date, Safeway, Wegmans, and Harris Teeter has all pledged not to source from the Ross Sea.
Alaskan fishermen tell government to focus on salmon, not logging
(03/12/2012) Alaskan fishermen and tour operators visited Washington D.C. last week to urge the federal government to shift the focus from logging to conservation in the Tongass rainforest. Local Alaskans along with NGOs Trout Unlimited, Alaska Program, and Sitka Conservation Society, made the case that conservation, including the restoration of fish habitat, was a far better strategy for the local economy and jobs than logging. The Tongass rainforest is currently the subject of a controversial logging proposal by the government for the indigenous-owned company, Sealaska.
Cute baby animal photos of the day: baby pot-bellied seahorses
(03/05/2012) The Wildlife Conservation Society's (WCS) New York Aquarium has recently celebrated the arrival of "fry" (baby) pot-bellied seahorses (Hippocampus abdominalis). Found in the seas surrounding Australia, the pot-bellied seahorse is protected under CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora), since they are stolen from the wild for traditional medicine, decorations, and pets.
Sawfish impale, cleave prey with snout
(03/05/2012) Although all seven species of sawfish are nearly extinct, scientists have spent little time studying these vanishing species. However that is changing as a new study in Current Biology sheds light on the sawfishes' most distinguishing feature: its long toothed snout, which gives the fish its name. "I was surprised to see how skilled sawfish are with their saw," said co-author Barbara Wueringer of the University of Queensland in a press release. "They use their saw to impale prey on the rostral teeth by producing several lateral swipes per second."
Paleontologists reconstruct extinct, "elegant" penguin
(02/27/2012) Around 25 million years ago a penguin with a long, sharp beak and massive flippers lived in a New Zealand that was almost entirely underwater. The bird, named Kairuku after a Maori word that means "diver who returns with food," was first discovered in 1977, but has only recently been reconstructed by scientists in a study in the Journal of Vertebrate Paleontology.
Scientists recommend marine protected areas for Madagascar
(02/27/2012) With the government of Madagascar planning to increase marine protected areas by one million hectares, a group of researchers have laid out flexible recommendations in a new study in the open access journal PLoS ONE. The researchers employed four different analyses in order to highlight a number of different conservation options, however the different analyses pointed to the need to protect certain areas with high biodiversity, including the Barren Islands' reefs, the reefs of Juan de Nova, the Banc de Leven, and the shallow banks of the Cap Sainte Marie.
Atlantic sturgeon gains protection under the Endangered Species Act
(02/01/2012) The U.S. federal government has listed the massive and bizarre Atlantic sturgeon (Acipenser oxyrinchus) under the protection of the Endangered Species Act (ESA). Historically overfishing decimated the Atlantic sturgeon, while on-going threats include pollution and infrastructure, like dams and bridges that destroy habitat. Fishing for the Atlantic sturgeon has been banned since 1998, they are still caught as bycatch.
Photos: 46 new species found in little-explored Amazonian nation
(01/25/2012) South America's tiniest independent nation still hides a number of big surprises: a three week survey to the sourthern rainforests of Suriname found 46 potentially new species and recorded nearly 1,300 species in all. Undertaken by Conservation International's (CI) Rapid Assessment Program (RAP) the survey found new species of freshwater fish, insects, and a new frog dubbed the "cowboy frog" for the spur on its heel. While Suriname may be small, much of its forest, in the Guyana Shield region of the Amazon, remains intact and pristine. The Food and Agriculture Organization (FAO) estimates that 91 percent of Suriname is covered in primary forests, however this data has not been updated in over two decades.
Featured video: tuna industry bycatch includes sea turtles, dolphins, whales
(01/16/2012) A Greenpeace video, using footage from a whistleblower, shows disturbing images of the tuna industry operating in the unregulated waters of the Pacific Ocean. Using fish aggregation devices (FADs) and purse seine nets, the industry is not only able to catch entire schools of tuna, including juvenile, but also whatever else is in the area of the net.
Bycatch-reducing fish trap wins $20,000
(01/11/2012) An innovative fish trap that allows small non-target fish to escape won a new content by RARE Conservation and National Geographic to fund solutions to overfishing. Developed through studies in Curaçao and Kenya with the Wildlife Conservation Society, the trap has gaps for juvenile fish to swim out of reportedly reducing bycatch by 80 percent. The entry won a $20,000 grant.
World's most expensive tuna
(01/05/2012) A 593 pound Pacific bluefin tuna sold for $735,000 (56.49 million yen) in Tokyo's Tsukiji market today. This beats the previous record price hit last year by over $260,000. Why so expensive? Bluefin tuna, considered the best sashimi and sushi in the world, have been fished to near extinction with the population of the Pacific bluefin the most stable to date.
Top 10 Environmental Stories of 2011
(12/22/2011) Many of 2011's most dramatic stories on environmental issues came from people taking to the streets. With governments and corporations slow to tackle massive environmental problems, people have begun to assert themselves. Victories were seen on four continents: in Bolivia a draconian response to protestors embarrassed the government, causing them to drop plans to build a road through Tipnis, an indigenous Amazonian reserve; in Myanmar, a nation not known for bowing to public demands, large protests pushed the government to cancel a massive Chinese hydroelectric project; in Borneo a three-year struggle to stop the construction of a coal plant on the coast of the Coral Triangle ended in victory for activists; in Britain plans to privatize forests created such a public outcry that the government not only pulled back but also apologized; and in the U.S. civil disobedience and massive marches pressured the Obama Administration to delay a decision on the controversial Keystone XL pipeline, which would bring tar sands from Canada to a global market.
Photos: 208 species discovered in endangered Mekong region in 2010
(12/14/2011) Last year researchers scoured forests, rivers, wetlands, and islands in the vanishing ecosystems of the Mekong Delta to uncover an astounding 208 new species over a twelve month period. A new report by the World Wide Fund for Nature (WWF) highlights a number of the new species—from a new snub-nosed monkey to five new meat-eating pitcher plants to a an all-female, cloning lizard—while warning that many of them may soon be gone as the Mekong Delta suffers widespread deforestation, over-hunting and poaching, massive development projects, the destruction of mangroves, pollution, climate change, and a growing population.
Seahorses under stress
(11/21/2011) With about 25 million seahorses sold each year, global consumption of seahorses is massive. They’re used in traditional Asian medicine and also sold as curios and aquarium pets. Over the last decade, overexploitation and habitat degradation have prompted declines of between 15 to 70 percent in many seahorse populations. Marine biologist and author Helen Scales notes there is much still unknown about seahorses.
US reduces catch limit of 'most important fish in the sea'
(11/15/2011) The Atlantic State Marine Fisheries Commission (ASMFC) has slashed the allowable catch of a tiny fish named menhaden by 37 percent by 2013. Dubbed the 'most important fish in the sea' by author H. Bruce Franklin, the menhaden plays a critical role in marine ecosystems as a food source for larger fish, seabirds, and marine mammals, as well as helping to regulate the marine environment. However, due to overfishing the menhaden fish has dropped 92 percent from its historical population.
Covert Creatures: The Clandestine Lives of Seahorses
(11/15/2011) Seahorses are strange looking creatures, with a horse's head on top of a kangaroo’s pouched belly, bulging, swiveling chameleon eyes, a prehensile monkey tail, color-changing armor and a royal crown, all shrunk down to the size of a chess piece. To marine biologist Helen Scales, these elusive creatures are a perfect symbol of the ocean's biodiversity.
Tracking the coelacanth: Two decades of research confirms a viable population in Comoros
(11/14/2011) It took a custom-made submarine, billionaire Paul Allen, and a tenacious desire lasting well beyond two decades to unveil enigmatic details about the life of the coelacanth—the primitive fish that invariably hooks researchers. A study published earlier this year in the journal Marine Biology summarizes 21 years of coelacanth population research by one team, led by Hans Fricke of the Max Planck Institute for Marine Microbiology in Bremen, Germany. Working in the Indian Ocean off the African island nation of Comoros, Fricke documented a stable population of Latimeria chalumnae. However, his study notes that deep-set fishing nets could threaten these unique animals.
First global assessment finds highest-grossing tunas and billfishes most vulnerable to extinction
(11/09/2011) Sleek, powerful tunas and billfishes that ply the open ocean garner some of the highest prices of any fish. In January, a single bluefin tuna fetched a record $396,000 at a Tokyo auction. Yet wild fish populations pay a still higher price for such exorbitant demand: the threat of extinction. The first assessment of an entire group of commercially valuable marine species found that the most threatened fish are generally the ones reeling in the most money, including bluefin tuna and bigeye tuna.
Researchers challenge idea that marine reserves promote coral recovery
(11/09/2011) Fleshy whorls of thick brown algae blanket the once-vibrant corals in Glover’s Reef, Belize. According to a controversial study published August 14 in the journal Coral Reefs, a decade of marine reserve protection has failed to help these damaged Caribbean corals recover.
Picture of the day: Mekong sunrise
(11/02/2011) The Mekong River, the world's 10th largest, flows through six countries in East Asia: China, Thailand, Laos, Myanmar, Cambodia, and Vietnam.
Small marine fish need protection too
(10/25/2011) It has long been known that overfishing has decimated some populations of tuna, shark, cod, as well as other big predatory fish; however two recent studies have pointed out that overfishing is also threatening small fish such as anchovies, sardines, mackerel, herring, menhaden, and krill. Although tiny, these species are vital to marine ecosystems since many species higher up on the food chain—from seabirds to marine mammals to big fish—wholly depend on them for survival.
Fishing industry exceeds Atlantic bluefin quota by 141 percent
(10/18/2011) In 2010 the fishing industry exceeded its quota of eastern Atlantic bluefin tuna (Thunnus thynnus) by 141 percent, according to a new analysis by Pew Environment Group. The analysis depends on official data, thereby leaving out the massive black market on Atlantic bluefin tuna.
Poor in Madagascar see fish plundered for foreign consumption
(10/11/2011) A new study warns that overfishing could exacerbate poverty and political stability in one of the world's poorest nations: Madagascar. According to the recent study by the University of British Columbia's Sea Around Us Project and Malagasy NGO Blue Ventures, fish catches in the African island-nation from 1950 to 2008 are actually double the official numbers, with foreign wealthy nations currently taking half the haul.
California governor signs ban on shark fin trade
(10/10/2011) California governor Jerry Brown on Friday signed legislation banning the the importation, possession and sale of shark fins in California.
Deepwater oil spill likely to hurt fish populations over decades
(09/28/2011) Oil pollution doesn't have to kill fish to have a long-term impact, according to a recent study in the Proceedings of the National Academy of Sciences (PNAS). Researchers found that Gulf killifish (Fundulus grandis) that had been exposed to very low to non-detectable levels of oil contamination from the Deepwater oil spill last year, still showed developmental problems that are likely to impact fish populations for decades to come.
Sowing the seeds to save the Patagonian Sea
(09/07/2011) With wild waters and shores, the Patagonia Sea is home to a great menagerie of marine animals: from penguins to elephants seals, albatrosses to squid, and sea lions to southern right whales. The sea lies at crossroads between more northern latitudes and the cold bitter water of the Southern Ocean, which surround Antarctica. However the region is also a heavy fishing ground, putting pressure on a number of species and imperiling the very ecosystem that supplies the industry. Conservation efforts, spearheaded by marine conservationist Claudio Campagna and colleagues with the Wildlife Conservation Society (WCS), are in the early stages. Campagna, who often writes about the importance of language in the fight for preservation, has pushed to rename the area to focus on its stunning wildlife.
New species is eel-equivalent of the coelacanth
(08/18/2011) The ocean holds endless surprises still. In an underwater cave off the Pacific island nation of Palau, reachers have made an astounding discovery: an eel species unknown to science that harkens back 200 million years. The species, described in the Proceedings of the Royal Society B as an 'enigmatic, small eel-like fish', sports anatomical features that differentiate it from the over 800 known species of eel surviving today.
Animal picture of the day: the jaws of the piranha
(08/10/2011) Few fish have a more fearsome reputation than the piranha. Yet recent research has shown that attacks on humans are rare and often accidental, though they do eat their prey alive and are capable of stripping a cattle carcass bare (though it doesn't happen instantaneously).
Fish use tools
(07/17/2011) A blackspot tuskfish (Choerodon schoenleinii) has been photographed picking up a clam in its mouth, swimming over to a rock, and then using the rock as an anvil by smashing the clam against it until it breaks open. In the journal Coral Reefs scientists argue this is the first conclusive evidence of a fish using tools. Once thought only the domain of humans, biologists have found that tool use is actually present all over the animal kingdom, from elephants to chimps, and crows to capuchins. Such tool use is often considered evidence of higher intelligence.
Decline in top predators and megafauna 'humankind’s most pervasive influence on nature'
(07/14/2011) Worldwide wolf populations have dropped around 99 percent from historic populations. Lion populations have fallen from 450,000 to 20,000 in 50 years. Three subspecies of tiger went extinct in the 20th Century. Overfishing and finning has cut some shark populations down by 90 percent in just a few decades. Though humpback whales have rebounded since whaling was banned, they are still far from historic numbers. While some humans have mourned such statistics as an aesthetic loss, scientists now say these declines have a far greater impact on humans than just the vanishing of iconic animals. The almost wholesale destruction of top predators—such as sharks, wolves, and big cats—has drastically altered the world's ecosystems, according to a new review study in Science. Although researchers have long known that the decline of animals at the top of food chain, including big herbivores and omnivores, affects ecosystems through what is known as 'trophic cascade', studies over the past few decades are only beginning to reveal the extent to which these animals maintain healthy environments, preserve biodiversity, and improve nature's productivity.
Forgotten species: the rebellious spotted handfish
(07/12/2011) Evolution is a bizarre mistress. In her adaptation workshop she has crafted parrots that don't fly, amphibians with lifelong gills, poison-injecting rodents, and tusked whales. In an evolutionary hodge-podge that is reminiscent of such mythical beasts as chimeras and griffins, she has from time-to-time given some species' attributes of others, such as the marine iguana who is as happy underwater as a seal, the duck-billed platypus that lays eggs like a reptile, and the purple frog that has a lifestyle reminiscent of a mole. Then there's one of her least-known hodge-podges: the fish who 'walks' with hands instead of swimming.
Honduras protects sharks in all its waters
(06/26/2011) Endangered sharks are finding more sanctuaries. Honduras has announced that commercial shark fishing will be banned from its 92,665 square miles (240,000 square kilometers) of national waters. Honduras says the ban, which follows a moratorium on shark fishing, will bring in tourism revenue and preserve the marine environment.
Ocean prognosis: mass extinction
(06/20/2011) Multiple and converging human impacts on the world's oceans are putting marine species at risk of a mass extinction not seen for millions of years, according to a panel of oceanic experts. The bleak assessment finds that the world's oceans are in a significantly worse state than has been widely recognized, although past reports of this nature have hardly been uplifting. The panel, organized by the International Program on the State of the Ocean (IPSO), found that overfishing, pollution, and climate change are synergistically pummeling oceanic ecosystems in ways not seen during human history. Still, the scientists believe that there is time to turn things around if society recognizes the need to change.
Efficient aquaculture needed for food security, particularly in Asia
(06/17/2011) Aquaculture is the best way to meet future demand for seafood, which is expected to rise significantly by 2030 due expanding middle class populations in China, India, and Southeast Asia expand, argues a new report.
Last chance to see: the Amazon's Xingu River
(06/15/2011) Not far from where the great Amazon River drains into the Atlantic, it splits off into a wide tributary, at first a fat vertical lake that, when viewed from satellite, eventually slims down to a wild scrawl through the dark green of the Amazon. In all, this tributary races almost completely southward through the Brazilian Amazon for 1,230 miles (1,979 kilometers)—nearly as long as the Colorado River—until it peters out in the savannah of Mato Grosso. Called home by diverse indigenous tribes and unique species, this is the Xingu River.
Google Earth used to identify marine animal behavior
(06/14/2011) From the all-seeing eye of Google Earth, one can spy the tip of Mount Everest, traffic on 5th Avenue in Manhattan, and the ruins of Machu Picchu, but who would have guessed everyone's favorite interactive globe would also provide marine biologists a God's-eye view of fish behavior? Well, a new study in the just-launched Scientific Reports has discovered visible evidence on Google Earth of the interactions between marine predators and prey in the Great Barrier Reef.
Ocean acidification dissolves algae, deafens fish
(06/02/2011) As if being a major contributor to global warming wasn't enough, the increasing amount of carbon dioxide produced through human activity is also acidifying our oceans - and doing so more rapidly than at any other time in more than half a million years. New projections show that at current rates of acidification, clownfish and many species of algae may be unable to survive by 2100.
Photos: the top ten new species discovered in 2010
(05/23/2011) If we had to characterize our understanding of life on Earth as either ignorant or knowledgeable, the former would be most correct. In 250 years of rigorous taxonomic work researchers have cataloged nearly two million species, however scientists estimate the total number of species on Earth is at least five million and perhaps up to a hundred million. This means every year thousands of new species are discovered by researchers, and from these thousands, the International Institute for Species Exploration at Arizona State University selects ten especially notable new species.
