A new mapping technology using a radar and optical imaging combination has detected a significant increase in mining since 2000, threatening the region's forests and water quality.

As the world’s only captive baiji – or Yangtze river dolphin – Qi Qi was something of a celebrity in China and his caretakers kept a close eye on his health. That care may explain why, after being injured by fishermen, he lived an impressive 22 years in the Freshwater Dolphin Research Center in Wuhan, China.

But it turns out they share a superpower - they hunt prey by emitting high-pitched sounds and listening for a returning echo. A recent study published in the journal Nature Letters has shown that the regions of the genome responsible for this ability are strikingly similar between these very different mammals.

The discovery was made after a team of researchers looked at the world's humpback dolphins (in the genus <i>Sousa</i>), 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.

Footage showed infant and adult dolphins being harpooned then stabbed and clubbed before, in some cases, being cut open and butchered while still alive. The slaughtered dolphins were cut up and used as bait. Dolphins are also killed for human consumption in Peru even though it is illegal.

There are only 55 Maui dolphins (Cephalorhynchus hectori maui) now found on the west coast of New Zealand’s North Island, less than half the 2005 population with numbers continuing to decline. Less than 20 of the remaining Maui’s are breeding females and their slow reproductive rates make it difficult to increase their numbers when faced with an even bigger danger: fishing nets.

Researchers now believe a number of factors may have killed the animals. Writing in the open-access journal PLoS ONE, scientists theorize that the dolphins died a sudden influx of freshwater from snowmelt after being stressed and weakened by an abnormally cold winter and the impacts of the BP oil spill.

New Zealand government figures show that Maui's dolphin (Cephalorhynchus hectori maui) are down to just 55 mature individuals, falling from 111 in 2005. The small cetaceans, measuring up to 1.7 meters (5.5 feet), are imperiled due to drowning in gillnets with the most recent death by a fisherman's net occurring in January.

Last December the organizations recorded 147 whale products on sale at Amazon Japan despite an international whaling moratorium since 1986. Japan, along with Iceland and Norway, continues to industrially hunt whales. Japan says their whale hunt is for scientific purposes only, but environmentalists dispute this.

Split into two subspecies, the Ganges River dolphin (Platanista gangetica gangetica) and the Irrawaddy River dolphin (Platanista gangetica minor), the new sanctuaries will benefit both. Listed as Endangered by the IUCN Red List, the south Asian freshwater dolphin has disappeared from much of its habitat. Already Asia has its other freshwater dolphin species: the baiji (Lipotes vexillifer) was declared functionally extinct into 2006 after a survey of the Yangtze River failed to find a single individual.

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.

The controversial hunt, which kills some 15,000 dolphins annually, produces cheap meat-for-consumption that on average contains over double Japan's limit on mercury contamination. "We are very concerned that people in Japan are threatening their health and possibly that of their children by unwittingly eating Dall’s porpoise meat that is dangerously contaminated with poisons such as mercury and PCBs," Andy Ottaway, Director of Campaign Whale, said in a press release.

The short answer: no. The gruesome photos that are making the media rounds over the last week of oiled birds, fish, and crustaceans are according to experts only a small symbol of the ecological catastrophe that is likely occurring both in shallow and deep waters. Due to the photos, birds, especially the brown pelican, have become the symbol of the spill to date. But while dozens of birds have been brought to rescue stations covered in oil, the vast majority will die out at sea far from human eyes and snapping cameras, according to Sharon Taylor a vet with the US Fish and Wildlife Service.

The National Marine Fisheries Service reported today finding six dead dolphins in Louisiana, Mississippi, and Alabama since May 2nd. Officials are saying the deaths could be related to the oil spill or may be due to natural deaths from calving.
