April Flowers for redOrbit.com - Your Universe Online A research team from Nanjing Normal University and BGI has completed original genomic research on the Yangtze River dolphin (Lipotes vexillifer), commonly known as Baiji. The study, published in Nature Communications, provides new insight into the genetic and evolutionary adaptations of dolphins and valuable resources for the conservation of mammals, and in particular, of cetaceans. The baiji has been nicknamed "goddess of the...

Genetics of net entanglement has implications for small cetacean conservation Dolphins along coast of Argentina could experience a significant loss of genetic diversity because some of the animals that accidently die when tangled in fishing nets are related. According to a new genetic analysis published this week in the journal PLoS One, Franciscana dolphins that die as by-catch are more than a collection of random individuals: many are most likely mother-offspring pairs. This result, which...

Finless porpoises may be more endangered than previously thought. A new study of finless porpoises, a rare type of toothed whale, found that there are two species, not one, and they rarely intermingle. Scientists say that finless porpoises living in the fresh waters of China's Yangtze river are genetically unique, numbering fewer than 1000.  They warn that greater efforts must be made to prevent these animals. The whales inhabit a wide range of tropical and temperate waters...

Researchers report finding a stronghold for the Irrawaddy, one of the world's rarest freshwater dolphins, deep in the Bangladesh jungles. Scientists counted nearly 6,000 of the dolphins in the South Asian country's Sundarbans mangrove forest adjacent to the Bay of Bengal, the Wildlife Conservation Society said in a release. Before the find by the Wildlife Conservation Society there were only a few hundred of the Irrawaddy believed alive. This discovery gives us great hope that there is a...

The United Nations said recently that man-made threats such as rising populations, felling of forests, hunting, pollution and climate change are all contributing to the world's worst spate of extinctions since the dinosaurs vanished 65 million years ago. Yet scientists must undergo endless searching to prove that any individual species has gone the way of the dodo. "If there's one thing in my career I'd like to be proved wrong about, it's the baiji," said Sam Turvey of the Zoological Society...

By JEREMY LAURANCE Why are we asking this now? Yesterday, a species of freshwater dolphin found only in the Yangtze river in China was declared extinct. Called the baiji, meaning white flag in Chinese, the Yangtze river dolphin had a pale skin and distinctive long snout and had been found in the river for more than 20 million years. How can we be sure the Yangtze river dolphin is extinct? We can't - but the evidence is very strong. The last confirmed sighting was in 2002 when it was...

BEIJING -- A rare, nearly blind white dolphin that survived for millions of years is effectively extinct, an international expedition declared Wednesday after ending a fruitless six-week search of its Yangtze River habitat. The baiji would be the first large aquatic mammal driven to extinction since hunting and overfishing killed off the Caribbean monk seal in the 1950s. For the baiji, the culprit was a degraded habitat - busy ship traffic, which confounds the sonar the dolphin uses to find...

The Ganges River Dolphin (Platanista gangetica gangetica) and Indus River Dolphin (Platanista gangetica minor) are two sub-species of freshwater or river dolphins found in India and Pakistan. From the 1970s they had commonly been regarded as separate species. The Ganges River Dolphin is primarily found in River Ganges and its tributaries in India while the Indus River Dolphin is found in the Indus river in Pakistan Taxonomy Until the 1970s the Indus and Ganges River Dolphins were...
