More Than Half of Penguin Species are Under Threat
More than 180 scientists and government officials have recently gathered in Boston for the 7th International Penguin Conference. The conclusions of the conference are rather alarming: the scientists warn that 10 of the 18 penguin species are experiencing population decline and that a variety of things are threatening their long-term survival, with some of these species facing extinction by the end of the 21st century.
Four main factors are threatening penguins. The first is over-fishing: Because of the rapid increase in fishing operations in the past decades, penguins are now competing with us for food, and our industrial fishing fleets are simply more effective at catching fish. "The large scale harvesting of anchovy and sardine stocks have directly reduced the prey available to many penguin species including Macaroni and Chinstrap penguins in the South Atlantic" Thousands of penguins are also killed when they are caught in fishing nets.
The second factor is climate change: Many penguin species are highly dependent on small schooling fish for food. The changing climate can affect the migratory patterns of these fish, making it harder for penguins to find food.... ...

'No extra money' for biodiversity protection
European politicians warn that there will be no additional funding for developing nations.
The European Union looks set to disappoint developing countries by turning down requests for more money to protect biodiversity outside the EU.... "They are asking for more financing. That's normal. But we have a problem, we don't have it," said Joke Schauvliege, the Flemish minister for environment, who is leading discussions with her counterparts from other member states. "We are now in a financial situation where we are not in a position to put more money on the table," she told journalists at a biodiversity conference in Ghent, Belgium.... But the Commission's environment department spies a window of opportunity, with reforms of the Common Agricultural Policy and the Common Fisheries Policy also getting under way - two policies long under fire for failing to prevent habitat loss, pesticide pollution and overfishing.
"Biodiversity is not just about protecting species. It is also about nature's ability to produce the goods and services that we need," Potocnik told delegates. "We have to go beyond lip service and truly integrate biodiversity into our policies." ...

Report: 21 percent of Africa's freshwater species threatened with extinction
More than a fifth of Africa's freshwater species are threatened with extinction, and their disappearance could threaten livelihoods across the continent, according to a new study by the International Union for Conservation of Nature (IUCN).
The study, conducted for the IUCN's Red List of Threatened Species, assessed 5,167 African freshwater species over a five-year period. Two hundred scientists contributed to the report, which covers fish, mollusks, crabs, aquatic plants and aquatic insects such as dragonflies and damselflies....
[A]n introduced species (the Nile perch, Lates niloticus) have caused a reduction in the lake's native species over the last 30 years and as a result threatened traditional fisheries that any in the region depend upon for their livelihoods and food supplies. According to the study, 45 percent of the 191 fish species in Lake Victoria are threatened or even thought to already be extinct. Lake Victoria is located between Kenya, Uganda and Tanzania.
Sometimes overfishing is the problem, thanks to Africa's growing population. In Lake Malawi (located between Malawi, Mozambique and Tanzania), the population of one important fish species, Oreochromis karongae, has declined 70 percent in just the past 10 years. The IUCN has listed the species as endangered since 2004. ...

20 years left: mammals plunge into extinction in northern Australia
At dusk, the dry savannah of the Kimberley was once alive with the scuttling and foraging of the burrowing bettong, a marsupial whose ''countless numbers'' were marvelled at by early surveyors.
Along with many species of quolls, bandicoots, possums and marsupial rats, the bettongs had thrived for millions of years in northern Australia, surviving ice ages, surging sea levels and human hunters.
But many of these natives are unlikely to survive another decade or two, according to a new report which reveals an abrupt, stunning plunge towards mass extinction in the past few years. At the 136 sites across northern Australia that have been repeatedly surveyed since 2001, the mammal populations have dropped by an average of 75 per cent. The number of sites classified as ''empty'' of mammal activity rose from 13 per cent in 1996 to 55 per cent in 2009.
''Twenty years ago we would go out and it would be a bonanza of native animals,'' a Charles Darwin University researcher, John Woinarski, said. ''Now we hardly catch anything - it's silent.'' ...
