Over 100 Species Of Bats Found Within Several Acres Of Rainforest In Ecuador

Bats are a remarkable evolutionary success story representing the second largest group of mammals, outnumbered only by rodents in number of species. Now, researchers of the Leibniz-Institute for Zoo and Wildlife Research in Berlin (Germany) and Boston University (U.S.A.) have discovered the place that harbours the highest number of bat species ever recorded. In a few ha* of rainforest in the Amazon basin of eastern Ecuador, the authors have found more than 100 species of bats.

Dr. Katja Rex and colleagues captured bats at several biodiversity hotspots in the New World tropics, in the lowland rainforest of Costa Rica, the slopes of the Andes and a site in the Amazon rainforest of Eastern Ecuador, at the Tiputini Biodiversity Station 1 located adjacent to the Yasuní Biosphere Reserve. During many months of strenuous nightly field work, exposed to rain and mosquitoes, the researchers captured bats, identified species and recorded the total number of each species they captured. Based on these numbers, they calculated the species richness and diversity present in each of these forests.

US: NOAA Predicts Largest Gulf Of Mexico 'Dead Zone' On Record

NOAA-supported scientists from the Louisiana Universities Marine Consortium and Louisiana State University are forecasting that the "dead zone" off the coast of Louisiana and Texas in the Gulf of Mexico this summer could be the largest on record.

The researchers are predicting the area could measure a record 8,800 square miles, or roughly the size of New Jersey. In 2007, the dead zone was 7,903 square miles. The largest dead zone on record was in 2002, when it measured 8,481 square miles. The official measurement of this year's dead zone is slated to be released in late July. Researchers began taking regular measurements of the dead zone in 1985.

"The prediction of a large dead zone this summer is due to a combination of large influx of nitrogen and exceptionally high flows from the Mississippi and Atchafalaya rivers," said LSU scientist R. Eugene Turner.

The blaze is burning in grass and trees on the south part of the Army base. Authorities believe the fire was sparked by a lawn mower.

Fort Carson spokeswoman Brandy Gill says the Army base was notified of the blaze about 10 this morning. She says the fire is burning in grass and trees near the south part of the base. No structures are threatened.

Kamikatsu, Japan: Zero Waste

The Mayor of Kamikatsu, a small community in the hills of eastern Japan, has urged politicians around the world to follow his lead and make their towns "Zero Waste".

He told BBC News that all communities could learn from Kamikatsu, where residents have to compost all their food waste and sort other rubbish into 34 different categories.

Residents say the scheme has prompted them to cut down on waste generally and food waste in particular.

If the policy spread, it would reduce the amount of food waste, and so take some of the pressure off high food prices.

Kamikatsu may be a backwater in the wooded hills and rice terraces of south-eastern Japan but it's become a world leader on waste policy.

There are no waste collections from households at all. People have to take full responsibility for everything they throw away.

Brazil announces new offshore oil find

Brazil's state-controlled oil company Petrobras has announced the discovery of a high-quality off-shore oil deposit in the Espirito Santo Basin.

The new deposit is located in near the Golfinho field, 60 kilometers (40 miles) from the city of Vitoria, at a depth of 1,374 meters (about 4,500 feet). The first estimates indicate a potential of 150 million barrels of recoverable oil, Petrobras said in a press release posted on its website on Tuesday.
