WASHINGTON -- Ethanol is far from a cure-all for the nation's energy problems. It's not as environmentally friendly as some supporters claim and would supply only 12 percent of U.S. motoring fuel - even if every acre of corn were used. A number of researchers, the latest in a report Monday, are warning about exaggerated expectations that ethanol could dramatically change America's dependence on foreign oil by shifting motorists away from gasoline. As far as alternative fuels are concerned,...

DES MOINES, Iowa (AP) - Iowa is at risk of losing its state tree - the oak - and residents are being urged to plant more of them to keep them from disappearing.

The infected forests in British Columbia make up an area roughly 40 percent the size of Idaho.

In this study the possibilities of the North American oak (Quercus rubra L.) as an afforestation alternative in the Basque Country Autonomous Community were investigated.

The study centred on 6 plantations of various ages in Bizkaia, firstly studying the wealth of epigeous fungi...

Biologists studying a lethal blight of lodgepole pines in northwestern British Columbia present strong evidence in the September issue of BioScience that climate change is to blame for the outbreak. The blight, caused by the fungus Dothistroma septosporum, causes trees to lose their needles and, in the case of the British Columbia outbreak, eventually die. D. septosporum has long been recognized as a pathogen of pines, but although it is considered a serious disease of exotic plantations in...
