Scientists are in a race against time to stifle the spread of a fungal disease that has killed tens of thousands of stately oak trees in California and southwestern Oregon. Many people fear it may spread and similarly wipe out large swaths of forest in the eastern United States and Canada.
Researchers have confirmed a long-suspected link between logging and the devastation of forest fires in tropical rain forests. A German and Indonesian team who studied the forest fires that burned more than 12 million acres (5 million hectares) in East Kalimantan, Indonesia, in 1998 found that the worst damage by far was in recently logged areas.
In the early 1900s Argentine ants hitched a ride on merchant ships that carried goods to several continents. Their invasion has wiped out native populations of ants in some areas, with damaging effects across ecosystems, a new study shows.
Coral reef team with a mind-boggling array of life in waters that are often nutrient poor. Researchers say they may have found the answer to this paradox that has intrigued scientists since the famous voyages of Charles Darwin.
Scientists and satellites are helping to change the land-use practices in the Peruvian rain forest. An economy once based on unsustainable levels of logging is shifting to one based on ecotourism and the sustainable harvesting of medicinal plants.
Louisiana's innovative Alligator Marsh to Market commercial harvesting program has proven to be an effective conservation tool, according to state officials. It protects alligator populations and preserves critical wetlands habitats while providing about U.S. $54 million of economic benefits to the state each year.
Deforestation in Costa Rica's lowlands is reducing the cloud cover over the Monteverde cloud forest, threatening the health of the unique ecosystem at higher altitudes. The finding is disturbing to scientists and conservationists because cloud forests harbor an astounding array of plants and animals found nowhere else in the world.
In an expedition to the remote Raja Ampat Islands off Indonesia's province of Irian Jaya, scientists have found what appears to be an unparalleled array of marine speciescorals, fishes, and mollusksincluding some never seen before.
The collapse of many of the world's coastal marine ecosystems is usually blamed on modern human impacts such as pollution, increased nutrient runoff, and global warming. Now, a team of international researchers says the problem also has roots in overfishing hundreds if not thousands of years ago.
There's a high chance that the world's population will stop growing by the end of the 21st century, according to a new study. It predicts that the total number of people may peak in 70 years or so at about 9 billion people, compared with 6.1 billion today. The authors of the report attribute the rosier-than-usual outlook to successful efforts in the last few decades to curb fertility rates.
As water resources grow increasingly scarce, threatening the way of life for billions of people around the world, a number of scientists argue that there can be enough for everyone if communities give it its proper economic value.
