Logging of the largest trees in the Sierra Nevada’s national forests ended in the early 1990s after agreements were struck to protect species’ habitat.

Researchers study impact of ice storms, climate change

Some avian influenza, or bird flu, viruses that are able to enter North America from other continents through migrating birds can be deadly to poultry and can infect waterfowl populations, according to a recently published U.S. Geological Survey study.

A compound found in seaweed could protect human skin from the damaging impact of the sun without causing harm to marine ecosystems. 

Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences.

Trees in California communities are working overtime. From removing carbon dioxide and pollutants from the air, intercepting rainfall and increasing property values, California's 173.2 million city trees provide ecosystem services valued at $8.3 billion a year. However, according to a recent study, more benefits could be realized if the Golden State's urban forests didn't have the lowest canopy cover per capita in the nation.

NASA's Terra satellite passed over the Arabian Sea on Dec. 4 and found Tropical Cyclone Ockhi moving north as desert dust pushed into the region north of the storm.

About 40 percent of northern Malaysian Borneo’s carbon stocks exist in forests that are not designated for maximum protections, according to new remote sensing and satellite mapping from Carnegie’s Greg Asner and his colleagues.

Detailed global maps of key traits in higher plants have been made available for the first time, thanks to work led by researchers from the University of Minnesota’s (UMN) College of Food, Agriculture and Natural Resource Sciences (CFANS).

The arrival 36 years ago of a strange bird to a remote island in the Galápagos archipelago has provided direct genetic evidence of a novel way in which new species arise.

On Nov. 23 in the journal Science, researchers from Princeton University and Uppsala University in Sweden report that the newcomer belonging to one species mated with a member of another species resident on the island, giving rise to a new species that today consists of roughly 30 individuals.
