Farmed salmon could become an invasive species in forest streams

...System lands, but the locations of Atlantic salmon farms and the sightings of escaped salmon indicate that streams on four national forests may be at risk: the Tongass and Chugach NF in Alaska, and the Olympic and Mount Baker-Snoqualmie NF in Washington.

Scientists map air pollution using corn grown in US fields

...In summer 2004, UCI scientists collected corn from farms and gardens in 31 states, including Hawaii and Alaska. They chose corn because it is widely grown and, as an annual plant, all of its carbon is derived from a single growing season. The scientists avoided pollution point sources such as highways and ...

Salmon farms kill wild fish, study shows

New research confirms that sea lice from fish farms kill wild salmon. Up to 95 per cent of the wild juvenile salmon that migrate past fish farms die as a result of sea lice infestation from the farms. The results of the research have been publis...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...DOE scientists envision a future where vast poplar farms in regions such as the Pacific Northwest, the upper Midwest, and portions of the southeastern U.S. could provide a steady supply of tree biomass rich in cellulose that can be transformed by specialized biorefineries into fuels like ethanol. Other re...
