Diversification Key to Resilient Fishing Communities

Sat, 14 Jan 2017 05:00:00 EST

(image) Fishing communities can survive ― and even thrive ― as fish abundance and market prices shift if they can catch a variety of species and nimbly move from one fishery to the next, a new University of Washington study finds.(image)






Study of Microbes Reveals New Insight About Earth's Geology and Carbon Cycles

Fri, 13 Jan 2017 15:05:31 EST

(image) Tiny microbes play a big role in cycling carbon and other key elements through our air, water, soil and sediment. Researchers who study these processes at Argonne National Laboratory have discovered that these microbial communities are significantly affected by the types of carbon "food" sources available. Their findings reveal that the type of carbon source affects not only the composition and activity of natural microbial communities, but also in turn the types of mineral products that form in their environment.(image)
