Of all the biogeochemical cycles, nitrogen is the one most intimately and thoroughly associated with microbes. Essential and unique steps in the nitrogen cycle are performed by a wide array of bacteri...
The importance of Dissimilatory Nitrate reduction to ammonium (DNra) in the Nitrogen cycle of coastal ecosystems
Dissimilatory Nitrate Nitrogen cycle

Until recently, it was believed that biological assimilation and gaseous nitrogen (N) loss through denitrification were the two major fates of nitrate entering or produced within most coastal ecosyste...

We present research aimed at determining the role of soil structure in the organization of microbial communities in soil. We have focused on the microbial communities involved in functional roles with...
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it’s a major factor just a little farther out into Rhode Island Sound. Scientis...

Grazers may influence nitrogen (N) pools and alter N inputs and outputs (losses) to the
ecosystem in a number of ways. In this study, we evaluated N pools within the plant-soil system (0-30cm) and so...
