Altered bacterial community structure of Chronic N-amended soils of hardwood stand at Harvard Forest, MA, USA

Poster Number:  123 Presenter/Primary Author:  Rakesh Minocha At the Harvard Forest, Petersham, MA, the impact of twenty years of annual ammonium nitrate application on the forest soil bacterial communities was studied using pyrosequencing of 16S rRNA genes.

Microbes, moisture, and metabolic activity: Is there a soil moisture threshold for microbial activity?

Poster Number:  121 Presenter/Primary Author:  Sarah Placella Growing evidence suggests that climate-driven changes in precipitation regulate microbially mediated ecosystem processes, such as CO2 flux from soils to the atmosphere.

Getting to the root of the matter: Fire effects on mycorrhizal seedling establishment and tree migration in Alaska

Poster Number:  81 Presenter/Primary Author:  Rebecca Hewitt Fire is the primary landscape-scale disturbance in the boreal forest, and in the last half-century fires have increased in severity and extent in the boreal forest and tundra.

Microbial Ecology of the WAP Continental Shelf Region

Poster Number:  68 Presenter/Primary Author:  Hugh Ducklow We present results from a large data set (N=5427 individual measurements at 449 stations, 2003-2012) on bacterial abundance and production and related hydrographic properties collected on ten, regi
