Evaluating the gas we pass

Ecologists are embracing the potential to increase the storage of carbon in terrestrial ecosystems. This could reduce the build-up of carbon dioxide in Earth's atmosphere. But does it?

Beavers take a chunk out of nitrogen in Northeast rivers

Beavers, once valued for their fur, may soon have more appreciation in the Northeastern United States. There they are helping prevent harmful levels of nitrogen from reaching the area's vulnerable estuaries. By creating ponds that slow down the movement of water, they aid in removing nitrogen from the water.

Leave leaves alone

Podcast

In natural ecosystems, there is little waste. Nutrients taken up by plants are returned to the soil when plants die and decompose. Ecologists call this nutrient loop a biogeochemical cycle.

Warming the tundra

Podcast

A lot of dead plant material is stored in the tundra soils of the far north. Most of it is frozen in permafrost, and inaccessible to the microbes that normally decompose organic matter in soils.

Base Cation Depletion: Organic Matter Quality & Microbial Processes

We are analyzing how changes in soil base status can influence microbial physiology, organic matter quality, and microbial activity in northern hardwood forests at Hubbard Brook.

Snow Depth & Soil Freezing as a Regulator of Microbial Processes

In the northern hardwood forests in New Hampshire we are analyzing how soil freezing events cause root and microbial mortality, which can lead to increased rates of N and P mineralization and loss.
