Litter controls of microbial community composition and function in forest soils

Creator:

Brant, Justin B.

Abstract:

Most carbon (C) transformations in soil are carried out by a diverse and complex soil microbial community. The size and composition of the soil microbial community is determined by poorly understood interactions between the quantity and chemical composition of plant inputs, as well as climate. Given the metabolic diversity of...

Hydro-biogeochemical coupling at the hillslope and catchment scale

Creator:

van Verseveld, Willem J.

Abstract:

The specific objectives of this dissertation are to determine subsurface flow behaviors across different antecedent wetness conditions from a top-down perspective and to mechanistically assess the hydrological controls on DOC and N transport at the hillslope and catchment scale. The study area is a small catchment where hillslopes issue directly...

Patterns of nitrogen fluxes in watersheds of the H.J. Andrews Experimental Forest, OR

Creator:

Vanderbilt, Kristin Lynn, 1967-

Abstract:

Seasonal and annual patterns of N fluxes and concentrations in streamwater in six conifer-dominated watersheds at the H.J. Andrews Experimental Forest, OR, were studied to gain insight into the factors that influence N retention in this ecosystem. Processes affecting N flux in streamwater differed between organic (DON) and inorganic (DIN;...

Response of soil microbial communities and nitrogen cycling processes to changes in vegetation inputs

Creator:

Brewer, Elizabeth Ann

Abstract:

Changes in the type and amount of plant inputs can occur gradually, as with succession, or rapidly, as with harvesting or wildfire. With global change it is anticipated that both gradual and immediate scenarios will occur at increasing frequency. Changes in vegetation inputs alter the quality and quantity of soil...
