Soil C and N cycling in three semiarid vegetation types: Response to an in situ pulse of plant detritus by Hooker, Toby D., Stark, John M.

“…Plant detritus is an important source of labile C that drives soil microbial growth and regulates the balance of N mineralization and immobilization. In…”

Ecosystem N Distribution and δ15N during a Century of Forest Regrowth after Agricultural Abandonment by Compton, Jana E., Hooker, Toby D., Perakis, Steven S.

“…Stable isotope ratios of terrestrial ecosystem nitrogen (N) pools reflect internal processes and input–output balances. Disturbance generally increases N…”

Forest Ecosystem Carbon and Nitrogen Accumulation during the First Century after Agricultural Abandonment by Hooker, Toby D., Compton, Jana E.

“…Forests of the northeastern United States are expected to serve as a substantial sink for carbon (C) and nitrogen (N) as they recover from extensive clearing…”

Vegetation and moisture controls on soil carbon mineralization in semiarid environments by Norton, Urszula, Saetre, Peter, Hooker, Toby D, Stark, John M

“…Mechanisms of vegetation control on C mineralization in semiarid ecosystems are not well understood. We developed a series of model predictions for beneath the…”

Carbon flow from plant detritus and soil organic matter to microbes--linking carbon and nitrogen cycling in semiarid soils by Hooker, Toby D, Stark, John M

“…We used in situ (13)C-labeling of an annual grass to examine the decomposition rate and fate of detrital C over 17 mo in a sagebrush ecosystem. We coupled…”

Estimating CO(2) flux from snowpacks at three sites in the Rocky Mountains by McDowell, Nate G., Marshall, John D., Hooker, Toby D., Musselman, Robert

“…Soil surface CO(2) flux (F(s)) is the dominant respiratory flux in many temperate forest ecosystems. Snowpacks increase this dominance by insulating the soil…”
