Abstract Soil carbon turnover models generally divide soil into pools with varying intrinsic decomposition rates. Although these rates are modified by factors such as temperature, texture, and moisture, they rationalized assuming chemical structure is a primary controller of decomposition. In the current work, we use near edge X‐ray absorption fine (NEXAFS) spectroscopy in combination differential scanning calorimetry (DSC) alkaline cupric oxide (CuO) oxidation to explore this assumption....
Abstract Alterations in forest productivity and changes the relative proportion of above‐ belowground biomass may have nonlinear effects on soil organic matter (SOM) storage. To study influence plant litter inputs SOM accumulation, Detritus Input Removal Transfer (DIRT) Experiment continuously alters to by a combination trenching, screening, addition. Here, we used biogeochemical indicators [i.e., cupric oxide extractable lignin‐derived phenols suberin/cutin‐derived substituted fatty acids...
Forest managers in the United States must respond to need for climate-adaptive strategies face of observed and projected climatic changes. However, there is a lack on-the-ground forest adaptation research indicate what measures or tactics might be effective preparing ecosystems deal with climate change. Natural resource many areas are also challenged by scant locally regionally relevant information on projections potential impacts. The Adaptive Silviculture Climate Change (ASCC) project was...
Abstract The importance of forests for sequestering carbon has created widespread interest among land managers identifying actions that maintain or enhance storage in forests. Managing forest under changing climatic conditions underscores a need resources help identify adaptation align with management. We developed the Forest Carbon Management Menu to translate broad management concepts into actionable tactics reduce risk from expected climate impacts order meet desired goals. describe...
Mineral stabilization of soil organic matter is an important regulator the global carbon (C) cycle. However, vulnerability mineral-stabilized (OM) to climate change currently unknown. We examined profiles from 34 sites across conterminous USA investigate how abundance and persistence mineral-associated C varied with at continental scale. Using a novel combination radiocarbon molecular composition measurements, we show that relationship between (MAOM) appears be driven by moisture...
Abstract Our research takes advantage of a historical trend in natural reforestation abandoned tropical pastures to examine changes soil carbon (C) during 80 years secondary forest regrowth. We combined chronosequence approach with differences the abundance 13 C between C3 (forest) and C4 (pasture) plants estimate turnover times bulk density fractions. Overall, gains were compensated for by loss residual pasture‐derived C, resulting no net change stocks down 1 m depth over chronosequence....
Temperate forest soils store globally significant amounts of carbon (C) and nitrogen (N). Understanding how soil pools these two elements change in response to disturbance management is critical maintaining ecosystem services such as productivity, greenhouse gas mitigation, water resource protection. Fire one the principal disturbances acting on C N storage also subject enormous efforts. In present article, we use meta-analysis quantify fire effects temperate storage. Across a combined total...
Afforestation (tree establishment on nonforested land) is a management option for increasing terrestrial C sequestration and mitigating rising atmospheric carbon dioxide because, compared to land uses, afforestation increases storage in aboveground pools. However, because ecosystems typically store most of their soils, impacts soil organic (SOC) are critical components ecosystem budgets. We applied synthesis methods identify the magnitude drivers SOC, temporal vertical distributions SOC...
Soils are Earth's largest terrestrial carbon (C) pool, and their responsiveness to land use management make them appealing targets for strategies enhance C sequestration. Numerous studies have identified practices that increase soil C, but inferences often based on limited data extrapolated over large areas. Here, we combine 15,000 observations from two national-level databases with remote sensing information address the impacts of reforestation sequestration in topsoils (uppermost mineral...
There is an ever-growing body of literature on forest management strategies for climate change adaptation; however, few frameworks have been presented integrating these with the real-world challenges management. We developed a structured approach translating broad adaptation concepts into specific actions and silvicultural practices adaptation, as well associated set resources to assist managers in using this approach. A variety public, private, nongovernmental, tribal natural resource are...
