Fine root chemistry and decomposition in model communities of north-temperate tree species show little response to elevated atmospheric CO 2 and varying soil resource availability
(Springer-Verlag, 2005-12)
Rising atmospheric [CO 2 ] has the potential to alter soil carbon (C) cycling by increasing the content of recalcitrant constituents in plant litter, thereby decreasing rates of decomposition. Because fine root turnover ...
Extracellular Enzyme Activities and Soil Organic Matter Dynamics for Northern Hardwood Forests receiving Simulated Nitrogen Deposition
(Kluwer Academic Publishers; Springer, 2005-08)
Anthropogenic nitrogen enrichment alters decomposition processes that control the flux of carbon (C) and nitrogen (N) from soil organic matter (SOM) pools. To link N-driven changes in SOM to microbial responses, we measured ...
An Integrated LCA-LCC Model for Evaluating Concrete Infrastructure Sustainability
(2005)
Cement, the key binding material in concrete, is vital to human infrastructure and the economy. We rely on its durability and versatility to build our roads, bridges, buildings and water and sewage systems. Despite its ...
Environmental Reporting for the University of Michigan Ann Arbor Campus: the U-M Environmental Data Repository
(2005-06-08)
In April of 2004, The University of Michigan Environmental Task Force (ETF) issued their advisory report to President Mary Sue Coleman. This report, included as Appendix A, proposed an environmental assessment and reporting ...
Life Cycle Model for Evaluating the Sustainability of Concrete Infrastructure Systems
(2005-06)
Concrete infrastructure systems require large capital investments and resource flows to construct and maintain. An integrated life cycle assessment and cost model was developed to evaluate infrastructure sustainability and ...
