Journal ArticleDOI
Analysis of factors controlling soil organic matter levels in Great Plains grasslands
TL;DR: In this article, a model of soil organic matter (SOM) quantity and composition was used to simulate steady-state organic matter levels for 24 grassland locations in the U.S. Great Plains.
Journal ArticleDOI
Novel ecosystems: theoretical and management aspects of the new ecological world order
Richard J. Hobbs,Salvatore Arico,James Aronson,Jill S. Baron,Peter Bridgewater,Viki A. Cramer,Paul R. Epstein,John J. Ewel,Carlos A. Klink,Ariel E. Lugo,David A. Norton,Dennis S. Ojima,David M. Richardson,Eric W. Sanderson,Fernando Valladares,Montserrat Vilà,Regino Zamora,Martin Zobel +17 more
TL;DR: The issues relevant to those types of ecosystems containing new combinations of species that arise through human action, environmental change, and the impacts of the deliberate and inadvertent introduction of species from other regions are explored.
Journal ArticleDOI
Observations and modeling of biomass and soil organic matter dynamics for the grassland biome worldwide
William J. Parton,J. M. O. Scurlock,Dennis S. Ojima,T. G. Gilmanov,Robert J. Scholes,David S. Schimel,Thomas B. Kirchner,J. C. Menaut,Timothy R. Seastedt,E. Garcia Moya,Apinan Kamnalrut,Jenesio I. Kinyamario +11 more
TL;DR: The Century model as mentioned in this paper is a model of terrestrial biogeochemistry based on relationships between climate, human management (fire, grazing), soil properties, plant productivity, and decomposition.
Journal ArticleDOI

TL;DR: Solutions to the nutrient challenges that face global agriculture can be informed by analyses of trajectories of change within, as well as across, agricultural systems.
Journal ArticleDOI
Climatic, edaphic, and biotic controls over storage and turnover of carbon in soils
David S. Schimel,Bobby H. Braswell,Elisabeth A. Holland,Rebecca McKeown,Dennis S. Ojima,Thomas H. Painter,William J. Parton,Alan R. Townsend +7 more
TL;DR: In this paper, the Century ecosystem model was applied to a series of forest and grassland sites distributed globally to examine large-scale controls over soil carbon, including soil texture and foliar lignin content.
