Interacting Microbe and Litter Quality Controls on Litter Decomposition: A Modeling Analysis
The decomposition of plant litter in soil is a dynamic process during which substrate chemistry and microbial controls interact. We more clearly quantify these controls with a revised version of the Guild-based Decomposition Model (GDM) in which we used a reverse Michaelis-Menten approach to simulate short-term (112 days) decomposition of roots from four genotypes of Zea mays that differed prim...
متن کاملLitter quantity and decomposition
The global terrestrial heterotrophic respiration is estimated at about 60 Gt C yr-1 (Schlesinger, 1991). Plant litter produced during senescence processes and plant residues left on site after harvest operations are the primary substrate for heterotrophic respiration in plant-soil ecosystems. They constitute both of aboveground and belowground plant parts. Substrate quality, together with the p...
متن کاملLitter quality, stream characteristics and litter diversity influence decomposition rates and macroinvertebrates
1. We examined the relative importance of litter quality and stream characteristics in determining decomposition rate and the macroinvertebrate assemblage living on autumnshed leaves. 2. We compared the decomposition rates of five native riparian tree species (Populus fremontii, Alnus oblongifolia, Platanus wrightii, Fraxinus velutina and Quercus gambelii) across three south-western streams in ...
متن کاملLitter decomposition in southern Appalachian black locust and pine-hardwood stands: litter quality and nitrogen dynamics
Litter decomposition in southern Appalachian black locust and pine-hardwood stands: litter quality and nitrogen dynamics. Can. J. For. Res. 18: 54-63. To compare litter decomposition and nitrogen (N) dynamics in 16-year-old black locust and pine-hardwood forest stands, weight loss, N concentration, and litter quality of the dominant species in each stand were monitored for 863 days, using litte...
متن کاملControls over leaf litter decomposition in wet tropical forests
T ropical forests play a substantial role in the global carbon (C) cycle and are projected to experience significant changes in climate, highlighting the im portance of understanding the factors th a t contro l organic m atte r decom position in this biome. In the tropics, high tem perature and rainfall lead to some o f the highest rates o f litter decom position on earth , and given the near-o...
