Temperature Sensitivity of Microbial Respiration of Fine Root Litter in a Temperate Broad-Leaved Forest
The microbial decomposition respiration of plant litter generates a major CO2 efflux from terrestrial ecosystems that plays a critical role in the regulation of carbon cycling on regional and global scales. However, the respiration from root litter decomposition and its sensitivity to temperature changes are unclear in current models of carbon turnover in forest soils. Thus, we examined seasona...
متن کاملabove and within a temperate broad-leaved forest canopy on hourly to seasonal time scales
Fluxes and concentrations of carbon dioxide and 13 CO 2 provide information about ecosystem physiological processes and their response to environmental variation. The biophysical model, CANOAK, was adapted to compute concentration profiles and fluxes of 13 CO 2 within and above a temperate deciduous forest (Walker Branch Watershed, Tennessee, USA). Modifications to the model are described and t...
متن کاملRelationship between Dead Trees with Soil Physico-chemical Properties and Earthworm in Mixed Broad-leaved Forest Stand (Case study: Sarcheshmeh Forest, Chaloos)
Dead trees protection, has a key role in structural and biogeochemical processes in forest ecosystems. Some aspects of dead tree dynamics have been carefully studied, but the kind and decay degree of dead trees and forest soil properties have not received enough attention. The aim of this research was to study the effect of a kind and decay degree of dead trees on soil mineral properties in the...
متن کاملStructural variation in current-year shoots of broad-leaved evergreen tree saplings under forest canopies in warm temperate Japan.
Stem length and leaf area of current-year shoots were measured in saplings of eight broad-leaved evergreen tree species growing under a forest canopy. Stem length varied over a range of one to two orders of magnitude within each species. In all species, both the number of leaves and the mean stem length between successive leaves were greater in longer shoots. Mean leaf size and stem length were...
متن کاملFine Root Productivity and Turnover of Ectomycorrhizal and Arbuscular Mycorrhizal Tree Species in a Temperate Broad-Leaved Mixed Forest
Advancing our understanding of tree fine root dynamics is of high importance for tree physiology and forest biogeochemistry. In temperate broad-leaved forests, ectomycorrhizal (EM) and arbuscular mycorrhizal (AM) tree species often are coexisting. It is not known whether EM and AM trees differ systematically in fine root dynamics and belowground resource foraging strategies. We measured fine ro...
