Abstract:

Litter humification is an essential process of soil carbon sequestration in forest ecosystems, but the relationship between soil fauna and humic substances has not been well understood. Therefore, a field litterbag experiment with manipulation of soil fauna was carried out in different soil frozen seasons over one year in cold forests. The foliar litter of four dominated tree species was selected as Birch (Betula albosinensis), Fir (Abies fargesii var. faxoniana), Willow (Salix paraplesia), and Cypress (Juniperus saltuaria). We studied the contribution of soil fauna to the accumulation of humi

Abstract:

The decomposition dynamics of four types of needle litter and three types of leaf litter were followed for 4 years. Mass losses and certain chemical changes were studied. Most of the nutrient-rich litters appeared to decompose relatively quickly during the first 12–18 months. After 3–4 years, however, their accumulated mass losses were lower compared with litter types that intially had lower rates. Thus the more nutrient-rich litters had considerably lower mass-loss rates in the later stages. This pattern was even more pronouced for extract-free lignocellulose: its mass-loss rate was negativel

Abstract:

This study determined the rate of decomposition of fine roots and leaf litter from birch, larch, and pine, and compared the impact of fine root decomposition and leaf litter on carbon, nitrogen, and phosphorus accumulation in various regenerated and reconstructed forest ecosystems. The control plots were located on podzol soils in managed forest non-degraded habitats. Over a one-year experimental season, the decomposition of birch and larch fine roots released less carbon in comparison to leaf litter. The carbon mass-loss rates were 16% for birch roots and 15% for larch roots, while for birch

Abstract:

We investigated microfungal assemblages on leaf litter within a subalpine forest in central Japan and their variation with season, litter depth, and litter species. Microfungal assemblages were compared for Abies needles and Betula leaf litter collected from litter and fermentation layers of the forest floor during the growing season in spring, summer, and autumn. A total of 35 and 42 species were isolated from Abies needles and Betula leaf litter, respectively. The observed variation in microfungal assemblages was primarily attributable to seasonal differences. The frequencies of Trichoderma

Abstract:

A spatially explicit model of leaf litter fall was developed for hemlock–hardwood forests using litter-trap data from mapped forest plots and from isolated trees. The model assumes that litter declines exponentially with distance, as shown by the litter traps from isolated trees, and that a variable allometric equation describes the relationship of DBH to foliage biomass. Model parameters were estimated by a maximum likelihood method using field data from one mapped plot and then tested on a second plot.

AbstractLitter decomposition produces labile and recalcitrant forms of dissolved organic matter (DOM) that significantly affect soil carbon (C) sequestration. Chemical analysis of this DOM can provide important knowledge for understanding soil DOM dynamics, but detailed molecular analyses on litter derived DOM are scarce. Here we use ultrahigh resolution mass spectrometry (FT-ICR MS) to characterize the molecular composition of DOM from fresh and progressively decomposed litter samples. We compared high reactive (HR) and low reactive (LR) litter sources with regard to changes in the chemistry

Research Highlights: Direct comparison of leaf litter decomposition rates between harsh soil conditions of degraded lands and adjacent “closer to natural” forest areas has not been done before. Background and Objectives: We aimed to fill this knowledge gap by determining the differences in amounts of carbon and nitrogen released by species-specific litter depending on decomposition rates in various stand and habitat conditions, which enables selection of the most ecologically and economically appropriate (for fast soil organic layer development) tree species for afforestation of reclaimed land

The objective of this study was to improve our understanding of the role of soil invertebrates in the breakdown of litter, cycling of nitrogen, and growth of seedlings in forests of British Columbia by comparing two experimental approaches. First, in the laboratory, breakdown of birch leaves was slightly higher in the presence of millipedes in the microcosms of forest floor collected from two coastal forests. Presence of smaller animals (mesofauna) and contaminant Diptera larvae did not hasten litter breakdown in microcosms made from forest floor from either a sub-boreal or a coastal forest. I

The greenhouse experiment included three seeding densities, four litter thicknesses covering the seeds, and two substrate types.

Abstract:

Abstract The process of abandonment of arable land seems to be one of the main factors of changes in landscape and soil properties. This problem occurs on nearly 10% of arable land in Poland. The natural aspect of transformation is connected with the entrance of birch trees on uncultivated land and the anthropogenic aspect is associated with pine plantations. In the beginning, the appearance of trees on the former arable land changes soil properties because soil (and plant) is the most dependent component of the natural environment. In this paper, the role of birch and pine was analysed in com

Twenty site types were distinguished in the vegetation transect across the Qingua-dalen.

Notably, the fallow land, in contrast to the forested areas, exhibited a significant loss of organic carbon from the soil, amounting to up to 83 % within a 30 cm depth due to the exploitation of forest resources.
