CAB Direct platform is the most thorough and extensive source of reference in the applied life sciences, incorporating the leading bibliographic databases CAB Abstracts and Global Health. Litter decomposition is a key ecological process responsible for the release of nutrients from litter and is controlled by the three main factors of environmental conditions, decomposer community, and substrate quality [1,2,3].In general, climate (especially temperature and moisture) governs the decay rates at broad regional scales, whereas initial litter quality variables (carbon/nitrogen.
The present paper is based on the study of Scots pine trees from the provenance trials established in southern taiga and forest-steppe, Central Siberia (58 0 N, 97 0 E and 57 0 N, 93 0 E). In and the Laboratory of Forest Genetics and Breeding of the Institute of Forest led by A.I. Iroshnikov, L.I. Milyutin and N.A. Kuzmina raised. consequence of climate change. On those sites tree litter dynamics may be crucial for the C balance. We studied the decomposition of Scots pine (Pinus sylvestris L.) needle and root litter in boreal peatland sites representing gradients in drainage succession (succession following.
Element content of Scots pine (Pinus sylvestris L.) stands of different densities 79 ple plot, 3 model trees, representing the entire range of tree diameters, were cho-sen (fig. 1). The 15 model trees selected were then cut down, divided into tree parts – the stem, branches, needles and . The colonization and lignin decomposition of pine (Pinus thunbergii and Pinus densiflora) needle litter by an endophytic fungus, Lophodermium pinastri, was examined with field observations, a field experiment and laboratory pine needles collected from the field, needle mass per length and lignin content were lower in needle portions bearing Lophodermium fruiting bodies than in.

Litter bags with a unified substratum of Scots pine needles were used at 16 sites, differing in climate and other environmental conditions along a NW-European transect. The soil climate was simulated by a physically based model using meteorological data and Cited by: 6.
Climatic influence on decomposition of Scots pine needle litter along a NW European transect. Rep Department of Ecology and Environmental Research. Swedish University of. —A transect (No. II) with Scots pine stands on sediment soil, in which unified Scots pine needle litter was incubated annually for a period of approximately 6 to 19 years.
The transect had 13 sites between northernmost Finland (69°45′N) and central Holland (52°02′N) and had highly standardized sites with nutrient‐poor Scots pine stands on sandy sediments and thus on flat by: 2. Decomposition of Scots pine (Pinussylvestris L.) needle litter was studied at 14 sites along a climatic transect through Sweden.
The forests encompassed a wide range of the variability in site properties found in the country. Scots pine litter decomposition along drainage succession and soil nutrient gradients in peatland forests, and the effects of inter-annual weather variation.
Soil Biology and Biochemistry ; Keywords: Climate change, needle litter, organic matter decomposition, peatlands, Pinus sylvestris, root litter, weather variations. Future attempts to model the effect of climate on broad-scale decomposition rates of Scots pine needles (and probably plant litters in general) need to include a seasonal factor.
For a given mass-loss value (10, 20, 30, 40 or 50%), the proportion of lignin, cellulose, hemicelluloses, non-structural compounds, N and ash in the decomposing pine needles differed between sites (Fig. 2).Cited by: The decomposition and organic chemical changes in Scots pine (Pinus silvestris) needle litter were studied for a period of 5 years and until 75% weight loss was reached in field incubation.

For Scots pine needle litter the effect of MAT on mass loss decreased with increasing accumulated mass loss and changed to a rate-dampening effect at c.

Nitrogen dynamics of decomposing Scots pine needle litter depends on colonizing fungal species Decomposition of Scots pine needle litter was studied in axenic microcosms with the ligninolytic litter decomposing basidiomycete Gymnopus androsaceus or the stress Carbon and nitrogen dynamics along the decay continuum: plant litter to soil.

In the early stages of decomposition (Scots pine needles decomposed faster than those of lodgepole pine (p days) there was no difference in the decomposition rate. Combining both species, mass‐loss rates were positively correlated to concentrations of water solubles and.
In order to evaluate effects of climate change on litter chemistry, needle litter was collected from Scots pine (Pinus sylvestris L.) saplings exposed to elevated CO 2 or O 3 concentration and their combination over three growing seasons in open‐top chambers. The decomposition of needle litter was followed for 19 months in a pine forest.
Newly shed foliar plant litter often has a decomposition rate of ca –% day−1, which decreases greatly with time and may reach to % day−1 or lower in litter material in the last stages of decay.
The decrease in decomposability (substrate quality) varies among species and is complex, involving both direct chemical changes in the substrate itself and the succession in. Abstract. Needle litter from 14 stands of Scots pine (Pinus silvestris, L.), 13 stands of Norway spruce (Picea abies (L.) Karst.) and leaf litter from three stands of white birch (Betula pubescens Ehrh.) were analysed for chemical concentrations of the elements N, P, K, Ca, Mg and Mn as well as solid organic components (lignin, cellulose and hemicelluloses) and solubles were.
