Changes in soil invertebrate decomposer communities during regeneration of Scots Pine within the Abernethy Forest Reserve, Scotland
… invertebrates. This research looks at effects of Scots pine (Pinus sylvestris) regeneration on the meso- and macro- soil invertebrate communities. Within the Abernethy Forest Reserve (the largest remaining tract of native Scots pine woodland within the UK) mature woodland (pine-dominated) and …

Sýkingarmætti grágeitarsveppsins Ophiostoma clavatum í fræplöntum skógarfuru
… of the blue stain fungus Ophiostoma clavatum in Scots pine (Pinus sylvestris) seedlings was explored. Following climate change, in recent decades, an increased severity of the bark beetle Ips acuminatus attacks on Scots pine has been observed, both in Finland and in the alpine regions of Europe. …

The Influence of Trees on Soil Hydraulic Properties : Species Effects and the Provision of Ecosystem Services.
… effect of a broadleaf (sycamore) and a conifer (Scots pine) tree on Ks to determine if this differs between species type, to examine the effect of land use on Ks under forest cover and to investigate the key underlying mechanisms involved. Results showed significantly higher Ks under undisturbed …

The hydrological effects of changes in forest area and species composition in the federal state of Brandenburg, Germany
… implemented forest module has been tested for Scots Pine (Pinus sylvestris) and in parts for Common Oak (Quercus robur and Q. petraea) in Brandenburg. For Scots Pine the results demonstrate a good simulation of annual biomass increase and LAI in addition to the satisfactory simulation of litter …

An investigation of the durability of UK grown softwood distribution poles CCA-treated by sap-displacement
The decay susceptibility of UK grown Corsican pine, Scots pine, Norway spruce and Sitka spruce poles treated with CCA by the high pressure sap-displacement process, was investigated using full size poles in a field site and representative pole sections in an accelerated decay …

Changes in soil properties under experimental tree plots on the Isle of Rum
… of birch (Betula spp.), oak (Quercus spp.) and Scots pine (Pinus sylvestris) growth on the relatively fertile, mineral soils at Harris and the less fertile, organic soils at Kilmory Fank. Significant changes in soil characteristics were identified beneath all three species growing on both soil …

Use of biological agents to enhance the preservative treatment of electrical distribution poles
… timbers. The preservation of Sitka spruce and Scots pine heartwood by conventional methods is poor with the depth of preservative penetration being only a few millimetres.<br/><br/>The use of <i>Trichoderma </i>isolates to improve the permeability, of such timbers provides a novel approach to …

Initial Assessment of Canopy Fuel Factors in Forested Areas of the Netherlands
… (<em>Pseudotsuga menziesii </em>(Mirb.) Franco), Scots pine<em> </em>(<em>Pinus sylvestris </em>L.), and black pine<em> </em>(<em>Pinus nigra </em>Arn.) to be used in fire models estimating canopy fire behavior in that country. Leaf area index, gap fraction, and canopy bulk density were estimated …

Molecular distributions and hydrogen isotopic compositions of n-alkanes from field studies of tree species: applications for paleoclimate studies
… species. Using an in-depth investigation of Scots pine (Pinus sylvestris), significant variations in n-alkane molecular distributions and δD values were detected. These results suggest height of sample collection within a natural forest exerts a strong control on both n-alkane compositions, …

Nitrogen deposition and nitrification in coniferous forests’
… on Norway spruce (Picea abies [L.] Karst) and Scots pine (Pinus sylvestris L.) fine roots, and c) the controls of nitrification in an acid forest soil. The work was part of the CEC project ‘CORE’, investigating the effects of atmospheric pollution on nutrient turnover in soils. An identical …

Environmental and efficacy studies of a chromated fluoride wood preservative
… in creosoted electricity distribution poles of Scots pine (<b><i>Pinus sylvestris</i></b>) are caused by decay of uncreosoted sapwood and heartwood of the interior groundline region. To eradicate the basidiomycetes responsible for this decay a waterborne chromated fluoride preservative paste, …

Sequestration and Characterization of Soil Organic Carbon for Shelterbelt Agroforestry Systems in Saskatchewan
… (Acer negundo), white spruce (Picea glauca), Scots pine (Pinus sylvestris) and caragana (Caragana arborescens) and the adjacent agricultural fields at 59 sampling sites across the agricultural region of Saskatchewan. Measurement of SOC concentration for soil samples was preceded by fumigation …

Potential of temporal and spatial analysis techniques as tools for exploring changes in forest site productivity and following environmental interactions : Finnish-German comparative study
… of Norway spruce (Picea abies L. Karst) and Scots pine (Pinus sylvestris L.) were used in to describe and model the sites with clear change of site quality, but also to find relationships between spatial patterns and space-time trajectories in forest growth deviations and potential causes of …

Influencia de la luz y la sequía estival en la respuesta funcional de brinzales de Quercus petraea (Matt.) Liebl. y Quercus pyrenaica Willd. : implicaciones para la regeneración
… plantations carried out in gaps, clearings and Scots pine stands close to a beech-oak forest in Montejo de la Sierra (NE Madrid, Spain). This could be so because variation of understory light availability generated by the distinct canopy-tree densities was related to the variation of seedlings’ …

Investigation of lead and zinc dispersion from an abandoned mine site at Tyndrum, Scotland
… Pb and Zn concentrations in tree bark from Scots pine (Pinus sylvestris) were high, but decreased with increasing distance up to approximately 100 m from the main dumpsite. Concentrations reduced markedly beyond this distance, possibly owing to the density of the forest stand. It is …
