Abstract:

The aim of the study was to examine whether the variation in needle longevity of Scots pine (Pinus sylvestris L.) is of a community-specific nature. Altogether 300 trees were examined in Vaccinium, dry heath, and pine bog forests in Estonia. Mean number of needle age-classes was 4.1 for all forest types, while mean survivorship of needles averaged 70% in Vaccinium forests and 80% in the others (p < 0.01). Mean mass-based nitrogen content (Nm) of the needles was the highest in Vaccinium forests (11.8 mg·g1, p < 0.05) and lower in dry heath (10.4 mg·g1) and pine bog (9.8 mg·g1) forests.

AbstractPeat bogs are among the most threatened habitats in Central Europe. They are characterized by stagnant water with low pH and lower nutrient content compared to the surrounding habitats. The flora and fauna of peat bogs comprised of many habitat specialist and rare species. We explored the differences in spider fauna of European spruce and Scots pine forests. Furthermore, we assessed the effect of microhabitat diversity in the bog forests of the Poiana Stampei peat bog complex, Bucovina, Romania. We collected numerous rare and cold-adapted species. .We found a strong effect of forest ty

Abstract Every year the Republic of Croatia, especially in its south part in Dalmatia, faces forest fire risks. The weather is exceptionally conducive to fires, so the main period of fire occurrences is between June and October, characterized by long lasting dry and warm weather with temperatures over 30°C. Research carried out by the authors in 1997 and 2012 have pointed to the fact that human impact is the main cause of ignition. This paper presents an overview of the total number of fires in the period from 1998 to 2012, with the emphasis on forest and woodland fires in the Croatian region

Abstract:

One of the objectives of this review of recent trends in fires in boreal and tropical forests is to raise reader awareness of wilderness fires as a type of disaster mainly caused by human activity. Fires occurring in different vegetative areas are usually named for the vegetation in which they occur, e.g., forest fires, bush fires, savanna fires, and peat or bog fires. The term "wildland fire" represents all such fires. Despite the widespread occurrence of such fires, the International Association of Wildland Fires (IAWF) is the only international association covering vegetation conflagrations

Mapping the regional distributions of its population characteristics can be beneficial in the management of its natural resources, and this mapping should be predicted using machine learning modeling to obtain accurate results.

Three contrasting ecosystems—pine forests with Albic Podzols; palsa with Histic Oxyaquic Turbic Cryosols, and bogs with Fibric Histosols—predominate in this area. The objectives of the study included evaluation of the CO2 emission from soils in the growing seasons of 2019–2022 and analysis of the factors controlling spatial and interannual variability of the emission. The study included analysis of the soil respiration (static clos

Abstract:

Northern peatlands store large amounts of carbon. Observations indicate that forests and peatlands in northern biomes can be alternative stable states for a range of landscape settings. Climatic and hydrological changes may reduce the resilience of peatlands and forests, induce persistent shifts between these states, and release the carbon stored in peatlands. Here, we present a dynamic simulation model constrained and validated by a wide set of observations to quantify how feedbacks in water and carbon cycling control resilience of both peatlands and forests in northern landscapes.

Abstract:

The Lake Sixteen peatland is a 400-ha mire consisting principally of low-shrub (Chamaedaphne) bog and lesser areas of tree-covered (Picea – Larix) bog and sedge fen adjacent to a 55-ha alkaline lake. The sediments consist of the following superimposed deposits: gyttja, sedge peat, and Sphagnum–ericad–sedge peat. Near the edges of the peatland, highly humified, sometimes woody peat is present as the basal layer instead of gyttja. Radiocarbon-dated pollen stratigraphies from the lake and four sites in the peatland have elucidated the temporal relationships of the various sediment units and the d

AbstractSince ancient times, climate change has largely determined the fate of human civilisation, which was related mainly to changes in the structure and habitats of forest cover. In the context of current climate change, one must know the capabilities of forests to stabilise the climate by increasing biomass and carbon-depositing abilities. For this purpose, the authors compiled a database of harvest biomass (t/ha) in 900 spruce (Picea spp.) sample plots in the Eurasian area and used the methodology of multivariate regression analysis.

It is established that open spruce-birch forests were widespread during the Aller d and Younger Dryas. Since the Preboreal stage of the Holocene, a peat bog began to form surrounded by pine and birch forests with spruce. The Boreal stage was marked by an increased role of br

Background and Objectives: Black spruce and aspen are found across the boreal forest with black spruce dominating lowlands and aspen being common in uplands. Both species are well adapted to wildfire with black spruce holding an aerial seedbank while aspen reproduce rapidly via root suckering. In the summer

Abstract:

Fires in forested raised bogs occur both as a result of natural processes and as a result of human activity. Although there is a generally accepted opinion that their impact on ecosystems is significant, there is still a lack of scientifically reliable research on how individual components of damaged ecosystems change and recover under the influence of fires. The purpose of our study was to assess whether and how these fires affect the chemical composition of the peat layers. This study is based on a geochemical analysis of surface peat layers in areas after a controlled fire and in adjacent a

Peatland species are endangered because of peat extraction and drenching of peatland in many regions, and thus are of great conservation concern. Often times, the trait of being "tyrphobiontic" or "tyrphopilous" is defined differently in the literature, yielding ambigous results. Frequently, studies of peatland fauna do not clearly define which species are characteristic of peatlands, instead focussing on other traits like red data book status etc. The group of peatland specialists should be definied by their affinity to the habitat trait of peaty soil.

Oil production and transportation activities during the development of the Samotlor field are accompanied by pollution of the territory and degradation of vegetation, and a reduction in forest areas.
