Climate change is a topic of worldwide relevance, not only because of the recent heat waves affecting the globe as a whole but also because of the importance of conserving the ecologically balanced environment itself. Climate is a vital aspect of human survival and ecological balance. With this in mind, the world is turning its attention to Brazil and the Amazon rainforest, the target of recurrent attacks that have resulted in high percentages of deforestation. It is known that since the signing of the Amazon Coop...

The article presents the results of satellite remote sensing to assess the consequences of hostilities in nature protected areas. Since February 24, 2022, 20% of the nature reserve fund of Ukraine has suffered from the war. The real level of damage to the objects of the nature reserve fund as a result of the war cannot be estimated. After all, active hostilities continue, and restrictions are created for environmental activities in the temporarily occupied territories. Therefore, remote monitoring is the only tool...

It is well known that woodpeckers and their distribution is mostly affected by deadwood. However, in Latvia there have not been any studies about how other forest structural components like growing trees and vegetation can affect distribution of woodpeckers and their choice of habitats. In recent years estimation of ecosystem services has become popular in Latvia and it is used in nature conservation matters. The aim of the research was to analyse structures characterizing the habitats of broadleaf forests and ide...

Forests provide humanity with essential raw materials, and the demand for these materials is growing, especially in conditions where it is necessary to replace the use of fossil resources with renewable ones. Latvia-s import of timber from Russia and Belarus has increased 8 times in 2021, when comparing 2013, reaching 33% of timber import value. Current geopolitical situation and supply chain sustainability calls for necessity to evaluate possibility to reduce the dependency on the timber import from Russia and Be...

Forest ecosystems are essential when dealing with climate change mitigation goals. Carbon stock of forest stand can hold substantial amounts of carbon as well products made from wood provide substitution effect, reducing reliance on fossil fuels. Silvicultural practices, such as drainage, have proven to be highly efficient of enhancing tree volume, aligning with climate change mitigation goals. As forest drainage disruption for rewetting of drained areas gains momentum with appealing goals such as enhancing biolog...

The main objective of this study is to analyze the demographic structure and spatial distribution of Quercus canariensis populations in the Ouled Bechih forest in northeastern Algeria. Knowledge of these parameters is an essential step in their sustainable management. Sample inventory plots measuring 30m x 30m (900m2) were identified by random sampling. Tree diameter at 1.30 m above the ground and total height of Q. canariensis were measured for each tree in four inventory plots. The demographic structures were es...

Bogs of Darwin Biosphere reserve (southern NW Russia) represent sustain ecosystem balance on an outstandingly large scale. Dynamics of the bog metabolism and structure should be estimated both under the influence of the Rybinsk reservoir and beyond it (in terms of natural evolution), although these cannot always be distinguished clearly. Forested bog areas are most sensible ecosystems to trace decadal or centennial dynamics of the landcover. Longstanding observations of the geobotanical and forest structure have b...

In this study, we conducted the plant population investigations in the Goettingen forest, located in Low Saxony, Germany, from 2022 to 2023. Our research focused on six distinct populations of Stellaria holostea L. across six plots within the forest. These plots encompassed varying tree species and forest management conditions, including a young beech managed forest (Plot #1), a virgin beech forest (Plot #2), and four managed old beech forest plots (Plots #3-6) subjected to different anthropogenic influences. To a...

Identification and quantification of the factors that influence genetic diversity is particularly important for the representatives of the genus Quercus L. In this genus, the characterization of the genetic diversity correlations can serve as a basis for predictive models of its distribution. The adaptive and neutral genetic variability of four autochthonous oak species (Quercus petraea (Matt.) Liebl. - sessile oak, Q. pubescens Willd. - pubescent oak, Q. frainetto Ten. - Hungarian oak, Q. cerris L. - Turkey oak) ...

The litterfall (fallen leaves, flowers, fruits and twigs) in the forests represents part of dead plant mass. The quantity and quality of litterfall in forests plays an important role in their state. Through it, a large part of chemical elements is returned to the cycle of the ecosystem, it is an essential carbon depot, it affects regeneration, soil moisture, fertility, composition, fauna and flora. The study presents data on stocks of chemical elements in annual literfall of Western Stara planina. The sample plots...

From a lithological point of view, the studied territory - Central Heating System of Rovinari is made up of deposits and in the depression quaternary deposits are found, belonging to the holocene (gravel and sand). In the Jiu - Motru River the deposits contain 4-6 layers of lignite, of low thickness, so the area was affected by coal extraction. From the point of view of the hydrographic network, except those of the lower order, the waters passing through the region belong to the basin of Jiu and Tismana. These wat...

Forests are import to the health of the planet, as well as an economic resource of the country. Latvia has 5th highest forest area coverage in the European Union. Major tree species in Latvia are birch, pine and spruce, with the birch having one of the highest felling rates as % of end of year stock. Importance of the topic is that as Latvia, in the particular in exports of selected timber products, as softwood sawn timber, birch plywood, chipboards and pellets, are among one of the ten largest exporters in the wo...

Bilberries selected from U.P. V. Higigel were investigated for their antioxidative potential using 2,2-dyphenyl-1-picrylhydrazyl (DPPH) scavenging. In order to determine the total content of polyphenols, the method described by Tamas-Krumpe Octavia and collaborators in 2010 [1] was chosen, consisting in the use of Folin-Ciocalteu reagent 0.2 N and sodium carbonate (Na2CO3) and the use of gallic acid in different concentrations as a standard. The spectrophotometric determination method based on the formation of the...

Forests play an important role in carbon storage and global carbon cycling. The processes of litter decomposition, movement within the soil, and incorporation into different soil layers play a crucial role in the functioning of forest ecosystems. These activities are important in regulating the cycling of soil organic matter and the storage and release of carbon into the atmosphere. Soil carbon and carbon input via litter has been well-recognized, however studied relatively less compared to other carbon pools, but...
