Opis:
Results of pollen analysis and records of fossil plankton organisms indicate human activity in catchment areas of lakes. These records of human impact depend on the form of anthropogenic activity, scale of settlement processes and location of the zones of activity. Comparison of the two records, which illustrate transformations of terrestrial and limnic habitats, may indicate the zones of human activity. Some examples of correlation of palynological human impact indicators and Pediastrum from lakes in Wielkopolska have been discussed.

Opis:
An information technology for calculation of carbon sink in stemwood of forest ecosystems on a territorial basis is developed. This information technology involves interpretation of input data of statistical inventory of forest stands using electronic maps of forestry, formation of databases and processing the data by applying a special algorithm for calculating the carbon sink in stemwood and presenting the results in a form of thematic maps. The estimation of the carbon sink in stemwood is done by using a "bottom-up" (wood – sample plots (SP) - forestry) approach applying mathematical models of distributed inventory of the carbon sink that take into account regional specificities of species in the study area and average annual growth of biomass. We estimated carbon sink in stemwood using data from experimental studies conducted on 54 sample plots of forestry “Spaske” of forest enterprise "Broshnivske FE" of Ivano- Frankivsk region. The largest carbon sink occurs in mixed forest ecosystems - 1829 tons/year, the average carbon sink (per ha) is 951 kg/year. The information technology can be applied for estimation of the carbon sink in forest stemwood in any part of Ukraine or another country where necessary input data are available.

Groundwater Dependent Ecosystems (GDE) are important elements of biodiversity and providers of valuable goods and services to society. Preservation of their environmental functions in the face of increasing anthropogenic pressures on groundwater resources and progressive climate change depends on appropriate environmental policies and water resources management. A brief overview of current knowledge of the functioning of GDE and their relations with groundwater is given in the first part of the article. Effective incorporation of GDE into the policy and practice of water resources management depends on thorough understanding of how hydrogeological processes and human impacts influence the quantity and quality of groundwater available to ecosystems. Major scientific challenges in this regard are related to adequate representation of GDE in the conceptual and re lated numeri cal models of groundwater systems. An example of a GDE (Wielkie Błoto fen in southern Poland) is discussed in some detail in the second part of the article. It illustrates some of the pressures and threats which GDE located in densely populated regions of the European continent are experiencing nowadays. Selected research tools used to quantify those pressures and threats are described and discussed.

Opis:
Results of the analysis proved that the net primary productivity has a strong connection with the solar insolation. The length of daylight and the level of solar radiation are the driving forces behind changes in growth of primary products, as floral forms are among the first indicators of changes in ecosystems due to global warming. The group of climatic components that have a moderate connection with the bioproductivity of ecosystems of the Polissya are derivatives of bioclimatic indicators related to air temperature, including annual temperature, seasonality, minimum temperature of the coldest month, and the average temperature of the coldest quarter. Seasonality and the annual variation of temperature affect bioproductive processes inversely: the productivity decreases with the increased temperature range between the warmest and the coldest periods of the year and in the middle of quarters.

Opis:
On 19th April, the largest wildfire of the entire history of Biebrza National Park broke out and consumed 5526 ha, mostly overdried grassland with sedges and reeds of Biebrza marshes. The very rapid spread of the fire in the open space, with the blowing wind changing directions and the inaccessibility of the area for fire-fighting vehicles were the main reasons of this third largest wildfire in Poland, after the tragic forest fires in Kuźnia Raciborska (9060 ha burnt) and Potrzebowice (5600 ha burnt) in the memorable year of 1992. After this event, activities were undertaken to develop a fire protection plan for the Biebrza National Park. It took into account an innovative approach during the analysis of the existing fire risk, primarily regarding the non-forest terrestrial ecosystems composed of herbaceous vegetation, which constitutes as much as 61.2% of the park’s area, and to propose protection methods adequate to the threat. The work was completed in the framework of the project entitled ‘Development of the method for assessing the fire risk of non-forest ecosystems and the principles of fire protection for the Biebrza National Park – stage I,’ commissioned for the Forest Research Institute by the Biebrza National Park, financed by the State Forests from the forest fund, in accordance with the contract EZ.0290.1.24.2020. The article presents a preliminary method of classifying the fire risk of non-forest ecosystems, considering the occurrence of the fires in the Biebrza National Park in the years 2007–2020 and the type of vegetation burnt. This method, after supplementary field tests planned in 2021, will enable evaluation of the fire risk, which shall be a premise for the development of a fire protection plan.

Opis:
The qualitative and quantitative descriptive models of tree architecture differ in the degree of complexity and the way of mapping tree structure, and thus, are of varied use in forestry. The qualitative, Hallé−Oldeman models, serve as a framework for analyzing tree architecture and help define the different components of a tree branching system. Among the quantitative models (here: horizontal, three−dimensional or vertical ones) the horizontal representations are the most parsimonious, and proved to be useful for examining the effects of competition process and the light conditions within the forest understory. The three−dimensional representations (Quantitative Structural Models; QSMs) have the widest range of applications as they may be used for deriving both the two−dimensional traits (such as crown length or branch height) and the volumetric traits (such as tree crown volume or wood volume). At the same time they are the most complex ones. The vertical models were used to study the impact of local terrain shape and wind conditions on tree architecture, but the way of deriving such models from the QSMs seems excessively laborious. However, we highlight here also a photogrammetric method, which allows to obtain an analogous model in much simpler way. Both three−dimensional and vertical representations are useful for determining the wood quality features. Three−dimensional models can be used to accurately measure tree woody biomass, while horizontal models can be used for reliable biomass estimations.

The scope of this paper is to conceptualise a data-based research framework for the role of creative networks in cultural exchange. Participation in culture measured as audience per 1000 residents and expenditures on culture-related activities were analysed in relation to such territorial assets as accessibility to creative infrastructure, the economic status of residents, the governance networks of civil society, and cultural capital. The results indicate how accessibility, governance networks, and cultural capital contribute to participation measured via audience indicators while a low poverty rate has explanatory value with respect to expenditures on culture.

Opis:
Fusarium is a large fungal genus, but scientists who work with it continue to search for new species to help bridge perceived phylogenetic gaps and to assess the biogeography of species origin and distribution.  Potential new sources for species include collections made from plants and soil in native ecosystems and  ubsistence agriculture farms. These ecosystems are less likely to have suffered anthropomorphic changes and  may offer the best hope for identifying previously undescribed species and for obtaining reliable data on species distribution. In addition to new collections, new species also may result from the break-up of a number of  large species complexes that are held together primarily by   orphological similarities. The two approaches  are complementary and should collectively help to increase the number, diversity and quality of the species  known within the genus.

Opis:
The presented study considers the impact of public expenditure related to land development on the potential of an urban green infrastructure to provide ecosystem services (ES). The study site (Szachty) is located in Poznań, the fifth largest city in Poland. In the article, we recognised the type of expenditure (permanent infrastructure and ongoing maintenance), the costs and the influence on ES (stimulating, weakening or no relevant). The study shows that the financial policy concerning the study area is focused on creating an infrastructure that enhances cultural ecosystem services (CES). However, the creation of recreational facilities weakens the potential of the area for supplying regulating services concerning maintaining nursery populations and habitats. The results highlight the need for scientific support for policymakers in understanding the synergies and trade-offs between ES, resulting from financial decisions. This is particularly important in the decision-making process in the areas of high natural value, in which full, long-term effects of the decisions may be barely visible and incomprehensible for the society. Showing the impact of financial decisions on the structure and level of ES may provide arguments supporting a more complex and high-quality social dialogue, including balancing the interests of various stakeholders.

The concept of ecosystems services has become an important model for linking the functions of ecosystems to human welfare. The aim of this paper is to identify ecosystem services generated by green areas within the urban area, classify and value them. "Ecosystem services" refers to components of nature, directly enjoyed, consumed, or used to yield human well-being (Boyd, Banzhaf 2007). This definition advances the ability to use ecosystem services as a practical measurement tool.

Opis:
Ecosystem services are an important framework for linking ecological infrastructure to urban social infrastructure, which can benefit people and ecosystems. Designing, planning and managing of complex urban systems for health and wellbeing requires urban ecosystems that are both immune to systemic changes and managed sustainably. Literature review reveals that so far only several researchers have focused on urban ecosystem services (UES). The paper aims at assessing the importance of ecosystem services at the local level with an emphasis on urbanized areas. The basic conditions and barriers to the implementation of the concept of ecosystem services in the EU policy and local development have also been identified. The paper also presents solutions concerning the creation of integrated systems of providing such services by local governments and their monitoring.

The article presents a methodology for assessing the environmental reliability of consortium ecotones of protective type on the roads of the Lviv railway. It was established that the spatial or morphological structure reflects the compound, structural relations and spatial arrangement of structural elements or ecosystem blocks, which determine the peculiarities of its functioning under certain environmental conditions. The task of the functional structure is to reflect the features of the work (functioning) of the structural components of the ecosystem. It characterizes the pace, amount and effects of substance-energy exchange, stability, performance and other important functions. The totality of the design of protective forest plantations on the railway line operates as a single system or forest-melioration complex — a consortium that performs the functions of an ecological framework, where elements and subsystems interact, providing a synergistic effect. The spatial structure of the consortium ecotones of the protective type of the Lviv railway was constructed. The analysis of the structure of consortium ecotones of the protective type and the indicators of ecological reliability are determined.

Zrównoważone wykorzystanie zasobów wymaga oszacowania ich dostępności oraz ochrony ekosystemów. Istotne jest utrzymanie zdolności środowiska do pochłaniania zanieczyszczeń i zachowanie różnorodności biologicznej. Koncepcja gospodarki cyrkulacyjnej, w szerokim ujęciu, obejmuje nie tylko zagadnienia efektywności produkcji i eliminacji powstawania odpadów lecz całokształt usług ekosystemów. Zmniejszenie ilości wykorzystanych zasobów oraz zanieczyszczeń niesie za sobą poprawę jakości życia jak również i ekonomikę przedsięwzięć.

Opis:
The Early Jurassic succession of the Holy Cross Mountains region in Poland offers a rare opportunity to study ecosystem complexity during the evolution and diversification of early dinosaurs, especially herbivorous ones. The section consists of continental and coastal deposits containing fossil assemblages spanning nearly 25 My of changes in terrestrial plants and some groups of invertebrates and tetrapods. Based on macrofossils and pollen and spores, the broader characteristics of the flora in this succession are presented. The floral assemblages show typical Early Jurassic characteristics and contain lycopsids, sphenopsids, ferns, cycadaleans, bennettitaleans, gnetaleans and ginkgoaleans, as well as conifers, and are similar to other Hettangian–Toarcian floral successions in Europe, showing the presence of a vast coniferous forest dominated by Hirmeriella in the early Hettangian, replaced by ginkgophyte-dominated floras in younger stages and araucarian conifer-dominated forests in the late Pliensbachian. Dinosaurs are documented mainly from their trace fossils (tracks and coprolites). Six distinct track assemblages (stratigraphically separated ichnoassemblages) of different ages can be identified. Current evidence indicates that while Anomoepus tracks are abundant throughout the long Hettangian–late Pliensbachian interval, medium-sized to large ornithischian tracks do not occur below the lower–middle Hettangian transition zone, associated with the first major marine transgression in the region. Hettangian strata with different theropod tracks (Grallator, Anchisauripus, Eubrontes, Kayentapus, cf. Megalosauripus), small Anomoepus tracks, numerous medium-sized Anomoepus-like tracks, Moyenisauropus tracks, tetradactyl tracks of sauropodomorphs (cf. Pseudotetrasauropus) and oval-shaped tracks of sauropods (Parabrontopodus) significantly contrast with the higher part of the Lower Jurassic succession (upper Pliensbachian Drzewica Formation and middle–upper Toarcian Borucice Formation) containing new types of medium-sized to large theropod tracks (Therangospodus), small and medium-sized bird-like tridactyl tracks (cf. Trisauropodiscus, cf. Anomoepus), exceptionally large, oval-shaped sauropod tracks (Sauropoda indet.), and new types of medium-sized and large ornithischian tracks (cf. Deltapodus, cf. Anomoepus). This points to a noticeable difference between the Hettangian and late Pliensbachian–Toarcian dinosaur ichnofaunas and may facilitate the study of regional and global changes and correlations. Both the palaeofloras and dinosaur trace fossils document ecosystem diversity and ecosystem changes, presented here in review form. The nature of these changes requires more detailed study, but preliminary results suggest the occurrence of rather complex and pronounced transformations in the dinosaur communities of the Holy Cross Mountains region. Based on our observations, the most significant event in Early Jurassic ecosystems took place within the Hettangian (change in floristic composition, the emergence of new groups of dinosaurs), but we also found what we believe to be a record of a major faunal turnover across the late Pliensbachian–middle–late Toarcian interval.
