Oxidative stress biomarkers in the blood of White Stork Ciconia ciconia chicks were analyzed during their development in nests in polluted and control environments. The control, relatively pure, environment was the village of Kłopot, with no industrial plants within a radius of 150 km. Blood samples were also collected in two polluted areas, including the suburban village of Czarnowo, located 20 km...
The aim of the presently study was to provide information about the occurrence of Dina lineata in selected reservoirs of the city of Olsztyn and its surroundings. The material was collected applying the qualitative method. The leeches were found in the overflows of Olsztyn lakes (Skanda Lake and Redykajny Lake) and small astatic midfield reservoir near Samławki.
Rapid urbanization processes are not neutral to the environment, especially amphibians. Their double-environment lifestyle makes them particularly vulnerable to negative changes in the environment. Inventory research on batrachofauna carried out in urban areas usually provides data on its current state, but there is little information about changes in its composition over the years. The aim of the...
Thelidium incavatum, Th. minutulum, Th papulare, Th. rimosulum and Th. zawackhii have been identified from the Polish lowlands. Many sites of the above species are located in industrial and urban areas of the Kujawy region. The species are illustrated and described based on the examined material. An identification key to the species and thier distribution are provided.
The paper presents the results of tracking a pack of wolves carried out between January and February 2013 in the Forest Division of Solec Kujawski in Bydgoszcz Forest, which surrounds three cities – Bydgoszcz, Toruń and Solec Kujawski, and locally encroaches on their administrative areas. The behaviour of wolves and their migration routes were determined based on tracks left on snow. The location...
The paper presents the results of the research on the composition of lichen species of larch in the towns of Podlasie. 29 species of lichenicolous fungi have been recorded. A synthesis of epiphytic lichen biota of larch in Poland has been made. Despite the homogeneity of the substrate, the lichen biota of larch in Poland according to our own data and literature amounts to 107 species, some of which...
Opinions about the insufficient realization of international strategies taken after the Rio Declaration on Environment and Development in 1992 appeared particularly in the last decade. In spite of adopted legislative acts and the years passing, the global development does not seem positive. The growth of world cities should be accomplished according to the idea of sustainable development, yet it is...
Ecosystem services originated from various ecological units, local as well as global, hierarchically, they depend on the structure and functions of the ecosystem under study and its human community. They are involved in controlling and maintaining the development of natural resources in the ecosystem, human activities and prosperity through the use of material and non-material benefits. The technology...
The paper is to present the issue of implementation of sustainable development on the example of eco-city. It highlights the complexity and multi-faceted nature of the phenomenon and notion of eco-city within its different aspects. This issue is discussed in an interdisciplinary manner and combines humanistic and scientific approaches. Hence, the authors of the above text aimed to characterise sustainable...
Variability of green biomass quantity in plant communities found in study transects established along selected traffic routes in Białystok was studied. The study was conducted in a total of four transects including three in non-forest plant communities and one in a forest community located in the vicinity of Białystok’s main outbound roads. The effect of different distance of the study fields from...
Biological activity and morphometric characteristics of entomopathogenic nematodes, Steinernema kraussei, isolated from the Świętokrzyski National Park were studied. The results have shown that S. kraussei has slower, but more efficient invasiveness than nematodes originated from the bio-pesticide. Morphometric comparative analysis did not show any significant differences between nematodes isolated...
The northern part of the Ustyurt plateau is the main area in Uzbekistan where rare and interesting species Lagochilus acutilobus occurs. The intensified exploration and production of natural gas carried out in recent years by Uzbekistan’s National holding company “Uzbekneftegaz” together with the Russian companies “Lukoil” and “Gazprom” is the main factor degrading the soil and vegetation in this...
After studying ecosystems and biosphere function for decades, Howard T. Odum sketched a methodology for calculating the value of the biophysical resources of nature and also the products of human activity. The methodology of “emergy” or “solar energy previously added” measures the biophysical work embedded in processes that use geological and biological resources and also human labor. According to...
Most studies on the effects of water quality on amphibians concern experimental conditions. The main aim of our study was to determine whether the quality of water bodies in urban environment may be a factor leading to local extinction of some amphibian species. We investigated the current amphibian richness in Kraków water bodies and the water quality of these water bodies. We compared our results...
The species composition and structure of secondary communities developed after deforestation in fertile oak-hornbeam habitats and afforestation of post-arable land from Tilio-Carpinetum and Melitti-Carpinetum circles in the Knyszyńska Forest have been studied. The analysis was based on 178 relevés made by Braun-Blanquet method, including 47 relevés of oak-hornbeam natural communities, 59 relevés of...
The path of Cladonia-Scots pine forest located on dune in Biebrza valley (NE Poland) was carefully studied in order to assess the influence of recently obsolescent selection cutting management on terrestrial lichen biota. Transect was located along the dune ridge crossing both lichen rich pine forests and other adjacent communities. Distinctive habitat patches were characterized by relevé. Within...
A total of 37 lichen species were identified during the first lichenological research conducted in 2014 on the Folusz hill, including 28 taxa of epiphytes, 10 epixylic lichens and 4 common species of epigeic lichens. Historical sources contain only data on the occurrence of 13 taxa of epigeic lichens. In total, the list of lichens occurring in this area includes 48 species. No characteristic species...
Forest roads are treeless strips of land without any natural cover, appropriately shaped in a longitudinal and transverse direction, along which traffic is possible. Road embankments and surfaces are made of proper materials, with the preservation of technological requirements and particular attention to the density of subbases in the road construction. Surface water runoff occurs on all roads as...
The dune hill in Folusz is one of the most interesting sites with xerothermic vegetation in the Polish lowland. It is different from other sites by the fact that xerothermic vegetation covers a single dune located amidst large areas of Molinia meadows rather than slopes of river valleys. Vegetation occurring on the hill represents a cold Stipa steppe with rare species of floodplain meadows and has...
The long-term forecasts predict that global warming will increase frequency and area of forest fires. Apart from economic losses resulting from a reduction of wood volume and annual increments of trees, the post-fire areas requiring the reforestation are enlarging considerably. The present study aimed at the comparison of growth parameters of Scots pine, European larch and common oak seedlings growing...
