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...
