Lycopodiella inundata is an endangered, wetland species, able to occur in secondary, anthropogenic habitats. The article presents five-year changes in the occurrence of Lycopodiella inundata on the one of the largest stands in Central Poland. Chosen parameters of population were examined in different stages of vegetation succession. In open thickets the number of fertile stems was near three times...
The distribution of A. europaea indicates the relict character of its localities related to the Pleistocene and the Holocene evolution of vegetation. In 2011, a large population of A. europaea was discovered in central Poland. The measured plants are taller than those previously recorded in Poland and Europe, and also were the tallest of all the Asiatic and North American species. The aim of our paper...
Attempts to study biodiversity hotspots on a regional scale should combine compositional and functionalist criteria. The detection of hotspots in this study uses one ecologically similar group of high conservation value species as hotspot indicators, as well as focal habitat indicators, to detect the distribution of suitable environmental conditions. The method is assessed with reference to thermophilous...
The rehabilitation of landscapes along river valleys play an ever more important role in urban management. The first step is evaluation of natural conditions of green areas. We propose a validation method based on analysis of land use changes in the last 200 years, actual vegetation mapping, and the hemeroby concept. The field study was conducted in the Sokołówka River valley in Łódź city (Central...
Celem niniejszego artykułu jest określenie roli oczyszczalni ścieków czyli punktowych źródeł zanieczyszczeń (PZZ), zlokalizowanych w zlewni Pilicy, w zanieczyszczeniu rzeki związkami eutroficznymi i dioksynami na całej jej długości. W zlewni Pilicy wyznaczono 6 stanowisk ciągłego monitoringu jakości wód Pilicy oraz 17 różnej wielkości oczyszczalni. Wyniki analiz pokazały, iż małe oczyszczalnie ścieków...
