The paper presents results of floristic research on vascular plants in the abandoned limestone quarry in Tyniec. Altogether, 104 species representing 26 families were found. The species composition of the plant communities in the quarry was characteristic of dry grassland and meadow communities. The degree of synanthropization was 97.1%. Carlina acaulis was the only protected species found in the...
The aim of the study was to determine the degree of the enrichment of the flora of peat bogs and transition mires in anthropophytes and apophytes. The study included the flora of 87 bogs and mires in the Kashubian Lakeland and Kashubian Coastal Region. 149 species of synanthropic plants were found, most of which were found at a single site. Apophytes represented nearly half of the total number of...
In 2009 and 2010, monitoring of conservation status and future prospects of the forest communities of Quercetea robori-petraeae Br.-Bl. et R.Tx. 1943 class was conducted in the Sudetes and their foothills. 31 sites were selected. At each site, three phytosociological releves were collected. An important component of the global assessment of oak forest communities is the occurrence of synanthropic...
The paper presents the characteristics of Sudeten grasslands (species composition, floral diversity and habitat parameters) from the perspective of diversified management. On the sites examined, hay meadows were found with Arrhenatheretum elatioris, variant with Trisetum flavescens and pastures of Lolio-Cynosuretum. Mowing and grazing promoted floristic diversity. There were few grass species. On...
In 2009 and 2010, floristic research was carried at two sites in Wrocław, Poland. The first site was along 3.5 km stretch of the newly built city ring road between Bielany and Oporów. The second site was along a newly built road near the post office in Oporów. The aim of the study was to determine whether spatial and technical urbanization in the area has favored the development of a variety of segetal...
This study is part of a long term, multi-faceted research project on rates and directions of spontaneous vegetation dynamics after cessation of agricultural land use, and on the effects of anthropogenic modifications of this process by managed mowing or plowing. The results are based on data from a permanent plot established in Wielkopolski National Park in 1976. This article presents share spectra...
Floristic and ecological data was collected three times (in 2000, 2006 and 2011) in fifteen urban parks in Wrocław. Results were compared to determine whether bryophytes can survive in urban environments, or whether they die off because of the constant pressure of urbanization. Other questions examined include whether bryophytes remain in the same habitats, or whether they change their spatial distribution;...
Various types of artificial habitats are associated with the modified landscapes. Among them are abandoned sand and gravel pits. These sites have a varied terrain. The presence of slopes, elevations, depressions and ponds creates favorable conditions for the colonization and development of species from very different habitats. Exploitation of raw materials and the accompanying infrastructure lead...
The conservation status of the communities of the class Asplenietea trichomanis was studied in 2010 in southern Poland. In all, 81 sites with rocky plant communities were selected, and 270 phytosociological relevés were collected. Alien species were found at 27% of the sites. This indicates that the rocky communities there are exposed to strong pressure of plant invasion. The most common alien species...
The Neotropical species of Rhopobota are listed; nine species (R. larocana sp. .n., R. mostardana sp. n., R. mayarica sp. n., R. ventriloba sp. n., R. monospina sp. n., R. granpiedrae sp. n., R. lacteicaput sp. n., R.cornifera sp. n., R. platyceria sp. n.) are newly described from Cuba and Brazil. Distribution of the genus is mentioned.
Based on an extensive survey of museum and private collections, distributional records of the Tetratomidae and Melandryidae in Poland are verified and updated. Collection data of nearly 2000 voucher specimens belonging to 35 species are listed. Two taxa are reported as new in Poland: Orchesia grandicollis and Dircaea australis. Due to unclear diagnoses, two species belonging to the genus Zilora were...
In 2009, I conducted an Odonata inventarisation in 6 areas of the Narew National Park, which resulted in the documentation of 23 species. Besides that, I also analysed all the inventarisation works which were done in the Park area, a total of 44 species were until now documented.
