The paper presents the results of studies on bryophyte flora of the Reberce forest reserve located in the Przemyśl foothills. Thirty-three species of liverworts, 70 species and two varieties of mosses were found. Terrestrial (66 species) and epixylic (58) bryophytes formed the largest ecological groups in the reserve. Twenty-four protected species were also recorded, eight endangered bryophytes and...
The Rubus flora of northern Wielkopolska (Greater Poland) is not yet fully discovered, but the recent studies on the genus Rubus suggest that it is clearly not as rich as in case of southern Wielkopolska. The results of the field observations show that the area of the Durowo Forest District contains 14 representatives of the genus Rubus, out of which the presence of four taxa has already been reported...
The article is a first update of the list of liverwort localities published in A synopsis of liverworts occurring in the Tatra Mountains (Western Carpathians, Poland and Slovakia): checklist, distribution, and new data (Górsk i & Váňa 2014). It presents localities of 19 liverwort species collected during 2003–2014 in snowbeds in the entire area of the Tatra Mts. Moreover, for some species, localities...
This paper provides a floristic list of 111 vascular plant species recorded in the Polish part of the Lithuanian Lakeland in 2012–2014, using the ATPOL cartogram method. There are 36 native species, 53 established alien species, and 22 casual alien species. Among the established alien species there are 13 species native to Poland which have no natural geographical range in the Polish part of the Lithuanian...
This paper describes, illustrates, and maps a new regional bramble species occurring in the Myśliborskie Lake District in NW Poland. It represents the series Mucronati, which until now has never been recorded in this part of Europe. Locally it is the common plant and usually can be found in pine plantation established on former farmland.
The aim of this study was to characterise the flora and plant communities in the Moryńskie Hills, Poland. A total of 45 transects and 23 phytosociological relevés were established. Plant communities were identified based on the description of the test patch of the vegetation cover. The paper presents floristic analyses of vascular plants, which includes the taxonomic affiliation of species, their...
Strong and long-lasting human activity in most European lowland river valleys results in narrowing the area of inudated ecosystems from wide floodplains to the space between embankments. This concerns especially regulation and drainage works, as well as hydrotechnical infrastructure construciton. The Warta Mouth National Park is a suitable region for inudated habitats research – over 5000 hectars...
A good knowledge of species delimitation is crucial for the biodiversity protection and the conservation of wild species. We studied the efficiency of AFLP markers and morphological characters to assist species determination for Melica ciliata L. and M. transsilvanica Schur within European range of distribution, including isolated and range-limit populations of "M. ciliata" (i.e. M. cf....
The paper presents ten new localities of Orobanche pallidiflora Wimm. & Grab. from Poland (Middle Roztocze, Równina Bełska plain, Wyżyna Malopolska upland, Góry Kaczawskie Mts and Western Bieszczady Mts). Information on hosts, abundance and habitat preferences at the new localities is given and a supplemented map of the distribution in Poland is included.
The research was carried out in north-eastern Poland in the vicinity of the village of Haćki (52°50’00’’N; 23°11’20’’E). This area is distinguished by an exceptionally numerous agglomeration of kames (10). Previous archaeological and soil research showed that kames have been inhabited by man from the iron age, and that the following stages of colonization are reflected in three levels of fossil soils...
A study of the very complex, from the taxonomic point of view, Taraxacum genus was undertaken in the area between the towns of Cieszyn and Bielsko-Biała (S Poland). Taraxacum species belonging to three sections: sect. Hamata H. Øllg. (three species), sect. Palustria (H. Lindb.) Dahlst. (one unidentified taxon), and sect. Ruderalia Kirschner, H. Øllg. et Štěpánek (61 species) were recorded. Nine species...
Hybrid speciation within the genus Elymus is analyzed and discussed. The supposed hybrid origin of Elymus x mucronatus between Elymus repens and Elymus hispidus was tested. In this aim, pollen viability and AFLP variation of putative progenitors and progenies from two natural populations were studied. Pollen fertility of hybrids ranging from 0 to 91.95% (average 59.50%) indicates the occurrence of...
