This paper discusses details of the locality of Fistulina hepatica recorded on Castanea sativa, a new host species in Poland. Since 2014, F. hepatica has been featured on the list of species under partial protection, and has been marked as “R” (rare species) on the “Red list of the macrofungi in Poland”. A new locality of F. hepatica has been found in Warsaw, in the Mokotów neighborhood, on the premises of the Central Clinical Hospital of Ministry of the Interior and Administration. Two basidiomata of F. hepatica were discovered at the base of a declining sweet chestnut tree.
Accumulation of selfish DNA in cells has fundamental consequences for organism metabolism. Detrimental effects of large genome size have been demonstrated for several aspects of performance in plant and animal species. Here we check if a large genome affects occupancy among Coccinelidae and Chrysomelidae occurring in Poland. It was possible to match literature data on distribution and genome-size data for 19 species of chrysomelids and 10 species of coccinelids of different rarity (occurrence expressed as % of Poland area) and body size. There was a marginally significant (P = 0.04) and expected excess of species with large genomes among rare species (<0.73% of area), as well as an excess of species with small genomes among common species (>0.89% of area) However overall correlation was not significant (P = 0.13). Body size was not related to rarity in these species. The detection of this weak signal provides a clue to the important idea that large-scale patterns may stem from differences observed at the cellular level.

The long−term changes of vegetation cover at the level of woodland community taking place between 1959 and 2016 on the permanent study plot located in the compartment 319 of Białowieża National Park are discussed. In 1959 two distinctive woodland community types occurring on sample plot were distinguished: subboreal mixed pine−oak forest (Serratulo−Pinetum) and hornbeam−lime forest (Tilio−Carpinetum). The phytosociological investigations, carried out almost 60 years later, revealed that in case of both communities, significant, directional changes of their floristic composition took place. Particularly high rate of change occurred in case of the phytocoenosis representing the Serratulo−Pinetum community. In 1959 it contained a full set of characteristic plant species. During the study period, this community type representing the Vaccinio−Piceetea class, was replaced by the initial form of lime−hornbeam forest belonging to the Querco−Fagetea class. Also, in case of the previous Tilio−Carpinetum association, the significant changes in the floristic composition occurred, although not as large as in case of Serratulo−Pinetum community. 60 years ago this community type contained several plant species typical for thermophilous oak forests. Nowadays, it represents a typical form of lime−hornbeam association. The changes in both community types were mainly related to the strong expansion of lime and hornbeam, which took place during the study period and involved the whole study plot. As a result, the vegetation occurring on the study plot is much more homogenous now than it was ca. 60 years ago. The maintenance of Serratulo−Pinetum phytocoenoses distinguished by a high floristic diversity calls for active protective measures in all cases where such measures are allowed and where this community type can potentially develop.
