Abstract During geobotanical studies in the north-eastern border of hemi-boreal zone, in Valday (NW Russia), rare eutrophic deciduous forests dominated by oak Quercus robur were observed. A comparison of these forests with the model of European deciduous forest in Białowieża National Park (NE-Poland) indicates a great similarity. Therefore, eutrophic deciduous forests in Valday can be classified to the Querco-Fagetea class, the Fagetalia sylvaticae order and to the Capinion betuli alliance, despite the absence of hornbeam Carpinus betulus in the region. Rarity of eutrophic deciduous forests in Valday region results probably from strong anthropogenic pressure in the past.

AbstractThe Białowieża Forest (BF) is one of the best-preserved lowland deciduous and mixed forest complexes in Europe, rich in diverse fungi. This paper summarizes what is known about the poroid fungi of the Polish part of the Białowieża Forest, based on literature data, a re-examination of herbarium materials, and the authors’ studies from 1990–2014. An annotated catalogue of polypores recorded in the forest is presented, including 80 genera with 210 species. All literature and herbarium records are enumerated, and 160 species are illustrated with color pictures. Fourteen species previously reported in the literature have uncertain status because they lack voucher specimens and were not confirmed in recent field studies. Antrodiella subradula (Pilát) Niemelä & Miettinen, previously known from Asia, is reported for the first time from Europe. Fourteen species are newly reported from the Białowieża Forest (mainly from Białowieża National Park), including 8 species with first records in Poland (Antrodia hyalina Spirin, Miettinen & Kotir., Antrodia infirma Renvall & Niemelä, Antrodiella subradula, Junghuhnia fimbriatella (Peck) Ryvarden, Postia folliculocystidiata (Kotl. & Vampola) Niemelä & Vampola, Postia minusculoides (Pilát ex Pilát) Boulet, Skeletocutis chrysella Niemelä, Skeletocutis papyracea A. David), and 6 species reported previously from other localities in Poland [Antrodiella faginea Vampola & Pouzar, Dichomitus campestris (Quél.) Domański & Orlicz, Loweomyces fractipes (Berk. & M. A. Curtis) Jülich, Oxyporus latemarginatus (Durieu & Mont.) Donk, Perenniporia narymica (Pilát) Pouzar, Phellinus nigricans (Fr.) P. Karst.]. Several very rare European polypores already reported from the Białowieża Forest in the 20th century, such as Antrodia albobrunnea (Romell) Ryvarden, Antrodiella foliaceodentata (Nikol.) Gilb. & Ryvarden, Buglossoporus pulvinus (Pers.) Donk, Dichomitus albidofuscus (Domański) Domański and Gelatoporia subvermispora (Pilát) Niemelä, were found at new localities, confirming their continuous occurrence in this forest.

The deficiency of pollinators is indicated as the main factor limiting fruit set in orchids. Nectariferous species are more successful in setting fruits than nectarless species. In the present study, we tested whether pollinator limitation lowers reproductive success in populations of <em>Cypripedium calceolus</em> on environmental islands in the Biebrza National Park, NE Poland. Moreover, we analyzed how population size and structure affect pollination success. Our observations and results of experiments document the low level of fruiting in populations of nectarless <em>C. calceolus</em> (9.2% on average) and strong pollen limitation. Generally, we noted a positive relationship between pollination success and all parameters of population size (measured by both occupied area and number of clumps or shoots) and parameters measuring floral display (number of flowers in population, number of flowers in clumps, spatial structure of flowering shoots). We suggest that information about factors influencing the reproductive success of this endangered species may be useful for planning appropriate conservation actions.

Mycosociological observations were carried out between 1994-1996 on permanent plots within a <i>Tilio-Carpinetum</i> association in the Białowieża National Park. The project was carried out with international cooperation within the "Mycological monitoring in European oak forests" programme which was a result of multiple signals concerning the disappearance of oaks in our continent. Almost 40 years before mycosociological research in the same plant association and at the same plots were carried out. Studies were mainly concerned with analysing the terrestrial macromycetes, predominantly <i>Boletales</i> and <i>Agaricales</i>. They analysed the occurrence of saprotrophic and mycorrhizal fungi. Totaly 215 species from the above listed ecological groups, but there were only 34 species common to both studies. Dominating species within the mycorrhizal group were found.
