Opis:
The size and reproduction ability of the three field populations of Carex secalina Willd. ex Wahlenb. have been assessed. In the parallel garden study selected traits from the life history of the species have been studied, such as age at first reproduction, fertility, the size of seeds, their germination ability and size of seedlings. The populations of C. secalina discovered in Poland in 2000 are characterised by small abundance and small area. All individuals from the three populations in the garden produced generative shoots in the third year of life. Statistically significant differences between the populations were found in the production of shoots with unisexual spikes and bisexual ones, the latter had not been reported in the hitherto literature on the species. The seeds started germinating after a 6-months rest. The first seedlings were observed in the first decade of May. The largest seedlings were noted in the population producing the smallest seeds. The results contribute to explaining the renewal of the populations of this species in the field.

Opis:
The diversity of ectomycorrhizal fungi and sporocarps abundance were investigated in 2003-2005 at nine permanent study plots in a 50-year-old pine forest. Diversity of ectomycorrhizal fungi consist of 53 taxa and the majority of them belonged to the genera Cortinarius, Russula, Amanita and Tricholoma. The most frequent species, whose fruit bodies were found in each study plot, were C. cibarius, L. necator L. rufus, P. involutus, R. aeruginea, T. saponaceumand the most abundant species which made the main part of total sporocarp yield were C. cibarius and P. involutus. The lowest species richness of ectomycorrhizal fungi was in study plots with the densest cover of grasses. Maximum of species over the fruiting period was characteristic for October and for September. It was noticed that some species virtually never occurred together at the same plot (e.g. C. cibarius and H. aurantiaca), meanwhile others occurred together quite frequently (e.g. H. aurantiacaand X. badius).
