The moss grass Coleanthus subtilis (Tratt.) Seidl is a rare, diminutive grass which grows on wet muddy bottoms of drained water bodies displaying a high degree of water level dynamics, such as fishponds or water reservoirs.

In this study, we examine the pattern of occurrence of Impatiens parviflora in Central European oak forests over time and its ecological requirements within these types of communities. Research was based on phytosociological data collected in 3776 relevés. A modified TWINSPAN algorithm were used to distinguish the groups of oak forests. The ecological preferences of the I. parviflora and studied communities...
Obecna ochrony przyrody, aby była skuteczna, potrzebuje innych rozwiązań niż tylko aktów prawnych, np. zakazów. Kluczowym czynnikiem, który może wpłynąć na skuteczność ochrony przyrody, ważnym również z ekonomicznego punktu widzenia, jest szeroki zakres społecznej świadomości i uznania dla wartości przyrodniczych. Przykładem wykorzystania tych wartości są świadczenia ekosystemowe (ES), czyli wszelkie...

In the paper, terminology still used by Polish authors is compared with that used in current English-language publications. Some examples...
The paper presents results of geobotanical and taxonomic studies on the distribution and habitat requirements of Nymphaea candida in southern Poland.
