In 1949-1989 483 sites of Carex limosa and 315 sites of Scheuchzeria
palustris were recorded in Poland. These plants were described in 16 plant communities
of the following classes: Scheuchzerio-Caricetea fuscae, Oxycocco-Sphagnetea and
Phragmitetea. Carex limosa and Scheuchzeria palustris occur mostly in the following
communities in Poland: Caricetum limosae, Drepanoclado-Caricetum limosae, Sphagno-...
Employing a developed equation for determining the coefficient of
naturalness a valorization of 55 randomly selected mid-field depressions occurring in the
South Kujawy region was carried out to estimate the naturalness of their floras. While
investigating the dependence between the number of species and increase in areas of
"kettle lakes" it was calculated that at least 20 mid-field...
The present study contains the results of investigations the taxonomic
composition of diatoms in the water bodies of the alpine garden Arboretum in
Rogów. It is the first study devoted to the diatoms of this area.
329 species of vascular plants and 52 species of mosses were recorded
in the hydrogenic soils of the South Kujawy region. In the vegetation 78 different
communities and associations were represented. Among them 12 communities of
anthropogenic origin were distinguished. They belong to the following classes:
Bidentetea tripartiti, Plantaginetea maioris and Artemisietea.
In 1988-1990 phytoplankton was investigated in the Sulejów
Reservoir. Two developmental peaks were recorded: a spring and an autumn ones; each
of them was dominated by diatoms, which constituted 80.0 to 97.5% of total
phytoplankton abundance. In all months Siephanodiscus hantzschii Grun. was the
dominant species. The subdominants were phytoflagellates, whose intensive development
was observed...
The study contains the characterization of forest associations of the
„Dąbrowa Radziejowska" reserve prepared on the basis of phytosodological data and
a map of real vegetation. Two communities, Potentillo albae-Quercetum and
Tilio-Carpinetum, have been distinguished. Potentillo albae-Quercetum is the dominant
community and displays a differentiation into six forms.
The present study describes changes that have occured in the
phytocoenosis of Pino-Quercetum abieieiosuni in the „Jamno” reserve. It was determined
that the vegetation of this reserve, due to its high dynamics, recovers to its
natural form of Tilio-Carpinetum lypicum with Abies alba. The disapperance of Pinus
silvestris from all layers of the phytocoenosis and an essential increase in Carpinus...
The thicket communities grow in the fields in the neighbourhood of
the village of Olsztyn near the town of Częstochowa. They include 235 species of
vascular plants and 15 taxa of mosses. Two thicket associations of the class
Rhamno-Prunetea are described.
