Among the found green algae Apatococcus lobatus played important role. It occurred on the surface of nearly all examined trees creating dark green coatings on the tree barks (excluding Carpinus be lulus). On Abies and Picea apart from Apatococcus also other synantropic green alga occurred Gloeotila protogenita. They were accompanied by the following species: Chlorella vulgaris, Ch. ellipsoidea, Klebsormidium flaccidum, Stichococcus bacillaris, Pseudococcomyxa simplex and Heterothrix exilis, representing probably previous natural communities. Obtained ultrastructures of cells of Apatococcus showed inside some specimens presence of fungus haustorium, which however did not affect cellular structures of this algae. This form of symbiosis has not been observed so far in the case of this green alga. Characteristic ultrastructure observed in the green alga Gloeotila (in particular the thick layer of mucus surrounding the vegetative cells) proves presence on this area of a typical land form containing pyrenoid of a specific structure. Its land character is also proven by the reproduction ways.; W tej pracy przedstawione zostały wyniki badań dotyczące glonów aerofitycznych, występujących na różnych drzewach na terenie rezerwatu ścisłego „Mokry Bór” (Świętokrzyski Park Narodowy). Materiał został zebrany w lutym 1995 r. Stwierdzono na prawie wszystkich badanych drzewach (z wyjątkiem Carpinus betulus) obecność Apatococcus lobatus. 2000-01-01T00:00:00Z http://hdl.handle.net/11089/15874 Analiza jakościowa flory desmidii na torfowisku Lubiec w latach 1984-1995 Lesiak, Teresa In 1984-1995 the desmid flora was analysed in the Lubiec peat-bog. Of 206 taxa recorded as many as 43.2% were accessory and accidental species, which testifies to a high variability of this desmid community. The Thumark Q green algae factor was applied for defining the peat-bog’s trophic status, which decidedly determines the species composition and abundance of desmids. 2000-01-01T00:00:00Z http://hdl.handle.net/11089/15869 Okrzemki rzeki Dobrzynki w Pabianicach (Polska Środkowa) Rakowska, Barbara The Dobrzynka River is a left tributary of the 21.5 km long Ner River. Benthos samples were collected at the town of Pabianice, where the river is affected by communal-industrial sewage inflowing from a sanatorium at the village of Tuszynek, from the southern part of Pabianice and the „Pamotex” Cotton Mill. On the basis of 15 samples 97 diatom taxa were identified (Tab. I). Table II presents 5 dominant taxa (above 5%) and 9 subdominant taxa (2-5%). 18 constant species (81-100% of samples) were distinguished. Saprobity was determined for 84 species (Hofmann 1994, Lange-Bertalot 1994). On the basis of sapro-biological analysis the Dobrzynka River water at Pabianice may be characterized as α-β-mesosaprobic, which attributes the water to Water Purity Class II (Turoboyski 1979). 2000-01-01T00:00:00Z
