Porównanie zbiorowisk grzybów zasiedlających gleby powstałe na skutek odwodnienia utworów organicznych w okolicach Łap i Uhowa

Celem pracy jest poznanie i porównanie struktur ilościowych i jakościowych zbiorowisk grzybów zasiedlających mursz oraz torf wybranych gleb organicznych murszowych na torfowiskach zalewanych doliny Narwi w okolicach Łap i Uhowa.

In the study analyzed four organic-muck soils from desiccated but flooded peatlands In the Narew National Park. The sites were near Łapy (two research positions) and Uhowo (two research positions). Three of the analyzed soils belonged to the weakly mucked and one was medium mucked. The work carried out were obtained 146 fungi isolates, which were represented by 39 different species. Soils from Uhowo were characterized by a greater diversity of species and quantitative in comparison to the soils from Łapy. Qualitative structure of communities of soil fungi were different. The largest number of isolates and species was characterized by medium mucked soil. This means that increasing intensity of soil transformation favours greater diversity of fungi species in the communities growing in dehydrated peatland. The fungi are sensitive indicator of changes in the soil and the structure of these communities change with the changes in habitat conditions. The muck layers were occupited by fungi communities of much stronger diversified qualitative and quantitative structures than those found in deeper layers of peat. It should also be pay attention to Helicosporium vegetum, that occurred relatively frequently In the analyzed soils. Most probably they play an important role in transformations of organic substance of mucked hydrogenic soils.
