Abstract

Species from Aphanomyces genus were investigated in 225 limnologically and trophically different water bodies (springs, rivers, ponds and lakes) as well as in humid soils of north- eastern Poland. Distribution of particular species and their role in diverse ecosystems has been investigated. Thirty taxa, including: 2 species of cultivated parasitic plants, 3 species of parasitic animals, 6 saprotrophic species and 5 species of saprotrophic/ opportunistic species were recorded. Some of Aphanomyces species occurred also as parasites of algae, straminipiles and invertebrates. Among parasitic species: A. cochlioides, A. euteiches (cultivated plant parasite), A. astaci (crayfish parasite), A. piscicida (fish parasite) playing economically important role were found. Amino acid, carbohydrate and urease assimilation tests were used.

Key words: Aphanomyces species, ecological diversity, hydrochemistry, parasite, economical importance.
