Species and trophic composition of nematode communities, their abundance and spatial distribution of the sediment/soil interface in the Lower Prut (near village Chislita-Prut) were studied. The nematode abundance strongly varied 39.6 – 570.0 ind. thousands m-2. Fifty one species belonging to 42 genera, 27 families and 8 orders were identified. Families Dorylaimidae, Cephalobidae, Tylenchidae and Telotylenchidae are represented by more species and occupied almost the entire sampling area. Higher species diversity of nematodes was noted in the terrestrial than in aquatic samples. A third of the species found in aquatic area belong to taxa, which apparently developed and radiated under terrestrial conditions. Three species were the most frequent and abundant in deep water – Brevitobrilus stefanskii, Panagrolaimus hygrophilus and Bursilla monhystera. The species Tripyla glomerans, Diplogaster rivalis and Chronogaster typicus are the typical species for freshwater conditions, however their populations were not numerous in deep water. The species from the families Discolaimidae, Leptonchidae, Diploscapteridae, Anguinidae, Hoplolaimoidae, Pratylenchidae, Paratylenchidae were found only in the terrestrial area. Bacterial feeders were the most numerous in the sampling area. Ecological indexes such as species diversity (Shannon-Weaver), species richness (Margalef) and Maturity index (Bongers) were high in the case of nematode communities from the terrestrial habitats. |
