Abstract:

The article deals with the ecological classification of nematodes living in soil and in plants. A review is given of ecological classification based on the views of diffferent authors.The authors aim was to base classification of soil and plant nematodes primarily on trophic relations and to treat all other characters of the group distingushed, even those of an ecological nature, as of secondary importance from this aspect. If therefore the kind of food consumed is to be accepted as a criterion for classification then the following trophic groups can be distinguished: I - microbivorous, II - fungivorous, III - parasites of higher plants, IV -omnivorous and V - predators.The author considers this division as the most suitable for studies aimed at ascertaining the connections between the trophic levels of dififerent ecosystems, and consequently also for studies on the flow of energy through the ecosystem. It must, however, be remembered that this division involves a considerable degree of simplification. The systematic appurtenance of each of the trophic groups is given, indicating difficulties in classifying of the systematic units. The phenomenon of mycophagism connected with the facultative way of life of some Tylenchida, is dealt with in slightly greater detail. Omnivorous nematodes, obtaining their food from different trophic levels. also present a difficult problem in ecological classification. When our knowledge of the different species of this group is extended and the natural situation determining the kind of food they consume known, the matter will become far more simple, and this will permit of far more exact differentiation of his group from the trophic aspect. Mention is also made of the act that the role of nematodes as consumers has an additional aspect, namely the pathogenic activity of pathogenes and the indirect influence of many species of nematodes (from different trophic groups) on occurence of plant diseases.
