Extract

In present day ecology, competition is a subject typically generating controversies that pervade the whole field. Ecology is concerned with relations between organisms and their environment. As the environment of any organism has biotic besides physical components, relations between organisms are obviously important. Competition is one of them. According to many ecologists it crucially affects the fate of populations and species. Precisely this assumption has led to vigorous debates (cf. Lewin 1984).

I intend to show that elementary methodological analysis could easily dissolve the controversy. Methodology, indeed, has not always been brought to bear on biology as it should. This point is elaborated at the end of the paper.

Ecologists use a variety of descriptive units, beside individual organisms. Here the population - a group of individual organisms of the same species and the community - a group of populations are of special importance.
