THE BENTHIC FAUNA OF LAKE-MIKRI-PRESPA

A brief description of the benthic macrofauna in Lake Mikri Prespa is given. The species composition and abundance were determined. Emphasis was given to the spatial and temporal distribution of the origochaete s, the most important benthic group in the lake. Four out of five olig ochaete species were endemic and the influence of some significant env ironmental variables: depth, C:N ratio, substrate type and pH, was exa mined. Indications of a potential for interspecific competition for sp ace between Psammoryctides subspecies and other benthic species were d etected.
