He made a cluster analysis of the choriotope types classified by substrates (grain size, type and structure of organic sediments and macrophytes as substrates for macro- zoobenthos). Lotic choriocoenoses showed greater regional differences than lenitic ones. In flat- land brooks with low current velocity there was found a higher number of species and individuals than in the lotic stretches.

Unpolluted brooks clearly indicated current and substrate-dependent structural differences in the species composition. Consequently, different “basic saprobic levels” were defined for these various brook types. In the absence of the effects of sewage the partial saprobic valencies shifted from xenosaprobic to beta-mesosaprobic range from high-mount,ain to flatland brooks. The average saprobic index showed a.n about one degree lower value in high mountain brooks than in flatland ones. The author concluded that in int.erpret.ing a,nd judging the pojlution of running waters t’he im- portance of the respective brook type and its specific basic saprobic level must be stressed. A table of the indicat,ors found in the areas under invest,igation comprised the saprohic valency, indicative weight of species, individual saprobic index and, as it new achievement, it rrniark about the geo-/phytophilous series as follows: 1) lotic: large to medium-sized stones, epilithic moss and algae in very fast to fast currents; 2) lotic: medium-sized to small stones, coarsc gravel, floating macrophytes in high to moderate current velocities; 3) lenitic: fine gravel, sand and coarse detritus, branches and leaves in moderate t,o lorn current velocitics; 4) lenitic: fine det,ritus, sand, silt, marginal ;Iqiia.tir vegetation in low to very low current velocities.
