“…The advantages of using artificial substrates for collecting algae in saprobiological research have already been stressed before (Shideckova 1962;Klapwijk 1978Klapwijk , 1980. The need to revise and develop the saprobity system for stagnant ditches and other stagnant waters in the Netherlands is obvious, as has been stated before (Klapwijk 1978(Klapwijk , 1980. A covering of the water surface with duckweed and floating algae was associated in this study with low benthic algal biomass and low NHt concentrations.…”

“…Spearman's rank correlation coefficients between some chemical parameters 355 mg 1-1; June 309 mg 1-1; July: 340 mg 1-1), due to evaporation and the inlet of relatively brackish boezemwater to maintain the water level in the ditches. Klapwijk 1980). The present investigation, however, also brought some drawbacks of the method to light, particularly the influence on the results of floating algal masses and duckweed, which interfere with the benthic algal flora in two possible ways: (1) by light interception and (2) by utilization of the nutrients in the water.…”

“…Benthic algae were sampled with glass microscope slides as artificial substrates, fixed in Plexi- glas racks, which were suspended from floats in the water, as described by Klapwijk (1980). The slides were exposed in the ditches for a period of 2 weeks all in the same direction (southwest).…”

A hydrobiological study was carried out to elaborate the water quality classification system of CASPERS t KARBE (1966KARBE ( , 1967 for the larger stagnant bodies of water in the western part of the n'etherlands. Significant correlations have been established between different physical and chemical parameters and phytoplankton community structures such as diversity and saprobity. From this a proposill is developed t o quantify the water quality classes in CASPERS t KARBE'S scheme on parameters measuring the bioactivity, oxygen regime and phytoplankton community structure. The scheme is now incorporated in the practical water quality assessment in North-and SouthHolland both for routine monitoring as well as for special water quality studies.

Epilithon, epiphyton, epipelon, epipsammon and plocon diatom samples and water chemistry samples were collected bimonthly from 11 stations along the Mesta River, Bulgaria between December 1989 and April 1991. Principal component analysis (PCA), correlation, and dominance analysis were employed for describing the seasonal dynamics of diatom assemblages and estimating the correlation between diatom distribution and the physico‐chemical parameters. All periphytic communities were compared by PCA, MANOVA and Fisher's LSD multiple comparison test. Ionic strength and eutrophication were the major abiotic factors affecting diatom distribution in the epilithon, epiphyton, epipelon and epipsammon. Current velocity had an important influence on the diatom assemblages from the epilithon and epiphyton. Epilithon showed the lowest correlation with most of the environmental factors and had significantly lower species diversity than epiphyton, epipelon and epipsammon. Multivariate analysis of the diatom data suggested that in all benthic habitats of the Mesta River seasonal replacement of diatom assemblages was controlled by the water chemistry rather than substratum, current velocity or discharge. The oligotrophic, mesotrophic and eutrophic diatom communities in the Mesta River comprised early‐, mid‐ and late‐successional colonizers respectively. Multiple comparisons of all periphytic communities showed that habitat specificity was positively correlated with current velocity.
