Distribution and seasonality of desmids in the Maarsseveen Lakes area

Distribution and seasonality of desmids in the Maarsseveen Lakes area The desmid flora of mesotrophic Lake Maarsseveen I, eutrophic Lake Maarsseveen II, as well as the interconnecting broads was studied during the period 1987–1991. Seasonal perodicity of euplanktonicStaurastrum andCosmarium species in the two Maarsseveen lakes fitted the well-known general pattern of desmid abundance peaks in (late) summer time. The deviating seasonality of two euplanktonicClosterium species (C. aciculare andC. acutum var.variabile) could be related to special nutritional demands. The tychoplanktonic desmid flora encountered in the interconnecting system of peat pits and canals proved to be more diversified as the influence of nutrient-poor seepage on the habitat (appearing from conductivity, transparency and the occurrence of particular macrophyte species) was greater.

Abstract

The desmid flora of mesotrophic Lake Maarsseveen I, eutrophic Lake Maarsseveen II, as well as the interconnecting broads was studied during the period 1987–1991. Seasonal perodicity of euplanktonicStaurastrum andCosmarium species in the two Maarsseveen lakes fitted the well-known general pattern of desmid abundance peaks in (late) summer time. The deviating seasonality of two euplanktonicClosterium species (C. aciculare andC. acutum var.variabile) could be related to special nutritional demands. The tychoplanktonic desmid flora encountered in the interconnecting system of peat pits and canals proved to be more diversified as the influence of nutrient-poor seepage on the habitat (appearing from conductivity, transparency and the occurrence of particular macrophyte species) was greater. The rare speciesEuastrum germanicum andHeimansia pusilla had been only incidentally recorded in The Netherlands.
