Última Vertical distribution of meiofauna and the efficiency of the Van Veen grab on sandy bottoms in lake Grevelingen (the Netherlands) OMA Heip, C.H.R.; Willems, K.A.; Goossens, A.. Comparison of density estimates of Nematoda and Harpacticoida obtained by a Van Veen grab and SCUBA diving from a sandy sediment in shallow water shows that Harpacticoida are sampled efficiently with the grab but Nematoda are not. For the Nematoda, total density is underestimated and the relative abundance of surface-dwellers is overestimated. Samples obtained with a Van Veen grab from which the material is collected in a bucket and subsampled afterwards have a much smaller statistical variability than samples obtained with other methods.

Ano: 1977 URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=3570 Long-term evolution of the meiofauna at a sandy station in lake Grevelingen, the Netherlands OMA Willems, K.A.; Sharma, Y.; Heip, C.H.R.; Sandee, A.J.J.. Data on density, diversity and species number of harpacticoids and nematodes from a 3 m deep station in Lake Grevelingen are reported over the period 1975-1980. Vertical distribution of both copepod and nematodes densities are added. Over the 6 years period 95 species of nematodes and 26 species of harpacticoids have been identified. Neither diversity nor species number of harpacticoids changed significantly over the period. Nematode diversity and species number showed considerable changes, and especially the species composition evolved drastically over the years. The changes in feeding types among nematodes are discussed. Densities of both copepods and nematodes changed substantially over the 6 years period. Concurrent with a significant rise of the redox...
