    Notes: Abstract A comparative study of species composition, abundance and spatial distribution of the rotifers of Neva Bay (Gulf of Finland, Baltic Sea), between 1982–1993, was carried out. The rotifer fauna in the central basin of Neva Bay is determined by and originates in Lake Ladoga and is very similar to that of the Neva River. High turbidity and effect of winds affecting water residence time influence composition and density of rotifers in this shallow estuary. The importance of rotifer assemblages for evaluation of the quality of the estuary is discussed.

    Carbon content of some freshwater rotifers (1998)
    Springer
    Hydrobiologia 287-388 (1998), S. 355-360 
    Details
    ISSN: 1573-5117
    Keywords: Rotifers ; carbon content

    Topics: Biology
    Notes: Abstract Carbon content of rotifers from 14 species ( Keratella cochlearis, K. c. tecta, K. c. hispida, K. ticinensis, K. quadrata, Polyarthra remata, P. vulgaris, P. major, P. euryptera, Synchaeta sp., S. stylata, S. pectinata, Trichocerca capucina, Asplanchna priodonta) was determined with the high temperature combustion method of Salonen (1979). Rotifers for the carbon analysis were collected from different fresh water bodies in Russia (Lake Ladoga) and Finland (lakes Pohjalampi, Varaslampi, and two small ponds in Lammi). Average individual carbon mass of rotifers varied between 0.0064 and 0.058 μg in Keratella spp., 0.012 and 0.051 μg in Polyarthra spp., 0.020 and 0.133 μg in Synchaeta spp., 0.162 and 0.555 μg in A. priodonta. The carbon level in the studied rotifer species differed 100-fold ranging from 0.31% WW in A. priodonta to 31.5% WW in K. c. tecta. Body length/carbon mass and body volume/carbon mass regressions were established for the studied rotifers.
