Zooplankton oxygen consumption and nutrient release in relation to species composition, animals size and enviromental conditions in the Baltic Sea during May and August

<p>[EN] Zooplankton metabolism in terms of oxygen consumption and &ntilde;utrient rel&eacute;ase (ammonia, phosphate) were measiu'ed in the Baltic Sea, a temp&eacute;rate &aacute;rea with high envirormiental changes both in space and in time. Plankton of the surface layer were analysed with balance measurements in 4 size classes between 50 and 1000 nm during spring in 1988, 1990 and 1991, in summer 19^8 and 1990 as well. The use of electr&oacute;n transport system (ETS), and the Glutamate Dehydrogenase (GDH) activity as indicators for respiration and ammonia rel&eacute;ase respectively, enlarged the data density and made a three dimensional resolution available (May 1990, 1991). Data are in the range of the latitudinal dependend magnitude. They reflect slight interannual, more seasonal and regional aspects. Anim&aacute;is size, temperature, food concentration, and species composition influence the specific rates</p>
