Facilitation of phosphate assimilation by aquatic mycorrhizae of , Michxfungicidal medium (i.e., Captan). Incorporation of .Porthophosphate into root tissue in short-term incubations was over 85% greater for plants with active mycorrhizae. In addition, we measured a fine-scale iron gradient and elevated concentrations of solid-phase phosphate in the extensive sheath sur

Phosphorus balance of a polytrophic shallow lake with the consideration of phosphorus releaseorus release (P-release) was studied. The investigated Lake Blankensee covers an area of 2.9 km. with an average depth of 1.2 m (volume 3.43 10. m.). The average summer chlorophyll-.concentrations range from 104 to 418 μg 1. (1992–1995). Secchi-depths from 0.2 to 0.3 m are typical in summer. Massive

The occurrence of heterotrophic bacteria decomposing some macromolecular compounds in shallow estuaro and Jamno.The abilities of heterotrophic bacteria to decompose proteins, lipids, starch, nucleic acids, pectin, chitin and cellulose were determined. Characteristic features among the bacteria in the lakes under study were to decompose a wide spectrum of organic macromolecular compounds. Most bact

Picoplankton and other size groups of phytoplankton in various shallow lakes m) located in the Polish part of Pomerania. Samples were taken from the pelagial zone in August 1993 and 1994. Phytoplankton composition, abundance and biomass were investigated within the three main size groups, i.e. pico-, nano- and phytoplankton >20 μm. Picoplankton numbers ranged from 3.2 x 10.

Influence of small-scale turbulence and large-scale mixing on phytoplankton primary productioncially in shallow polymictic lakes, experiments were run on three different scales. (1) To achieve more natural conditions in bottles used for . incubation measurements of primary production, bottle stirrers were designed and tested .. The operation of the bottle stirrers guaranteed a homogeneous di
