    Notes: Knowledge of the environmental controls of carbon dioxide fluxes is essential for understanding the dynamics of carbon exchange between ecosystems and atmosphere. In this study we investigated soil respiration and moss photosynthesis as well as their contribution to the net carbon dioxide flux of two different wet tundra systems. During two summers, in situ carbon dioxide fluxes were measured in a tussock tundra and in a low-centre polygonal tundra on Taimyr Peninsula, central Siberia. Measurements were carried out by means of a multichannel gas exchange system. Results show pronounced differences in soil respiration rates as related to microscale topography, mainly due to differences of soil water table and soil temperatures. Modelling of soil respiration for individual microsites revealed differences of process performance with respect to both factors. The wet microsites showed the highest potential regarding an increase of soil respiration rates in warmer and drier climate change scenarios. Another important process compensating the CO2 release from the soil was the photosynthesis of the moss layer, assimilating as much as 51% to 98% of the daily amount of carbon dioxide released from wet tundra soils. This result demonstrates the importance of mosses in the context of tundra ecosystem processes. The magnitude of net system fluxes of the whole system at the depression of the polygonal tundra was strongly influenced by changes in soil water table. Consequently, any changes of the hydrology, as anticipated in the context of global change, would effectively alter the carbon balance of wet tundra systems.

    Notes: Abstract Bacterial numbers and biomass associated with soils and plants from King George Island, Maritime Antarctica, were analysed by epifluorescence microscopy. Sampling was carried out during austral summer 1992/1993 at different sites in the vicinity of Arctewski Station. The sites were located at areas with different plant cover. Soil samples were taken to a depth of 50 cm. All microscopic analyses were carried out in the laboratory immediately after sampling. The bacterial community showed great variations related to soil organic matter and plant cover. Highest values of number and biomass of bacteria were found in the surface layers as well as on leaves of Deschampsia antarctica and Colobanthus quitensis. Lichen (Usnea antarctica, U. aurantiaco-atra) were much less covered with bacteria. Mean cell volume of bacteria can be regarded as an important descriptor of the bacterial community. Changes in this parameter can be related to environmental factors. Fungi and yeasts were seldom observed.

    Notes: Summary The depth distribution and composition of residual amino acids was determined in December 1980 in the Bransfield Strait. The major components were aspartic and glutamic acids together with alanine, glycine and serine. Non-protein amino acids were not found in significant amounts. On the average, the amino acids accounted for 25% of the total organic carbon and 50% of the organic nitrogen. Amino acid nitrogen/chlorophyll ratios indicated that in most euphotic zone samples phytoplankton in good physiological condition was present whereas heavily degraded material was found in deeper water layers. Statistical treatment and cluster analysis show distinct differences between euphotic and aphotic zone samples which could be used to characterize phytoplankton communities.

    Notes: Abstract Growth rates of natural bacterial communities from Antarctic soils are analysed by an epifiuorescence microscopic method using data of microcolonies (colony number and colony areas). Incubations are performed on polycarbonate filters which are put on cellulose pads soaked with soil extracts, different concentrations of naturally occuring carbohydrates, polyols, and leucine. Concentrations of individual substrates were in the range of naturally occuring levels. The results showed that the growth of bacterial microcolonies could best be stimulated with glucose, sucrose, maltose, sorbitol, and mannitol. Leucine stimulated growth to a lower extent than glucose. Data on bacterial biomass production calculated from this approach are discussed in relation to those from tracer techniques carried out with 14C-labelled glucose from earlier experiments.
