Objetivo NIPHYS (Nitrogen Physiology of Forest Plants and Soils) is an investigation on the effects of soil-borne and deposited nitrogen on forest organisms and soils along a climatic transect from North to South Europe. The present proposal will extend this transect as part of an East-West extension, and supply baseline data in order to test hypotheses which were developed on the North-South-Transect along an East-West line. This line should reach from the Czech Republic (and may be extended further east in future) to England. The proposal will contribute to the understanding of nitrogen transformations in forest ecosystems, and by adding sites with high and low sulfur deposition in a continental climate, it will improve predictions on effects of changing depositions and global climate change on broad-leafed and coniferous trees. The present proposal is of great importance and significance within the objectives of NIPHYS, because it is based on an existing data-set of catchment scale nutrient budgets which reach back to 1975. In the past special emphasis was given to the sulfur dynamics in these catchments, and nitrogen cycling had not been investigated although nitrate effluxes were high. Adding the approach of NIPHYS to these study areas and using the modelling capacity existing in the Czech research group (and which is missing in NIPHYS) makes an ideal basis for a fruitful cooperation of the EEC and Eastern European Countries. In the present proposal the measurements of natural stable isotope abundances of 18O and 15N will give a new dimension of interpretation to the Czech data set. In addition, tracer studies using 15N will give information on nitrogen turnover and transformation in an environment which had received highest pollution deposition in Europe. Both informations will supplement the present NIPHYS activity.
