| Abstract | | This proposal relates to the general framework of the OMES project, concerning the role of the marsh vegetations in the ecosystem 'Zeeschelde'. If future developments result in a considerable increase in reed vegetation, it will be important to know what happens to the reed deritus that is yearly compounds. These processes are studied within the OMES project.Another part of the reed deritus is a potential food source for the zooplankton, and the study of the transfer reeds- zooplankton is not included in the present OMES project. To study and quantify the transfer between detritus originating from reeds and zooplankton, we intend to use 15N tracer techniques (on which ANCH VUB has expertise) combined with knowledge on zooplankton metabolism (for which ECOL VUB is responsible). Plants cultured on 15N -enriched soils, become themselves enriched in 15N. This enrichment is passed on to the organisms feeding on these plants. Conversion rates are determined following the appropriate mass balance equations. |
