Opis

The BIOGEOMON conference, held in Prague, September 1993, was dedicated to the use of geochemistry and biology in the elucidation of biogeochemical processes in the context of research on small catchments, which are natural systems that lend themselves to the study of environmental problems at the ecosystem level. This text, which contains reviewed papers from the conference, includes long-term studies of nutrient cycling in forested catchments, effects of anthropogenic action on streamwater chemistry, stable isotope studies for tracing biogeochemical processes, determination of the process rates and mathematical modelling of ecosystem behaviour and mass fluxes.
