The Holocene paleolimnology of Lake Sämbosjön, southwestern Sweden

摘要: The Holocence paleolimnology of Lake Sambosjon is described using geochemical and diatom analyses. objective this study the reconstruction major changes in trophic state productivity, to interpret causative processes. accumulation organic matter indicates a relatively high productivity early Holocene, analysis pH. A succeeding decrease lowering pH recorded from about 8000 BP. If lake development had been primarily edaphically conditioned, viz. determined by nutrient supply catchment soils, such progressive oligotrophication would represent common temperate lakes. Between 6000 BP 4000 was characterized stable From analyses reveal an increase again state, This eutrophication, which continued throughout late caused exceptionally strong human influence on Sambosjon. increased nutrients cleared deforested soils changed provided basis for productivity.
