1. 1. Long-term development of subalpine lakes : effects of nutrients, climate and hydrological variability as assessed by biological and geochemical sediment proxies

   Sammanfattning : Sediment records of two Italian subalpine lakes (Lake Garda and Lake Ledro) were analyzed in order to reconstruct their ecological evolution over the past several hundred years. A multi-proxy and multi-site approach was applied in order to disentangle the effects of local anthropogenic forcings, such as nutrients, and climate impacts on the two lakes and their catchments.

   Sammanfattning : Increasing nutrient concentrations (eutrophication) and water color due to dissolved organic matter (brownification) pose continuous threats to freshwater ecosystems worldwide, threatening ecosystem services like drinking water supply. Changing the increasing trends of eutrophication and brownification on our aquatic ecosystems is challenging. LÄS MER
