Seasonal ecosystem variability in remote mountain lakes: implications for detecting climatic signals in sediment records.

Popis výsledku v původním jazyce

The main patterns of seasonal variability in the ecosystems of nine lakes in Europe are discussed with the implications for recording climatic features in their sediments. Despite the diversity in latitude and size, the lakes showed a number of common features. They were phosphorus limited, ice-covered between 5-9 months, and all but one were dimictic. Two types of lakes were distinguished according to the number of production peaks during the ice-free season. Lakes with longer summer stratification tended to have two productive periods: one at the onset of stratification, and the other during the autumn overturn. Lakes with shorter stratification had single peak during the ice-free period. All lakes presented deep chlorophyll maxima during summer stratification, and subsurface chlorophyll maxima beneath the ice. The major chemical components showed a short but extreme dilution during thawing. Certain lake features may favour the recording of particular climatic fluctuations.
