Modern diatom, cladocera, chironomid, and chrysophyte cyst assemblages as quantitative indicators for the reconstruction of past environmental conditions in the Alps. I. Climate
Diatom, chrysophyte cyst, benthic cladocera, planktonic cladocera, and chironomid assemblages were studied in the surface sediments of 68 small lakes along an altitudinal gradient from 300 to 2350 mExpand

Younger Dryas and Allerød summer temperatures at Gerzensee (Switzerland) inferred from fossil pollen and cladoceran assemblages
Linear- and unimodal-based inference models for mean summer temperatures (partial least squares, weighted averaging, and weighted averaging partial least squares models) were applied to aExpand

Modern diatom, cladocera, chironomid, and chrysophyte cyst assemblages as quantitative indicators for the reconstruction of past environmental conditions in the Alps. II. Nutrients
Surface sediments from 68 small lakes in the Alps and 9 well-dated sediment core samples that cover a gradient of total phosphorus (TP) concentrations of 6 to 520 μg TP l-1 were studied for diatom,Expand

Quantification of biotic responses to rapid climatic changes around the Younger Dryas — a synthesis
To assess the presence or absence of lags in biotic responses to rapid climatic changes, we: (1) assume that the δ18O in biogenically precipitated carbonates record global or hemispheric climaticExpand

An intercontinental comparison of chironomid palaeotemperature inference models: Europe vs North America.
Abstract Chironomid-temperature inference models based on North American, European and combined surface sediment training sets were compared to assess the overall reliability of their predictions.Expand

Holocene timber-line dynamics at Bachalpsee, a lake at 2265 m a.s.l. in the northern Swiss Alps
Palaeobotanical analysis and radiocarbon dating of lake sediments from Bachalpsee (2265 m a.s.l.), a small lake above the present-day timber-line in the northern Swiss Alps reveals that the regionExpand

Response of the chydorid faunas to rapid climatic changes in four alpine lakes at different altitudes
Abstract The subfossil assemblages of Chydoridae from Late Glacial/Preboreal sediments of four sites from 603 m to 2290 m asl were analysed to trace the community response to rapid climatic warmingExpand

The significance of chironomid analysis (Insecta: Diptera) for paleolimnological research
Abstract Consideration of the dipteran family Chironomidae is an important aspect of microfossil analysis of lake sediments because chironomids provide information on the ecological characteristicsExpand

Empirical relationships between cladoceran fauna and trophic state in thirteen northern German lakes: analysis of surficial sediments
The cladoceran faunas from 13 northern German lakes (the Plön district) of different trophic levels were analysed using the bosminid and chydorid remains in the surficial sediment as an integratedExpand

Cladocera in space and time: analysis of lake sediments
Shells of Bosminidae and Chydoridae are quantitatively preserved in lake sediments. The chronological deposition of these remains provides the means for longterm observation of these Cladocera, bothExpand
