Open AccessSedimentary, littoral and planktic diatoms show different diversity patterns and assembly mechanisms in mountain lakes of the northern European Alps
This study analysed diversity patterns of sedimentary, littoral and planktic diatoms in 43 mountain lakes in the northern European Alps and identified processes that contribute to these patterns. Linear regres...

Open AccessUnravelling climate change impacts from other anthropogenic influences in a subalpine lake: a multi-proxy sediment study from Oberer Soiernsee (Northern Alps, Germany)
Mountain lakes are increasingly impacted by a series of both local and global disturbances. The present study reveals the eutrophication history of a remote subalpine lake (Oberer Soiernsee, Northern Alps, Ger...

Open AccessDepth-distribution of lake benthic diatom assemblages in relation to light availability and substrate: implications for paleolimnological studies
We analyzed the depth distributions of benthic diatoms in two adjacent, but hydrologically distinct subalpine lakes (Lakes Soiernseen, S-Germany). Lake Unterer Soiernsee is affected by marked water-level fluct...

Spatio-temporal distribution pattern of the picocyanobacterium Synechococcus in lakes of different trophic states: a comparison of flow cytometry and sequencing approaches
In this study, we aimed to investigate the spatio-temporal distribution patterns of the picocyanobacterium Synechococcus, an important contributor to primary production in many freshwater lakes. Our study sites w...

Water research in Germany: from the reconstruction of the Roman Rhine to a risk assessment for aquatic neophytes
Germany does not only have a long tradition in water research, but a very active community of scientists and practitioners working on a vast range of “water topics.” This thematic issue, which was initiated by...

Hybridisation and cryptic invasion in Najas marina L. (Hydrocharitaceae)?
Macrophytes have been used as bioindicators for eutrophication assessment in freshwaters required by the European Water Framework Directive (WFD). The red listed Najas marina s.l. is routinely mapped in Germany. ...

Predicting the potential distribution of neophytes in Southern Germany using native Najas marina as invasion risk indicator
Twenty-four aquatic neophytes have been introduced to Germany so far and at least 16 non-native species established stable populations in northern and north-western Germany. Invasive aquatic neophytes can caus...

Influence of the gender on growth and phenology of the dioecious macrophyte Najas marina ssp. intermedia
Growth experiments with macrophytes revealed anomalies in the growth and development of Najas intermedia. Further analyses showed that these anomalies were caused by differences between the male and female plants...

Does the process of drying submerged macrophytes affect community structure and composition of epiphytic diatoms?
This study investigates whether the process of pressing and drying a macrophyte host affects community structure and composition of epiphytic diatom communities. Epiphytic diatoms on submerged macrophytes from...

The quaternary structure of four crustacean two-hexameric hemocyanins: immunocorrelation, stoichiometry, reassembly and topology of individual subunits
Two-hexameric (2×6) hemocyanins from the brachyuran crabsCancer pagurus andCallinectes sapidus, the freshwater crayfishAstacus leptodactylus and the lobsterHomarus americanus were isolated and dissociated into na...

On the Role of Individual Subunits in the Quaternary Structure of Crustacean Hemocyanins
Among crustaceans, a widespread hemocyanin aggregate is the dodecamer (24S), composed of two hexameric halfs. According to computer correspondence analysis data (Bijlholt, unpublished), a one-point contact bet...
