Lake Takem and Lake Krankesjon, two moderately eutrophic, shallow lakes in southern
Sweden, have during the past few decades shifted several times between a clear-water state …

In den nachfolgenden Unterkapiteln werden die in Deutschland vorkommenden Characeen
vorgestellt. Die Bearbeitung dieser Unterkapitel erfolgte unter Federführung der …

Charophytes have disappeared from several enriched lakes in Scania (southern Sweden)
since the 1940s. Poor light conditions, rather than a toxic effect of phosphorus or negative …

Periods with clear water and abundant submerged vegetation have alternated with periods
of turbid water and sparse vegetation during recent decades in Lake Tåkern and Lake …

The study is based on monitoring data on the seasonal variation during four (1996–1999)
vegetation periods, as well as long-term summer data on submerged vegetation, nutrients, light…

Submerged macrophytes play a key role in north temperate shallow lakes by stabilizing
clear-water conditions. Eutrophication has resulted in macrophyte loss and shifts to turbid …

A number of mechanisms result in a feedback between water clarity and macrophytes and,
consequently, the occurrence of alternative stable states in shallow lakes. We hypothesize …

Epiphyton samples same taken from different macrophyte species (three chararaceans
Potamogeton pectinatus L.). While some epiphyton taxa were evenly distributed, the density of …

With the aim to assess the combined and separate effects of waterfowl and fish on submerged
vegetation and macroinvertebrates, we performed a replicated selective exclosure study …

Background Plants and their heterotrophic bacterial biofilm communities possibly strongly
interact, especially in aquatic systems. We aimed to ascertain whether different macrophytes …
