The loss in the number of currently red-listed species (−40%) in the regional species pool was even larger indicating that species with specific habitat requirements, which are usually more threatened by habitat change than generalist species, were indeed most vulnerable. (ed.

Ein Einteilungsversuch der Wasserpflanzengesellschaften. When two time steps (1950s vs. 2010/2011) were compared and values were normally distributed (according to a Shapiro–Wilk test), the To achieve sufficient comparability among the different data sets, only hydrophytic species (plants with morphological adaptations to life in water in the form of submerged or floating leaves) were included in the analyses.

Species loss was related to marked changes in macrophyte community composition with nearly half of the species present in the relevés in the 1950s either having disappeared until 2010/2011 or having been replaced by other species.

Both the decrease in the regional species pool and in the plot-level diversity were dramatic with the consequence that most water courses are colonised nowadays by only species-poor, relatively uniform communities that contain a high proportion of species adapted to disturbance.

Dynamik und Konstanz von Flora und Vegetation ausgewählter Fließgewässer Niedersachsens 1946 bis 1986.
