The influence of artificial stream bottom siltation on Ephemeroptera in emergence traps

The influence of artificial stream bottom siltation on the may fly biocenosis in the Breitenbach stream, near Schlitz, West Germany, was studied in an in situ experiment. In an artificially-silted emergence trap, numbers of Baetis vernus and Baetis rhodani fell to 16 % and 1 %, respectively of numbe...
