| Description | Long-term studies of benthic macroinvertebrate assemblage composition can serve as a basis for fluvial ecosystem impact assessment on local, regional and even a global scale. However, the appropriate data are infrequent. One of the available datasets comprises information on Ephemeroptera of the Czech Republic, collected in the 1950's, 1990's and today. The 1st period of the investigation represents the time before intensive development of industry and agriculture in the 1970's and 1980's; the 2nd period can be characterised as the beginning of the phase of some mitigation of organic pollution and acidification. Reducing of organic pollution and acidification stressed the impacts of stream morphology degradation and changed hydrology in the 2nd period, which are further intensified by climate changes today (3rd period). |
