Název v původním jazyce

Effects of nitrate nitrogen pollution on Central European unionid bivalves revealed by distributional data and acute toxicity testing

Popis výsledku v původním jazyce

Studies from Central Europe have shown a relationship between the impaired population status of threatened freshwater mussel species and elevated nitrate nitrogen concentrations in running waters. 2. Causal mechanisms, however, remain unknown, and no experimental data or comprehensive studies involving more species are available, which causes uncertainty in prioritizing conservation actions. 3. This study uses both descriptive and experimental approaches to identify the effects of nitrates on freshwatermussels. 4. Spatial co-occurrence of five native freshwater mussel species and nitrate concentrations were examined in a 7th-order river catchment with anthropogenically-induced increasing nitrate levels and declining populations of these species duringthe 20th century. 5. Acute toxicity of nitrates was then estimated for artificially reared juveniles of A. anatina and U. crassus using both lethal and sublethal test endpoints.
