Indicators for Climate Change Impacts - Rivers in warm ecoregions, Small rivers
Eutrophication
| Stressor type | Temperature |
|---|---|
| Responding parameter group | Biological parameters |
| Responding parameter | Eutrophication |
Response description
Eutrophication is promoted by nutrient input (e.g. by ferilizers) and high water retention time through low discharge.
Secondary effects
Oxygen depletion at night times
Specification of relevant ecosystem type
Relevant for all small rivers in warm ecoregions.
Relevant ecoregion(s) according to Illies
Iberian Peninsula (1), Italian Peninsula (3), Dinaric Western Balkan (5), Hellenic Western Balkan (6), Eastern Balkan (7)
Suggested indicator
Total phosphorus concentration, current velocity
Justification of indicator
Phosphorus is in many cases limiting primary production.
