Indicators for Climate Change Impacts - Lakes in warm ecoregions, Shallow lakes
Oxygen depletion
| Stressor type | Temperature |
|---|---|
| Responding parameter group | Physico-chemical parameters |
| Responding parameter | Oxygen depletion |
Response description
High temperatures will stimulate phytoplankton growth, which will lead to oxygen depletion of profundal habitats.
Secondary effects
Low oxygen intolerant species will vanish
Specification of relevant ecosystem type
Relevant for all lakes 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
Oxygen concentration of the bottom water in summer
Justification of indicator
The parameter is easy to record and often incorporated into routine water chemistry monitoring.
