Indicators for Climate Change Impacts - Rivers in warm ecoregions, Small rivers

Increased macrophyte/algae growth

Stressor type Temperature
Responding parameter group Biological parameters
Responding parameter Increased macrophyte/algae growth

Response description

Higher water temperatures and lower discharge enhance macrophyte and algae growth. Furthermore, higher temperatures increase mineralisation processes and deliver more nutrients for macrophyte and algae growth.

Secondary effects

Oxygen depletion during night time and oxygen over-saturation at day time will affect aquatic communities.

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

Water temperature (mean monthly values)

Justification of indicator

Mean monthly temperatures indicate overall temperature increase.
