Indicators for Climate Change Impacts - Rivers in warm ecoregions, Small rivers
Changes in life strategies
| Stressor type | Hydrology / Morphology |
|---|---|
| Responding parameter group | Hydromorphological parameters |
| Responding parameter | Changes in life strategies |
Response description
If small rivers become intermittent, species with a bivoltine life cycle can not survive and the community will change to univoltine species with an early emergence period.
Secondary effects
Overall change of aquatic community
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
Drought periods
Justification of indicator
As gauging stations are not installed in most small headwater streams, drought periods can be easily recorded by visiting the respective streams.
