Indicators for Climate Change Impacts - Lakes in cold ecoregions, Shallow lakes
Salinity
| Stressor type | Temperature |
|---|---|
| Responding parameter group | Physico-chemical parameters |
| Responding parameter | Salinity |
Response description
Warmer winters cause extreme rainstorms and heavy sea-salt deposition. Storms will lead to frequent turnover and changed stratification times, whereas increased salt deposition might affect water chemistry.
Secondary effects
Heavy sea salt deposition increase acidifying substances which will have effects on the entire food web.
Specification of relevant ecosystem type
Limited to lakes with silicious catchments prone to acidification.
Relevant ecoregion(s) according to Illies
Borealic Uplands (20), Tundra (21), Fennoscandian Shield (22), Taiga (23)
Suggested indicator
acidifying substances
Justification of indicator
These parameters are easy to record and often incorporated into routine water chemistry monitoring.
