Indicators for Climate Change Impacts - Wetlands in temperate ecoregions, Wetlands
Macrophyte transpiration
| Stressor type | Atmospheric CO2 concentrations |
|---|---|
| Responding parameter group | Physico-chemical parameters |
| Responding parameter | Macrophyte transpiration |
Response description
Elevated atmospheric CO2 led to increased emissions of CH4.
Secondary effects
Elevated atmospheric CO2 led to increased photosynthesis and reduced transpiration in macrophytes such as Orontium aquaticum. Reduced transpiration might lead to comparatively raised water table.
Specification of relevant ecosystem type
