Habitat and ecology
- Ecological role
- Supports Atlas reasoning about ecosystem function, dependencies, threats, conservation leverage points and cross-module consequences.
Process and seasonal context
- Definition
- Repeated uptake, transformation and downstream transport of nutrients through stream food webs and sediments.
- Drivers
- organic inputs; redox; flow; biota; land cover
- Inputs
- N; P; organic matter; microbial substrates
- Outputs
- bioavailable nutrients; gaseous losses; retained nutrients; exported nutrients
- Spatial scales
- microhabitat → watershed → coastal ocean
- Temporal scales
- hours → years
- Validity and limits
- Context-specific; do not extrapolate across habitat, season, elevation, salinity or disturbance state without evidence.
