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
- Movement of organisms, nutrients, particles and water between estuarine and reef habitats.
- Drivers
- water flow; animal movement; wind; waves; habitat connectivity
- Inputs
- water; nutrients; organisms; organic matter; sediment
- Outputs
- subsidies; downstream effects; cross-realm coupling
- Spatial scales
- ridge → reef / ocean → land
- Temporal scales
- event → seasonal → continuous
- Validity and limits
- Context-specific; do not extrapolate across habitat, season, elevation, salinity or disturbance state without evidence.
