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
- Changes in survival, reproduction or movement caused by population density.
- Drivers
- behavior; currents; wind; habitat continuity; barriers; season
- Inputs
- organisms; propagules; reproductive output
- Outputs
- colonization; gene flow; recruitment; population persistence
- Spatial scales
- patch → island → inter-island
- Temporal scales
- minutes → generations
- Validity and limits
- Context-specific; do not extrapolate across habitat, season, elevation, salinity or disturbance state without evidence.
