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
- Indirect multi-level food-web changes triggered by alteration of predators, herbivores or other consumers.
- Drivers
- species abundance; resource availability; habitat structure; disease; season
- Inputs
- prey; plants; hosts; partners; detritus
- Outputs
- mortality; nutrient transfer; regulation; habitat modification
- Spatial scales
- individual → community → ecosystem
- Temporal scales
- seconds → generations
- Validity and limits
- Context-specific; do not extrapolate across habitat, season, elevation, salinity or disturbance state without evidence.
