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

Food-web changes caused by removal or size-selective depletion of predators, herbivores or other consumers.

Drivers

introduced species; land use; extraction; pollution; management

Inputs

pressure; propagules; contaminants; removals

Outputs

altered hydrology; food webs; regeneration; erosion; connectivity

Spatial scales

site → island → watershed

Temporal scales

event → decades

Validity and limits

Context-specific; do not extrapolate across habitat, season, elevation, salinity or disturbance state without evidence.
