# Ecological Limits > **Machine-Evolution Nexus:** [[articles/Digital Darwinism and the Invisible World of Machine Evolution|Digital Darwinism and the Invisible World of Machine Evolution]] provides the evolutionary and computational context for this supporting concept. **Domain:** Ecology / Systems **Doc Type:** Supporting Canonical Node **Maturity:** Developed ## Definition Ecological limits are thresholds or constraints beyond which environmental systems lose capacity, stability or regenerative function. ## Nexus Context They are not fixed independently of technology and behavior, but neither are they abolished by optimization. Compute and continuity infrastructures remain planetary systems. ## Relationships [[wiki/Ecological Constraint|Ecological Constraint]], [[wiki/Planetary Boundaries|Planetary Boundaries]], [[wiki/Sustainability|Sustainability]], [[wiki/Systems Ecology|Systems Ecology]] ## Sources / Provenance - Developed from the cited research in the central article and the surrounding continuity, rights and evolutionary architecture.
