Primes¶
- Constraint Release
- In ecology, the enemy-release hypothesis explains invasive species reaching population sizes their native predators had held them below, and predator removal triggering prey overshoot.
This sourceStates and reviews the enemy-release hypothesis: invasive species freed from co-evolved natural enemies reach population sizes their native ranges held them below.

Domain-specific¶
- Enemy release hypothesis
- The enemy release hypothesis is an explanation in invasion ecology for why introduced species frequently achieve higher population densities and growth rates in their new range than they ever reached in their native range: the specialist natural enemies — co-evolved herbivores, parasitoids, pathogens, and parasites — that regulated the species' abundance at home are absent in the introduced range, and removing that regulatory load is sufficient to unlock population growth up toward the species' intrinsic biotic potential, independent of any change in the species' traits
This sourceStates the enemy release hypothesis: loss of co-evolved specialist enemies on introduction permits higher abundance in the new range without any trait change.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
