Primes¶
- Maturity Mismatch
- In biology and ecology, a species with long generation time faces predation or harvesting tuned to short generation times, and its long-tenor reproductive capacity cannot accelerate, so the population collapses despite genetically healthy individuals.
This sourceShows that reduced age at maturity sharply slows population recovery in cod: long-tenor reproductive replacement cannot accelerate to match short-tenor harvesting, so depletion outpaces recovery even when individuals are sound.
Supported in partVerified against the publisher's abstract
Hutchings's abstract backs the idea that exploitation can leave a harvested stock with slow or negligible recovery, but not the claim's long-generation-time mechanism or its 'genetically healthy individuals' clause.
“These results underscore the potential for fishing-induced changes to life history traits alone to generate slow or negligible recovery in marine fishes, exacerbating negative impacts on population growth resulting from ecosystem-level alterations to interspecific competition and predation.”

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? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
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.
