    Among plant, amphibian, reptile, bird and mammal extinctions since AD 1500, 75% involved overexploitation, agriculture, or both, often alongside invasive aliens.

    “Of all the plant, amphibian, reptile, bird and mammal species that have gone extinct since ad 1500, 75% were harmed by overexploitation or agricultural activity or both (often in combination with the introduction of invasive alien species 7 ).”

      The Results (section 3; page unavailable) report that, among the 215 extinct species in the five taxa, 58% were affected by biological resource use, 28% by agriculture or aquaculture, and 58% by alien species. They also say species commonly had more than one listed threat, supporting the possibility of combined threats. The paper does not report that 75% were affected by overexploitation or agriculture or establish how often those threats specifically coincided with alien species. (LLM, conf=0.83)

  • Premisecitation

    For many species, the mix of threats that determines extinction risk will shift within the next few decades.

    “Finally, the balance of threats driving extinction risk for many of the world's species will change, even over the next few decades 3 .”

  • Premisecitation

    Research indicates that Red List categories based on projected climate-change extinction risk are more reliable than earlier believed.

    “Finally, studies have shown Red List categorizations reflecting projected extinction risk from climate change to be more robust than was previously thought 6 .”

    • cites [6] Keith, D. A. et al. Conserv. Biol. 28, 810–819 (2014). source

      The Introduction (page not supplied) describes earlier doubts about whether Red List criteria can detect climate-change extinction risk. The Factors influencing performance section reports that assessments for later in the twenty-first century were robust to missing data, but the study examined one amphibian species and cautions that early detection can depend on assessing criterion E. The claim overgeneralizes that qualified finding to Red List categorizations broadly. (LLM, conf=0.83)

    Effective methods exist to reduce the damage from overexploitation and agriculture.

  • Findingcitation

    The species groups with complete assessments are not a random selection from the tree of life; they tend to be better studied.

    “The comprehensively assessed groups included here are not a random sample from the tree of life 1 , but those that are generally better-studied.”
    Quote in the paperNot a substantial claim1 of 1 sources checked
    • cites [1] Brooks, T. M. et al. Sci. Data 3, 160007 (2016). source

      The Methods section lists particular taxonomic groups with comprehensive assessments and distinguishes them from a separate taxonomically stratified effort intended to be representative. The Data Records section says some assessed groups are better known than others, but it does not establish that comprehensively assessed groups are generally better studied than groups outside that selection. Page numbers are not available in our copy. (LLM, conf=0.81)

    Interpretationcitation

    Since farming and overexploitation often overlap with biodiverse fertile areas, the study's patterns likely apply to many unassessed species.

    “Because agricultural activity and overexploitation tend to occur in fertile places with naturally high levels of biodiversity 4 , the patterns emerging from our analysis probably extend to many of the other species that have not yet been assessed.”

    Human development and population growth will continue and increase the impacts of overexploitation and agricultural expansion.

    “But human development and population growth mean that the impacts of overexploitation and agricultural expansion will also increase.”

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Hundreds of species and myriad populations are being driven to extinction every year.

    “Hundreds of species and myriad populations are being driven to extinction every year (1–8).”

    From Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines (2017) · cites this paper as [5]

    The ON THE LIST section reports threats to 8,688 threatened or near-threatened species, and WHAT NEXT? discusses species extinctions since AD 1500. Neither section says that hundreds of species or myriad populations are driven to extinction every year; the annual rate and population-extinction claims are unsupported. (LLM, conf=0.84)

  • Combating climate change alone will not be enough to prevent or possibly even slow further biodiversity loss unless damaging land/sea use change and direct exploitation are also tackled with similar ambition and determination.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-02.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-02.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
