DISCLAIMER — Real Science, No Invented Bridge Constant, Includes a Complication

Why no UTAC/CREP/AFET bridge: not only because the cited literature already provides the necessary quantitative structure -- a deliberate choice. This project's highly speculative AFET/UTAC experiments must never stand in the way of climate/ecology topics being accessible and usable to people who don't work inside that construct and aren't looking for renormalization groups. Real, checkable science, without the burden of an unproven framework. See PACKAGE_REGISTRY.md's "Why no UTAC/CREP/AFET bridge in the climate/ecology series" (2026-08-31) in the GenesisAeon workspace root for the full canonical note.

Status: Real, independently verified science. NO UTAC/CREP/AFET bridge, NO invented Γ value.

Where this package came from

Third and last of the three remaining candidate gap-topics identified from UTACnextSteps.txt (Grok + a separate Claude-Code-Web session proposing 5 environment/climate/species-protection gap-topics for GenesisAeon). See coral-reef-utac (P114)'s DISCLAIMER.md for the full account of why that dialogue's specific numeric claims — invented Γ_tipping values, an invented "Pressure-inverted UTAC" formula falsely presented as extracted from the codebase, a wrong "strict GPL-3.0 template" claim, and a non-existent git branch — did not survive independent verification, confirmed by the other session itself when the discrepancies were surfaced back to it.

Grok's original framing for this topic ("network criticality of pollinators... CREP metrics for coherence of pollination networks") was not adopted as stated -- no real, independently-derivable Γ or CREP-coherence value exists for pollination networks in the literature surveyed here. Inst

pollinator-network-utac

GenesisAeon Package 116 — real, independently verified pollinator decline and plant-pollinator network-cascade science. Third of the three remaining candidate gap-topics from UTACnextSteps.txt (after coral-reef-utac P114 and biodiversity-utac P115). Deliberately has no UTAC/CREP/AFET bridge and no invented Γ value — see DISCLAIMER.md.

For a plain-language explanation of the same topic (German, no jargon, written for general audiences), see WHITEPAPER.md.

Deliberately not one-sided

does_adding_managed_pollinators_always_help_wild_pollinator_networks() returns False — Valido et al. (2019) found that beekeeping (managed honeybee introduction, often done with pollinator-conservation intent) measurably reduced wild-pollinator diversity and disrupted network structure in a real field study. "More pollinators" is not automatically good for wild pollinator biodiversity.

What's real here

• Hallmann et al. (2017, PLOS ONE)* — the real Krefeld study:
• total flying insect biomass in 63 German protected areas fell by an
• average of 76% (up to 82% at midsummer peak) over 27 years
• (1989–2016) — measured inside protected areas, pointing to
• landscape-level or climatic drivers beyond local habitat loss.
• IPBES (2016) Pollinator Assessment — the real, official global
• figures: 35% of crop production volume depends on animal
• pollination, worth USD 235–577 billion/year; pollinator-dependent
• production volume grew 300% in 50 years, even as 16.5% of vertebrate
• pollinators are threatened and 37%/31% of regional bee/butterfly
• populations decline.
• Vanbergen et al. (2017, Functional Ecology)* — a real,
• published network-structure finding: the properties that make a
• plant-pollinator network resistant to small disturbances are the
• same properties that can make it prone to cascading collapse once a
• structurally important species is lost — robustness and fragility
• are two faces of the same real structure.
• Valido, Rodríguez-Rodríguez & Jordano (2019, Scientific

• in a real field study, a real complication to "more pollinators is
• always better."
