Glacier Microbiome Succession

DISCLAIMER — Real Deglaciation-Succession and GFS-Microbiome Science, No Framework Bridge

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, three peer-reviewed papers, two open-access copies fetched directly. NO UTAC/CREP/AFET bridge.

Where this package came from

Surfaced as recommendation #5 in an external "Deep Research" audit of apps-hub shared by Johann (downloads/deep-research-report(1).md, 2026-09-05). Per this ecosystem's standing practice of never trusting an AI-generated audit's citations at face value, all three proposed papers were independently re-searched and re-fetched from open-access mirrors before anything was written here -- the audit was treated as a lead pointing at real literature, not as a source to copy from. See PACKAGE_REGISTRY.md's "External deep-research audit (2026-09-05)" section for the full verification trail.

glacier-microbiome-succession-utac

GenesisAeon Package 129 — real deglaciation-succession and glacier-fed- stream (GFS) microbiome science. Deliberately has no UTAC/CREP/AFET bridge — see DISCLAIMER.md.

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

Where this package came from

Surfaced as a specific recommendation in an external "Deep Research" audit of apps-hub (2026-09-05) — independently re-verified from open-access sources before building, not copied from the audit's own citation text. See PACKAGE_REGISTRY.md's "External deep-research audit" section.

What's real here

• Losapio et al. (2025, Nature Reviews Biodiversity)* — deglaciation
• drives a real, non-monotonic biodiversity response: an initial
• habitat-availability peak, then homogenization and
• local-to-regional decline — not a simple "glaciers melt,
• biodiversity drops" story.
• Ezzat, Peter, Bourquin et al. (2025, Nature)* — the first global
• atlas of the GFS bacterial microbiome, 152 streams across Earth's
• major mountain ranges: 62.2% of bacterial ASVs are range-specific,
• only 0.42% (165 ASVs) form a cosmopolitan core. This microbiome is
• not globally uniform.
• Bourquin, Peter et al. (2025, Nature Communications)* —
• 2070–2100 (SSP3) projections for 164 GFS: streamwater temperature
• +306.7%, conductivity +88.2%, turbidity −44.4%, benthic
• chlorophyll‑a +339.7%, bacterial abundance +88.5%, bacterial
• Shannon diversity +6.2%, mean nearest taxon distance +3.5% (all
• median relative change, with reported IQRs).

Deliberately not one-sided

do_large_relative_percentages_imply_large_absolute_change() returns False — GFS are cold, near-freezing systems, so a modest absolute warming produces a huge relative percentage almost mechanically; +306.7% does not mean "the stream got three times hotter" in any everyday sense.

does_this_package_recompute_p99_peak_water() and does_this_package_recompute_p123_rle_status() both return False — this package is related to, but does not duplicate or validate, glacier-buffer-utac (P99), freshwater-ecosystem-stressors-utac (P106), or tropical-glacier-ecosystem-rle-utac (P123).
