Primes¶
- Coastal Squeeze
- Coastal ecology (origin): salt marshes, mangroves, mudflats, and dune systems squeezed between rising seas and fixed coastal development. Mountain ecology: high-altitude species experiencing an altitudinal squeeze as warming shifts suitable conditions upslope, with the summit as a fixed boundary against which the squeeze ends in extinction.
This sourceDocuments the 'escalator to extinction' — high-altitude species pushed upslope by warming until the summit (a fixed boundary) ends the range in extirpation.

Freeman et al. show Peruvian mountain birds shifting upslope with warming and mountaintop species disappearing, supporting the mountain squeeze; the coastal-ecology half is not covered.
“High-elevation birds on the Cerro de Pantiacolla are indeed riding an escalator to extinction. Several high-elevation species seem to have disappeared”

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.
