A biodiversity cascade threshold is crossed

Window: Multi-year threshold-approach; discrete threshold-cross; multi-decade downstream

What this is

A specific biodiversity threshold — species-population floor, coral-cover minimum, pollinator-abundance minimum, ice-obligate seal population floor, LPI composite — crosses a non-reversible line producing cascade effects on ecosystem services and dependent sub-populations. F-CT-9 ADAPTATION-REQUIRED fires on fisheries + agriculture + pharmaceutical + climate-regulation substrates.
