In the fragmented mountain landscapes of Central and South America, hummingbirds and bromeliads have spent millions of years shaping one another — a partnership so generative that it doubles the pace at which new plant species emerge. Researchers at the University of Reading have now quantified this co-evolutionary force, finding that hummingbird pollination drives bromeliad speciation at nearly twice the rate of any other pollinator. What took nature millions of years to build, however, now faces rapid unraveling: habitat loss and climate change threaten both partners, and the very intimacy t

Hummingbird-pollinated bromeliads evolve twice as fast as other pollinated species, but habitat loss and climate change threaten this co-evolutionary partnership with economic implications for pineapple production and biodiversity-dependent sectors.

Potential long-term supply risks for pineapples and bromeliad-derived products; increased prices if hummingbird populations decline; reduced availability of ornamental bromeliad species; impacts on food security in regions dependent on pineapple cultivation.
Governments may need to implement habitat protection policies, climate change mitigation strategies, and conservation programs for hummingbird populations. Agricultural sectors may require adaptation strategies and investment in pollinator-friendly farming practices. International biodiversity agreements may be strengthened.
