1967 warning on tropical mountains trapping species confirmed by beetle study

The study was carried out in the Área de Conservación Guanacaste (ACG) of Costa Rica, a UNESCO World Heritage SiteImagine yourself living on a mountaintop where the climate has been almost unchanged for thousands of years. Life evolves with amazing precision; generation after generation adjusts to cool , predictable temperatures. But then the world starts to warm. The mountain that was once a refuge slowly transforms into a trap, and its inhabitants are left with no cooler refuge.“This could happen,” warned renowned ecologist Daniel Janzen nearly six decades ago, states a report published by Phys Org. In a seminal paper in 1967, he argued that tropical mountain species, which are adapted to stable climates, would find it much harder to cope with rising temperatures than species from more v
