Fiji ant study provides new evidence of insects’ decline on remote islands

DNA analysis of endemic specimens in museums finds 79% of ant populations in Pacific archipelago are shrinking

Island-dwelling insects have not been spared the ravages of humanity that have pushed so many of their invertebrate kin into freefall around the world, new research on Fijian ant populations has found.

Hundreds of thousands of insect species have been lost over the past 150 years and it is believed the world is now losing between 1% and 2.5% a year of its remaining insect biomass - a decline so steep that many entomologists say we are living through an insect apocalypse". Yet long-term data for individual insect populations is sparse and patchy.
