Global study finds that species numbers reported in the wild fell sharply between 1990 and 2015
The number of wild bee species recorded by an international database of life on Earth has declined by a quarter since 1990, according to a global analysis of bee declines.
Researchers analysed bee records from museums, universities and citizen scientists collated by the Global Biodiversity Information Facility, (GBIF) a global, government-funded network providing open-access data on biodiversity.
