Worldwide occurrence records suggest a global decline in bee species richness

Abstract

Highlights d The number of bee species found each year in GBIF data has declined since the 1990s d Approximately 25% fewer species were found between 2006 and 2015 than before 1990 d As records increase as a result of enhanced data mobilization, analysis uncertainty decreases d Both obstacles to data mobility and drivers of actual bee decline need addressing
