New study shows European bees have become less widespread over last century
Researchers analyzed more than four million records to reveal that wild pollinators in Europe are disappearing from many areas where they were found a hundred years ago.
Data covers most European species
Scientists at the Doñana Biological Station examined records spanning roughly eighty-eight percent of bee and hoverfly types across the continent. The team looked at both how many species exist in specific locations and the total geographical area they occupy.
Bee populations declined significantly
On average, bee species have lost about one-third of their historical range during the past hundred years. This trend indicates that insects are leaving places where they once lived regularly.
Hoverflies showed different trends
Hoverflies experienced a slight increase in their geographical spread throughout the last century. However, most of this growth happened during the earlier decades rather than recently.
