Glacier retreat could harm bees: Swiss research

Changing fauna caused by melting glaciers could make it more likely for bees to pass diseases on to one another. This is shown by a new study led by the University of Lausanne in Switzerland. Normally, wild bees and honeybees avoid each other whilst foraging by specialising in different plant species. This natural separation reduces the risk of cross-contamination with pathogens. However, as a result of changes to the plant world caused by glacial melt, bees are increasingly using the same food…
