Bee declines driven by combined stress from parasites, pesticides, and lack of flowers.
Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined; bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by humans. Climate change is likely to exacerbate these problems in the future. Stressors do not act in isolation; for example, pesticide exposure ca...

In part this reflects conflation 10 of data for domestic honeybees, numbers of which are largely driven by economic factors, 11 with those for wild bees, many of which have undergone marked range contractions but for 12 the majority of whic...
متن کاملThe relationship between managed bees and the prevalence of parasites in bumblebees
Honey bees and, more recently, bumblebees have been domesticated and are now managed commercially primarily for crop pollination, mixing with wild pollinators during foraging on shared flower resources. There is mounting evidence that managed honey bees or commercially produced bumblebees may affect the health of wild pollinators such as bumblebees by increasing competition for resources and th...

متن کاملDisentangling urban habitat and matrix effects on wild bee species
In face of a dramatic decline of wild bee species in many rural landscapes, potential conservation functions of urban areas gain importance. Yet effects of urbanization on pollinators, and in particular on wild bees, remain ambiguous and not comprehensively understood. This is especially true for amenity grassland and extensively managed wastelands within large-scale residential housing areas. ...
