Negative effects of increased ozone concentrations and heat stress on bumblebees are exacerbated by microplastics

Abstract The intensity of environmental stressors increases due to global change. Under natural conditions, insect pollinators are experiencing multiple stressors simultaneously which may exacerbate the negative effects of individual stressors. Using a fully crossed factorial des...

Highway to brood cell: bumblebees ingest and transfer tire wear particles more frequently than polystyrene microplastics

Abstract Pollinators like bumblebees are exposed to microplastics (MP) pollution during foraging. After returning to the colony foragers may subsequently spread MP in the nest or transfer ingested MP to larvae during cooperative brood care. Experimental studies have shown that MP...
