City pavements can show unlikely havens for wild bees and different bugs, a survey on the streets of Berlin suggests.
Sophie Lokatis on the Free College of Berlin and her colleagues explored 200-metre-long sections of pavement at 12 places within the German metropolis. They recorded insect nest places and picked up people discovered on the entrance to nests, crawling on the pavement or flying inside a metre of the bottom. Additionally they analysed soil from nests utilizing DNA sequencing strategies.
