Drivers of the diversity and distribution of wild bees in a species poor region
Sydenham, Markus Arne Kjær (PhD Thesis;2016:23, Doctoral thesis, 2020-11-13)Bee diversity is declining globally. On a European scale, roughly 10% of the species are considered threatened, but the number may be even higher. The threatened status of bees depends on both the taxonomic and spatial ... -
Enhancing pollination is more effective than increased conventional agriculture inputs for improving watermelon yields
Sawe, Thomas; Eldegard, Katrine; Totland, Ørjan; Macrice, Samora; Nielsen, Anders (Peer reviewed; Journal article, 2020)Agricultural practices to improve yields in small‐scale farms in Africa usually focus on improving growing conditions for the crops by applying fertilizers, irrigation, and/or pesticides.
