Short description of your pro: Intensive forest management has led to forest homogenization with associated changes to the biodiversity they host. Compensatory actions have been taken to counteract the negative effects of these practices on biodiversity, but the effectiveness of these actions depends both on which scale they are evaluated and the group of species they are addressed to. In Sweden, landscape restoration projects called ecoparks have being established with the aim of creating multipurpose forests which combine production, recreation and enhancement of natural values. The evaluation of different management regimes has been focused on several group of species, but little research has been done on wild bee communities in boreal forests. With a functional and multi-scale approach, this study aims to figure out whether and how different management regimes affect diversity patterns of wild bee communities and investigate if there are differences in species and functional composition between these management regimes. A pair of landscapes consisting of an ecopark and a conventionally managed production landscape were selected in the south and north of Sweden. Bees were sampled during three years in open and sun-exposed plots where local environmental variables were measured. There were no differences between management regimes. Instead, differences in inventory diversity, functional diversity and species assemblages were found between southern and northern regions. This study suggests that landscape could be playing an important role in the assemble of wild bee communities and highlights the potential of using a functional approach when assessing the effects of different management regimes on wild bee communities.
