Studies of historical ecology are problematic because they depend on the ability to aggregate and filter relevant historical data from a wide and diverse range of sources. In the Biodiversity Virtual e-Laboratory (BioVeL) project we developed semi-automated data access and analysis services (so-called workflows). These workflows can be executed from the BioVeL portal (https://portal.biovel.eu/) and allow researchers to retrieve, integrate, clean, and refine species occurrence records as well as associated quantitative information (e.g. biomass) over large taxonomic, spatial, and temporal scales. We used the workflow to integrate data sets from several national biodiversity inventories conducted along the Swedish West coast and generated comparable data sets for analyzing the accumulated effects of long-term anthropogenic pressures on marine biodiversity in Sweden. Our results show clear indications that the biological community structure on the sea floor has changed dramatically over the last seven decades in the region. The talk will explain the relevance of the scientific results for the development of realistic conservation targets, and discuss the potential of biodiversity data services and workflow tools for ecosystem research.
