Butterflies 2008

Original data comes from a project which takes or took place as part of the DFG priority program "Exploratories for large-scale and long-term functional biodiversity research". The data is stored together with descriptive metadata, in combination called a dataset, in the project repository (https://www.bexis.uni-jena.de). Species information was extracted from that original dataset. The second paragraph is part of the metadata of the original dataset. Specialisation, abundance and diversity of flower visitors is compared across grasslands along a gradient of land use intensity. We focus on resource-based mechanisms that may determine flower visiting insect communities in different habitats. We will analyze flower visitor rates of pollinators in order to measure possible variation between differently used sites. Moreover, we will characterize the degree of specialisation on species and community level (pollinator networks; Blüthgen et al. 2007)
