GrassPlot v. 2.00 : first update on the database of multi-scale plant diversity in Palaearctic grasslands
Abstract: GrassPlot is a collaborative vegetation-plot database organised by the Eurasian Dry Grassland Group (EDGG) and listed in the Global Index of Vegetation-Plot Databases (GIVD ID EU-00-003). Following a previous Long Database Report (Dengler et al. 2018, Phyto- coenologia 48, 331–347), we provide here the first update on content and functionality of GrassPlot. The current version (GrassPlot v. 2.00) contains a total of 190,673 plots of different grain sizes across 28,171 independent plots, with 4,654 nested-plot series including at least four grain sizes. The database has improved its content as well as its functionality, including addition and harmonization of header data (land use,…
Landscape and habitat filters jointly drive richness and abundance ofspecialist plants in terrestrial grassland islands
Land use changes have resulted in the loss and isolation of semi-natural habitats worldwide. In intensively used agricultural landscapes the remnants of natural flora only persist in small habitat islands embedded in a hostile matrix (Deák et al. 2016a). Species composition of small habitat islands is substantially influenced by habitat and landscape filters through persistence and dispersal traits of plant species. Due the interaction of factors acting in different spatial scales, vegetation of habitats islands can be evaluated by a complex approach considering multiple spatial scales. We sampled grassland specialist plant species, local environmental factors (habitat filter) and the lands…
Effects of mowing frequency on grassland flora and fauna: implications for the conservation of semi-natural grasslands in Europe
To maintain the high biodiversity and preserve the conservation value of semi-natural grasslands, management like grazing or mowing is necessary. Given the limited resources available for management, and few remaining areas, the best management method and intensity should be used. However, the evaluation and comparison of effects of different management intensities on a larger scale is often challenging, as most studies have a limited scope (e.g. only investigating effects in one grassland or for one type of organism). In view of this, we used meta-analysis methods to explore effects of different mowing intensities on biodiversity on a European scale, to reach more robust conclusions. We in…
