The files 04_SEMData_2008 and 04_SEMData_2009 include compiled information used for structural equation modeling.
PlotID --> plot specific ID
Region --> One of three regions in Germany in which plot is located (SEM was conducted for each region separately)
Fertilization --> intensity of fertilization, averaged over three years and standardized per region
Grazing --> intensity of grazing, averaged over three years and standardized per region
Mowing --> intensity of mowing, averaged over three years and standardized per region
Time_after_mowing --> Number of days between last mowing event and sampling in the year of sampling
Plant_SpeciesRichness --> Number of vascular plant species
Plant_biomass --> Plant biomass [g dry weight]
Herbivore_SpeciesRichness --> Number of herbivorous arthropod species
Predator_SpeciesRichness --> Number of arthropod predator species
Herbivore_biomass --> Overall biomass [mg] of herbivore species
Predator_biomass --> Overaall biomass [mg] of predator species
