Arthropod (per year, 2008-2017) and environmental data (climate, land use, land cover) from grasslands used in "Unravelling insect declines: can space replace time?", Biology Letters

To compare trends in arthropod species numbers between space and time, arthropod data from the sweep net samples (2008-2017) in grasslands were used. We tested whether trends over time are also found within single years (i.e. in space). The dataset contains, pooled per sampling year, arthropod individual numbers (Araneae, Coleoptera, Hemiptera, Orthoptera) and associated environmental data (climate, land use, land cover). This data is only to complement the publication "Unravelling insect declines: can space replace time?" by Blüthgen et al. in Biology Letters. Data are a combination of the yearly grassland arthropod data in dataset 25786, the LUI input data in dataset 25086, climate data (19007), and land cover data (26007).
