Abundance and taxonomic data of spiders (family, genus and species) collected with pitfall traps from temperate forest stands from Lower Saxony, Germany. Five forest stand types were studied (Douglas fir monoculture, European beech/Douglas fir mixture, European beech monoculture, European beech/Norway spruce mixture, Norway spruce monoculture) at seven different sites, four in southern (site 1-4) and three (5,7,8) in northern Lower Saxony, Germany. Eight pitfall traps were set at each of the 35 plots and the material was collected every three weeks starting from 03.09.2019.
Abundance and taxonomic data of carabids collected with pitfall traps from temperate forest stands from Lower Saxony, Germany. Five forest stand types were studied (Douglas fir monoculture, European beech/Douglas fir mixture, European beech monoculture, European beech/Norway spruce mixture, Norway spruce monoculture) at eight different sites, four in southern (site 1-4) and three (5-8) in northern Lower Saxony, Germany. Twelve pitfall traps were set at each of the 40 plots and the material was collected every three weeks starting from 03.09.2019.
Abundance and taxonomic data of arthropods collected with pitfall traps from temperate forest stands from Lower Saxony, Germany. Five forest stand types were studied (Douglas fir monoculture, European beech/Douglas fir mixture, European beech monoculture, European beech/Norway spruce mixture, Norway spruce monoculture) at seven different sites, four in southern (site 1-4) and three (5,7,8) in northern Lower Saxony, Germany. Twelve pitfall traps were set at each of the 35 plots and the material was collected every three weeks starting from 03.09.2019
The dataset contains calibrated isotopic data (∆13C, ∆15N) and relative biomasses of spiders and ground beetles, sampled in 2019 in Lower Saxony, Germany, within the RTG 2300 project "Enrichment of European beech forests with conifers". Arthropods were sampled with pitfall traps and identified to species level by Kriegel et al (2021) and Matevski and Schuldt (2023). Natural abundance isotopic ratios (δ13C, δ15N) were determined by the Centre for Stable Isotope Research Analysis at the University of Göttingen and thereafter calibrated with leaf litter isotopic ratios. Calibrated isotopic values (∆) were used to calculate multidimenional isotopic metrics, which were compared between different stand types and regions. The stand types were Douglas fir, beech-Douglas fir, beech, beech-spruce and spruce.
