Insect species richness and biomass in grasslands - R-code

This zip-file contains data and R-Scripts to reproduce model results as shown in in the article "Metabarcoding of grassland insects reveals effectiveness of site-specific agri-environmental measures" by Bernd Panassiti, Sebastian Wolfrum, Sabine Birnbeck, Johannes Burmeister, Annette Freibauer, Jerome Moriniere, and Roswitha Walter. The dataset provided as a .RData-file contains insect and biomass data. The dataset is a result of the project "Evaluation of agri-environmental measures on insect diversity and biomass" carried out by the Bavarian State Research Center for Agriculture (LfL) during 2019-2022. Insect data was collected using Malaise traps in 4 grassland regions in Bavaria, Germany, during 3 sample periods in 2019 (regions Bavarian Forest, eastern Allgäu) and 2020 (regions (Chiemgau uplands, Upper Palatinate Forest). Insect data comprises the species richness of 9 insect groups: Total number of insect species Coleoptera Diptera Hymenoptera Lepidoptera Hemiptera Syrphidae (hover flies) Apiformes (wild bees and honeybees) Papilionoidea (butterflies)
