Flying insect biomass is negatively associated with urban cover in surrounding landscapes

Landscape-level drivers of flying insect biomass

This repository (R project) contains all scripts necessary to run the ecological/statistical analyses from the study "Flying insect biomass is negatively associated with urban cover in surrounding landscapes" (Svenningsen et al. 2022, DOI: https://onlinelibrary.wiley.com/doi/pdf/10.1111/ddi.13532).

The data were collected in June 2018 as part of the citizen science project InsectMobile ("Insektmobilen") at the Natural History Museum of Denmark and at iDiv in Germany during June-July 2018.

• Data: data (e.g. the proportional land cover and land use data, flying insect biomass etc. for each buffer zone) used in the analyses is deposited in Dryad: https://doi.org/10.5061/dryad.547d7wm9f

Description of the sub directories for data processing

• reports: a step-wise list of scripts (01_, 02_ etc.) used for processing and analysing the data
• plots: figures generated by the scripts and other plots not used in the manuscript

Statistical analyses and modelling

Landscape-level effects on flying insect biomass was modelled with linear mixed-effects models at the buffer size with the most pronounced effect size.
