Can linear transportation infrastructure verges constitute a habitat and/or a corridor for insects in temperate landscapes? A systematic review

Table 2 Description of the PECO/PICO items of the primary question

Population	All insect species and communities of the temperate climatic zone^a
Exposure	LTI verges (road, railway, power line and pipeline verges and waterway banks)
Intervention	Management practices or human-induced disturbances of LTI verges
Comparator	Both temporal and spatial comparators, including but not restricted to: Temporal comparators Ecosystem present before infrastructure construction Verge before management intervention Spatial comparators Nearby habitats away from LTIs Unmanaged verges or verges managed with a different practice
Outcome	All outcomes relating to corridor or habitat assessment, including but not restricted to, species dispersal, species richness, abundance and community composition

^aThe Köppen–Geiger Climate Classification was used to identify articles with a study zone in the temperate climate. As the funders of the study are interested in western Europe, the Cfa, Cfb, Cfc, Csa, Csb and Csc temperate zones were included in the scope of our study.
