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

摘要: Background : The role of linear transportation infrastructures (roads, railways, oil and gas pipelines, power lines, rivers canals) in fragmenting natural habitats is fully acknowledged. Up to now, the potential verges (road railway embankments, strips grass under lines or above buried waterway banks) as habitat corridor for biodiversity, remains controversial. In a context decreasing habitats, opportunities anthropogenic areas contributing wildlife conservation have be considered. present paper first synthesis evidence about infrastructure and/or insects temperate landscapes. Methods A systematic literature survey was made using two online publication databases, search engine by sending call subject experts. Identified articles were successively screened relevance on titles, abstracts full texts criteria detailed an priori protocol. We then used six specific questions categorize critically appraise retained studies. These encompassed corridors insects, effects management landscape these potentialities. user-friendly database created sort studies with low medium susceptibility bias. synthesize results each question narrative synthesis. Finally, that met meta-analysis requirements quantitative synthesis. Results Our searches identified 64,206 articles. After critical appraisal, 91 reported 104 included our review. Almost all them had “control-impact” design, only “before-after-control-impact” one study “before-after” design. some cases, artificialization lowered insect biodiversity while vegetation restoration moderate positive effect; trend remained unclear mowing/grazing practices. Urbanization agriculture surroundings tended lower hosted verges, forested promote it. No dealt influence surrounding dispersal along verge. small number compared away from infrastructures, together inconsistencies their results, prevented us drawing conclusions. Meta-analyses performed 709 cases 34 primary vs. other habitats. Overall species richness did not differ between LTI Globally, abundance seemed higher than result driven pollinators consumers non-highway road roads. Conclusions major knowledge gap regarding has been identified. Thus, we encourage more research this topic. Infrastructure practitioners could benefit certain taxa impact practices richness.
