Butterfly assemblages in residential gardens are driven by species’ habitat preference and mobility

摘要: Understanding the factors contributing to maintaining biodiversity is crucial mitigate impact of anthropogenic disturbances. Representing large proportions green area in highly modified landscapes, residential gardens are often seen as local habitats that can contribute larger networks suitable environments at landscape scale. We investigated context on butterfly communities observed gardens, taking into account garden characteristics, land-use types and presence linear features surrounding landscape. examined how species traits affected butterflies’ response habitat quality. performed a cross-scale study, based citizen science data documenting composition abundance 920 across France. effect quality, different length elements measured three scales within Species were grouped according their preference mobility. Urbanization negatively total richness each group. This was related declining quality reduced The magnitude this effect, however, correlated with mobility, trait preference. spatial scale which best explained variation changed species’ study highlights importance preserving high altered landscapes considering mobility when assessing communities.
