Effect of connectivity between restoration meadows on invertebrates with contrasting dispersal abilities

摘要: Schemes to restore farmland biodiversity are often implemented at field scale whereas landscape factors not considered. In a grassland dominated region in Switzerland, we tested whether the factor habitat connectivity could possibly increase effectiveness of an agri-environment scheme for meadows. We investigated two indicator groups with contrasting dispersal abilities, land snails and orthopterans (grasshoppers). 27 extensively managed meadows grouped into nine blocks. Each block consisted three differing structural use history: one meadow represented long-term, semi-naturally calcareous that was considered as potential source habitat. The other were restoration meadows, created 4–6 years ago. One these adjacent meadow, isolated from it. found significantly higher species diversity both invertebrate compared Communities taxa more similar connected than bad dispersers negatively affected by isolation, but good unaffected. With respect individual occurrences, however, even isolation. conclude habitats is important increasing success communities, particularly those containing limited abilities.
