Plant functional group composition and large-scale species richness in European agricultural landscapes

摘要: Question: Which are the plant functional groups responding most clearly to agricultural disturbances? relative roles of habitat availability, landscape configuration and land use intensity in affecting composition diversity vascular plants landscapes? Location: 25 areas seven European countries. Methods: We examined species richness abundance 4 km × study sites. The group classification was derived from BIOLFLOR database. Factorial decomposition applied. Results: Natural availability low supported perennials, sedges, pteridophytes high nature quality indicator species. clonal species, C S strategists also correlated with area. An increasing density field edges explained a decrease an increase annual graminoids. Intensive agriculture enhanced annuals Conclusions: Habitat patch main drivers landscapes. Linear elements do not compensate for loss habitats, as they mostly support disturbance tolerant generalist In order conserve landscapes, protection enlargement existing patches (semi-) natural habitats appears be more effective than relying on rescue effect linear elements. This should done combination appropriate management techniques limit agrochemicals fields.
