Resumen
Diversity of plants in agricultural landscapes is decreasing continually until today and this has cascading effects on ecosystem services and persistence of rare plants. Plant diversity, however, is not equally distributed among different habitat types. On a larger scale differences among habitats can contribute strongly to the global diversity of an agro-ecosystem. Landscape context and intensity of agriculture can also have effects on diversity. In this work, we present a thorough analysis of β-diversity in Mediterranean vineyard ecosystems, showing the effect of geology based landscape units for the outcome of β-diversity as well as management intensity for β-diversity of threatened plants. The change in β-diversity according to landscape context emphasizes the importance of landscape heterogeneity and vineyard habitats for local plant diversity. Low intensity agriculture was identified to maintain the highest levels of plant α- and β-diversity and to promote persistence of rare plants.
