Natural and anthropogenic determinants of biodiversity of grasslands in the Swiss Alps
This thesis studies natural and anthropogenic determinants of grassland biodiversity in the Swiss Alps at the levels of plant communities within a landscape (Chapter 2), species diversity within plant communities (Chapter 2 and 3), biological interactions between plants and herbivores and pathogens...
