Relative importance of current and past landscape structure and local habitat conditions for plant species richness in dry grassland-like forest openings.

In fragmented landscapes, plant species richness may depend not only on local habitat conditions but also on landscape structure. In addition, both present and past landscape structure may be important for species richness. There are, however, only a few studies that have investigated the relative i...
