Recent studies suggest that species distribution models (SDMs) based on fine‐scale climate data may provide markedly different estimates of climate‐change impacts than coarse‐scale models. However, these studies disagree in their conclusions of how scale influences projected species distributions. In rugged terrain, coarse‐scale climate grids may not capture topographically …

We test to what extent mean environmental condi- tions and environmental heterogeneity are related to species richness in a regular geographical grid system (UTM) of 10 km ∞ 10 km in the NE Iberian Peninsula (i.e. Catalonia, ca. 31 900 km2). Species richness of each UTM quadrat was estimated by compiling a large database (more than a million records) from bibliographic …

Grazing intensity influenced both fine- and coarse-scale plant community patterns and created different, but stable, plant community patch sizes over time. Based on these results, the ecological cost of inactivity in managing grasslands may have profound consequences on plant community stability and the wildlife that depend on them.
