Abstract

The objective of our investigations was to quantify the impact of landscape patterns and species community structure (ratio of generalists to specialists) on species richness. Therefore, we built a model which calculated the effects of several hypothetical landscapes on the diversity at different scales (alpha, beta-, gamma-diversity). The results showed that there was always a significant effect of landscape patterns on species richness. However, depending on the species community structure, we observed different strong relationships between spatial patterns and species diversity.

Additionally, floristic and faunistic data of empirical studies were analysed regarding species number in each land use, the habitat specificity of each species, and the proportions of generalists and specialists in each land use. Simulations with these data showed that the impact of landscape aggregation and composition vary depending on the community structure and the species number in each habitat type.

These interdisciplinary investigations of the relationship between landscape patterns and species richness emphasise the necessity of combining experts' opinion to reproduce the complex interactions in nature.
