Global biodiversity is decreasing, but regional declines of native species are often outnumbered by newly established aliens. Thus, changes in biodiversity are complex and scale-dependent. With more than 40 000 species known from Germany alone, science depends on experts who can handle this enormous taxonomic and ecological knowledge.


We study how environmental variables and anthropogenic management affect the diversity of organisms such as plants, spiders, insects and birds. In many cases, the involved species fulfil important ecosystem functions and are themselves affected by global environmental change. We transfer knowledge and empathy for biodiversity through environmental education.
