Congruent direction but different magnitude of biodiversity response to land-use intensification in space and time Open
Land-use intensification is considered a major driver of biodiversity loss. However, most evidence for land-use effects come from comparing biodiversity in areas differing in current land-use intensity. The robustness of such space-for-tim…

Direct and Indirect Effects of Ivermectin on Phytophagous, Frugivorous and Parasitoid Insects Open
Ivermectin, an anthelmintic used in livestock, is excreted in faeces and can therefore affect non-target organisms. While its effects on coprophagous insects have been well studied, recent research suggests that it can be taken up by plant…

Advancing the quantification of land-use intensity in forests: the ForMIX index combining tree species composition, tree removal, deadwood availability, and stand maturity Open
Many forests have a long history of human land use, which relates to species communities and ecosystem processes, making robust and quantitative measures of land-use intensity in forests desirable. We here introduce the ForMIX (Forest Mana…
