Insects are many, important and diverse. To understand insect diversity, we need to understand both the environmental determinants of insect diversity and abundances, the biotic interactions between insects and other organisms (including humans), and the repercussions in terms of ecosystem functioning. To understand current biodiversity, we also need to understand its evolutionary history – to predict its evolutionary future. We aim for interdisciplinary approaches to understanding environmental change and human-nature relationships. As particular strengths we build on participatory approaches involving distributed experiments and collaborations well beyond traditional academia.
