GLiTRS will build a global threat-response model, integrating many lines of evidence from macroecology, meta-analysis and structured expert elicitation. We will quantify how insect biodiversity changes in response to anthropogenic pressures, how the response varies in space, by functional traits and according to the biodiversity metric used, as well as how these changes affect ecosystems. There are four analytical Work Packages and a further Work Package for Impact which you can read more about below.
