Host repertoires and changing insect–plant interactions

1. One of the main challenges faced by ecologists today is to understand and predict how species interactions will respond current environmental change. It likely that these changes have a stronger effect on phylogenetic lineages depend intimate specialised ecological interactions, such as most herbivorous insects. 2. In this review, we highlight aspects consider are fundamental for understanding change over time. We start reviewing terminology conclude commonly used terms undesired connotations with regard what know about hosts acquired lost 3. Based that, suggest host repertoire better term describe use multiple than range or diet breadth, both which fail capture often non-contiguous tend emphasise total number hosts, while ignoring identity. 4. Another important issue differentiation between realised repertoires, where latter set actually in nature, whereas first includes all can potentially be species. show characterisation key insect–plant opportunities instigated
