研究领域

Biological invasions: The introduction of species into new environments has increasingly become an economically costly and environmentally disruptive phenomenon. Our research on invasions focuses on social insects (ants, bees and wasps) and primarily encompasses the following questions. (i) What factors control susceptibility to invasion? (ii) What accounts for how invasion impacts change in magnitude over time? (iii) Why do native species assemblages differ in their ability to recover following experimental invader removal? Pollination services: Declining pollinator populations threaten to compromise the integrity of pollination services in both agricultural and non-managed systems. Our research addresses this general issue from the following perspectives. (i) To what degree does land-use intensification affect pollinator assemblages? (ii) To what extent do pollinator declines compromise pollination services? (iii) How do non-native species interact with native pollinators, and when do these interactions negatively impact pollination services?
