Working groups overview

As new WGs are established, this page will provide an up-to-date overview, including each group’s focus, leadership, members, work plan, and key outputs.

Transient impacts of invasive species

Shifts between quiescence and impacts of non-native species : understanding invasion transitions

Group leader: Deepa Pureswaran

Number of members: 9

Period: Starting March 3, 2026

This Working Group explores why some non-native species remain quiescent for long periods before becoming damaging, and why other species initially cause impacts before transitioning to quiescence. By synthesizing knowledge across taxa and regions, the group aims to improve understanding of dynamic invasion impacts in terrestrial ecosystems.

Insects on trees

Biogeographic analysis of historical forest insect invasions and host associations

Group leader: Andrew M. Liebhold

Number of members: 6

Considerable variation exists among different regions in numbers of established non-native species. For example, many more European forest insects have invaded North America than North American species have invaded Europe. Here we seek to understand the reasons for these and other types of variation in rates of forest insect invasions among these world regions.
