Insects on trees

Biogeographic analysis of historical forest insect invasions and host associations
Insects on trees
It was inspiring to collaborate with such a diverse team — I learned as much from the economists and data scientists as I did from fellow ecologists.

About & focus

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.

We test hypotheses that both native and non-native species richness of tree herbivores are related to tree species range area and that native and non-native insect herbivore richness are correlated. We will also consider other characteristics of tree species (e.g., growth characteristics) as correlates of native and non-native herbivore diversity.

We explore biogeographical patterns relative to invasions. Specifically, we study the diversity of both native and non-native insect herbivores that use different tree species in Europe and North America as hosts and explore the possible drivers of variation among tree species and among regions.
