Evolutionary ecology of above-below-ground plant-animal interaction

Mechanistic Community Ecology, Soil Ecology

Which biotic and abiotic factors drive variation in species interactions remains a central question in ecology. In our lab we take advantage of natural variation in species interaction generated by ecological gradients, and we use different approaches, including field common gardens, behavioral assays, chemical and phylogenetic analyses to address this question. By studying multitrophic interactions in natural settings we aim at harnessing the ecological and evolutionary mechanisms of community assembly, and ultimately, we hope to use this fundamental knowledge for targeted application related to crop production and biological control of insect pests.
