Eco-evolutionary dynamics of plant-insect food webs

Eco-evolutionary dynamics of plant-insect food webs

Abstract: Global change is reshaping biodiversity across scales — from the genetic makeup of populations to the composition of species in ecological communities. These cross-­scale changes often unleash an array of indirect effects that make it difficult to predict ensuing ecological and evolutionary responses due to the complex network of interactions species are usually embedded in. In this seminar, I will share a series of field and lab experiments with plant-insect food webs that seek to better understand the interconnected nature of biodiversity across scales. I will begin by showing how genetic variation within species can scale up to influence food-web structure and species coexistence. I will then discuss how the diversity of species in a community can feedback to shape genetic and phenotypic variation in interacting populations. Throughout, I will argue that understanding these eco-evolutionary processes is critical for predicting how biodiversity will be reorganized by environmental change.

IGB Colloquia open up!

IGB strives to facilitate and accelerate the exchange of knowledge and ideas within and also outside of IGB. One element contributing to inter- and transdisciplinary exchange, and more (scientific) cooperation and innovation, is to open up IGB Colloquia to an interested external audience from science (other research institutes, universities, laboratories) as well as practice (i.e. conservationists, freshwater/land-use managers, authorities, associations). If you would like to join this IGB Colloquium as a guest, we ask you to register until the morning of the colloquium 10 o'clock the latest. After we have checked your registration, you will receive the participation link.
