human-induced decline in global biodiversity across all trophic levels
reduces the ability of ecosystems to maintain key ecosystem
functions. Extirpation of vertebrates and invertebrates from
ecosystems, i.e., defaunation, alters the structure, composition, and
strength of interactions within and between trophic levels and
therefore the functioning of the ecosystem. Hence, defaunation can
weaken interactions such as those between the aboveground
invertebrate and belowground decomposer communities, or between the
soil arthropod community and their physicochemical environment.
Moreover, defaunation often operates in a size-selective, non-random
manner, with larger species disappearing before smaller-sized species
that all have different impacts on how the ecosystem responds to
these losses. Hence, the big question is: how does the loss of
vertebrates and invertebrates affect ecosystem processes and
functioning in grassland ecosystems? I will try to provide answers to this question based on research I conducted in many different
ecosystems across the globe over the past 20 years.</span><br></p>

Risch <span style="font-weight:normal">is a theoretical and applied ecologist studying how global change, mainly loss of vertebrate and invertebrate herbivores and eutrophication, affect the overall biodiversity, ecosystem functioning and above-belowground interactions. Risch published over 130 papers in scientific journals, but also repeatedly published for the general public. For her research, Risch often works in international networks, demonstrating her talent for bringing together and leading colleagues from diverse backgrounds. Risch holds a master's degree in biology from ETH Zurich and in forestry from Michigan Technological University, USA. She habilitated as a private lecturer at ETH Zurich. At WSL, she supervised numerous master's students, doctoral students, and PostDocs.</span></p><p style="margin-bottom:0.21cm;line-height:19.5px;direction:ltr">
