Ecology

What is the impact of invasive species on the original biodiversity of the habitats they invade? Why do invasions increase biodiversity in some cases and reduce it in others? Invasion processes, as they are known, are one of the core research interests of the world-renowned ecologist Tiffany Knight. The American environmental researcher focusses in particular on the interaction between plants, microorganisms, pollinators and herbivores. She uses a variety of methodological and theoretical approaches deriving from population biology and evolutionary research. A special feature of her research is that she studies these interactions across different ecosystems as well. Her work on the connections between fish populations in ponds and the stocks of plant-pollinating insects on land are seen as a breakthrough in biodiversity research. She discovered, for example, that plant pollinators tend to avoid ponds where there are no fish; instead, these ponds attract a larger number of dragonflies, which feed on insects. Knight’s task at Martin Luther University Halle-Wittenberg and the Helmholtz Centre for Environmental Research in Leipzig will be to create a focus for content generated by the various areas of ecological research, from molecular research to green corridors.
