Restoration of invaded grasslands in a changing world: Impacts of invasive plants and climate change on ecosystem functioning

Advisor: Prof. Dr. Johannes Kollmann (TUM)

Biodiversity and ecosystem functioning (BEF) studies provide ample evidence that plant diversity controls the ecological functions and services provided by many ecosystems, and, thus, positively contribute to human welfare. Therefore, biodiversity and ecosystem functioning studies are crucial for understanding anthropogenic impacts on natural ecosystems and for predicting future scenarios, allowing scientists and stakeholders to adopt new strategies for reducing the risks of loosing ecosystem functions and services that are important for human wellbeing. Indeed, there are two main threats to ecosystem health and stability, i.e. habitat loss and invasive alien species (Millennium Ecosystem Assessment 2005; CBD 2010). Both threats can positively interact, thus amplifying anthropogenic impacts on ecosystems. Land transformation and the consequential destruction of habitats by human activities will negatively affect native species diversity, while making ecosystems less stable and less resistant to invasions. Then, invaded ecosystems will be modified by the impacts of alien species on native community dynamics. The effects of the invader on native species occurrence and abundance, community composition and ecosystems properties will, ultimately, favour further invasions.

Recent studies performed around the world have shown that climate changes might have a more drastic effect on species diversity and distribution, ecosystem stability and human wellbeing than invasive species. Furthermore, climate changes can increase the range of alien species distribution across regions or even continents. Ultimately, climate changes would favour invasion success by compromising native species diversity and increasing ecosystem susceptibility to invaders. Despite all the impacts on natural ecosystems resulting from anthropogenic activities, we can understand such scenarios as opportunities for building solid knowledge on how to cope with the challenges arising in a human-dominated world. In fact, more fundamental conclusions about the functioning of ecosystems might be reached by combining different levels and aspects of diversity with different stressors in experimental communities. Particularly, functions related to future scenarios of land transformation, habitat loss, invasions and climate changes. Therefore, it is imperative to design and to test new strategies for the restoration of invaded ecosystems in face of climate change scenarios.

The project investigates how different community compositions (e.g. by the manipulation of the relative abundances of dominant and subordinate species) can be applied to improve restoration success and the functioning of restored ecosystems, mainly related to soil nutrient dynamics and resistance to invasive species. For this, we perform experiments in climate chambers (TUMmesa) testing the effects of the competitive hierarchies of plants for the resistance of grassland communities to the impacts of the invasive species Solidago gigantea on the soil nutrients and on the native plants biomass production. The main focus here is to monitor and to evaluate the functioning of restored ecosystems. These investigations can support management plans for degraded and invaded sites, thus contributing to the reduction of invasive species prevalence and its impacts on grasslands ecosystem functioning, because the most important roles for the biological resistance of native communities seem to be performed by dominant species, i.e. the dominance hierarchy hypothesis.
