Globale Veraenderungen und Biodiversitaet in Boeden

Description: GLOBIS untersucht die gegenwaertigen und zukuenftigen Wirkungen der globalen Klimaaenderungen auf die Biodiversitaet in europaeischen Waldboeden, sowie die Rueckwirkungen moeglicher Diversitaetsaenderungen auf oekosystemare Prozesse (Dekomposition; C und N Pools und Fluesse). Artendiversitaet, funktionelle Diversitaet und trophische Struktur werden analysiert. Zusammen mit Partnern aus England, Schweden, Frankreich und Griechenland werden die Untersuchungen entlang von zwei europaeischen Transekten durchgefuehrt.

  Title: Global Change and Biodiversity in Soils
  Description: Two central hypotheses will be testet: I) climate induced perturbation selects for species with reduced ability to carry out key functions; II) redundancy is needed to maintain key functions in perturbated environments. The measurements include both diversity related parameters (micro-, meso-, macrofauna; taxonomic and biochemical methods for microbial diversity) and functional parameters. The project will utilize the natural environmental variation by carrying out studies along 2 European transects, covering major gradients of temperature, moisture, deposition and management practices. By choosing sites, which have been and are still intensely used for studies on ecosystem function, GLOBIS aims at forming 'diversity links' to as well as between interdisciplinary European research projects (VAMOS, CORE, NIPHYS). This strategy will be combined with both field experiments, where relevant environmental conditions are controlled, and manipulation experiments in the laboratory to evaluate the importance of different factors. The research activities of GLOBIS are broken down into 3 work packages, which are further subdivided into tasks: WP 1 (Transect studies): The continental gradient approach provides essential data on the correlation between environmental conditions and diversity/function relationships. This experimental strategy incorporates a new decomposition experiment with litter-bags in climatically different ecosystems to allow temporal and spatial monitoring of soil biota as decomposition of selected organic matter substrates proceeds. The litterbag experiment will be complemented by an intense study on the functional implications of microbial diversity in soil and its relation to climate, resource input and management. These studies are carried out by isolation techniques (taxonomic approach) and fatty acid analyses (biochemical approach). WP 2 (Environmentally controlled conditions): Field experiments with environmentally controlled conditions (elevated temperature elevated and reduced moisture) aim at understanding and predicting the response of the belowground community to climate change. The studies will be carried out at the extreme edges of the GLOBIS transects (three sites in Sweden, one site in Greece) to cover most aspects of the environmental gradient. WP 3 'fine tuning' will be possible by testing hypotheses on the role of selected functional groups, functional diversity and trophic connectivity in manipulation experiments. A set of experiments with various experimentally communities will be established. They include both experiments with altered diversity of functional groups and altered diversity within functional groups. The benefit of GLOBIS will be a better understanding and predicting of the way in which biological diversity in soil regulates ecosystem function and how this will be altered under global usw. https://ufordat.uba.de/UFORDAT/pages/PublicRedirect.aspx?TYP=PR&DSNR=67037
