The effect of landscape heterogeneity on biodiversity and ecosystem services in agricultural landscape


Balancing Agroecosystem Services In Landscape (BASIL) financed by BMBF (2015 – 2018)

BiodivERsA/FACCE-JPI 2013-2014 Joint Call on "Promoting synergies and reducing trade-offs between food supply, biodiversity and ecosystem services"

Supervising team:

Prof. Dr. Jasmin Joshi (Hochschule für Technik, Rapperswil CH)

Prof. Dr. Christoph Scherber (Westfälische Wilhelms-Universität, Münster DE)

Dr. Karin Pirhofer-Walzl (Freie Universität, Berlin DE)

Biodiversity has the potential to buffer ecosystems against change and stabilise ecosystem functions and services. However, the suitable level of biodiversity to maximize ecosystem services in agricultural landscapes is not yet known and quantified. In the BASIL project, we aim at understanding the importance of diversity from the plot to the agricultural landscape scale evaluating intensively managed sites and adjacent natural habitats for abiotic and biotic characteristics, related functions and their contribution to ecosystem services.

My analyses focus on crop production, nutrient supply and pest control along transects from natural landscape elements (in-field ponds and hedgerows) into winter wheat fields in the Quillow catchment (Brandenburg). I established phytometer plots of a winter wheat variety at all transect points to compare for crop and vegetation traits, soil physical, chemical and biological traits as well as potential crop pests and their biological controllers.

I am working on agricultural weeds, soil mesofauna (Collembola, Acari), earthworms, ground-dwelling arthropods (beetles and spiders) and leaf and seed pathogens of winter wheat. The diversity and distribution of those communities will be evaluated in the context of measured rates, i.e. decomposition rates, predation rates of seeds, herbivory rates among others to gain more insights on the importance of landscape heterogeneity for the presented ecosystem services.
