CV / Scientific Career

1982-89

Studies of biology at the universities of Marburg and Bayreuth, with a major in animal and plant ecology and a minor in biogeography.

1989 - 1993

PhD student at the chair of Chemical Ecology, University of Bayreuth (topic: Canthariphilous gnats (Diptera: Ceratopogonidae)); fellowship of the "Studienstiftung des Deutschen Volkes"

Research scientist at the Department of Community Ecology, UFZ


Research interests

My recent work takes place in different fields:

1. Research and Observation

TERENO project (Terrestrial Environmental Observatories): As an animal ecologist I am dealing with insects and birds which are regularly surveyed within the German long-term project TERENO . I am responsible for the mentioned animal groups at the UFZ TERENO observatory Harz / Central German Lowland. Linking to ecosystem services, we are concentrating on pollinators (bees, hoverflies, butterflies) and analyze the impact of landscape structure land use change on these insect communities. This is supported by studies on pollination success in selected plants. Birds as integrating indicators at the landscape scale are the second group for tackling landscape structure effects and land use change. This is approached by e.g. investigating the importance of taxonomic diversity indices to discover differences in communities.

Effects of different plant origin on related insect communities: using non-regional seeds for renaturation and restoration purposes may disturb the synchronization with specialized insects feeding on these plants, as the phenology of a given species in different regions differs. In common garden experiments we investigate the effects of different seed origin on the local insect fauna.   

Former studies: (a) patterns of alpha and beta diversity of the fauna of cabbage plants (Brassicaceae); (b) biogeographical patterns of host use and species associations of phytophagous insects and their parasitoids using the example of thistles (Cynaroideae) and their fruit fly fauna (Diptera: Tephritidae) in Europe; (c) biological invasions, especially the colonisation of new (alien) host plants by phytophages and the characteristics of the host plant responsible for the colonisation success.

2. Measurement standardisation at Long-Term Ecological Research (LTER) sites

Since 2006 I am involved in organising the German network of Long-Term Ecological Research LTER-D and in the development of criteria for LTER sites all over Europe in the network LTER-Europe . The standardisation of parameters and methods is one of the big challenges for LTER sites worldwide. As one of two leads of the LTER-Europe expert panel Expert panel Standardisation & Technology I am in charge of the standardisation issue. This work is supported by the life+ project EnvEurope , (2010-2013) the FP7 project ExpeER (2010-2015) and the Horizon 2020 project eLTER. The web tool ECOPAR is an important outcome of this work. It is an interactive compilation of measurables relevant for ecological studies based on the ecological integrity concept. Related to this is the work on the thesaurus (standardised vocabulary) EnvThes and the metadata repository DEIMS (Drupal Ecological Information Management System).  

3. Data management and DOI for data sets

This issue becomes more and more important especially for large institutions generating lots of data. Especially in terms of finding and reuse of data and the open data approach within the Helmholtz association quality assurance, persistent storing, metadata documentation and finally the assignment of DOI (Digital Object Identifier) to data sets is nowadays an expected workflow. Since 2012 I am contributing to this task at the UFZ by co-organising the quality control process of device-generated data and a special focus on biodiversity data generated at our department. Biodiversity data are processed with the information system BExIS (DFG funded project aiming to provide a generic tool for biodiversity data).
