to the Biodiversity and Ecosystem Research Group

The Biodiversity and Ecosystem Research Group is part of the Institute of Landscape Ecology (ILÖK) of the University of Münster. We study the structure, function and change of terrestrial ecosystems by using soil and vegetation as integrative key features in landscape ecology. We offer a broad range of courses in vegetation science and physical geography that addresses Bachelor, Master and Diploma students in landscape ecology as well as studens of other disciplines of geosciences.

'North Sea Region Climate Change Assessment' published as book

Hoelzel 2016 North Sea Region Climate Change Assessment
© SpringerOpen

Within the 'North Sea Region Climate Change Assessment' (NOSCCA) Prof. Norbert Hölzel together with Prof. Thomas Hickler (Senckenberg Biodiversity and Climate Research Centre (BiK-F) and Goethe University Frankfurt) and Prof. Lars Kutzbach (CEN, University Hamburg) as Lead Authors composed a chapter on Environmental impacts of climate change on terrestrial ecosystems in the North Sea Region.
Initiated by the Institute of Coastal Research of the Helmholtz-Zentrum Geesthacht in Germany, the NOSCAA Report is a comprehensive climate change assessment for the Greater North Sea region and adjacent land areas. Recent and future climate changes and their impacts are discussed for the North Sea, rivers, lakes and atmosphere as well as terrestrial ecosystems and socio-economic aspects, for example coastal protection or fisheries. NOSCCA is writen by over thirty Lead Authors and numerous Contributing Authors under the overview of an international Scientific Steering Committee (SSC) and with an independent review. The report is now published as book with Open Access by Springer.

The biodiversity of open landscapes has been declining strongly over the past decades in Central Europe. Agricultural intensification and farmland abandonment are among the most prominent reasons behind this. Changes in forest management are now surfacing as an additional cause: a transition from light, open forests to tall, dense stands with a cooler microclimate has resulted in population losses of many open-habitat plants and animals during the past decades.

The management of forests with a short cutting cycle, such as coppiced woods, has ceased now over most of Central Europe. To document the value of this rather sustainable forest management for biodiversity, two BSc-students of our group are currently quantifying the abundance and distribution of birds, butterflies and moths in one of the few remaining large areas of coppiced woods in Germany, the ‘Hauberge’ near Haiger in the state of Hesse. A contiguous area of 1,800 ha oak-birch-forest is managed there by village communities in a very traditional way, mostly for firewood. Stands are cut down patchily at an age of 18-20 years, which results in a rich mosaic of forest regrowth of young age classes. First results suggest that the area is of outstanding importance for long distance migrants, a group of birds that has declined strongly. The forests also appear to be the last strongholds of a number of butterflies and moths in Western Germany.

Citizen science online databases – how useful are they for monitoring population trends?

Monitoring of animal and plant population trends is important to identify declining species that can then be prioritized for conservation actions. Standardized, country-wide monitoring schemes are expensive, and need a large number of skilled volunteers to participate. However, with the advent of mobile technology, more and more people report casual observations of birds and other taxa online. Databases such as ‘ornitho’ or ‘eBird’ already store millions of records. The huge potential of these repositories for research and conservation has been recognized repeatedly, e.g. for explaining climate-change related phenology shifts or changes in the routes of migratory animals. If the mass of of ‘citizen scientists’ records is also useful to understand whether populations are increasing or decreasing was however unclear.

Using a country-wide database for birds, Johannes Kamp and colleagues from the RSPB and the Danish BirdLife partner DOF examined if bird population trends derived from online recording matched those from a more standardized monitoring scheme. In a recent paper in Diversity & Distributions [doi: 10.1111/ddi.12463/full], they report that declines in many bird species detected by standardized monitoring were not picked up by the unstructured online databases, suggesting that the latter are no easy substitute for cost-intensive structured monitoring. This is most likely explained by observer behaviour – encouraging birdwatchers to report all species in an area (and not only rare or interesting ones) will increase the usefulness of the data for many research questions.

The Tea Decomposition Project - It´s Tea Time!

© Ika Djukic

Since beginning of June the ILÖK takes part in the worldwide project "TeaComposition". This project is led by the Ecosystem Research and Environmental Information Management Working Group of the Federal Environment Agency in Vienna, and aims at analysing long term litter decomposition dynamics in different habitat types.

Main focus will be the assessment of carbon losses and storage in litter and their key drivers under recent and predicted climatic scenarios worldwide. The instalation of tea bags as well as the subsequent analyses will be performed in cooperation of the working groups Soil Ecology and Land use and Biodiversity and Ecosystem Research within the Biodiversity Exploratories.

Two successful doctorates at once!

We congratulate our PhD students Kristin Gilhaus and Immo Kämpf to their successful thesis defenses. At the same day as Elisa Fleischer (Climatology group) they defended their theses with the titles “Grassland management by year-round grazing – opportunities and constraints“ and “Effects of Land-use Change on Agroecosystems of Western Siberia”.

University newspaper reports on urban ecological research

Forschung an städtischen Grünlandflächen

The current issue of the wissen|leben (Issue 2, April 2016 (German); german article  here), the official newspaper of WWU Münster, reports on biodiversity research by Valentin H. Klaus and his students. In various bachelor and master theses, the researchers assessed plant diversity and environmental conditions in parks and urban grasslands in Münster. Additionally, at the lake Aasee, experimental plots were installed to floristically enrich the established grassland vegetation (Publication in the Project "Urban Ecological Research").

Teams are already standing on their starting blocks for the Field Work Season 2016

Auf zur Feldsaison 2016

Fieldteams of the projects STOICHIO and  ESCAPE of the Biodiversity-Exploratories will take off for their last field season of the current project phase.

Both teams will conduct vegetation relevés and collect biomass samples on grassland plots  in the National Park Hainich-Dün (Thuringia) and its surroundings. During this field work phase we will complete data sets regarding nutrient stoichiometry, biodiversity, productivity, disturbance and resilience of grasslands along a land use gradient.

New edition of the "Davert Depesche+"

Titelblatt Davert Depesche+

Recently and within the project "Fit for Climate Change", the new edition of the "Davert Depesche+" brochure has been released. The University's role as scientific supervisor of the project is displayed vividly, a spring flower is presented and to "natural scientists" are being portrayed.

This edition also counts with the second quartal's programme and is completed by a searching game for children. The brochure is released quarterly and is on display in many locations in the South of Münster and in the Institute for Landscape Ecology. Additionally, a german version may be downloaded here.

Asynchrony plays a greater role in stability than diversity alone

The stability of animal or plant communities under consideration of external factors does not only depend on biodiversity. Most influencing factor is the asynchrony of populations: the greater the temporal variation of the development of different species within one ecosystem, the higher its stability. These results were obtained by scientists of our groupunder the leadership of colleagues of the TU München and the TU Darmstadt and have now been published in "Nature Communications".
