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 and Master students in landscape ecology as well as studens of other disciplines of geosciences.

A winter visit to the Yamal tundra
Upon invitation by the government of the Yamal-Nenets autonomous district in the very north of Western Siberia, Norbert Hölzel and Ramona Fitz joint an international conference on “Preventing the dissemination of infectious animal diseases on climate change” held in the city of Salekhard at the polar circle from November 9th to 11th, 2016.
The conference topic was directly related to the first outbreak of Anthrax in Yamal since 1940 in July 2016 which killed 2.400 Reindeers and a 12 year old boy of a Nenets reindeer herder family. The Anthrax outbreak was most likely triggered by the extraordinary warm weather conditions in summer 2016 causing a deep melt down of permafrost soils that exposed persistent Anthrax spores. Russian and international experts from reindeer husbandry, veterinary science and grazing ecology discussed how such outbreaks can be controlled and mitigated under ongoing climate change.
Yamal is the last stronghold of reindeer husbandry worldwide with more than 14.000 indigenous people maintaining a nomadic life style, currently keeping ca. 750.000 Reindeers. During a helicopter excursion to the Tundra of the southern Yamal peninsula the conference participants were introduced to the peculiarities of regional reindeer husbandry and the nomadic life style of Nenets people.
Meeting in China on Conservation Measures for the Endangered Yellow-breasted Bunting
In 2015, member of our group had helped to reveal the catastrophic population collapse of what was once one of the most abundant bird species of Eurasia, the Yellow-breasted Bunting. At that time, we concluded that ongoing illegal persecution of the species for food was one of the main reasons of the decline.
From 2-4 November 2016, a workshop was organized in Guangzhou, China, by Birdlife International, Sun Yat Sen University and the Hongkong Birdwatching Society. It aimed to bring together representatives of all countries that host Yellow-breasted Buntings during the breeding season and in winter, from Russia and China to Myanmar and Thailand. Each country provided an update on current population trends and threats to the species. Much emphasis was put on a prioritization of conservation measures, such as better enforcement of laws against illegal trapping and awareness raising among wildlife consumers. A new wildlife law will be approved in 2017 in China and there are high hopes that it will give the Yellow-breasted Bunting a higher level of protection. Exciting collaborative projects on research and conservation involving multiple range states were also agreed.
A Special Issue of Biodiversity and Conservation on the ecology and conservation of the Palearctic steppes is now out, including eight publications of our Working Group - one new synthesis paper and several papers on results of the projects in Russia (SASCHA) and Kazakhstan (BALTRAK).

Coppiced woods – traditional socio-ecological systems with a high biodiversity value
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 theRSPBand the Danish BirdLife partnerDOF 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!
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.
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
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
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+"
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.
Starting from 2020, only seeds from local origin are allowed in meadow restoration projects in Germany’s open countryside. This concept is now supported by two studies we conducted together with colleagues form the Helmholtz-center for environmental research (UFZ), the University of Tübingen and the Technical University of Munich.

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".
