Early detection of GPP-related regime shifts

The invasion by Acacia in Portugal is a striking example of how exotic plant species can threaten native ecosystems. In the 20th century, the Long-leaved Wattle (Acacia longifolia), which is native to Australia, was planted along the Portuguese coast to stabilize dunes. Since then, the yellow flowering shrub has become invasive, and it is altering water and nutrient cycling with negative effects for the native species. Scientists from the Universities of Münster, Hamburg, Freiburg and Bielefeld show for the first time how to produce high-accurate maps of the wattle including its impact on nutrient cycling in a Mediterranean dune ecosystem. To this end, the team used high-resolution airborne sensor data. The study is published in the journal “Remote Sensing of Environment”

Non-lecture period means field-trip time at the Geographical Institutes of the University of Münster. Thus, a group of 16 geographers and landscape ecologists under the guidance of Dr. Andreas Malkus and Christoph Nothelfer went on a scientific excursion to Nepal end of February. Inter alia a trekking tour through the Himalaya mountains and a multi-day stay in the bustling capital Kathmandu are planned.

To share their experiences, the group arranged a blog. Find out more...

Conference "Insect declines"

© NABU

Over the past 27 years, insects biomass in parts of Northern Germany has declined by 75%. The consequences for the environment, for wildlife and humans are far-reaching. Therefore, together with the NABU (Nature And Biodiversity Conservation Union) the Institute of Landscape Ecology of the University of Münster invited to the symposium "Insect declines: State of Knowledge - Research - Countermeasures" on February, 17th 2018. Experts from science, agriculture and nature conservation discussed the current situation, threats and countermeasures.

Further information [in german], the 'Münsteraner Appell', an appeal to all stakeholders, as well as the presentations can be found at the NABU website.

Yellow-breasted Bunting: uplisted to Critically Endangered, consumption and trade go on, but there is hope

Yellow-breasted Bunting, once a superabundant songbird species, has declined by 85-95% since the early 1980s, with heavy, illegal persecution in China being an important driver. The species' status has recently been updated to Critically Endangered on IUCN's international Red List, based on a quantitative assessment of the decline led by Johannes Kamp of the Biodiversity and Ecosystem Research Group.

However, birds are still caught and sold in larger numbers, even on eBay-like platforms in China. A price of 15-30 USD per bird suggests high demand. Good news is that conservation organizations along the flyway are raising awareness, see e.g. this excellent video from Hongkong. Also, the Chinese law has been changed, and hunting and consumption are now criminal offences.
More research is underway to shed light on the year-round distribution and flyways of the species. Data on migration routes have been retrieved from geolocator devices by Wieland Heim. This will help us to identify key areas for conservation of the species, and learn more about potential additional drivers of the decline, such as land-use change and agricultural intensification on the wintering grounds.
