Fatal connection

08.05.2014

Deforestation of one of the last European primeval forests has far-reaching consequences for the plants and animals living there – this is shown in a large-scale study published by biologists from Marburg and their Polish partners in the journal “Nature Communications”. The authors take into account interactions of plants with pollinators on the one hand, and with seed dispersers on the other hand. The effects of deforestation on interaction partners are coupled to each other: If one knows the consequences for the pollinator, the consequences for seed dispersers can also be predicted.

“Many plants rely on pollination of their flowers by insects and also need birds or mammals that disperse the plant seeds", first author Jörg Albrecht explains. "In this case, pollinators and seed dispersers indirectly benefit each other because they increase the reproductive success and dispersal capacity of the shared food plants."

So far, most studies focus exclusively on a single type of interaction: e.g., on the relationship between predator and prey, or on the interaction of plants with their pollinators. But, as the authors point out, “the same species are often involved in multiple processes."

Scientists led by Associate Professor Dr. Nina Farwig and Professor Dr. Roland Brandl of the University of Marburg wanted to know whether the destruction of habitats acts in the same way on multiple interaction networks.

The researchers found strong evidence for coupled responses of pollinators and seed dispersers to logging: "Our findings signal an alarm," the authors write, "as they predict that the conversion of primary old-growth forest ecosystems to secondary habitats may involve a parallel loss of multiple animal-mediated ecosystem services."

Dr. Nina Farwig holds the Robert Bosch Junior Professorship for "Sustainable Use of Natural Resources" at the University of Marburg. The current study was part of the doctoral thesis of Jörg Albrecht in the "Conservation Ecology" group under the supervision of Nina Farwig.

The project was funded as part of a doctoral fellowship from the German Federal Environmental Foundation to Jörg Albrecht and by funds from the Robert Bosch Foundation to Nina Farwig. Co-author Professor Dr. Roland Brandl is head of the "Department of Ecology – Animal ecology" group at the University of Marburg.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
