A new study by Bayreuth scientists Dr. Franz-Sebastian Krah and Prof. Dr. Claus Bässler has shown that temperature has a significant influence on the timing and duration of fungal fruiting in key areas of the world. The research results were published in the journal "Ecology Letters" and shed new light on the global impact of climate change on occurrences of fungi in nature.
Lithium-oxygen batteries, often hailed as the future of rechargeable energy storage, presently face limitations that prevent their widespread adoption. One of these significant constraints is the occurrence of large overpotentials experienced during the charging process. This means that the voltage needed for charging increases substantially implying low efficiency. In a new study published in the journal "Chem", Prof. Dr. Francesco Ciucci of the University of Bayreuth and research partners in China have for the first time been able to identify and explain the causes of these overpotentials.
- Recalculation includes gas leakages and incomplete combustion. - Electricity can be the climate-friendlier choice for cooking and heating. - Study of 25 countries shows: the share of renewable energies in the overall power generation mix makes the difference. Heating and cooking with natural gas often has a greater impact on the climate than commonly believed. This is a conclusion of a new, more realistic calculation model developed by researchers at the Technical University of Munich (TUM). The difference: the researchers’ model also takes into account the enormous quantities of unused gas released into the atmosphere.
On Germany’s highest mountain, the Zugspitze, the air is thin and contains very few pollutants. Ultrafine particles only exist there when they are transported through the atmosphere over long distances. A research team from the University of Bayreuth led by Prof. Dr. Anke Nölscher has now installed a new module for collecting ultrafine particles at the summit of the Zugspitze. The sampling at the Schneefernerhaus Environmental Research Station and the subsequent laboratory analyses are part of the Bavarian project network "BayUFP - Measurement, Characterization and Evaluation of Ultrafine Particles", which is funded by the Bavarian State Ministry of the Environment and Consumer Protection.
For several years, ecological research has argued that climate often has no determining influence on the distribution of forests and savannas in tropical regions. However, an international research team led by Prof. Dr. Steven Higgins at the University of Bayreuth has now succeeded in proving that it depends mostly on climatic factors whether regions in Africa are covered by forest or savanna. The study, published in "Science", thus confirms the dominant role of climate in the formation of global vegetation patterns.
Increasing heat and drought are changing forests faster than expected. Researchers at the University of Würzburg want to keep a better eye on these dynamics. The Bavarian Research Institute for Digital Transformation (bidt) of the Bavarian Academy of Sciences and Humanities is funding their project with 1.2 million euros.
214 wild bee species, and thus a little more than 40 per cent of the bee species found in Bavaria, were detected last year in the Ecological-Botanical Garden of the University of Bayreuth (ÖBG) as part of a master's thesis. Among them were four species threatened with extinction, such as Ammobates punctatus, as well as numerous other endangered species.
Artificial intelligence should soon make it possible to detect forest fire hazards earlier than before and to fight forest fires more effectively. This is the goal of the joint project "AI-based Forest Monitoring - Artificial Intelligence for Early Detection of Forest Fire Events (KIWA)", in which the University of Bayreuth is participating with its research competencies in biogeography and disturbance ecology. The German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) is funding the project for the next two years with a total of around 1.8 million euros
How to reduce emissions in the transport sector while maintaining our mobility? "SynphOnie", a research cluster funded by the German Federal Ministry of Education and Research (BMBF) that includes a team of researchers from the University of Passau headed by Professor Tobias Harks, is developing a mathematical model of transport flows to help make transport planning both needs-based and sustainable.
Growing electromobility poses new challenges for the infrastructure: Stations for charging batteries must be optimally integrated into the stationary energy network available on site. A comprehensive charging concept for different vehicle types is necessary. The goal of the joint project "eMobiGrid", in which the University of Bayreuth, three medium-sized companies and the Fraunhofer-Gesellschaft are working closely together, is to develop practical solutions for these challenges and thus accelerate the traffic turnaround. The German Federal Ministry of Digital and Transport (BMDV) is funding the project with a total of around three million euros for three years.
