Guter Bienen-Winter

Die Honigbienen in Österreich haben den heurigen Winter gut überstanden. Das ergibt eine Erhebung von ForscherInnen der Universität Graz. Foto: Pixabay

Die Sterblichkeit der Honigbienenvölker lag heuer bei zwölf Prozent

Der Anteil der Honigbienenvölker, die den Winter nicht überleben, schwankt stark über die Jahre und Regionen. Den Winter 2017/18 haben rund zwölf Prozent der geschätzten 353.000 Bienenvölker in Österreich nicht überlebt. „Die Überwinterung 2017/18 ist für die Bienen recht erfreulich verlaufen, es zeigen sich kaum Gebiete mit hohen Verlusten, die relativ geringe Zahl der verlorenen Völker wurden zum größten Teil bereits wieder nachgeschafft“, erklärt Robert Brodschneider vom Institut für Biologie der Universität Graz. Er erhebt im Rahmen des Projektes Zukunft Biene (Projektleiter Karl Crailsheim) gemeinsam mit ImkerInnen die Sterberate von Bienenvölkern in Österreich und sammelt damit wichtige Daten zum Schutz dieser Insekten. 1391 Imkereien haben dabei Angaben zu insgesamt 28.373 im Herbst 2017 eingewinterten Völkern zur Verfügung gestellt. Im Jahr davor lag die Sterblichkeit bei hohen 23 Prozent. Die Untersuchung wird auch 2019 durchgeführt, um langjährige Trends erkennen zu können.

Jurassic Sounds: Biologist reconstructs insect songs from 165 million years ago

It was apparently not just the roars of the dinosaurs that made up the soundscape of the animal world during the Jurassic period. Crickets and grasshoppers communicated through a variety of songs and high-pitched sounds, as Thorin Jonsson from the Institute of Biology at the University of Graz discovered together with colleagues from the universities of Lincoln, Bristol (UK), Beijing (China) and Tempe (USA). The findings on what are so far the oldest traces of sound on Earth have just been published in the journal PNAS.

EU funding boosts international exchange between universities

The University of Graz is further expanding its international study opportunities through the European university alliance Arqus and is taking the lead in two key projects. In future, students will benefit from even more joint degree programmes and from simplified recognition of academic achievements through the Joint European Degree Label.

Rescue and risks: Researchers have surveyed public perceptions of AI

The use of artificial intelligence has had to be made transparent since 2 August 2026. The EU’s AI Act, which has been in force since then, also sets out how risky an application is and which security measures apply as a result. However, the assessment of risks by the legislation differs in some cases significantly from the perceptions of the Austrian public. This is the finding of a representative study carried out by data scientist Stefan Thalmann from the University of Graz and his team.

The Healing Sea: Researchers discover new approaches to treating chronic inflammation in sponges

Chronic inflammation plays a key role in many diseases, ranging from metabolic disorders and cardiovascular diseases to tissue damage following injuries or infections. “Normally, the body is able to resolve inflammation on its own. If this process becomes unbalanced, immune cells remain permanently active and continue to drive negative changes in the tissue,” explains Andreas Koeberle, a pharmacist at the University of Graz.
