Internationaler Tag für biologische Vielfalt. Gärten spielen seit Jahrhunderten als Pflegestätten der Artenvielfalt eine Schlüsselrolle

Der heutige Internationale Tag für die biologische Vielfalt (IDB) der Vereinten Nationen steht dieses Jahr unter dem Motto Ernährung und Gesundheit.

Spätestens mit den alarmierenden Nachrichten über das Insektensterben ist die Bedeutung der Biodiversität ins Zentrum eines breiten öffentlichen Interesses gerückt. Gärten spielen hier seit Jahrhunderten eine Schlüsselrolle als Pflegestätten der Sorten- und Artenvielfalt von Nahrungs- und Heilpflanzen – wie der Botanische Garten der Universität Graz zeigt.

Als Biodiversitätsoase im urbanen Lebensraum beherbergt er nicht nur mehr als 5000 Pflanzenarten, sondern auch über 160 Arten an Wildbienen, die sich aus dem reichen Angebot des Gartens ihre Lieblingspflanzen aussuchen können. Die Erforschung und Archivierung der Biodiversität hat am zugehörigen Institut für Biologie der Uni Graz eine lange Tradition. Die international renommierte botanische Sammlung des Instituts umfasst etwa 1.2 Millionen archivierte Objekte, die eine Grundlage für die Erforschung der Biodiversität und ihres Wandels bilden. Derzeit sind Mitarbeiter des Instituts für Biologie intensiv mit dem Projekt Austrian Barcoding of Life (ABOL) beschäftigt, eine Initiative zur molekularbiologischen Erfassung der österreichischen Biodiversität.

Am Sonntag den 16. Juni 2019 veranstaltet die 7. fakultät gemeinsam mit dem Botanischen Garten einen "Botanik Brunch", mit Führungen, KinderWorkshops und Verkostungsstationen. Der Eintritt ist frei. Jeder ist herzlich willkommen.

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.
