Blüten wie Heu

BiologInnen der Uni Graz bringen Artenvielfalt auf Wiesen zurück

Der Duft von frischem Heu ist ein seltener Genuss geworden. Die Mahd wird nämlich rasch in Siloballen gepackt – und zwar schon vor dem Aufblühen der Gräser. „Dann ist das Futter für die Viehhaltung am proteinreichsten“, erklärt Martin Magnes, Biologe an der Universität Graz. Allerdings geht so auch die Artenvielfalt verloren: Die zu früh geschnittenen Pflanzen können sich nicht aussäen, ohne Blüten finden Insekten zu wenig Nahrung, damit wiederum fällt eine wichtige Futterquelle für Vögel weg. „Außerdem finden Vögel und Wildbienen auf den getrimmten Agrarflächen weniger Brutmöglichkeiten“, ergänzt der Wissenschafter.

Um auch in Mitteleuropa wieder artenreiche Wiesen und vielfältige Lebensräume zu schaffen, untersucht Magnes mit einem internationalen Team traditionell bewirtschaftetes Grünland in den Karpaten. „Dort wird mit hofeigenem Festmist gedüngt, die erste Mahd erfolgt spät, dafür werden die Wiesen im Frühjahr kurz beweidet“, zählt er Praktiken auf, die auch bei uns zum Einsatz kommen könnten. „Die artenreichen Flächen mit Gräsern und Kräutern liefern nicht nur Insekten Nahrung, sondern auch dem Vieh ein nährstoffreicheres und gesundes Futter“, ergänzt er. Über ein Crowdfunding-Projekt soll nun eine weitere Forschungsexpedition in wenig untersuchte Regionen finanziert werden. „Wir erwarten uns konkrete Hinweise, wie das verarmte Grünland in Mitteleuropa wieder optimal bewirtschaftet werden könnte“, so der Biologe.

Fair distribution: Researchers determine just greenhouse gas budgets for all EU regions

Ten years ago, on 12 December 2015, the Paris Climate Agreement was signed at the UN Climate Conference. In order to limit global warming to well below two degrees, only a certain amount of CO2 may be emitted worldwide. While the focus was originally on national emission targets, more than 200 subnational regions and almost 300 cities have now adopted their own targets. But how many emissions are they fairly entitled to? Researchers at the University of Graz have now developed transparent criteria for fair distribution at the subnational level for the first time and determined corresponding greenhouse gas budgets for all European regions. The paper was published today in the scientific journal Nature Communications.

Chemical Christmas show at the University of Graz: An explosive evening at the Schauspielh

At the beginning of December, the University of Graz transformed the theater into a laboratory: as part of “Chemical Life,” teacher training students staged a chemical Christmas show for Styrian school classes—complete with ethanol rockets, nitrogen snow, and glowing effects. An evening designed to inspire interest in studying chemistry.

Train by train: Koralm railway accelerates exchange between the Universities

Lectures at the University of Klagenfurt in the morning, seminars at the University of Graz in the afternoon: Austria's longest tunnel and a journey time of around 45 minutes make it easy. The Koralm railway increases the speed of networking between the two university locations. The collaboration builds on existing cooperation - for example in the areas of teacher training, Slavic studies and as employers, the universities are well coordinated.
