Insektenvielfalt in der Schweiz Bedeutung, Trends, Handlungsoptionen

SWISS ACADEMIES FACTSHEETS, VOL. 16. NO 4, 2021

Die Situation der Insekten in der Schweiz ist besorgniserregend. Die Vielfalt und Grösse der Insektenbestände ist vor allem im Mittelland stark zurückgegangen – eine Tendenz, die mittlerweile auch im Jura und in den Alpen feststellbar ist. Von den aktuell 1153 im Rahmen der Roten Listen bewerteten Insektenarten sind fast 60 % gefährdet oder potenziell gefährdet. Sollen die teils dramatischen Entwicklungen gestoppt, müssen die bestehenden Instrumente zur Erhaltung und Förderung gefährdeter Lebensräume und Arten angepasst und ergänzt werden. Dafür schlagen die Autorinnen und Autoren ein wissenschaftlich fundiertes 12-Punkte-Programm vor. Das vorliegende Faktenblatt zeigt die wichtigsten Erkenntnisse aus dem ersten umfassenden Zustandsbericht «Insektenvielfalt in der Schweiz», den das Forum Biodiversität der Akademie der Naturwissenschaften Schweiz im September 2021 publiziert hat.

    STEM 2026: Where Switzerland stands today

    Twelve years on from the first STEM Youth Barometer, the new 2026 edition reveals that interest in STEM has remained largely stable, stereotypes persist, and women underestimate their own abilities. At the same time, the findings are more nuanced than expected and point to clear areas for improvement.

    Impact of AI on Early Career Researchers: Challenges, Opportunities and Responsibilities

    Artificial Intelligence (AI) is rapidly transforming science and is therefore profoundly reshaping the work of Early Career Researchers. Against this backdrop, the publication Impact of AI on Early Career Researchers: Challenges, Opportunities, and Responsibilities, developed by members of the Swiss Young Academy, namely Emmanuel Senft, Sabrina H. Kessler, Pamela Delgado, Devi Bühler, and Alexandre Bovet, offers a timely interdisciplinary reflection on these changes. The booklet examines both the opportunities and risks of AI across five key areas – research, teaching, science communication, policymaking, and sustainability – while also addressing critical issues such as research integrity, data privacy, misinformation, governance, and environmental impact. It further highlights the responsibilities of Early Career Researchers and higher education institutions in promoting AI literacy, transparency, ethical standards, and responsible use of AI in science.
