Eawag - Swiss Federal Institute of Aquatic Science and Technology

We study ecology, evolution and biodiversity of fishes and other aquatic organisms. We are interested in the mechanisms that drive the origins, the maintenance and the loss of species, genetic and functional diversity.

Insects and spiders are superfoods: rich in essential fatty acids and therefore an important food supply for birds, fish, reptiles, amphibians and small mammals.

Aeschlimann, A., Fehle, P., Neuhaus, M., Ingold, K., Fischer, M., Zinn, N., … Seehausen, O. (2024). Den Biodiversitätsverlust der Gewässer stoppen – trotz Klimawandel. Zwischenbericht Phase I (2020 - 2023): Projekt LANAT-3, Wyss Academy for Nature Hub Bern. Bern: Wyss Academy for Nature. , Institutional Repository

Die Schweizer Gewässerbiodiversität ist stark gefährdet und der Klimawandel sowie andere direkte und indirekte Treiber des Biodiversitätsverlustes verstärken sich zunehmend. Während gesetzliche und strategische Grundlagen zum Schutz der Schweizer Gewässerbiodiversität vorhanden sind, steht deren Vollzug vor vielen Herausforderungen wie beispielsweise fehlenden Datengrundlagen, mangelnden Ressourcen, Zielkonflikten und ungenügendem Austausch zwischen relevanten Akteuren. Das Projekt LANAT-3 der Wyss Academy for Nature hat sich zum Ziel gesetzt, Lösungen für diese Herausforderungen zu erarbeiten. Dieser Bericht fasst die Erkenntnisse der ersten Projektphase (2020-2023) zusammen. [...]

La biodiversité aquatique suisse est gravement menacée et le changement climatique ainsi que d'autres facteurs directs et indirects de perte de biodiversité augmentent de plus en plus. Bien qu'il existe des fondements juridiques et stratégiques pour protéger la biodiversité aquatique suisse, leur mise en oeuvre se heurte à de nombreux défis tels que par exemple l'absence de données, manque de ressources, les conflits d'objectifs et des échanges insuffisants entre les acteurs pertinents. Le projet LANAT-3 de la Wyss Academy for Nature vise à développer des solutions à ces défis. Ce rapport résume les conclusions de la première phase du projet (2020-2023). [...]

La biodiversità acquatica svizzera è in grave pericolo, poiché i cambiamenti climatici, in concomitanza con altri fattori diretti e indiretti di perdita di biodiversità, sono in crescente aumento. Sebbene esistano basi giuridiche e strategiche per proteggere la biodiversità acquatica svizzera, la loro attuazione deve far fronte a numerose sfide, tra cui la mancanza di dati, la scarsità di risorse, gli obiettivi contrastanti e uno scambio insufficiente tra gli attori rilevanti. Il progetto LANAT-3 della Wyss Academy for Nature mira a sviluppare soluzioni a queste sfide. Il presente rapporto riassume i risultati della prima fase del progetto (2020-2023). [...]

Swiss aquatic biodiversity is under great risk, with climate change and other direct and indirect drivers of biodiversity loss increasing. While there exist legal and strategic foundations for protecting Swiss aquatic biodiversity, their implementation faces many challenges such as a lack of data and resources, as well as conflicting objectives and insufficient exchange between relevant actors. The Wyss Academy for Nature's LANAT-3 project aims to develop solutions to these challenges. This report summarizes the findings of the first project phase (2020-2023). [...]
