Roman Alther gibt ein Liveinterview zum ökologischen Zustand der Schweizer Bäche im Radio als SRF Morgengast. Viele weitere Beiträge sind zur Originalstudie in Aqua&Gas erschienen, unter anderem in der NZZ, […]

Den Bachflohkrebs kann man fast in jedem gesunden Bach beobachten, auch im Berner Oberland. Ein Beitrag zum Tier des Jahres 2021 und zu seinen Verwandten ist im Berner Oberländer erschienen.

Der Bachflohkrebs ist ein Symbol für sauberes Wasser. In einem Beitrag zum Tier des Jahres 2021 auf TeleBielingue wird auf diesen Umstand hingewiesen. Roman Alther gibt bei Minute 6:44 einen […]

Im Untergrund und in Höhlen gibt es noch viel zu entdecken. Interview mit Roman Alther zu den Höhlenflohkrebsen im Podcast «Kopf voran» von Radio SRF vom 21.2.2020.

Environmental DNA (eDNA) is a novel tool to assess diversity in riverine ecosystems. This report shows how eDNA can be used to get information about which organisms live in and […]

Riverine ecosystems in Switzerland are dramatically changing. In a thematic broadcast, “Einstein” of the Swiss TV SRF documents how biodiversity in the river Rhine is affected by anthropogenic activities. Florian […]

Interview in Science broadcast “Forschung Aktuell” at Deutschlandfunk on our study on eDNA-based biodiversity assessment in rivers published in Nature Communications (in German).

Interview and report in the evening news of RSI on our study on eDNA-based biodiversity assessment in rivers published in Nature Communications (in Italian).

Deiner et al. (2016) show in a study published in Nature Communications that diversity in rivers can be assess using eDNA. Radio interview (RTS) of co-author Emanuel Fronhofer (in French).

Light-pollution is a global phenomenon with well-documented negative effects on the environment. In an experiment, we found a significantly reduced flight-to-light behavior of moths from light-polluted areas versus dark sky […]

Biodiversity is typically peaking at mid-altitudes. Scientists have long struggled to explain why this is the case. In a study in PNAS, we show in collaboration with scientists from EPFL […]

Moths are fatally attracted to lights. Given the high level of light pollution, it has been speculated that this could trigger evolutionary responses. In a recent experiment, we for the […]

Light-pollution is a global phenomenon with well-documented negative effects on the environment. In an experiment, we found a significantly reduced flight-to-light behavior of moths from light-polluted areas versus dark sky […]

Biodiversity in Switzerland is declining dramatically. Based on a publication by the Forum Biodiversität, the broadcast “Einstein” of the Swiss TV SRF made a documentary on these declines. Florian Altermatt […]

Aquatic Ecosystems are affected by a multitude of anthropogenic factors, ranging from climate change, to invasive species and habitat modifications. In an Interview in Aqua Viva, published by one of […]

Today, invasive animals and plants spread all around the globe. Predicting the dynamics of these invasions is of great ecological and socio-economical interest. By using laboratory microcosm experiments and computer […]

Monitoring aquatic biodiversity is challenging for many reasons. We develop novel tools using environmental DNA (eDNA) which may revolutionize the way biodiversity is measured in aquatic systems. This is for […]

Biodiversity is a key factor in preventing parasite epidemics. Altermatt & Ebert (2008) show in a study published in Ecology Letters that a high diversity of the host population is […]
