A Niphargus hotspot in Switzerland

Three new species described

Our most recent paper in Systematics and Biodiversity reveals three new and endemic species of Niphargus in Switzerland. We describe them from the Hölloch cave system in central Switzerland, with no further findings known so far. The paper updates the current knowledge of amphipoda in Switzerland, specifically for the genus of Niphargus.

A fruitful collaboration

Thanks to the collaboration with the caving society of the Hölloch we could retrieve the exciting samples. It was also them who provided the names given to the new species. Without their knowledge about the gigantic cave system we would not have been able to publish these results.

An endemic amphipod of the Alps

In our most recent paper, Florian Altermatt, Cene Fišer, and me describe a new  amphipod species that is endemic to the Alps. What has been considered to belong to the circumboreal Gammarus lacustris species complex turned out to be a highly diverged lineage. It represents an own species within the Alps. Given its natural but restricted distribution, we name the endemic amphipod species Gammarus alpinus sp. nov.

Already endangered?

The species is commonly found in high alpine lakes of Central Europe. Although its wide distribution, invasive species and increasing anthropogenic pressure in its natural habitat impose challenges to the newly described species. Assigning a name to this biological entity hopefully facilitates the conservation efforts. Our study is published in the Zoological Journal of the Linnean Society. It highlights the importance of combining different methods to resolve cryptic diversity. Furthermore I would hereby like to acknowledge all the people and institutions that helped to conduct this study.
