Aquatic ecology


Amphipods are common and abundant crustaceans found worldwide. They constitute a crucial component of macroinvertebrate communities in aquatic ecosystems and contribute substantially to the functioning of the trophic relationships within aquatic systems. Although the ecological importance and widespread distribution is recognized, the actual diversity and distribution of amphipods is still understudied in many areas, particularly in Switzerland. For example, up to now there exists no detailed overview of all amphipod species from Switzerland, no identification keys and especially very little information on amphipods in alpine and higher elevation habitats. Additionally the biogeographical role of the Swiss Alps as origin of four major drainage areas in Central Europe is generally poorly understood and needs further investigations. A high degree of endemism can be observed in plants and animals, highlighting the importance and vulnerability of these habitats. The same can be expected in amphipods, but has hitherto not been validated. With my PhD project I aim to close these gaps.
