Amphipod communities in tributaries to Lake Constance

LakeConstance

Work that initially started as a small semester project in 2011, thought to provide a better understanding of amphipod communities in streams around Lake Constance, now got published in BMC Ecology. I’m really happy that Florian Altermatt suggested this project when I started my Master’s studies and that his research group continued to work on the study system. The project introduced me to the world of amphipods and this is how I eventually became an amphipodologist.

In the paper, we report replicated patterns of community composition and spatial distributions in smaller tributary streams of Lake Constance. However, invading species had no clear effect on the genetic diversity of native amphipods on this small spatial scale. This suggests that large scale observations of invasion biology may not be directly reflected on a smaller scale.

An insight into foodwebs of alpine streams

Finally, the latest paper I was involved during my Masters got released: “A note on the trophic structure of alpine streams in the Wind River Mountains, Wyoming, USA” in Fundamental & Applied Limnology. The results suggest a glacial carbon signature in stream foodwebs close to the glacier. Further a longitudinal shift in carbon sources was observed in these streams, from a glacial to an instream source and finally to a allochthonous source when moving along the system. Thanks again to the whole team. Riding to the remote sites and sampling was great fun and an exciting adventure.
