Job description:Master of Science Project “Impact of heatwaves on microbial communities”

Microbial communities in summer are more balanced and kept in check by grazers compared to spring bloom microbial communities. Blooms, if they occur, are rather rare and short lived. How this balance is changing with progressing climate change, and especially with heatwaves which are gaining in intensity and frequency is not yet know. To tackle this key scientific challenge, we compare ambient in situ conditions with a “heat wave” scenario mimicking occasionally occurring anomalous heat events in the North Sea. Within this Master thesis the candidate will focus on the influence of grazing on the microbial community composition. Is there a selective grazing on specific bacterial groups? Does the grazing preference shift to different prey bacteria under the influence of a heatwave?

To answer these questions, samples will be analyzed by Fluorescence-In-Situ-Hybridization and automated counting at the Max-Planck-Institute (Bremen), and combined to sequencing and taxonomic data gained at the Alfred-Wegener-Institute.
