The MultiKulti team has the great pleasure of welcoming Ellen Oldenburg, M.Sc., quantitative biologist for a lecture in the monthly webinar on 11th of May 2023, 4 pm. Ellen will share some insights into her research on microbial communities in a warming Arctic ocean. Guest listeners are very welcome.
Microbial communities in Arctic seawater are major contributors in climate feedback systems and in food webs in the polar ecosystem. Given the importance of Arctic research in understanding global warming, this ecosystem is studied in a variety of ways.
The following important questions emerge:
- Which environmental and interactive factors will be major drivers for microbial community composition in the Arctic Ocean of the future?
- How do co-occurrence dynamics of zoo- and phytoplankton align with prokaryotic blooms?
- In populations dynamics, do viral infections outweigh grazer effects and environmental factors in terms of mortality?
The team of Ellen Oldenburg at the Institute of Quantitative and Theoretical Biology at the University of Düsseldorf applied these questions to different data sets. They use the result of the data analysis to model species interactions considering co-occurrences and literature information on mutualistic, parasitic, symbiotic, and predator-prey relationships. In regard of changing environmental conditions in Arctic regions, the talk will provide a perspective on how microbial communities in the Central Arctic Ocean might change in the near future.
Ellen Oldenburg is a PhD candidate researching microbial conditions in the Arctic Ocean, using data from the MOSAiC expedition of the Alfred Wegener Institute (AWI) and from the FRAM long-term observatory. Her work group at the University of Düsseldorf is cooperating with the AWI and the Max Planck Institute in this research project, with support from the German Reserach Foundation.
The webinar will take place on the 11th of May 2023 at 4 pm CET online. Interested guests are welcome to receive the login data for the Zoom online meeting by sending a mail to info@multikultivierung.de
