PhD project:

Winter ecophysiology of Arctic kelps

 

I completed my studies in Biology (Diplom; Major: Zoophysiology and Behaviour) in Oldenburg, and graduated in Marine Biology (Master of Science; Major: Marine Botany) in Bremen.

 

Since 2016 (interrupted by parental leave) I’ve been working on my PhD project, which is primarily concerned with the responses of High Arctic kelp to the challenges of global warming due to the Climate Crisis.

 

The first part of my project investigated kelp eco-physiology during the Polar Night. Here we found the kelps’ long-term storage glucan, laminarin, to be crucial for the plants’ survival during polar night. Marked differences regarding storage amount and consumption were observed between the investigated boreal-temperate species (Saccharina latissima) and Arctic-endemic species (Laminaria solidungula), and further increases in ambient temperature due to the Climate Crisis were found to likely affect both species, but in different ways (Scheschonk et al. 2019).

The second part of my thesis investigates epigenetic variances in lab-grown and field sampled specimen of Saccharina latissima, for which a collaboration with Uni Nord in Bodø, Norway,could be established.
