Martin Søndergaard Jørgensen.

During his PhD studies Martin has conducted research on the sexual recruitment of eelgrass (Zostera marina L.). Eelgrass is a marine flowering plant distributed in coastal areas of the northern temperature hemisphere and plays a key role in the coastal ecosystems. The sexual reproduction is of paramount importance for reestablishment of eelgrass meadows and contributes to increased genetic diversity, ensuring population resilience to changes in environmental conditions. 

In a series of laboratory and field experiments Martin studied the effects of conditions such as temperature, sediment burial and sediment characteristic on dormancy, germination and subsequent seedling establishment of eelgrass seeds. The obtained results contribute to our understanding of how such environmental factors may act as bottlenecks to the reestablishment of eelgrass, and should be taken into consideration for reestablishment projects.

The PhD degree was completed at the department of Bioscience, Science and Technology, Aarhus University.
