PhD Topic/Title: Successional processes and biogeochemical cycling in high Arctic ecosystems.


The effects of global climate change were very noticeable in the Netherlands last year. Several heat, cold and precipitation records were broken. Effects in high Arctic ecosystems should be much higher than in a small country with a temperate maritime climate. The study focusses on successional processes that proceed in polar landscapes due to melting and retreating ice masses and rapid changes in biogeochemical cycles. The aim is to quantify the relative importance of external disturbances to these processes.
