Global change effects in high arctic ecosystems: experimental physical-ecological and paleo-ecological approach of tendencies in biodiversity and community structures


The main question around which this program pivots is: how will communities of organisms deal with the expected warming in the Arctic? Several approaches are used: what is the present ecological situation (recent ecology ), what can we learn of the past communities (palaeo-ecology), and what is their response to a warmer microclimate (radiation-experiment). The studied organisms are higher plants, diatoms and testate amoebae.
