Biodiversity and response to climate change


Several deep ice cores from Greenland have already been investigated for ancient DNA. DYE-3 in south Greenland and Camp Century in North West Greenland have provided results on past biodiversity. The GRIP cores was a site that did not provide ancient plant DNA results. More cores will be studied in the future and we might therefore be able to get a broader understanding on how the ecosystems have reacted to climate changes and how the icecap have fluctuated in size through time.

Applying genetic methods to the material in the basal ice can describe past biodiversity. The composition of the biodiversity preserved in different ice cores prove information about the local temperature and precipitation conditions that were characteristic of the climate at the time when the area was last ice free.

The composition of species and their response to climate change can be modelled by comparing the biodiversity from different ice cores and sites. With these models,the researchers have a good tool for predicting how present day ecosystems will respond to climate variability and change.
