Marine Biodiversity of the polar regions in times of climate change:
Climate change will have different ramifications for the biodiversity of marine polar biota. As the effects influence each other, they are generally complex, often non-linear and thus difficult to predict.
Due to the marked sensibility of the often highly adapted polar organisms and communities, it is very likely that climate-driven environmental change will result in biodiversity variations in various directions, both rise and decline, as well as pronounced faunal community shifts.
In addition, increasing human activities in high-latitude regions affect marine biodiversity, currently chiefly in the Arctic, through exploration and exploitation of natural and mineral resources, shipping and tourism.
In both the Arctic and Southern Ocean, however, international agreements are underway to better preserve marine biodiversity than through current measures, for example by establishing networks of marine protected areas.
