How will these resources help you?

As geographical studies focus on extreme environments and cold regions, this resource list will help students and teachers understand the ecosystems of both the Arctic and Antarctica. What characterises these polar ecosystems is the relatively low biodiversity of its wildlife and their reproduction rates, along with finely tuned responses to seasonal changes. The effects of climate change lead to an increasingly unstable and fragile ecosystems as food chains collapse and species decline. As polar environments are disproportionately affected by climate change, the importance of studying these regions to see how species survive the harsh conditions is crucial.
