Arctic Ecosystems

Arctic ecosystems refer to the interconnected terrestrial, freshwater and marine environments found in the Arctic region, characterized by low temperatures, seasonal light extremes and permafrost in many areas. They include tundra landscapes, sea ice habitats, polar deserts, boreal transition zones and Arctic Ocean systems. Arctic ecosystems support specialized plant and animal species adapted to cold conditions and are highly sensitive to climate warming, sea ice decline and shifts in hydrology and biodiversity.
