The sub-Arctic lakes were chosen to span a geographical gradient from the southern inland to the costal northeast, reflecting a gradi- ent in biome domination from taiga to Arctic tundra. A high proportion of the high-Arctic lakes are situated on limestone bedrock, with elevated alkalinity (Fig...
Muskoxen are physiologically and behaviourally adapted to live year-around in the cold conditions of the Arctic tundra. Once widely distributed across the Holarctic, the present endemic population is restricted to Northern Canada and Greenland. In the last century, muskoxen have been reintroduced to ...
Eriophorum vaginatum, a dominant species across these tundra types) compared to southern species growing in the same location in a common garden experiment40. The phenotypic variation was shown to be persisting for decades41, and ecotypes may be unable to extend their effective growth period or ...
What separates the tundra from a boreal forest? What portion of Alaska is in the Arctic Circle? What are the three natural resources in the Arctic region? What is the significance of the Arctic Circle? What are the geographic features of Canada?
Tundra - Climate Change, Human Impact, Arctic: Earth’s tundra regions are harsh and remote, so fewer humans have settled there than in other environments. However, humans have a long history in the tundra. For example, the first people who went to North

We found that the evidence base for the effects of herbivore diversity on tundra ecosystems is also geographically and taxonomically uneven. Most of the available knowledge comes from well-established research locations. This geographic bias in tundra data has previously been described for Arctic studie...
For Indigenous Peoples and local communities across the Arctic, rapid changes in climate have affected the ability to safely use semi-permanent trails on sea ice, lakes, rivers, ocean, and tundra (herein referred to as “trails”)1. These trails are often the only way of traveling from settl...
