Arctic tundra is a very cold, windy, and treeless biome that’s snow-covered for much of the year. It’s found in the northern hemisphere, encircling the north pole and extending south across parts of Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, to the coniferous forests o...

The largest tundra region completely devoid of forest is an area of 3 million km 2 in northern Siberia. At most, there are 188 days in the year with a mean temperature above 0掳C, and sometimes as few as 55. The low summer temperatures are partially due to the large amount of heat ...
The Arctic is highly sensitive to climate change, and the rise in its near-surface air temperatures has been almost twice the global average. The increased growth of the Arctic tundra and its changing seasonality have been observed, largely in response to the impacts of climate change. In this...
Because of the geopolitical consequences of the Russian attack on Ukraine, the ability to both track and further project the development of the Arctic biome following climate-induced ecosystem change has deteriorated. And with that, the ability to initiate well-informed management and conservation initi...
Arctic warming can influence tundra ecosystem function with consequences for climate feedbacks, wildlife and human communities. Yet ecological change across the Arctic tundra biome remains poorly quantified due to field measurement limitations and reliance on coarse-resolution satellite data. Here, we ...

In the Arctic, however, plants are not as abundant due to the harsh climate conditions. This means that a food chain in the Arctic may appear very different from one observed in a forest or prairie. Like in all food chains, the levels of a typical food chain found within the Arctic ...

Biome survival: Part I 24 The plants of the tundra start flowering surprisingly early, as soon as the snow starts to melt, such as willow (Salix herbacea, lower photo), although some flower while there is still snow on the ground, such as the Arctic willow (S. 2 Life in the tundra ...
