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 ...
of Siberia (1964; originally published in Russian, 1956); Ronald Wixman, The Peoples of the USSR: An Ethnographic Handbook (1984), offers a comprehensive directory of all minority peoples of the U.S.S.R., with data for each on ethnic origin, language, population, religion, and location....

Estimated maximum temperature thresholds of tundra plants. Thresholds were estimated as the lowest AIC values when comparing generalized additive mixed models of GDDmax (calculated from 0 to 20 °C) with flower counts of the plants growing in ambient conditions observed at each location. The height...
The Arctic fox, also known as the white fox, snow fox, or polar fox, is a small-sized species with the scientific name Vulpes lagopus. It is seen in the Northern Hemisphere arctic regions and is a common animal in the Arctic Tundra biome. The arctic fox is adapted to live in cold cl...
(continuous, discontinuous and sporadic) zones. To represent the network in the Arctic properly, we identified 60 grid cells containing the location of INTERACT stations above 59° N, excluding the Greenland Ice Sheet and INTERACT sites located in Svalbard sharing the same coordinates. Seventeen ...

Diel pattern of tundra methane uptake Besides seasonal variation, CH4uptake showed distinct diel dynamics and a seasonal shift in the timing of CH4uptake peaks (Fig.2a). During June, the largest CH4uptake occurred in the afternoon (15:00–16:00), broadly corresponding to daily maxima in air ...
