Extreme winter minimums in the northern taiga are typically lower than those of the tundra. There are taiga areas of eastern Siberia and interior Alaska-Yukon where the mean annual temperature reaches down to −10 °C (14 °F), [11] [12] and the lowest reliably recorded temperatures in the Northern Hemisphere were recorded in the taiga of ...
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]
Terrestrial ecosystems occupy 55,660,000 mi 2 (144,150,000 km 2), or 28.26% of Earth's surface. [5] Major plant taxa in terrestrial ecosystems are members of the division Magnoliophyta (flowering plants), of which there are about 275,000 species, and the division Pinophyta (conifers), of which there are about 500 species.
The Urals montane tundra and taiga ecoregion (WWF ID: PA0610) covers the main ridge of the Ural Mountains (both sides) - a 2,000 km (north-south) by 300 km (west-east) region. The region is on the divide between European and Asian ecoregions, and also the meeting point of tundra and taiga.
Alpine tundra in the North Cascades of Washington, United States. Alpine tundra does not contain trees because the climate and soils at high altitude block tree growth. [26]: 51 The cold climate of the alpine tundra is caused by the low air temperatures, and is similar to polar climate. Alpine tundra is generally better drained than arctic ...
The Scandinavian and Russian taiga is an ecoregion within the taiga and boreal forests biome as defined by the WWF classification (ecoregion PA0608). [1] It is situated in Northern Europe between tundra in the north and temperate mixed forests in the south and occupies about 2,156,900 km 2 (832,800 sq mi) in Norway, Sweden, Finland and the northern part of European Russia, being the largest ...
The boreal and temperate Euro-Siberian region is the Palearctic's largest biogeographic region, which transitions from tundra in the northern reaches of Russia and Scandinavia to the vast taiga, the boreal coniferous forests which run across the continent.
Tundra exploration vehicles used for oil development and polar bear tours ("an eco-friendly" industry) leave traces of tire marks for 20-plus years after a disturbance occurs. Other factors such as high CO 2 emissions from tourism and from warming tundra soil, create a positive feedback loop, accelerating changes to the tundra.
