One of the planet's most recent biomes, a result of the last ice age only 10,000 years ago, the tundra contains unique flora and fauna formed during the last glaciation in areas unrestricted by permanent ice. The tundra region is found in high latitudes, primarily in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as the ...
In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic tundra, [2] alpine tundra, [2] and Antarctic tundra. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses ...
Alaska is the most biodiverse state with 15 ecoregions across three biomes in the same realm. California comes in a close second with 13 ecoregions across four biomes in the same realm. By contrast, Rhode Island is the least biodiverse with just one ecoregion—the Northeastern coastal forests —encompassing the entire state.
The geography of Texas is diverse and large. Occupying about 7% of the total water and land area of the U.S., [1] it is the second largest state after Alaska, and is the southernmost part of the Great Plains, which end in the south against the folded Sierra Madre Oriental of Mexico.
This page features a list of biogeographic provinces that were developed by Miklos Udvardy in 1975, [1] [2] later modified by other authors. [according to whom?] Biogeographic Province is a biotic subdivision of biogeographic realms subdivided into ecoregions, which are classified based on their biomes or habitat types and, on this page, correspond to the floristic kingdoms of botany.
The tundra has become a source of emissions, rather than a carbon sink, the authors said. The Arctic is heating up far faster than places at lower altitudes as melting ice reflects less radiation ...
