Human taxonomy is the classification of the human species (systematic name Homo sapiens, Latin: "wise man") within zoological taxonomy. The systematic genus , Homo , is designed to include both anatomically modern humans and extinct varieties of archaic humans .
The short (3–4 month) growing season in boreal forests is sustained by greater levels of rainfall than the tundra receives (between 30 and 85 cm or 12 and 33 in per year). This biome is dominated by closed canopy forests of evergreen conifers, especially spruces, fir, pine and tamarack with some diffuse-porous hardwoods.
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.
A biome (/ ˈ b aɪ. oʊ m /) is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate. [1] [2] Biomes may span more than one continent. A biome encompasses multiple ecosystems within its boundaries
The tundra is an extremely harsh, cold, windy, and unique ecosystem found on the extreme north and south latitudes of our Earth. The soil consists mostly of frozen permafrost, which makes it difficult for extended root systems to grow, and water to drain and support a wide variety of plant life.
The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From beaver ...
Biomes include tropical rainforest, temperate broadleaf and mixed forest, temperate deciduous forest, taiga, tundra, hot desert, and polar desert. [43] Other researchers have recently categorized other biomes, such as the human and oceanic microbiomes. To a microbe, the human body is a habitat and a landscape. [44]
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra .
