The bright colors of Grand Prismatic Spring and Yellowstone National Park, are produced by thermophiles, a type of extremophile.. An extremophile (from Latin extremus 'extreme' and Ancient Greek φιλία (philía) 'love') is an organism that is able to live (or in some cases thrive) in extreme environments, i.e., environments with conditions approaching or stretching the limits of what known ...
Among domesticated animals, yaks (Bos grunniens) are the highest dwelling animals of the world, living at 3,000–5,000 m (9,800–16,400 ft). The yak is the most important domesticated animal for Tibet highlanders in Qinghai Province of China, as the primary source of milk, meat and fertilizer.
One example of primary succession takes place after a volcano has erupted. The lava flows into the ocean and hardens into new land. The resulting barren land is first colonized by pioneer organisms, like algae, which pave the way for later, less hardy plants, such as hardwood trees, by facilitating pedogenesis, especially through the biotic acceleration of weathering and the addition of ...
Endolith lifeform found inside an Antarctic rock. An endolith or endolithic is an organism (archaeon, bacterium, fungus, lichen, algae, sponge, or amoeba) that is able to acquire the necessary resources for growth in the inner part of a rock, [1] mineral, coral, animal shells, or in the pores between mineral grains of a rock.
The generic name Chrysomallon is from the Ancient Greek language, and means "golden haired", because pyrite (a compound occurring in its shell) is golden in color. [2] The specific name squamiferum is from the Latin language and means "scale-bearing", because of its sclerites. [2] At first it was not known to which family this species belonged. [8]
The volcano rabbit’s adult weight ranges from 386 to 602 g (0.851 to 1.327 lb). [7] It has short, dense fur that ranges in color from brown to black. [8] The rabbit is a gnawing animal that is distinguished from rodents by its two pairs of specialized upper incisors. [9]
[33] [34] The name water bear comes from the way they walk, reminiscent of a bear's gait. The name Tardigradum means 'slow walker' and was given by Lazzaro Spallanzani in 1776. [ 35 ] [ 10 ] In 1834, C.A.S. Schulze gave the first formal description of a tardigrade, Macrobiotus hufelandi , in a work subtitled "a new animal from the crustacean ...
[14] [15] [16] A dose of 5,000 Gy is estimated to introduce several hundred double-strand breaks (DSBs) into the organism's DNA (~0.005 DSB/Gy/Mbp (haploid genome)). For comparison, a chest X-ray or Apollo mission involves about 1 mGy, 5 Gy can kill a human, 200–800 Gy will kill E. coli , and more than 4,000 Gy will kill the radiation ...
