Turuchan Pika
The Turuchan pika (''Ochotona turuchanensis'') is a species of pika found in isolated regions in the Central Siberian Plateau. It is a small (16–19 cm) rock dwelling species that is active during the day due to the low temperature at night. It was previously thought to be a subspecies of the Northern pika. Little is known about this species, but is known to be locally abundant. Distribution The Turuchan pika occurs from the southern reach of the Yenisei River to Lake Baikal to the middle region of the Lena River. On the Primorsky Mountain Ridge in the Irkutsk Region, 14 localities were surveyed for pika occurrence in June 2018 and July 2019. All areas were considered to be within the Northern pika's range of distribution. However, it was discovered through in-situ pika vocalizations that only the Turuchan pika was present there. Haying Behavior On the Primorsky Ridge, in the talus surrounded by taiga, researchers investigated the diversity and abundance of plant species ...

Pika
A pika ( or ; archaically spelled pica) is a small, mountain-dwelling mammal found in Asia and North America. With short limbs, very round body, an even coat of fur, and no external tail, they resemble their close relative, the rabbit, but with short, rounded ears. The large-eared pika of the Himalayas and nearby mountains is found at heights of more than , among the highest of any mammal. Pikas prefer rocky slopes and graze on a range of plants, mostly grasses, flowers and young stems. In the autumn they pull hay, soft twigs and other stores of food into their burrows to eat during the long, cold winter. The pika is also known as the whistling hare because of its high-pitched alarm call when diving into its burrow. The name ‘pika’ appears to be derived from the Tungus ''piika'', and the scientific name ''Ochotona'' is from the Mongolian word ''ogutun-a, оготно'', which means pika. It is used for any member of the Ochotonidae, a family within the order of lagomorp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Siberian Plateau
The Central Siberian Plateau (russian: Среднесибирское плоскогорье, Srednesibirskoye ploskogorye; sah, Орто Сибиир хаптал хайалаах сирэ) is a vast mountainous area in Siberia, one of the Great Russian Regions. Geography The plateau occupies a great part of central Siberia between the Yenisei and Lena rivers. It is located in the Siberian Platform and extends over an area of , between the Yenisei in the west and the Central Yakutian Lowland in the east. To the south it is bound by the Altai Mountains, Salair Ridge, Kuznetsk Alatau, the Eastern and Western Sayan Mountains and other mountains of Tuva, as well as the North Baikal Highlands and Baikal Mountains. To the north of the plateau lie the North Siberian Lowland and to the east the plateau gives way to the Central Yakutian Lowland and the Lena Plateau.

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Pika
The northern pika (''Ochotona hyperborea'') is a species of pika found across mountainous regions of northern Asia, from the Ural Mountains to northern Japan and south through Mongolia, Manchuria and northern Korea. An adult northern pika has a body length of , and a tail of . The pika sheds its fur twice annually, bearing a reddish-brown coat in the summer and grayish-brown coat in winter.

In Situ
''In situ'' (; often not italicized in English) is a Latin phrase that translates literally to "on site" or "in position." It can mean "locally", "on site", "on the premises", or "in place" to describe where an event takes place and is used in many different contexts. For example, in fields such as physics, geology, chemistry, or biology, ''in situ'' may describe the way a measurement is taken, that is, in the same place the phenomenon is occurring without isolating it from other systems or altering the original conditions of the test. The opposite of ''in situ'' is ''ex situ''. Aerospace In the aerospace industry, equipment on-board aircraft must be tested ''in situ'', or in place, to confirm everything functions properly as a system. Individually, each piece may work but interference from nearby equipment may create unanticipated problems. Special test equipment is available for this ''in situ'' testing. It can also refer to repairs made to the aircraft structure or flight con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taiga
Taiga (; rus, тайга́, p=tɐjˈɡa; relates to Mongolic and Turkic languages), generally referred to in North America as a boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest has been called the world's largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous United States. In Eurasia, it covers most of Sweden, Finland, much of Russia from Karelia in the west to the Pacific Ocean (including much of Siberia), much of Norway and Estonia, some of the Scottish Highlands, some lowland/coastal areas of Iceland, and areas of northern Kazakhstan, northern Mongolia, and northern Japan (on the island of Hokkaidō). The main tree species, depending on the length of the growing season and summer temperatures, vary across the world.

Veratrum Nigrum
''Veratrum nigrum'', the black false hellebore,Bonine, ''Black Plants: 75 Striking Choices for the Garden,'' 2009, p. 75.Toogood, ''The Gardener's Encyclopedia of Perennials,'' 1988, p. 144. is a widespread Eurasian species of perennial flowering plant in the family Melanthiaceae.Barceloux, ''Medical Toxicology of Natural Substances,'' 2008, p. 815. Despite its common name, ''V. nigrum'' is not closely related to the true hellebores, nor does it resemble them. The plant was widely known even in ancient times. For example, Lucretius (ca. 99 BCE – ca. 55 BCE) and Pliny the Elder (23 AD – August 25, 79) both knew of its medicinal emetic as well as deadly toxic properties. Distribution and habitat ''Veratrum nigrum'' is native to Eurasia from France to Korea including Germany, Poland, Russia, China, and Mongolia.Armitage, ''Armitage's Garden Perennials: A Color Encyclopedia,'' 2000, p. 269.

Urtica Dioica
''Urtica dioica'', often known as common nettle, burn nettle, stinging nettle (although not all plants of this species sting) or nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, it is now found worldwide, including New Zealand and North America. The species is divided into six subspecies, five of which have many hollow stinging hairs called trichomes on the leaves and stems, which act like hypodermic needles, injecting histamine and other chemicals that produce a stinging sensation upon contact ("contact urticaria", a form of contact dermatitis). The plant has a long history of use as a source for traditional medicine, food, tea, and textile raw material in ancient (such as Saxon) and modern societies. Description ''Urtica dioica'' is a dioecious, herbaceous, perennial plant, tall in the summer and dying down to the ground in winter. ...
