Corispermum ulopterum is a species of flowering plant in the family Amaranthaceae, native to Irkutsk Oblast in Siberia. [1] It is found only on the beaches of Lake Baikal. [2]
Lake Baikal is a rift lake located in Russia situated in southern Siberia between the federal subjects of Irkutsk Oblast to the northwest and Buryatia to the southeast.
The Angara is a major river in Siberia, which traces a course through Russia's Irkutsk Oblast and Krasnoyarsk Krai. It drains out of Lake Baikal and is the headwater tributary of the Yenisey. It is 1,849 kilometres (1,149 mi) long, and has a drainage basin of 1,039,000 square kilometres (401,000 sq mi). It was formerly known as the Lower or Nizhnyaya Angara. Below its junction with the Ilim, it was formerly known as the Upper Tunguska and, with the names reversed, as the Lower Tunguska.
The Baikal seal, Lake Baikal seal or nerpa, is a species of earless seal endemic to Lake Baikal in Siberia, Russia. Like the Caspian seal, it is related to the Arctic ringed seal. The Baikal seal is one of the smallest true seals and the only exclusively freshwater pinniped species. A subpopulation of inland harbour seals living in the Hudson Bay region of Quebec, Canada, the Saimaa ringed seal and the Ladoga seal are found in fresh water, but these are part of species that also have marine populations.
The Selenga or Selenge is a major river in Mongolia and Buryatia, Russia. Originating from its headwater tributaries, the Ider and the Delger mörön, it flows for 992–1,024 kilometres (616–636 mi) before draining into Lake Baikal. The Selenga therefore makes up the most distant headwaters of the Yenisey-Angara river system.
The omul, Coregonus migratorius, also known as Baikal omul, is a whitefish species of the salmon family endemic to Lake Baikal in Siberia, Russia. It is considered a delicacy and is the object of one of the largest commercial fisheries on Lake Baikal. In 2004, it was listed in Russia as an endangered species.
Comephorus, known as the golomyankas or Baikal oilfish, are a genus comprising two species of peculiar, sculpin fishes endemic to Lake Baikal in Russia. Comephorus is the only genus in the family Comephoridae. Golomyankas are pelagic fishes which make the main food source of the Baikal seal.
The Botanic Garden of the Irkutsk State University is a botanic garden in Irkutsk, Siberia, Russia.
Carcross Desert, located outside Carcross, Yukon, Canada, is often considered the smallest desert in the world. The Carcross Desert measures approximately 2.6 km2 (1.0 sq mi), or 259 ha.
The Circum-Baikal Railway is a historical railway in the Irkutsk region of Russia. It runs along the Northern shore of the Southern extremity of the lake from the town of Slyudyanka to the Baikal settlement. Until the middle of the 20th century the Circum-Baikal railway was part of the main line of Trans-Siberian Railway; later on, however, a duplicate section of the railway was built. Sometimes called a unique achievement in engineering, the Circum-Baikal is one of the picturesque sights of the area around Lake Baikal.
Corispermum is a genus of plants in the family Amaranthaceae. Common names given to members of the genus involve bugseed, tickseed, and tumbleweed. In general, these are erect annual plants with flat, thin leaves and topped with inflorescences of flowers with long bracts. Bugseeds are native to North America and Eurasia, but little is known about their taxonomy and distribution.
The Baikal Rift Zone is a series of continental rifts centered beneath Lake Baikal in southeastern Russia. Current strain in the rifts tends to be extending with some shear movement. A series of basins form along the zone for more than 2,000 kilometres (1,200 mi), creating a rift valley. The rifts form between the Eurasian Plate to the west and the Amur Plate to the east.
Marina Rikhvanova is a Russian ecologist and leader of the Baikal Ecological Wave (BEW) organization which protects Siberia's Lake Baikal from ecological damage. Lake Baikal, the world's biggest reservoir of fresh water, is currently under threat from industrial pollution. In 2008, Rikhvanova was awarded the Goldman Environmental Prize.
The Baikal Nature Reserve is a nature reserve on the southeast shore of Lake Baikal, in southern Buryatia, Russia. Also called Baikal Zapovednik, it was established in 1969 for preserving the nature along the lake and the neighboring central part of the Khamar-Daban Range. The area of this nature reserve is 165,700 hectares [ha]. It hosts dark pine taiga, thin forests, Siberian Dwarf Pine and rhododendron underbrush, subalpine meadows, and alpine tundras. The Baikal Nature Reserve is home to 812 kinds of plants, 49 types of mammals, 272 birds, 3 reptiles, 3 amphibians, and 7 types of fish. The reserve is also home to East Siberian brown bear, Baikal lynx, wolverine, otter, osprey, and golden eagle. The Baikal Nature Reserve is part of the World Network of Biosphere Reserves. The reserve is also a part of the Lake Baikal World Heritage Site. The Kabansky Nature Zakaznik, across 12,100 ha, was transferred under the jurisdiction of the Baikal Nature Reserve in 1985.
By the Lake is a two-part 1969 Soviet film directed by Sergei Gerasimov. In 1971 the USSR State Prize for this film was awarded to Sergei Gerasimov, cinematographer Vladimir Rapoport, art director Pyotr Galadzhev, and the group of leading actors: Oleg Zhakov, Vasily Shukshin, Natalya Belokhvostikova.
The Baikal Deep Underwater Neutrino Telescope (BDUNT) is a neutrino detector conducting research below the surface of Lake Baikal (Russia) since 2003. The first detector was started in 1990 and completed in 1998. It was upgraded in 2005 and again starting in 2015 to build the Baikal Gigaton Volume Detector (Baikal-GVD.) BDUNT has studied neutrinos coming through the Earth with results on atmospheric muon flux. BDUNT picks up many atmospheric neutrinos created by cosmic rays interacting with the atmosphere – as opposed to cosmic neutrinos which give clues to cosmic events and are therefore of greater interest to physicists.
The Corispermoideae are a subfamily of the Amaranthaceae, formerly in family Chenopodiaceae.
Corispermum pallasii, common name Pallas bugseed, is a plant apparently native to Siberia but naturalized in Europe, Canada, and the Great Lakes Region of the United States. It is a branched herb growing on sand dunes and other sandy soils.
Tunkinsky National Park is a national park located in south central Siberia, covers a mountainous region centered on the Irkut River valley that continues from the rift valley of Lake Baikal southwest to the border of Mongolia. To the north and west of the valley is the eastern edge of the Sayan Mountains. To the east are the lower Khamar-Daban mountains. About 1,183,662 hectares in size, the park occupies the entirety of the Tunkinsky District of the Republic of Buryatia. It is about 200 km southwest of the city of Irkutsk.
Pribaikalsky National Park covers the southwest coast of Lake Baikal in southeastern Siberia. The coastal strip includes the lake-facing slopes of the Primorsky Range to the west, as well as offshore islands such as Olkhon Island to the east. It is about 50 km southeast of the city of Irkutsk, Irkutsk Oblast. The park is managed with three other nature reserves, and is a major component of the UNESCO World Heritage Site "Lake Baikal". The Angara River, which is the outflow of Lake Baikal west into the Yenisei River basin, runs through the park. The park has very high levels of biodiversity and endemic species.
Baikalia is a vague geographical term referring to the region around Lake Baikal. It is less common than the concept of Transbaikalia, the area to the east of Lake Baikal. The term Baikalia is loosely defined and has no official definition.
