Maly Yeravna
Maly Yeravna (russian: Малое Еравное; bxr, Бага Ярууна) is a fresh water body in the Yeravninsky District, Buryatia, Russia. There are two inhabited places by the lake, Tuldun in the northwestern shore and Shiringa in the northeastern. The Yeravninsky penitentiary settlement was established by Russian Cossack explorers on the eastern bank of the lake in 1675. But by the beginning of the 18th century the prison had lost relevance and only 11 houses and the former prison clerk hut remained. Geography Maly Yeravna (Little Yeravna) is part of the Yeravna-Khorga Lake System (russian: Еравно-Хоргинской системы озёр), which includes 6 large lakes and a number of smaller ones. It is located at the southwestern end of the lake group, together with Bolshoy Yeravna to the west, separated from it by a narrow landspit. Lake Sosnovo lies further to the southwest and small Lake Khaimisanov to the south. Google Earth The lake is shallow, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitim Plateau
Vitim Plateau is a plateau in Buryatia and Zabaykalsky Krai, Russia. The plateau is sparsely populated, the main settlements are Romanovka and Bagdarin. An area of the plateau is an ancient volcanic field with a number of cinder cones and volcanoes, the last of which was active about 810,000 years before present. The P436 regional road connecting Ulan-Ude and Chita passes through Romanovka across the plateau. Geography The Vitim Plateau lies along the headwaters of the Vitim River, a tributary of the Lena between the Southern Muya Range to the north, the Ikat Range to the west, the Yablonoi Mountains to the south, and in the east with the lower reaches of the Kalakan River to the right bank of the lower reaches of the Karenga River (both Vitim tributaries) and the latter's right tributary, the Bugarikta. The Vitim River begins at the confluence of the China and Vitimkan rivers on the plateau and makes a wide bend around the volcanic zone before flowing northwards. Rive ...

Potamogeton
''Potamogeton'' is a genus of aquatic, mostly freshwater, plants of the family Potamogetonaceae. Most are known by the common name pondweed, although many unrelated plants may be called pondweed, such as Canadian pondweed (''Elodea canadensis''). The genus name means "river neighbor", originating from the Greek ''potamos'' (river) and ''geiton'' (neighbor). Morphology ''Potamogeton'' species range from large (stems of 6 m or more) to very small (less than 10 cm). Height is strongly influenced by environmental conditions, particularly water depth. All species are technically perennial, but some species disintegrate in autumn to a large number of asexually produced resting buds called turions, which serve both as a means of overwintering and dispersal. Turions may be borne on the rhizome, on the stem, or on stolons from the rhizome. Most species, however, persist by perennial creeping rhizomes. In some cases the turions are the only means to differentiate species. The leav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reed (plant)
Reed is a common name for several tall, grass-like plants of wetlands. Varieties They are all members of the order Poales (in the modern, expanded circumscription), and include: In the grass family, Poaceae * Common reed (''Phragmites australis''), the original species named reed * Giant reed (''Arundo donax''), used for making reeds for musical instruments * Burma reed (''Neyraudia reynaudiana'') * Reed canary-grass (''Phalaris arundinacea'') * Reed sweet-grass (''Glyceria maxima'') * Small-reed (''Calamagrostis'' species) In the sedge family, Cyperaceae * Paper reed or papyrus ('' Cyperus papyrus''), the source of the Ancient Egyptian writing material, also used for making boats In the family Typhaceae * Bur-reed (''Sparganium'' species) * Reed-mace (''Typha'' species), also called bulrush or cattail In the family Restionaceae * Cape thatching reed ('' Elegia tectorum''), a restio originating from the South-western Cape, South Africa. * Thatching reed (''Thamnochortus ins ...

Bulrush
Bulrush is a vernacular name for several large wetland grass-like plants *Sedge family (Cyperaceae): **''Cyperus'' **''Scirpus'' **'' Blysmus'' **''Bolboschoenus'' **''Scirpoides'' **''Isolepis'' **''Schoenoplectus'' **''Trichophorum'' *Typhaceae: **''Typha'' The Botanical Society of Britain and Ireland recommends "bulrush" as an English name for plants in the genus ''Typha''. These species are also sometimes known as reedmace, cattails or black paddies. One particular famous story involving bulrushes is that of the ark of bulrushes in the Book of Exodus. In this story, it is said that the infant Moses was found in a boat made of bulrushes. Within the context of the story, this is probably paper reed (''Cyperus papyrus''). See also Rushes (Juncaceae Juncaceae is a family of flowering plants, commonly known as the rush family. It consists of 8 genera and about 464 known species of slow-growing, rhizomatous, herbaceous monocotyledonous plants that may superficially rese ...

Horsetail
''Equisetum'' (; horsetail, snake grass, puzzlegrass) is the only living genus in Equisetaceae, a family of ferns, which reproduce by spores rather than seeds. ''Equisetum'' is a "living fossil", the only living genus of the entire subclass Equisetidae, which for over 100 million years was much more diverse and dominated the understorey of late Paleozoic forests. Some equisetids were large trees reaching to tall. The genus ''Calamites'' of the family Calamitaceae, for example, is abundant in coal deposits from the Carboniferous period. The pattern of spacing of nodes in horsetails, wherein those toward the apex of the shoot are increasingly close together, is said to have inspired John Napier to invent logarithms. Modern horsetails first appeared during the Jurassic period. A superficially similar but entirely unrelated flowering plant genus, mare's tail (''Hippuris''), is occasionally referred to as "horsetail", and adding to confusion, the name "mare's tail" is sometimes ap ...

Arrowhead
An arrowhead or point is the usually sharpened and hardened tip of an arrow, which contributes a majority of the projectile mass and is responsible for impacting and penetrating a target, as well as to fulfill some special purposes such as signaling. The earliest arrowheads were made of stone and of organic materials; as human civilizations progressed, other alloy materials were used. Arrowheads are important archaeological artifacts; they are a subclass of projectile points. Modern enthusiasts still "produce over one million brand-new spear and arrow points per year". A craftman who manufactures arrowheads is called an arrowsmith.Paterson ''Encyclopaedia of Archery'' p. 20 History In the Stone Age, people used sharpened bone, flintknapped stones, flakes, and chips and bits of rock as weapons and tools. Such items remained in use throughout human civilization, with new materials used as time passed. As archaeological artifacts such objects are classed as projectile p ...

Sparganium
''Sparganium'' (bur-reed) is a genus of flowering plants, described as a genus by Linnaeus in 1753. It is widespread in wet areas in temperate regions of both the Northern and Southern Hemispheres. The plants are perennial marsh plants that can grow to 3.5 m (depending on the species), with epicene flowers. It was previously placed alone in the family Sparganiaceae. ''Sparganium'' is closely related to the Typhaceae and the APG III system (2009) includes ''Sparganium'' in that family. It has been determined from phylogenetic analysis to be the closest living relative of the genus '' Typha'' (cat-tail). Summary ''Sparganium'', commonly known as the bur-reed, is a genus of aquatic plants of shallow marshes, ponds and streams. There are 9 species found in the United States and Canada. The stem, which may be floating or emergent, emerges from a buried rhizome, which like many wetland plants, is dependent upon aerenchyma to transport oxygen to the rooting zone. The leaves are st ...

Grass Rush
''Butomus'' is the only known genus in the plant family Butomaceae, native to Europe and Asia. It is considered invasive in some parts of the United States. Taxonomy The Butomaceae family has been recognized by most taxonomists as a plant family; it is sometimes called the "flowering-rush family". The APG II system, of 2003 (unchanged from the APG system, 1998), also recognizes such a family, and places it in the order Alismatales, in the clade monocots. At the ranks of family and order, this is the same placement as in the Cronquist system. However, Cronquist assumed a much smaller order and assigned the order to subclass Alismatidae, in class Liliopsida monocotyledons Species The family counts one species, ''Butomus umbellatus'', or two according to some authorities. *''Butomus umbellatus'' L. - China, Central Asia, Indian Subcontinent, Middle East, Russia, Europe; naturalized in North America North America is a continent in the Nort ...

Phalaris (plant)
''Phalaris'' is a genus of grasses. Various species of ''Phalaris'' grow on every continent except Antarctica. They can be found in a broad range of habitats from below sea level to thousands of feet above sea level and from wet marshy areas to dry places. ''P. arundinacea'' and ''P. aquatica'' are sometimes invasive species in wetlands. Alkaloids Some ''Phalaris'' species contain gramine, which, in sheep and to a lesser extent in cattle, is toxic and can cause brain damage, other organ damage, central nervous system damage, and death. ''Phalaris arundinacea'', ''Phalaris aquatica'', and '' Phalaris brachystachys'' are known to contain the alkaloids DMT, 5-MeO-DMT, and 5-OH-DMT (bufotenin). Some research has been done into the variability of alkaloids in the ''Phalaris'' grasses. Strains with high levels of alkaloids are best avoided in locations with grazing cattle and sheep, due to potential toxicity. Such high-alkaloid strains include ''Phalaris aquatica AQ-1'' and the spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
