Orthodontopsis Bardunovii
''Orthodontopsis bardunovii'' is a species of moss in the family Orthodontiaceae. It is endemic to Russia, where it is known only from the Altai and Sayan Mountains. It grows on rotting logs in forested habitat and it is threatened by deforestation Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated d ....

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...

Orthodontiaceae
Orthodontiaceae is a family of mosses. Description Species in the family are acrocarpous or pseudo- pleurocarpous mosses that are epiphytic. They are usually dioecious and have erect setae and capsules with a well-developed operculum. They are characterized as small plants growing loosely on coniferous trees, decaying coniferous wood, or in terrestrial habitats. Species are widespread in tropical and temperate regions.P. M. Eckel. 2014. Orthodontiaceae. In Flora of North America. Vol. 28: 113-116 Classification The placement of the family has been subject to much revision. The genus '' Orthodontium'' was elevated to family status by W. R. Buck and Goffinet (2000) and was originally associated with the Bryales. The family was elevated the order Orthodontiales by Bell et al. (2007).Bell, N., Quandt, D., O'Brien, T., & Newton, A. (2007).

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Altai Mountains
The Altai Mountains (), also spelled Altay Mountains, are a mountain range in Central Asia, Central and East Asia, where Russia, China, Mongolia and Kazakhstan converge, and where the rivers Irtysh and Ob River, Ob have their headwaters. The massif merges with the Sayan Mountains in the northeast, and gradually becomes lower in the southeast, where it merges into the high plateau of the Gobi Desert. It spans from about 45° to 52° N and from about 84° to 99° E. The region is inhabited by a sparse but ethnically diverse population, including Russian people, Russians, Kazakh people, Kazakhs, Altai people, Altais, Mongol people, Mongols and Volga Germans, though predominantly represented by indigenous ethnic minorities of semi-nomadic stock. The local economy is based on bovine, sheep, horse animal husbandry, husbandry, hunting, agriculture, forestry, and mining. The Altaic languages, Altaic language family takes its name from this mountain range. Etymology and modern names ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sayan Mountains
The Sayan Mountains (russian: Саяны ''Sajany''; mn, Соёны нуруу, ''Soyonï nurû''; otk, 𐰚𐰇𐰏𐰢𐰤, Kögmen) are a mountain range in southern Siberia, Russia (Buryatia, Irkutsk Oblast, Krasnoyarsk Krai, Tuva Republic and Khakassia) and northern Mongolia. In the past, it served as the border between Mongolia and Russia. The Sayan Mountains' towering peaks and cool lakes southwest of Tuva give rise to the tributaries that merge to become one of Siberia's major rivers, the Yenisei River, which flows north over 3,400 kilometres (2000 mi) to the Arctic Ocean. This is a protected and isolated area, having been kept closed by the Soviet Union since 1944. Geography Western Sayan At 92°E the Western Sayan system is pierced by the Ulug-Khem (russian: Улуг-Хем) or Upper Yenisei River, and at 106°, at its eastern extremity, it terminates above the depression of the Selenga-Orkhon Valley. It stretches almost at a right angle to the Western Sayan fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...

Endangered Plants
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 3654 endangered plant species. 17% of all evaluated plant species are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as '' data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
