Takakiopsida
''Takakia'' is a genus of two species of mosses known from western North America and central and eastern Asia. The genus is placed as a separate family, order and class among the mosses. Discovery ''Takakia'' was discovered in the Himalayas and described by William Mitten in 1861. It was originally described simply as a new liverwort species ('' Lepidozia ceratophylla'') within an existing genus, and it was thus long overlooked. The discovery of similar odd plants in the mid-20th century by Dr. Noriwo Takaki (1915–2006) in Japan sparked more interest. The many unusual features of these plants led to the establishment in 1958 of the species ''Takakia lepidozioides'', in a new genus ''Takakia'', named to honor the man who rediscovered it and recognized its unique characteristics. The species originally described by Mitten was subsequently recognized by Grolle as belonging to this new genus, and accordingly renamed ''Takakia ceratophylla''. All of the plants originally coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moss
Mosses are small, non-vascular plant, non-vascular flowerless plants in the taxonomic phylum, division Bryophyta (, ) ''sensu stricto''. Bryophyta (''sensu lato'', Wilhelm Philippe Schimper, Schimp. 1879) may also refer to the parent group bryophytes, which comprise Marchantiophyta, 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 leaf, leaves that are generally only one cell thick, attached to a plant stem, 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 sporangium, spores. They are typically tall, though some species ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Takakia Ceratophylla
''Takakia ceratophylla'' is one of the two species of toothless mosses in the genus ''Takakia'', under the Takakiaceae family. This species was first described by William Mitten in 1861. ''Takakia ceratophylla'' is vulnerable and threatened by habitat loss due to human activities. Description ''Takakia ceratophylla'' was first described as a liverwort under the genus ''Lepidozia'' for nearly a century. Later rediscovered in Japan and claimed to be sharing traits from both the liverworts and mosses based on genetic sequences and morphological characters. Some features that are similar to mosses include the presence of columella, tapered foot, and calyptra; the elongation and twisting of the seta; and the absence of elaters. Whereas structures such as rhizoids, stomata in sporangium, operculum and peristome teeth are not differentiated in this species. Geographic range and habitat ''Takakia ceratophylla'' is terrestrial and can be found in China, India, Nepal, and the United ...

Takakia Lepidozioides
''Takakia lepidozioides'' is a species of moss in the Takakiaceae family, one of two species of ''Takakia ''Takakia'' is a genus of two species of mosses known from western North America and central and eastern Asia. The genus is placed as a separate family, order and class among the mosses. Discovery ''Takakia'' was discovered in the Himalayas and ...''. Description It is characterized by its tiny bifid leaves in which each segment is only a few cells wide, conspicuous rhizomous shoots, and long leafless stolon shoots which facilitate the colonization of bare areas. A very unusual feature is the lack of male plants within the species, which are thought to have become extinct during an ice age. ''Takakia lepidozioides'' have been found to be a highly adaptive moss. Over the past 65 million years, there have been extreme changes in the climate, however, several molecular adaptations have been observed in this species.Hu, R., Li, X., Hu, Y., Zhang, R., Lv, Q., Zhang, M., She ...

Aleutian Islands
The Aleutian Islands ( ; ; , "land of the Aleuts"; possibly from the Chukchi language, Chukchi ''aliat'', or "island")—also called the Aleut Islands, Aleutic Islands, or, before Alaska Purchase, 1867, the Catherine Archipelago—are a chain of 14 main, larger volcanic islands and 55 smaller ones.

Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...

Sea Level
Mean sea level (MSL, often shortened to sea level) is an mean, average surface level of one or more among Earth's coastal Body of water, bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and Navigation, marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to Calibration, calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. The term ''above sea level'' generally refers to the height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,94 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
