Sphagnum Magellanicum
''Sphagnum magellanicum'', commonly called Magellanic bogmoss, Magellan's sphagnum, Magellan's peatmoss or midway peat moss, is a widespread species of moss found in wet boreal forest in the far south and southwest of South America, North America and Eurasia. Description The red-purple colour visible all or parts of the leaves is very distinctive. It forms low cushions and mats within freshwater bogs. Conservation In the 2010s ''Sphagnum'' peat in Chile has begun to be harvested at large scales for export to countries like Japan, South Korea, Taiwan and the United States. Given ''Sphagnum''s property to absorb excess water and release it during dry months harvesting of ''Sphagnum'', means that overexploitation may threaten the water supply in the fjords and channels of Chile. Extraction of ''Sphagnum'' in Chile is regulated by law since August 2, 2018. Since 2018 Chilean law allows only for the manual extraction of Sphagnum using only pitchforks or similar tools as aid.

Samuel Elisée Bridel-Brideri
Samuel Elisée Bridel-Brideri (28 November 1761 in Crassier, Vaud – 7 January 1828) was a Swiss-German bryologist. He studied at the University of Lausanne, and at the age of 19 began work as a tutor to the princes of Saxe-Gotha-Altenburg. In 1804 he was appointed ''Geheimer Legationsrath'' to the Privy Council, and later on, he worked as a librarian in the city of Gotha. He was the author of an important work on mosses titled ''Muscologia recentiorum'' (1797-1803), of which several supplements were issued in the ensuing years. Later on, he published the two-volume ''Bryologia universa'' (1826–27), which was an improved edition of his earlier work. In the latter work he introduced a new system for classification of mosses; a system that is no longer used. The genus ''Bridelia'' was named in his honor by German botanist Carl Ludwig Willdenow (1765-1812). A portion of his herbarium is now housed at the Berlin Botanical Museum, and a number of his scientific papers are ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Boreal Forest
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. The taiga of North America is mostly spruce, Scandinavian and Finnish taiga consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overexploitation
Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife. In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at an unsustainable rate, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology, the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. The term is also used and defined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fjords And Channels Of Chile
The southern coast of Chile presents a large number of fjords and fjord-like channels from the latitudes of Cape Horn (55° S) to Reloncaví Estuary (42° S). Some fjords and channels are important navigable channels providing access to ports like Punta Arenas, Puerto Chacabuco and Puerto Natales. History Indigenous peoples The earliest known inhabitants of the fjords and channels were, from north to south, the Chono, Alacalufe and Yaghan, all of whom shared a life style as canoe-faring hunter-gatherers. They also shared physical traits such as being of low stature, long-headed (''Dolichocephalic''), and having a "low face".Trivero Rivera 2005, p. 42. Despite similarities their languages were completely different.Trivero Rivera 2005, p. 33. The Chono moved around in the area from Chiloé Archipelago to 50° S and the Alacalufe from 46° S to the Strait of Magellan. Thus both groups overlapped in Gulf of Penas, Guayaneco Archipelago and other islands. Yaghans inhabited a reduced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magallanes Region
The Magallanes Region (), officially the Magallanes y la Antártica Chilena Region ( es, Región de Magallanes y de la Antártica Chilena), is one of Chile's 16 first order administrative divisions. It is the southernmost, largest, and second least populated region of Chile. It comprises four provinces: Última Esperanza, Magallanes, Tierra del Fuego, and Antártica Chilena. Magallanes's geographical features include Torres del Paine, Cape Horn, Tierra del Fuego island, and the Strait of Magellan. It also includes the Antarctic territory claimed by Chile. Despite its large area, much of the land in the region is rugged or closed off for sheep farming, and is unsuitable for settlement. 80% of the population lives in the capital Punta Arenas, a major market city and one of the main hubs for Antarctic exploration. The main economic activities are sheep farming, oil extraction, and tourism. It is also the region with the lowest poverty level in Chile (5.8%); households in Magal ...

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...
