Flora Antarctica
The ''Flora Antarctica'', or formally and correctly ''The Botany of the Antarctic Voyage of H.M. Discovery Ships Erebus and Terror in the years 1839–1843, under the Command of Captain Sir James Clark Ross'', is a description of the many plants discovered on the Ross expedition, which visited islands off the coast of the Antarctic continent, with a summary of the expedition itself, written by the British botanist Joseph Dalton Hooker and published in parts between 1844 and 1859 by Reeve Brothers in London. Hooker sailed on HMS ''Erebus'' as assistant surgeon. The botanical findings of the Ross expedition were published in four parts, the last two in two volumes each, making six volumes in all: * Part I '' Botany of Lord Auckland's Group and Campbell's Island'' (1844–1845) * Part II '' Botany of Fuegia, the Falklands, Kerguelen's Land, Etc.'' (1845–1847) * Part III '' Flora Novae-Zelandiae'' (1851–1853) (2 volumes) * Part IV '' Flora Tasmaniae'' (1853–1859) (2 volumes ...

Johann Hedwig
Johann Hedwig (8 December 1730 – 18 February 1799), also styled as Johannes Hedwig, was a German botanist notable for his studies of 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 ...es. He is sometimes called the "father of bryology". He is known for his particular observations of sexual reproduction in the cryptogams. Many of his writings were in Latin, and his name is rendered in Latin as Ioannis Hedwig or Ioanne Hedwig. Early life Hedwig was born in Brașov, Transylvania, on 8 December 1730. As the son of a shoemaker, he grew up in poverty. It was in his childhood he became fascinated with mosses.Isely, Duane. One Hundred and One Botanists. Purdue University Press, 2002. He went on to study medicine at the University of Leipzig, and received his medical degree in 1759. ...

National Institute Of Polar Research
is the Japanese research institute for Antarctica. This agency manages several research bases on Antarctica. Research centers The NIPR has several research centers on Antarctica topics. Among others there are meteorological, geological, glacier motion, life science, ice dynamics, etc. In 1969, the NIPR started collecting meteorites. Their meteorite collection contains almost 17,000 specimens of meteorites — one of the world's largest meteorite collections. The Antarctic meteorite research in the United States is guided by ANSMET. Antarctic stations * Asuka Station * Dome F * Mizuho Station * Showa Station Planetary science education The NIPR Antarctic Meteorite Research Center loans a set of 30 thin sections of various meteorite types for use in education. The Institute prepared 20 sets of this collection. They were used in several European countries as well, including Hungary, Romania, Denmark, and Belgium. The set includes lunar and Martian meteorites. A ... [...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. Ther ...

Salt Marsh
A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. However, r ...

Pottiaceae
The Pottiaceae are a family of mosses. They form the most numerous moss family known, containing nearly 1500 species or more than 10% of the 10,000 to 15,000 moss species known.

Flora Of The United Kingdom
The flora of Great Britain and Ireland is one of the best documented in the world. There are 1390 native species and over 1100 well-established non-natives documented on the islands. A bibliographic database of the species is compiled by the Botanical Society of Britain and Ireland. Because of the size of the list, it is spread across multiple pages. * Part 1 covers ferns and allies ( Lycopodiopsida, Equisetopsida and Pteridopsida) * Part 2 covers the conifers ( Pinopsida) The remaining parts cover the flowering plants ( Magnoliopsida): * Part 3, covering a group of dicotyledon families (Lauraceae to Salicaceae) * Part 4, covering another group of dicotyledon families (Brassicaceae to Saxifragaceae) * Part 5, covering the dicotyledon family Rosaceae * Part 6, covering another group of dicotyledon families ( Mimosaceae to Dipsacaceae) * Part 7, covering the dicotyledon family Asteraceae * Part 8, covering the monocotyledons ( Butomaceae to Orchidaceae) The list gives an ...

Flora Of Antarctica
Antarctic flora are a distinct community of vascular plants which evolved millions of years ago on the supercontinent of Gondwana. Presently, species of Antarctica flora reside on several now separated areas of the Southern Hemisphere, including southern South America, southernmost Africa, New Zealand, Australia, and New Caledonia. Joseph Dalton Hooker (1817 – 1911) was the first to notice similarities in the flora and speculated that Antarctica had served as either a source or a transitional point, and that land masses now separated might formerly have been adjacent. Based on the similarities in their flora, botanist Ronald D'Oyley Good identified a separate Antarctic Floristic Kingdom that included southern South America, New Zealand, and some southern island groups. In addition, Australia was determined to be its own floristic kingdom because of the influx of tropical Eurasian flora that had mostly supplanted the Antarctic flora and included New Guinea and New Caledonia ...
