Botany Of The Faeroes
{{Use dmy dates, date=January 2022 ''Botany of the Færöes (based upon Danish investigations)'' – a three-volume classic scientific work on flora and vegetation of the Faroe Islands, including fungi, lichens, algae, bryophytes and vascular plants. It was published 1901 to 1908 and funded by the Carlsberg Foundation. The project was initiated by Eugen Warming, who edited the content. The published work was based on investigations made chiefly between 1895 and 1900 by F. Børgesen, C. Jensen, C.H. Ostenfeld, J. Hartz, H. Jónsson and Eug. Warming. Warming, E. ed.

Flora
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteridophytes
A pteridophyte is a vascular plant (with xylem and phloem) that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden. Ferns, horsetails (often treated as ferns), and lycophytes (clubmosses, spikemosses, and quillworts) are all pteridophytes. However, they do not form a monophyletic group because ferns (and horsetails) are more closely related to seed plants than to lycophytes. "Pteridophyta" is thus no longer a widely accepted taxon, but the term ''pteridophyte'' remains in common parlance, as do ''pteridology'' and ''pteridologist'' as a science and its practitioner, respectively. Ferns and lycophytes share a life cycle and are often collectively treated or studied, for example by the International Association of Pteridologists and the Pteridophyte Phylogeny Group. Description Pteridophytes (ferns and lycophytes) are free-sporing vascular plants that have a lif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Sea
The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It spans an area of approximately and is known as the coldest of all the oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanography, oceanographers call it the Arctic Mediterranean Sea. It has been described approximately as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing World Ocean. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N. The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features: the Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's Sea surface temperature, surface temperature and salinity vary seasonally as the Arctic ice ...

Gazet Patursson
Olaf Gazet Patursson (July 6, 1879 – May 2, 1970) was a Faroese gardener and biologist. Gazet Patursson was born in Kirkjubøur, the son of Poul Peder Pedersen (a.k.a. Páll Patursson), a holder of publicly owned land ( fo, kongsbóndi), and Ellen Cathrine (née Djonesen). He was the youngest of the Patursson children, and his siblings Helena, Jóannes, Sverri, Sigert, and Petur were all prominent figures in Faroese society. Although overshadowed by some of his other siblings, Gazet established a reputation as a pioneer in horticulture in the Faroe Islands, specializing in botany and entomology. He established a number of Faroese plant name together with Rasmus Rasmussen.Patursson, Gazet. 1908. List of Popular Plant Names from the Færöes.

Hieracium
''Hieracium'' (), known by the common name hawkweed and classically as (from ancient Greek ιεράξ, 'hawk'), is a genus of flowering plant in the family Asteraceae, and closely related to dandelion (''Taraxacum''), chicory ('' Cichorium''), prickly lettuce (''Lactuca'') and sow thistle (''Sonchus''), which are part of the tribe Cichorieae. Hawkweeds, with their 10,000+ recorded species and subspecies, do their part to make Asteraceae the second largest family of flowering plants. Some botanists group all these species or subspecies into approximately 800 accepted species, while others prefer to accept several thousand species. Since most hawkweeds reproduce exclusively asexually by means of seeds that are genetically identical to their mother plant (apomixis or agamospermy), clones or populations that consist of genetically identical plants are formed and some botanists (especially in UK, Scandinavia and Russia) prefer to accept these clones as good species (arguing t ...

Phytoplankton
Phytoplankton () are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems. The name comes from the Greek words (), meaning 'plant', and (), meaning 'wanderer' or 'drifter'. Phytoplankton obtain their energy through photosynthesis, as do trees and other plants on land. This means phytoplankton must have light from the sun, so they live in the well-lit surface layers (euphotic zone) of oceans and lakes. In comparison with terrestrial plants, phytoplankton are distributed over a larger surface area, are exposed to less seasonal variation and have markedly faster turnover rates than trees (days versus decades). As a result, phytoplankton respond rapidly on a global scale to climate variations. Phytoplankton form the base of marine and freshwater food webs and are key players in the global carbon cycle. They account for about half of global photosynthetic activity and at least half of the oxygen production, despite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( |
Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emil Rostrup
Frederik Georg Emil Rostrup (28 January 1831 – 16 January 1907) was a Danish botanist, mycologist and plant pathologist. Biography Emil Rostrup was born at the village of Stokkemarke on the Danish island of Lolland. Rostrup completed his polyteknisk examen in 1857. From 1858, Rostrup was a teacher at the paedagogical college ''Skårup Seminarium'' in then new subject natural history. He educated to-be school teachers for 25 years. In the meantime he had become well known for his flora handbooks and his works on plant pathology. He was appointed docent at the Royal Veterinary and Agricultural University in 1883. From 1902, he was professor at the same college. Rostrup was first real plant pathologist in Denmark and probably the greatest ever. He was member of Royal Danish Academy of Sciences and Letters (from 1882), Royal Physiographic Society in Lund (from 1888), Royal Swedish Academy of Agriculture and Forestry (from 1890). In 1894, he was made honorary doctor at the Universi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diatom
A diatom (Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Depression, which was once made up of a system of ...

Ernst Østrup
Ernst Vilhelm Østrup (21 September 1845, in Roskilde – 16 April 1917, in Frederiksberg) was a Denmark, Danish botanist and phycology, phycologist, mainly working on diatoms. In 1873 he received his ''cand. polyt.'' degree, and later worked as a schoolteacher in Copenhagen. His diatom research largely dealt with species found in Denmark, Greenland, Iceland, Faeroe Islands and Jan Mayen. The diatom genus ''Oestrupia'' (Heiden) and the species ''Diploneis oestrupii'' (Friedrich Hustedt, Hust.), ''Surirella oestrupii'' (Haaken Hasberg Gran, Gran) and ''Navicula oestrupii'' (Per Teodor Cleve, Cleve) are all named in his honour.
