Pulicaria Microcephala
''Pulicaria microcephala'' is a species of flowering plant of the family Asteraceae endemic to the Berlengas archipelago in Portugal. It is a small and ramified plant occurring in clearings of scrubs in coastal cliffs. Its flowers are yellow, flowering between March and July. It is an endangered plant species, mainly threatened by the excessive nitrification of soils (due to the high density of seabirds) and invasive plant species, namely the ice plant.

Johan Lange
Johan Martin Christian Lange (20 March 1818 – 3 April 1898) was a prominent Danish botanist. He held the post of Librarian at the Botanical library of the University of Copenhagen from 1851 to 1858. He was Director of the Botanical Garden there from 1856 to 1876, the Reader of botany at the Danish Technical University from 1857 to 1862, and Reader of Botany at the Royal Veterinary and Agricultural University from 1858 to 1893, achieving full professor standing in 1892. He began editing the Flora Danica in 1858, and was its last editor. Together with Japetus Steenstrup, Johan Lange was the publisher of Flora Danica fasc. 44 (1858). Thereafter, he edited alone fasc. 45-51 (1861–83) and Supplement vols 2-3 (1865–74), in total 600 plates. After having finished the publication of Flora Danica, he issued ''Nomenclator Floræ Danicæ'' in 1887 - a volume indexing all planches in Flora Danica alphabetically, systematically and chronologically.

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more t ...

Endemic
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] |
Berlengas
The Berlengas are a Portuguese archipelago consisting of small Atlantic islands off the coast of Peniche, Portugal, in the Oeste region. These islands were traditionally known to British mariners as "the Burlings". The only inhabited island is its largest island, Berlenga Grande, although there is currently no permanent habitation in the archipelago. The other islands are grouped into two groups of islets, the Estelas Islets and the Farilhões-Forcados Islets. History Human occupation on Berlenga Grande dates back to antiquity: the islands are referred to in Ptolemy's ''Geography'' as Λονδοβρίς (''Londobris''). Much later it was referred to as the island of ''Saturno'' by Roman geographers, and was visited successively by Muslims, Vikings and privateers. The islands are thought to be a former sacred place adopted by the Phoenicians in the first millennium BC where the cult of Baal-Melqart was celebrated. In 1513, with the support of Queen Eleanor of Viseu, monks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portugal
Portugal, officially the Portuguese Republic, In recognized minority languages of Portugal: :* mwl, República Pertuesa is a country located on the Iberian Peninsula, in Southwestern Europe, and whose territory also includes the Macaronesian archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, its mainland west and south border with the North Atlantic Ocean and in the north and east, the Portugal-Spain border, constitutes the longest uninterrupted border-line in the European Union. Its archipelagos form two autonomous regions with their own regional governments. On the mainland, Alentejo region occupies the biggest area but is one of the least densely populated regions of Europe. Lisbon is the capital and largest city by population, being also the main spot for tourists alongside Porto, the Algarve and Madeira. One of the oldest countries in Europe, its territory has been continuously settled and fought over since prehistoric tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrification
''Nitrification'' is the biological oxidation of ammonia to nitrite followed by the oxidation of the nitrite to nitrate occurring through separate organisms or direct ammonia oxidation to nitrate in comammox bacteria. The transformation of ammonia to nitrite is usually the rate limiting step of nitrification. Nitrification is an important step in the nitrogen cycle in soil. Nitrification is an aerobic process performed by small groups of autotrophic bacteria and archaea. Microbiology Ammonia oxidation The oxidation of ammonia into nitrite (also known as nitritation) is performed by two groups of organisms, ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA). AOB AOB can be found among the Betaproteobacteria and Gammaproteobacteria. Since discovery of AOA in 2005, two isolates have been cultivated: ''Nitrosopumilus maritimus'' and ''Nitrososphaera viennensis''. In soils the most studied AOB belong to the genera '' Nitrosomonas'' and '' Nitrococcus''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Portugal
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. 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 Thurman ...
