Ulex Argenteus
''Ulex argenteus'' is a species of gorse native to southern Portugal (Algarve and Alentejo) in the Iberian Peninsula. Description ''Ulex argenteus'' is a low-growing shrub with an open branching structure. Branches, stems, and spines are densely covered in short erect hairs, which give the species a silvery colour. Spines are thin and straight or sometimes slightly arched. The calyx is typically 7.5 to 8.5 mm long. Taxonomy and systematics ''Ulex argenteus'' is a diploid species. The diploid '' Ulex canescens'' and the polyploid '' Ulex erinaceus'', and '' Ulex subsericeus'' have been included in ''Ulex argenteus'' in the past, as subspecies or synonyms. However, phylogenetic evidence suggests they are not closely related to ''U. argenteus''. Distribution and habitat The species is distributed in southern Portugal, growing in both metamorphic and calcareous hills. Conservation The species has a narrow distribution range but remains common in suitable habitat. As a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulex
''Ulex'' (commonly known as gorse, furze, or whin) is a genus of flowering plants in the family Fabaceae. The genus comprises about 20 species of thorny evergreen shrubs in the subfamily Faboideae of the pea family Fabaceae. The species are native to parts of western Europe and northwest Africa, with the majority of species in Iberia. Gorse is closely related to the brooms and like them has green stems and very small leaves and is adapted to dry growing conditions. However it differs in its extreme thorniness, the shoots being modified into branched thorns long, which almost wholly replace the leaves as the plant's functioning photosynthetic organs. The leaves of young plants are trifoliate, but in mature plants they are reduced to scales or small spines. All the species have yellow flowers, generally showy, some with a very long flowering season. Species The greatest diversity of ''Ulex'' species is found in the Iberian Peninsula, and most species have narrow distribution ...

Algarve
The Algarve (, , ; from ) is the southernmost NUTS II region of continental Portugal. It has an area of with 467,495 permanent inhabitants and incorporates 16 municipalities ( ''concelhos'' or ''municípios'' in Portuguese). The region has its administrative centre in the city of Faro, where both the region's international airport (IATA: FAO) and public university, the University of Algarve, are located. The region coincides with Faro District and is subdivided into two zones, one to the West ( Barlavento) and another to the East ( Sotavento). Tourism and related activities are extensive and make up the bulk of the Algarve's summer economy. Production of food, which includes fish and other seafood, as well as different types of fruit and vegetables, such as oranges, figs, plums, carob pods, almonds, avocados, tomatoes, cauliflowers, strawberries, and raspberries, are also economically important in the region. Although Lisbon surpasses the Algarve in terms of tourism reve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alentejo
Alentejo ( , ) is a geographical, historical, and cultural region of south–central and southern Portugal. In Portuguese, its name means "beyond () the Tagus river" (''Tejo''). Alentejo includes the regions of Alto Alentejo and Baixo Alentejo. It corresponds to the districts of Beja, Évora, Portalegre, and Alentejo Litoral. Its main cities are Évora, Beja, Sines, Serpa, Estremoz, Elvas, and Portalegre. It has borders with Beira Baixa in the north, with Spain (Andalucia and Extremadura) in the east, Algarve in the south, and the Atlantic Ocean, Ribatejo, and Estremadura in the west. Alentejo is a region known for its traditional polyphonic singing groups, similar to those found in Tuscany, Corsica, and elsewhere. History The comarca of the Alentejo became the Alentejo Province, divided into upper (Alto Alentejo Province) and lower (Baixo Alentejo Province) designations. The modern NUTS statistical region, Alentejo Region, was expropriated from the medieval provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iberian Peninsula
The Iberian Peninsula (), ** * Aragonese and Occitan: ''Peninsula Iberica'' ** ** * french: Péninsule Ibérique * mwl, Península Eibérica * eu, Iberiar penintsula also known as Iberia, is a peninsula in southwestern Europe, defining the westernmost edge of Eurasia. It is principally divided between Spain and Portugal, comprising most of their territory, as well as a small area of Southern France, Andorra, and Gibraltar. With an area of approximately , and a population of roughly 53 million, it is the second largest European peninsula by area, after the Scandinavian Peninsula. Name Greek name The word ''Iberia'' is a noun adapted from the Latin word "Hiberia" originating in the Ancient Greek word Ἰβηρία ('), used by Greek geographers under the rule of the Roman Empire to refer to what is known today in English as the Iberian Peninsula. At that time, the name did not describe a single geographical entity or a distinct population; the same name was us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.

Polyploid
Polyploidy is a condition in which the cells of an organism have more than one pair of ( homologous) chromosomes. Most species whose cells have nuclei ( eukaryotes) are diploid, meaning they have two sets of chromosomes, where each set contains one or more chromosomes and comes from each of two parents, resulting in pairs of homologous chromosomes between sets. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis, the sporophyte generation is diploid and produces spores by ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metamorphic
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distorti ...

Calcareous
Calcareous () is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines. In zoology ''Calcareous'' is used as an adjectival term applied to anatomical structures which are made primarily of calcium carbonate, in animals such as gastropods, i.e., snails, specifically about such structures as the operculum, the clausilium, and the love dart. The term also applies to the calcium carbonate tests of often more or less microscopic Foraminifera. Not all tests are calcareous; diatoms and radiolaria have siliceous tests. The molluscs are calcareous, as are calcareous sponges ( Porifera), that have spicules which are made of calcium carbonate. In botany ''Calcareous grassland'' is a form of grassland characteristic of soils containing much calcium carbonate from underlying chalk or limestone rock. In medicine The term is used in pathology, for example i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
