Senecio Gallicus
''Senecio gallicus'', an annual plant of the genus ''Senecio'' and family Asteraceae, is a species that colonizes isolated habitats with difficult environmental conditions. It is widespread across southern France and the Iberian Peninsula in deserts and xeric shrublands, on steppes and salty dry coastal plains. ''S. gallicus'' is playing a predominant role in shaping patterns of genetic structure by presenting models of historical associations among population rather than patterns of ongoing gene flow. Common names * en, French groundsel * es, Azuzón de Alborán *french: Séneçon de France * it, Senecione gallico Description ''Senecio gallicus'' has had more phylogenetic description because it is an exceptional species among halotypes with a known intraspecific phylogeographic structure which is also species specific. Comparisons of allozyme and chloroplast variation in this species indicate that it persisted in Pleistocene coastal refugia during glaciation periods. ;The ...

Dominique Chaix
"Dominique" is a 1963 French language popular song, written and performed by the Belgian female singer Jeannine Deckers, better known as Sœur Sourire ("Sister Smile" in French) or The Singing Nun. The song is about Saint Dominic, a Spanish-born priest and founder of the Dominican Order, of which she was a member (as Sister Luc-Gabrielle). The English-version lyrics of the song were written by Noël Regney. In addition to French and English, Deckers recorded versions in Dutch, German, Hebrew, Japanese, Korean, and Portuguese. It was a top selling record in 11 countries in late 1963 and early 1964. Commercial performance "Dominique" reached the Top 10 in 11 countries in late 1963 and early 1964, topping the chart in the United States, Canada, Australia and New Zealand. It reached the Top 5 in Norway, Denmark, Ireland and South Africa, with the song making it into the lower reaches of the Top 10 in the Netherlands, West Germany, and the United Kingdom. The song reached and stay ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Almería
Almería (, , ) is a city and municipality of Spain, located in Andalusia. It is the capital of the province of the same name. It lies on southeastern Iberia on the Mediterranean Sea. Caliph Abd al-Rahman III founded the city in 955. The city grew wealthy during the Islamic era, becoming a world city throughout the 11th and 12th centuries. It enjoyed an active port that traded silk, oil and raisins. Etymology The name "Almería" comes from the city's former Arabic name, ''Madīnat al-Mariyya'', meaning "city of the watchtower". As the settlement was originally port or coastal suburb of Pechina, it was initially known as ''Mariyyat al-Bajjāna'' (''Bajjāna'' being the Arabic name for Pechina). History The origin of Almería is connected to the 9th-century establishment of the so-called Republic of Pechina (Bajjana) some kilometres to the north, which was for a time autonomous from the Cordobese central authority: the settlement of current-day Almería initially developed as ...

Extrusive
Extrusive rock refers to the mode of igneous volcanic rock formation in which hot magma from inside the Earth flows out (extrudes) onto the surface as lava or explodes violently into the atmosphere to fall back as pyroclastics or tuff. In contrast, intrusive rock refers to rocks formed by magma which cools below the surface.Jain, Sreepat (2014). ''Fundamentals of Physical Geology''. New Delhi, India: Springer. . The main effect of extrusion is that the magma can cool much more quickly in the open air or under seawater, and there is little time for the growth of crystals. Sometimes, a residual portion of the matrix fails to crystallize at all, instead becoming a natural glass or obsidian. If the magma contains abundant volatile components which are released as free gas, then it may cool with large or small vesicles (bubble-shaped cavities) such as in pumice, scoria, or vesicular basalt. Other examples of extrusive rocks are rhyolite and andesite. Texture The texture of ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Hectares
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, is ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isla De Alborán
Alboran Island ( es, Isla de Alborán) is a small islet of Spain ( province of Almería) in the Alboran Sea, part of the western Mediterranean Sea, about north of the Moroccan coast and from the Spanish mainland. The main buildings are an automated lighthouse built in the 19th century, a small cemetery, and a harbor. Description The island is a flat platform about above sea level and about in area. off the northeastern end of the island is the small ''islote de La Nube'' (literally, islet of the cloud). Natural history Alboran has a volcanic origin, located in an important seismic zone where the African plate collides with the Eurasian plate. In 1899 a new igneous rock was discovered on Alboran, with the name of alboranite, in honor of the island. The islet has been recognised as an Important Bird Area (IBA) by BirdLife International because it supports a breeding population of Audouin's gulls, as well as various species of passerines on migration.

Endemism
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] |
Glacial Period
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period ...
