Jean Louis Marie Poiret
Jean Louis Marie Poiret (11 June 1755 in Saint-Quentin, Aisne, Saint-Quentin7 April 1834 in Paris) was a French clergyman, Botany, botanist, and Exploration, explorer. From 1785 to 1786, he was sent by Louis XVI of France, Louis XVI to Algeria to study the flora. After the French Revolution, he became a professor of natural history at the Grandes écoles, Écoles Centrale of Aisne. The genus ''Poiretia (plant), Poiretia'' of the legume family Fabaceae was named after him in 1807 by Étienne Pierre Ventenat.

Daniel Solander
Daniel Carlsson Solander or Daniel Charles Solander (19 February 1733 – 13 May 1782) was a Sweden, Swedish naturalist and an Apostles of Linnaeus, apostle of Carl Linnaeus. Solander was the first university-educated scientist to set foot on Australia, Australian soil. Biography Solander was born in Piteå, Norrbotten, Sweden, to Rev. Carl Solander a Lutheran principal, and Magdalena (née Bostadia). Solander enrolled at Uppsala University in July 1750 and initially studied languages, the humanities and law. The professor of botany was the celebrated Carl Linnaeus, who was soon impressed by young Solander's ability and accordingly persuaded his father to let him study natural history. Solander travelled to England in June 1760 to promote the new Linnean system of classification. In February 1763, he began librarian, cataloguing the natural history collections of the British Museum, and was elected a Fellow of the Royal Society in June the following year. In 1768, Solander g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Macaronesia
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...

Flora Of Madeira
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'' for purposes of specificity. 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 ...

Ilex
''Ilex'' () or holly is a genus of over 570 species of flowering plants in the family Aquifoliaceae, and the only living genus in that family. ''Ilex'' has the most species of any woody dioecious angiosperm genus. The species are evergreen or deciduous trees, shrubs, and climbers from tropics to temperate zones worldwide. The type species is ''Ilex aquifolium'', the common European holly used in Christmas decorations and cards. Description The genus is widespread throughout the temperate and subtropical regions of the world. It includes species of trees, shrubs, and climbers, with evergreen or deciduous foliage and inconspicuous flowers. Its range was more extended in the Tertiary period and many species are adapted to laurel forest habitats. It occurs from sea level to more than with high mountain species. It is a genus of small, evergreen trees with smooth, glabrous, or pubescent branchlets. The plants are generally slow-growing with some species growing to tall. The type ...

Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...

Laurisilva
Laurel forest, also called laurisilva or laurissilva, is a type of subtropical forest found in areas with high humidity and relatively stable, mild temperatures. The forest is characterized by broadleaf tree species with evergreen, glossy and elongated leaves, known as "laurophyll" or "lauroid". Plants from the laurel family (Lauraceae) may or may not be present, depending on the location. Ecology Laurel and laurophyll forests have a patchy distribution in warm temperate regions, often occupying topographic refugia where the moisture from the ocean condenses so that it falls as rain or fog and soils have high moisture levels.Abstract at NASA – MODIS: Izquierdo, T; de las Heras, P; Marquez, A (2011).

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Holly
''Ilex aquifolium'', the holly, common holly, English holly, European holly, or occasionally Christmas holly, is a species of flowering plant in the family (botany), family Aquifoliaceae, native plant, native to western and southern Europe, northwest Africa, and southwest Asia.Flora Europaea''Ilex aquifolium''/ref>Med-Checklist''Ilex aquifolium''/ref>Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins .Flora of NW Europe''Ilex aquifolium'' It is regarded as the type species of the genus ''Holly, Ilex'', which by association is also called "holly". It is an evergreen tree or shrub found, for example, in shady areas of forests of oak and in beech hedges. In the British Isles it is one of very few native hardwood evergreen trees. It has a great capacity to adapt to different conditions and is a pioneer species that repopulates the margins of forests or clearcuts. ''I. aquifolium'' can exceed 10 m in height, but is often found at much smaller heights, typically tall and b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
