The IUCN Red List Of Threatened Species
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 an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups within th ...

Flora Of The Sierra Madre Del Sur
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 ...

Cloud Forest Flora Of Mexico
In meteorology, a cloud is an aerosol consisting of a visible mass of miniature liquid droplets, ice crystals, frozen crystals, or other particulates, particles, suspended in the atmosphere of a planetary body or similar space. Water or various other chemicals may compose the droplets and crystals. On Earth, clouds are formed as a result of saturation of the air when it is cooled to its dew point, or when it gains sufficient moisture (usually in the form of water vapor) from an adjacent source to raise the dew point to the ambient temperature. Clouds are seen in the Earth's homosphere, which includes the troposphere, stratosphere, and mesosphere. Nephology is the science of clouds, which is undertaken in the cloud physics branch of meteorology. The World Meteorological Organization uses two methods of naming clouds in their respective layers of the homosphere, Latin and common name. Genus types in the troposphere, the atmospheric layer closest to Earth's surface, have Latin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Oaks Of Mexico
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 becomin ...

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] |
Podocarpus Matudae
''Podocarpus matudae'' is a species of conifer in the family Podocarpaceae. It is found in Guatemala, El Salvador, Honduras and Mexico. Description ''Podocarpus matudae'' can form large trees growing to 30 m or more in height, with a trunk diameter of up to 1.5 m."Podocarpus matudae". Tropical Plants Database, Ken Fern. tropical.theferns.info. Accessed 4 April 2022. ropical.theferns.info/viewtropical.php?id=Podocarpus+matudae/ref> The trunk is usually monopodial and erect. Young trees have thin, smooth, light brown-coloured bark which becomes scaly and grey in colour with age and weathering. Branches tend to be spreading or ascendent, with trees forming a large domed crown with age. Branchlets are straight and slender, with fine grooves formed from leaf bases of fallen foliage. The flattened leaves are evergreen and can be lanceolate, straight or slightly falcate in shape, even on the same branchlet and have a leathery texture with a prominent, but narrow midrib.

Quercus Delgadoana
''Quercus delgadoana'' is an endangered species of oak in the family Fagaceae, found in eastern Mexico. It was originally misidentified as other members of the genus ''Quercus'', but was determined as a new species in 2011. Description Individuals of this species are oak trees that grow up to tall and have trunks in diameter. These oaks are often among the tallest trees in the wet montane forests. They are characterized by their thick branchlets and lance-shaped leaves with revolute margins. They bear acorns as fruits and have pistillate flowers on a short stalk, which have 1 or 2 distal flowers. ''Quercus delgadoana'' was determined as a new species because, unlike ''Q. eugeniifolia'' with fruit with annual maturation, this species has fruit with biennial maturation. In addition, this new species can be distinguished from other similar species such as '' Q. laurina'' and ''Q. affinis'' because it has more secondary veins, a revolute blade margin, and an ad ...

Liquidambar Styraciflua
''Liquidambar styraciflua'', commonly known as the American sweetgum among other names, is a deciduous tree in the genus ''Liquidambar'' native to warm temperate areas of eastern North America and tropical montane regions of Mexico and Central America. Sweetgum is one of the main valuable forest trees in the southeastern United States, and is a popular ornamental tree in temperate zone, temperate climates. It is recognizable by the combination of its five-pointed star-shaped leaves (similar to maple leaves) and its hard, spiked fruits. It is currently classified in the plant family (biology), family Altingiaceae, but was formerly considered a member of the Hamamelidaceae. Names This plant's genus name ''Liquidambar'' was first given by Carl Linnaeus, Linnaeus in 1753 from the Latin ('fluid') and the Arabic ('amber'), in allusion to the fragrant terebinthine juice or gum which exudes from the tree. Its botanical name, specific epithet ''styraciflua'' is an old generic name meani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
