Hobart Muir Smith
Hobart Muir Smith, born Frederick William Stouffer (September 26, 1912 – March 4, 2013), was an Americans, American Herpetology, herpetologist. He is credited with describing more than 100 new species of American reptiles and amphibians. In addition, he has been honored by having at least six species named after him, including the southwestern blackhead snake (''Tantilla hobartsmithi)'', Smith's earth snake (''Uropeltis grandis''), Smith's arboreal alligator lizard (''Abronia smithi)'', Hobart's anadia (''Anadia hobarti)'', Hobart Smith's anole (''Anolis hobartsmithi)'', and Smith's rose-bellied lizard (''Sceloporus smithi)''. At 100 years of age, Smith continued to be an active and productive herpetologist. Although he published on a wide range of herpetological subjects, his main focus throughout his career was on the amphibians and reptiles of Mexico, including taxonomy, bibliographies, and history. Having published more than 1,600 manuscripts, he surpassed all contempor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agave Americana
''Agave americana'', commonly known as the century plant, maguey, or American aloe, is a flowering plant species belonging to the family Asparagaceae. It is native to Mexico and the United States, specifically Texas. This plant is widely cultivated worldwide for its ornamental value and has become naturalized in various regions, including Southern California, the West Indies, South America, the Mediterranean Basin, Africa, the Canary Islands, India, China, Thailand, and Australia. Despite being called "American aloe" in common parlance, ''Agave americana'' is not a member of the same family as ''Aloe'', although it falls under the same order, Asparagales. Description The common name "century plant" stems from its monocarpic nature of flowering only once at the end of its long life. After flowering, the plant dies but produces adventitious shoots from the base, allowing its growth to continue. Although it is called the century plant, it typically lives only 10 to 30 years. ...

Endemic Reptiles 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 becomi ...

Fauna Of The Sierra Madre Oriental
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and ''funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word for a boo ...

Viviparity
In animals, viviparity is development of the embryo inside the body of the mother, with the maternal circulation providing for the metabolic needs of the embryo's development, until the mother gives birth to a fully or partially developed juvenile that is at least metabolically independent. This is opposed to oviparity, where the embryos develop independently outside the mother in eggs until they are developed enough to break out as hatchlings; and ovoviviparity, where the embryos are developed in eggs that remain carried inside the mother's body until the hatchlings emerge from the mother as juveniles, similar to a live birth. Etymology The term "viviparity" and its adjective form "viviparous" both derive from the Latin ''vivus'', meaning "living"; and ''pario'', meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovulipari ...

Pinus Johannis
''Pinus johannis'', the Johann's pine, is a pine in the pinyon pine group, native to North America. The range extends from southeast Arizona and southwest New Mexico, United States, south in Mexico along the Sierra Madre Occidental and the Sierra Madre Oriental to southern Zacatecas and San Luis Potosí. It occurs at moderate to high altitudes, from , in cool, dry climate conditions. Description ''Pinus johannis'' is a small to medium-size tree, often just a shrub, reaching tall and with a trunk diameter of up to . The bark is grey-brown, thin and scaly at the base of the trunk. The leaves ('needles') are in mixed fascicles of three and four, slender, long, and deep green to blue-green, with stomata confined to a bright white band on the inner surfaces.

The cones open to broad wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinus Hartwegii
''Pinus hartwegii'' ( syn. ''P. rudis'', ''P. donnell-smithii''), Hartweg's pine, the Mexican mountain pine, or pino de las alturas, is a pine native to the mountains of Mexico and Central America east to Honduras. It is named after Karl Theodor Hartweg, who described it in 1838. Distribution ''Pinus hartwegii'' is a very high elevation species, growing at elevations of . It forms the alpine tree line on most of Mexico's higher mountains. It grows on both the Sierra Madre Occidental and Sierra Madre Oriental (mountain ranges) (29° North latitude) from Chihuahua State and Nuevo León (26°) to the highest peaks in the mountain ranges on the El Salvador—Honduras border (15° North latitude). In the Sierra Madre Occidental this pine grows with very dry winters and a very heavy rainy season in summer, with constant frosts from October to March. This pine does not acquire the dwarfed and contorted shape shared by many species at high elevation. Even at the alpine tree line, this ...

Dasylirion
''Dasylirion'' is a genus of succulent, rosette-forming plants in the Asparagaceae family (where it is included in the Nolinoideae subfamily). Most species are native to mountainous arid regions of Mexico, with some species also native to the Southwestern United States. The common name sotol is used in English and Spanish to describe various ''Dasylirion'' species, as well as giving its name to sotol, a distilled spirit made from some species of the genus. The genus name ''Dasylirion'' is a compound word coming from the Greek language, Greek δασύς (''dasy)'', meaning ''dense, thick'' or ''shaggy'' and λείριον (''lirion)'', meaning ''lily''. As of November 2024, the genus ''Dasylirion'' includes 23 accepted species. Description Dasylirion are perennial and often long lived plants. With age, most form erect or reclining trunks that vary in height, depending on the species. The leaves blades are long-linear, evergreen and numerous, and are arranged into rosettes, livi ...
