Pseudotsuga Menziesii Var. Glauca
''Pseudotsuga menziesii'' var. ''glauca'', or Rocky Mountain Douglas-fir, is an evergreen conifer native to the interior mountainous regions of western North America, from central British Columbia and southwest Alberta in Canada southward through the United States to the far north of Mexico. The range is continuous in the northern Rocky Mountains south to eastern Washington, eastern Oregon, Idaho, western and south-central Montana and western Wyoming, but becomes discontinuous further south, confined to " sky islands" on the higher mountains in Utah, Colorado, Arizona and New Mexico, with only very isolated small populations in eastern Nevada, westernmost Texas, and northern Mexico. It occurs from 600 m altitude in the north of the range, up to 3,000 m, rarely 3,200 m, in the south. Further west towards the Pacific coast, it is replaced by the related coast Douglas-fir (''Pseudotsuga menziesii'' var. ''menziesii''), and to the south, it is replaced by Mexican Dougl ...

Pike National Forest
The Pike National Forest is located in the Front Range of Colorado, United States, west of Colorado Springs including Pikes Peak. The forest encompasses 1,106,604 acres (4,478 km2) within Clear Creek, Teller, Park, Jefferson, Douglas and El Paso counties. The major rivers draining the forest are the South Platte and Fountain Creek. Rampart Reservoir is a large artificial body of water located within the forest. The forest is named after American explorer Zebulon Pike. Much of the bedrock within Pike National Forest is made up of the coarse, pink to orange Pikes Peak granite. Administration Pike National Forest is managed in association with San Isabel National Forest and Comanche National Grassland in Colorado, as well as Cimarron National Grassland in Kansas and is headquartered in Pueblo, Colorado. There are local ranger district offices located in Colorado Springs, Fairplay and Morrison. Forest fires The dry climate of Pike National Forest makes it prime wi ...

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infraspecific Name (botany)
In botany, an infraspecific name is the scientific name for any taxon below the rank of species, i.e. an infraspecific taxon or infraspecies. (A "taxon", plural "taxa", is a group of organisms to be given a particular name.) The scientific names of botanical taxa are regulated by the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN). This specifies a 'three part name' for infraspecific taxa, plus a 'connecting term' to indicate the rank of the name., Art. 24 An example of such a name is ''Astrophytum myriostigma'' subvar. ''glabrum'', the name of a subvariety of the species ''Astrophytum myriostigma'' (bishop's hat cactus). Names below the rank of species of cultivated kinds of plants and of animals are regulated by different codes of nomenclature and are formed somewhat differently. Construction of infraspecific names Article 24 of the ICN describes how infraspecific names are constructed. The order of the three parts of an infraspecific name is: :genus ...

Postglacial
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global sig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variety (biology)
In botanical nomenclature, variety (abbreviated var.; in la, varietas) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, '' Escobaria vivipara'' (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. See also ''Capsicum annuum var. glabriusculum'' Definitions The term is defined in different ways by different authors. However, the ...

Pseudotsuga Menziesii Var
''Pseudotsuga'' is a genus of evergreen coniferous trees in the family Pinaceae (subfamily Laricoideae). Common names for species in the genus include Douglas fir, Douglas-fir, Douglas tree, Oregon pine and Bigcone spruce. ''Pseudotsuga menziesii'' (Douglas fir proper) is widespread in western North America and is an important source of timber. The number of species has long been debated, but two in western North America and two to four in eastern Asia are commonly acknowledged. Nineteenth-century botanists had problems in classifying Douglas firs, due to the species' similarity to various other conifers better known at the time; they have at times been classified in ''Pinus'', ''Picea'', ''Abies'', ''Tsuga'', and even '' Sequoia''. Because of their distinctive cones, Douglas firs were finally placed in the new genus ''Pseudotsuga'' (meaning "false hemlock") by the French botanist Carrière in 1867. The genus name has also been hyphenated as ''Pseudo-tsuga''. Name The tree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mexican Douglas-fir
''Pseudotsuga menziesii var. lindleyana'', commonly known as the Mexican Douglas-fir, is a conifer in the genus '' Pseudotsuga'' that is endemic to Mexico. DNA sequence and morphological evidence suggests it is most closely related to Rocky Mountain Douglas-fir (''P. menziesii'' var. ''glauca'') and might best be treated as an additional variety within '' P. menziesii''. Distribution ''Pseudotsuga menziesii var. lindleyana'' is native to the Sierra Madre Occidental, Sierra Madre Oriental, and scattered mountains as far south as Oaxaca. The Mexican Government lists Mexican Douglas-fir as "subject to special protection" because its populations are small, isolated and show signs of low fertility and recruitment due to inbreeding depression Inbreeding depression is the reduced biological fitness which has the potential to result from inbreeding (the breeding of related individuals). Biological fitness refers to an organism's ability to survive and perpetuate its genetic mater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
