Edward Lee Greene
Edward Lee Greene (August 20, 1843–November 10, 1915) was an American botanist known for his numerous publications including the two-part ''Landmarks of Botanical History'' and the describing of over 4,400 species of plants in the American West. Early life Edward Lee Greene was born on August 20, 1843, in Hopkinton, Rhode Island. In 1859 Greene moved to Wisconsin and began studying at Albion Academy, a very reputable institution with a religious emphasis. There Greene met Thure Kumlien, a Swedish naturalist with an interest in botany. Greene accompanied Kumlein on field trips, further developing Greene's interest in botany. In August 1862, Greene joined his father and brothers in joining the 13th Wisconsin Volunteer Infantry Regiment of the Union Army. Though he never rose above the rank of private in his three years of service, Greene was able to advance his botanical studies, collecting specimens as he marched through Tennessee, Kentucky and Alabama. Following his re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ungulate
Ungulates ( ) are members of the diverse clade Euungulata ("true ungulates"), which primarily consists of large mammals with Hoof, hooves. Once part of the clade "Ungulata" along with the clade Paenungulata, "Ungulata" has since been determined to be a polyphyletic and thereby invalid clade based on molecular data. As a result, true ungulates had since been reclassified to the newer clade Euungulata in 2001 within the clade Laurasiatheria while Paenungulata has been reclassified to a distant clade Afrotheria. Living ungulates are divided into two orders: Perissodactyla including Equidae, equines, rhinoceroses, and tapirs; and Artiodactyla including Bos, cattle, antelope, Sus (genus), pigs, giraffes, camels, Ovis, sheep, deer, and Hippopotamidae, hippopotamuses, among others. Cetaceans such as Whale, whales, Dolphin, dolphins, and Porpoise, porpoises are also classified as artiodactyls, although they do not have hooves. Most terrestrial ungulates use the hoofed tips of their toes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Grisea
''Quercus grisea'', commonly known as the gray oak, shin oak or scrub oak, is a North American species deciduous or evergreen shrub or medium-sized tree in the white oak group. It is native to the mountains of the southwestern United States and northern Mexico. It hybridises with four other oak species where the ranges overlap, the Arizona white oak (''Q. arizonica''), the Gambel oak (''Q. gambelii''), the Mohr oak (''Q. mohriana'') and the sandpaper oak (''Q. pungens''). Description ''Quercus grisea'' may grow as a multi-stemmed shrub in drier situations but where the rainfall is sufficient, it grows into a medium size tree of up to about with an irregular crown of twisted branches. The trunk is up to in diameter with light gray bark which is fissured and cracked into small plates. The twigs are stout and a light reddish-brown, covered with grayish down. The leaves are alternate, leathery, long ovate, entire or with a few coarse teeth. They are grayish-gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Arizonica
''Quercus arizonica'', the Arizona white oak, is a North American tree species in the beech family. It is found in Arizona, New Mexico, western Texas, Sonora, Chihuahua, Coahuila, Sinaloa, and Durango. Description The Arizona white oak is one of the largest southwestern oaks. This tree may grow to , with a trunk diameter of . It has stout branches and a spreading crown. The leaves are about long, thick, and evergreen. It grows very slowly once it has become mature, adding approximately of diameter per year. * Bark: color is light grayish. The bark is initially thin and lenticelled, but later becomes quite thick, with shallow fissures and scaly ridges. * Twig: medium-sized, fuzzy. The color can be light brown or reddish brown. Twigs have pointy and fat clusters of terminal buds. * Leaves: alternate, evergreen, simple, and oblong. The color is yellowish green or bluish green. Leaves are usually 1 to 3 in long. The margins are usually entire or toothed, and are rounded a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Havardii
''Quercus havardii'' (common names include shinnery oak, shin oak and Havard oak) is a deciduous, low-growing, thicket-forming shrub that occupies some in the southern Great Plains of North America. Clones may reach hundreds to thousands of years old, although aboveground stems typically live only 11 to 15 years. Shinnery oak stems are usually tall and codominate the plant community with mid- and tall-grasses, which are usually taller than the oaks. The specific epithet honors U.S. Army surgeon and botanist Valery Havard, who contributed much to the knowledge of southwestern plants. The word "shinnery" seems to be derived from '' chêne'' (French for oak), and not from the height of the plant. Description Form: A low shrub to or occasionally a small tree, ''Q. havardii'' forms large clonal thickets by extending rhizomes through the sandy soil where it is usually found. Rhizomes range from in diameter and are concentrated in the upper of soil, although penetration de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Gambelii
''Quercus gambelii'', with the common name Gambel oak, is a deciduous small tree or large shrub that is widespread in the foothills and lower mountains of western North America. It is also regionally called scrub oak, oak brush, and white oak. The common and scientific names, Gambel oak and ''Quercus gambelii'', were named after the American naturalists, naturalist William Gambel (1821–1849). Description ''Quercus gambelii'' trees differ in size from one location to another. The average mature height is from , but occasionally reaches heights of in some locations. Dwarf stands of plants under tall are common in marginal areas where heavy browsing occurs. The largest trees are found along streams in the southern part of its range, and can reach up to 100 feet tall. The champion tree is in Arizona at tall. Although the wood is hard and dense, its branches are irregular and crooked, making them flexible enough to bend without breaking when covered with heavy snow. The B ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Sky Island
Sky islands are isolated mountains surrounded by radically different lowland environments. The term originally referred to those found on the Mexican Plateau and has extended to similarly isolated high-elevation forests. The isolation has significant implications for these natural habitats. Endemism, altitudinal migration, and relict populations are some of the natural phenomena to be found on sky islands. The complex dynamics of species richness on sky islands draws attention from the discipline of biogeography, and likewise the biodiversity is of concern to conservation biology. One of the key elements of a sky island is separation by physical distance from the other mountain ranges, resulting in a habitat island, such as a forest surrounded by desert. Some sky islands serve as refugia for boreal species stranded by warming climates since the last glacial period. In other cases, localized populations of plants and animals tend towards speciation, similar to oceanic isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madrean Sky Islands
The Madrean Sky Islands are enclaves of Madrean pine–oak woodlands, found at higher elevations in a complex of small mountain ranges in southern and southeastern Arizona, southwestern New Mexico, and northwestern Mexico. The sky islands are surrounded at lower elevations by the Sonoran and Chihuahuan deserts. The northern west–east perimeter of the sky island region merges into the higher elevation eastern Mogollon Rim and the White Mountains of eastern Arizona (southern Anasazi region). The Sky Islands are the northernmost of the Madrean pine–oak woodlands, and are classified as part of the Sierra Madre Occidental pine–oak forests ecoregion, of the tropical and subtropical coniferous forests biome. The Sky Islands were isolated from one another and from the pine–oak woodlands of the Sierra Madre Occidental to the south by the warming and drying of the climate since the ice ages. There are approximately 27 Madrean Sky Islands in the United States, and 15 in norther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
