Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Protected Areas Of The Mojave Desert
Protection is any measure taken to guard something against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage ser ...

Interstate 40 In California
Interstate 40 (I-40) is a major east–west Interstate Highway in the United States, stretching from Barstow, California, to Wilmington, North Carolina. The segment of I-40 in California is sometimes called the Needles Freeway. It passes through the eastern fringe of the Inland Empire metropolitan area, going east from its western terminus at I-15 in Barstow across the Mojave Desert in San Bernardino County past the Clipper Mountains to Needles, before it crosses over the Colorado River into Arizona east of Needles. All of I-40 in California are in San Bernardino County. Route description The entirety of I-40 in California is designated as Route 40 in the state highway system. The California Streets and Highways Code defines it as follows in section 340: "Route 40 is from Route 15 at Barstow to the Arizona state line near Topock, Arizona via Needles." I-40 goes through the Mojave Desert on the entirety of its run through California. The highway starts its eastwar ...

Endemism
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 b ...

Manzanita
Manzanita is a common name for many species of the genus '' Arctostaphylos''. They are evergreen shrubs or small trees present in the chaparral biome of western North America, where they occur from Southern British Columbia and Washington to Oregon, California, Utah, Arizona, New Mexico, and Texas in the United States, and throughout Mexico. Manzanitas can live in places with poor soil and little water. They are characterized by smooth orange or red bark and stiff, twisting branches. There are 107 species and subspecies of manzanita, 95 of which are found in the Mediterranean climate and colder mountainous regions of California, ranging from ground-hugging coastal and mountain species to small trees up to 20 feet (6m) tall. Manzanitas bloom from winter to early spring and carry berries in spring and summer. The berries and flowers of most species are edible. The word ''manzanita'' is the Spanish diminutive of ''manzana'' meaning "little apple". The name manzanita is also somet ...

Juniperus Californica
''Juniperus californica'', the California juniper, is a species of juniper native to southwestern North America. Description ''Juniperus californica'' is a shrub or small tree reaching , but rarely up to tall. The bark is ashy gray, typically thin, and appears to be "shredded". The shoots are fairly thick compared to most junipers, between in diameter. The foliage is bluish-gray and scale-like. The juvenile leaves (on the seedlings) are needle-like and long. Arranged in opposite decussate pairs or whorls of three, the adult leaves are scale-like, long on lead shoots and broad. The cones are berrylike, in diameter, blue-brown with a whitish waxy bloom, turning reddish-brown, and contain a single seed (rarely two or three). The seeds are mature in about 8 or 9 months. The male cones are long and shed their pollen in early spring. This juniper is largely dioecious, producing cones of only one sex, but around 2% of plants are monoecious, with both sexes on the same plant. ...

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 ...
