Quail Bush
''Atriplex lentiformis'' (quail bush, big saltbrush, big saltbush, quailbrush, lenscale, len-scale saltbush and white thistle) is a species of saltbush. Distribution ''Atriplex lentiformis'' is native to the southwestern United States and northern Mexico, where it grows in habitats with saline or alkaline soils, such as salt flats and dry lake beds, coastline, and desert scrub. It can also be found in nonsaline soils on riverbanks and woodland. Description ''Atriplex lentiformis'' is a spreading, communal shrub reaching one to three meters in height and generally more in width. It is highly branched and bears scaly or scurfy gray-green leaves up to 5 centimeters long and often toothed or rippled along the edges. This species may be dioecious or monoecious, with individuals bearing either male or female flowers, or sometimes both. Male flowers are borne in narrow inflorescences up to 50 centimeters long, while inflorescences of female flowers are smaller and more compact. Pla ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and 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 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 light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, per ...

Gila River
The Gila River (; O'odham ima Keli Akimel or simply Akimel, Quechan: Haa Siʼil, Maricopa language: Xiil) is a tributary of the Colorado River flowing through New Mexico and Arizona in the United States. The river drains an arid watershed of nearly that lies mainly within the U.S., but also extends into northern Sonora, Mexico. Indigenous peoples have lived along the river for at least 2,000 years, establishing complex agricultural societies before European exploration of the region began in the 16th century. However, European Americans did not permanently settle the Gila River watershed until the mid-19th century. During the 20th century, human development of the Gila River watershed prompted the construction of large diversion and flood control structures on the river and its tributaries, and consequently the Gila now contributes only a small fraction of its historic flow to the Colorado. The historic natural discharge of the river is around , and is now only . These eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Colorado River Valley
The Lower Colorado River Valley (LCRV) is the river region of the lower Colorado River of the southwestern United States in North America that rises in the Rocky Mountains and has its outlet at the Colorado River Delta in the northern Gulf of California in northwestern Mexico, between the states of Baja California and Sonora. This north–south stretch of the Colorado River forms the border between the U.S. states of California/Arizona and Nevada/Arizona, and between the Mexican states of Baja California/Sonora. It is commonly defined as the region from below Hoover Dam and Lake Mead to its outlet at the northern Gulf of California (Sea of Cortez); it includes the Colorado River proper, canyons, the valley, mountain ranges with wilderness areas, and the floodplain and associated riparian environments. It is home to recreation activities from the river, the lakes created by dams, agriculture, and the home of various cities, communities, and towns along the river, or associated ...

Colorado River
The Colorado River ( es, Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico. The river drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora. Known for its dramatic canyons, whitewater rapids, and eleven U.S. National Parks, the Colorado River and its tributaries are a vital source of water for 40 million people.

Prosopis Velutina
''Prosopis velutina'', commonly known as velvet mesquite, is a small to medium-sized tree. It is a legume adapted to a dry, desert climate. Though considered to be a noxious weed in states outside its natural range, it plays a vital role in the ecology of the Sonoran Desert. Distribution The velvet mesquite is native to the Sonoran, Mojave, and Chihuahuan Deserts. It grows at elevations below 4,000 to 5,000 feet in desert grasslands and near washes. The main distribution is in central and southern Arizona and in adjacent Sonora, Mexico. Near waterways, mesquites can form deciduous woodlands called bosques. Description Velvet mesquite can grow to 30–50 ft (9–15 m) tall or more. It grows larger in areas with ample water, smaller in open, dry grasslands. The youngest branches may be green and photosynthetic. Young bark is reddish-brown and smooth. As it matures, it becomes a dark, dusty gray or brown and takes on a shredded texture. Yellow thorns up to one inch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pluchea Sericea
''Pluchea sericea'', commonly called arrowweed or ''cachanilla'' (Mexico), is a rhizomatous evergreen shrub of riparian areas in the lower Sonoran Desert and surrounding areas. It is common in the lower Colorado River valley of California, Nevada and Arizona, as far east as Texas, and in northern Mexico where it often forms dense impenetrable thickets. It is a perennial shrub and grows along watercourses. Uses It was once used medicinally by Native Americans as an antidiarrheal and eyewash. Other traditional uses include thatching, arrowmaking and food, especially the edible root.

Association (ecology)
In phytosociology and community ecology an association is a type of ecological community with a predictable species composition and consistent physiognomy (structural appearance) which occurs in a particular habitat type. The term was first coined by Alexander von Humboldt and formalised by the International Botanical Congress in 1910. An association can be viewed as a real, integrated entity shaped either by species interactions or by similar habitat requirements, or it can be viewed as merely a common point along a continuum. The former view was championed by American ecologist Frederic Clements, who viewed the association as a whole that was more than the sum of its parts, and by Josias Braun-Blanquet, a Swiss-born phytosociologist. On the other end of the argument was American ecologist Henry Gleason, who saw these groupings of plant species as a coincidence produced by the "fluctuation and fortuitous immigration of plants, and an equally fluctuating and variable environment" ...
