Santa Rita Experimental Range And Wildlife Area
The Santa Rita Experimental Range and Wildlife Area is the longest continuously active rangeland research facility and among the five oldest biological field stations in the United States. Located south of Tucson in Pima County, Arizona, the 52,000 acre Santa Rita Experimental Range (SRER) was founded in 1903 and administered by the United States Forest Service until 1987, when the University of Arizona College of Agriculture took over administration of the site. The mission at the SRER is "to advance research and education on the ecology and management of desert rangelands through the secure, long-term access to research areas, state-of-the-art facilities, new discoveries, and research legacies." Environmental data The SRER makes available several spatial and time series data sets for research purposes including monthly resolution precipitation data from 1922 to present, long term vegetation response studies, and livestock grazing histories. Additionally, the SRER maintains a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural Science
Agricultural science (or agriscience for short) is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture. Professionals of the agricultural science are called agricultural scientists or agriculturists. History In the 18th century, Johann Friedrich Mayer conducted experiments on the use of gypsum (hydrated calcium sulphate) as a fertilizer.John Armstrong, Jesse Buel. ''A Treatise on Agriculture, The Present Condition of the Art Abroad and at Home, and the Theory and Practice of Husbandry. To which is Added, a Dissertation on the Kitchen and Garden.'' 1840. p. 45. In 1843, John Bennet Lawes and Joseph Henry Gilbert began a set of long-term field experiments at Rothamsted Research in England, some of which are still running as of 2018. In the United States, a scientific revolution in agriculture began with the Hatch Act of 1887, which used the term " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helvetia, Arizona
Helvetia is a ghost town in Pima County, Arizona, United States that was settled in 1891 and abandoned in the early 1920s. Helvetia is an ancient name for Switzerland. History Helvetia was founded in 1891 for the settlement of workers from the surrounding copper mines. At its peak the city had 300 inhabitants, of which most were Mexicans. At one point, Helvetia had a public school (run by School District No. 14, Pima County). In 1911, the mines closed, due to low commodity prices. The post office, which had opened on December 12, 1899, closed on December 31, 1921, marking the end of the town. The 1967 western film '' Hombre'' was shot in Helvetia. Today There is not much left of Helvetia to see, simply a pair of foundation walls rising above a floor, the ruins of the smelter, and the cemetery. In the vicinity there are slag heaps and shafts from the mines. Although the town is gone, there are several homes in the immediate area that are still in use, including the Helvetia Ra ...

Buildings And Structures In Pima County, Arizona
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protected Areas Of The Sonoran Desert
The Sonoran Desert ( es, Desierto de Sonora) is a desert in North America and ecoregion that covers the northwestern Mexican states of Sonora, Baja California, and Baja California Sur, as well as part of the southwestern United States (in Arizona and California). It is the hottest desert in both Mexico and the United States. It has an area of . In phytogeography, the Sonoran Desert is within the Sonoran Floristic province of the Madrean Region of southwestern North America, part of the Holarctic realm of the northern Western Hemisphere. The desert contains a variety of unique endemic plants and animals, notably, the saguaro (''Carnegiea gigantea'') and organ pipe cactus (''Stenocereus thurberi''). The Sonoran Desert is clearly distinct from nearby deserts (e.g., the Great Basin, Mojave, and Chihuahuan deserts) because it provides subtropical warmth in winter and two seasons of rainfall (in contrast, for example, to the Mojave's dry summers and cold winters). This creates an ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Areas Of Pima County, Arizona
Protection is any measure taken to guard a thing 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 servin ...

Wildlife Areas Of Arizona
Wildlife refers to undomesticated animal species, but has come to include all organisms that grow or live wild in an area without being introduced by humans. Wildlife was also synonymous to game: those birds and mammals that were hunted for sport. Wildlife can be found in all ecosystems. Deserts, plains, grasslands, woodlands, forests, and other areas, including the most developed urban areas, all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that much wildlife is affected by human activities. Some wildlife threaten human safety, health, property, and quality of life. However, many wild animals, even the dangerous ones, have value to human beings. This value might be economic, educational, or emotional in nature. Humans have historically tended to separate civilization from wildlife in a number of ways, including the legal, social, and moral senses. Some a ...

Biological Stations
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific met ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental, Arizona
Continental is a populated place located about south of Tucson, in Pima County, Arizona, near the town of Sahuarita and the retirement community of Green Valley. Once a center for cotton production, Continental is now nearly surrounded by large pecan orchards and Green Valley subdivisions. It is also the closest town to Madera Canyon, a premier birdwatching area and tourist attraction located in the Santa Rita Mountains. History Continental was founded during World War I in 1916, after President Woodrow Wilson asked the Intercontinental Rubber Company of Bernard Baruch, Joseph Kennedy, and J. P. Morgan to grow guayule. Guayule is a plant that produces latex and can be used to make rubber if, as many Americans feared, the German navy were to cut off shipping lanes and imports of rubber from the Far East. In 1916, Intercontinental established the Continental Farm seven miles south of Sahuarita and immediately east of the present-day Green Valley, along the eastern banks of the ...

Madera Canyon (Arizona)
Madera Canyon is a canyon in the northwestern face of the Santa Rita Mountains, twenty-five miles southeast of Tucson, Arizona. As part of the Coronado National Forest, Madera Canyon has campsites, picnic areas, and miles of hiking trails. The canyon is also used as a resting place for migrating birds, and it is thus known as a premier birdwatching area. Madera Canyon was originally named White House Canyon, after a prominent white adobe house was built there in the late 19th century. The canyon was renamed sometime in the early 1900s, although some locals still use the original name. Flora and fauna Madera Canyon is located in the Santa Rita Mountains, which is one of the largest of the Madrean Sky Islands. The canyon and its immediate surroundings are therefore home to wide variety of flora and fauna, ranging from cactus covered desert in the lower reaches of the canyon to aspen and fir forest on Mount Wrightson. With fifteen species of hummingbird, elegant trogon, sulphu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
