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 ... [...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 sulfate) 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.

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. Today, only the Ray Mine and cemetery are visitable, as the rest of the town has been fenced off due to active mining operations. History The Santa Rita Mountains had been a locale of mining since the mountain range had been part of the Spanish Empire, all the way through to the Gadsden Purchase of 1854, when it became a part of the United States. Although it had always been for silver or gold. This changed in 1875, when Tucson business partners Pinckney Tully and Estevan Ochoa — who were involved in freighting and mining — hauled about 5,000 pounds of copper ore to Tucson to be smelted. Possibly being the first time a significant amount of copper ore was taken from the mountain range. A few years later, Ben Hefti, T.G. Roddick and other claimholders formed the Helvetia Mining District, a ten square mile ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buildings And Structures In Pima County, Arizona
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, 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 separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building practi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protected Areas Of The Sonoran Desert
The Sonoran Desert () is a hot desert and ecoregion in North America 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 Mexico. 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 endemism, endemic plants and animals, notably, the saguaro (''Carnegiea gigantea'') and Stenocereus thurberi, organ pipe cactus (''Stenocereus thurberi''). The Sonoran Desert is clearly distinct from nearby deserts (e.g., the Great Basin Desert, Great Basin, Mojave Desert, Mojave, and Chihuahuan Desert, Chihuahuan deserts) because it provides subtropical warmth in winter and two seasons of rainfall (in contrast, for example, to the Mojave's dry summers ...

Protected Areas Of Pima County, Arizona
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 se ...

Wildlife Areas Of Arizona
Wildlife refers to undomesticated animals and uncultivated plant species which can exist in their natural habitat, 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, incl ...

Biological Stations
Biology is the scientific study of life and living organisms. It is a broad natural science that encompasses a wide range of fields and unifying principles that explain the structure, function, growth, origin, evolution, and distribution of life. Central to biology are five fundamental themes: the cell as the basic unit of life, genes and heredity as the basis of inheritance, evolution as the driver of biological diversity, energy transformation for sustaining life processes, and the maintenance of internal stability (homeostasis). Biology examines life across multiple levels of organization, from molecules and cells to organisms, populations, and ecosystems. Subdisciplines include molecular biology, physiology, ecology, evolutionary biology, developmental biology, and systematics, among others. Each of these fields applies a range of methods to investigate biological phenomena, including observation, experimentation, and mathematical modeling. Modern biology is grounded in ...
