Carnegiea
The saguaro (, ) (''Carnegiea gigantea'') is a tree-like cactus species in the monotypic genus ''Carnegiea'' that can grow to be over tall. It is native to the Sonoran Desert in Arizona, the Mexican state of Sonora, and the Whipple Mountains and Imperial County areas of California. The saguaro blossom is the state wildflower of Arizona. Its scientific name is given in honor of Andrew Carnegie. In 1994, Saguaro National Park, near Tucson, Arizona, was designated to help protect this species and its habitat. Saguaros have a relatively long lifespan, often exceeding 150 years. They may grow their first side arm around 75–100 years of age, but some never grow any arms. Arms are developed to increase the plant's reproductive capacity, as more apices lead to more flowers and fruit. A saguaro can absorb and store considerable amounts of rainwater, visibly expanding in the process, while slowly using the stored water as needed. This characteristic enables the saguaro t ...

Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, ...

Saguaro National Park
Saguaro National Park is an American national park in Pima County, southeastern Arizona. The park consists of two separate areas—the Tucson Mountain District (TMD) about west of the city of Tucson and the Rincon Mountain District (RMD) about east of the city—that preserve Sonoran Desert landscapes, fauna, and flora, including the giant saguaro cactus. The volcanic rocks on the surface of the Tucson Mountain District differ greatly from the surface rocks of the Rincon Mountain District; over the past 30 million years, crustal stretching displaced rocks from beneath the Tucson Mountains of the Tucson Mountain District to form the Rincon Mountains of the Rincon Mountain District. Uplifted, domed, and eroded, the Rincon Mountains are significantly higher and wetter than the Tucson Mountains. The Rincons, as one of the Madrean Sky Islands between the southern Rocky Mountains and the Sierra Madre Oriental in Mexico, support high biodiversity and are home to many plants and anim ...

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 ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andrew Carnegie
Andrew Carnegie (, ; November 25, 1835August 11, 1919) was a Scottish-American industrialist and philanthropist. Carnegie led the expansion of the American steel industry in the late 19th century and became one of the richest Americans in history. He became a leading philanthropist in the United States, Great Britain, and the British Empire. During the last 18 years of his life, he gave away around $350 million (roughly $ billion in ), almost 90 percent of his fortune, to charities, foundations and universities. His 1889 article proclaiming " The Gospel of Wealth" called on the rich to use their wealth to improve society, expressed support for progressive taxation and an estate tax, and stimulated a wave of philanthropy. Carnegie was born in Dunfermline, Scotland, and emigrated to Pittsburgh with his parents in 1848 at age 12. Carnegie started work as a telegrapher, and by the 1860s had investments in railroads, railroad sleeping cars, bridges, and oil derricks. H ...

Tohono Oʼodham
The Tohono Oʼodham (; Oʼodham: ) are a Native American people of the Sonoran Desert, residing primarily in the U.S. state of Arizona and the northern Mexican state of Sonora. The federally recognized tribe is known in the United States as the Tohono Oʼodham Nation. The Tohono Oʼodham Nation, or Tohono Oʼodham Indian Reservation, is a major reservation located in southern Arizona, where it encompasses portions of three counties: Pima, Pinal, and Maricopa in the United States. It also extends into the Mexican state of Sonora. Name The Tohono Oʼodham tribal government and most of the people have rejected the historical name Papago used by European colonizers. They call themselves ''Tohono Oʼodham'', meaning "desert people". The Pima, a competing tribe in this territory, referred to them as ''Ba꞉bawĭkoʼa'', meaning "eating tepary beans". The Spanish colonizers learned that name from the Pima and transliterated it as ''Pápago'', in their pronunciation. European-Ame ...

Pima People
The Pima (or Akimel O'odham, also spelled Akimel Oʼotham, "River People," formerly known as ''Pima'') are a group of Native Americans living in an area consisting of what is now central and southern Arizona, as well as northwestern Mexico in the states of Sonora and Chihuahua. The majority population of the two current bands of the Akimel O'odham in the United States are based in two reservations: the Keli Akimel Oʼodham on the Gila River Indian Community (GRIC) and the On'k Akimel O'odham on the Salt River Pima-Maricopa Indian Community (SRPMIC). The Akimel O'odham are closely related to the Ak-Chin O'odham, now forming the Ak-Chin Indian Community. They are also related to the Sobaipuri, whose descendants reside on the San Xavier Indian Reservation or Wa꞉k (together with the Tohono O'odham), and in the Salt River Indian Community. Together with the related Tohono O'odham ("Desert People") and the Hia C-ed O'odham ("Sand Dune People"), the Akimel O'odham form the Upp ...

Keystone Species
A keystone species is a species which has a disproportionately large effect on its natural environment relative to its abundance, a concept introduced in 1969 by the zoologist Robert T. Paine. Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf, are also apex predators. The role that a keystone species plays in its ecosystem is analogous to the role of a keystone in an arch. While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measures of biomass o ...
