Lubbock's nickname, "Hub City," derives from it being the economic, educational, and health-care hub of the multicounty region, north of the Permian Basin and south of the Texas Panhandle, commonly called the South Plains. The area is the largest contiguous cotton-growing region in the world and is heavily dependent on water from the Ogallala Aquifer for irrigation. Lubbock is home to Texas Tech University, the sixth-largest college by enrollment in the state. Hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecosystem
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. ...

Pampatheriidae
Pampatheriidae ("Pampas beasts") is an extinct family of large plantigrade armored armadillos related to extant armadillos in the order Cingulata. However, pampatheriids have existed as a separate lineage since at least the middle Eocene Mustersan age, . Pampatheres evolved in South America during its long period of Cenozoic isolation. Although widespread, they were less diverse and abundant than the armadillos. ''Holmesina'' spread to North America after the formation of the Isthmus of Panama as part of the Great American Interchange. They finally disappeared on both continents in the end-Pleistocene extinctions, about 12,000 years ago. Description Pampatheres are believed to have attained a weight of up to . Like three-banded armadillos, and unlike glyptodonts, their armored shell was given some flexibility by three movable lateral bands of scutes. The osteoderms (bony plates in the skin comprising the armor) of pampatheres were each covered by a single keratinized scute, ...

Armadillo
Armadillos (meaning "little armored ones" in Spanish) are New World placental mammals in the order Cingulata. The Chlamyphoridae and Dasypodidae are the only surviving families in the order, which is part of the superorder Xenarthra, along with the anteaters and sloths. Nine extinct genera and 21 extant species of armadillo have been described, some of which are distinguished by the number of bands on their armor. All species are native to the Americas, where they inhabit a variety of different environments. Armadillos are characterized by a leathery armor shell and long, sharp claws for digging. They have short legs, but can move quite quickly. The average length of an armadillo is about , including its tail. The giant armadillo grows up to and weighs up to , while the pink fairy armadillo has a length of only . When threatened by a predator, ''Tolypeutes'' species frequently roll up into a ball; they are the only species of armadillo capable of this. Etymology The wor ...

Bison
Bison are large bovines in the genus ''Bison'' (Greek: "wild ox" (bison)) within the tribe Bovini. Two extant and numerous extinct species are recognised. Of the two surviving species, the American bison, ''B. bison'', found only in North America, is the more numerous. Although colloquially referred to as a buffalo in the United States and Canada, it is only distantly related to the true buffalo. The North American species is composed of two subspecies, the Plains bison, ''B. b. bison'', and the wood bison, ''B. b. athabascae'', which is the namesake of Wood Buffalo National Park in Canada. A third subspecies, the eastern bison (''B. b. pennsylvanicus'') is no longer considered a valid taxon, being a junior synonym of ''B. b. bison''. References to "woods bison" or "wood bison" from the eastern United States refer to this subspecies, not ''B. b. athabascae'', which was not found in the region. The European bison, ''B. bonasus'', or wisent, or zubr, or colloquially European buff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammoth
A mammoth is any species of the extinct elephantid genus ''Mammuthus'', one of the many genera that make up the order of trunked mammals called proboscideans. The various species of mammoth were commonly equipped with long, curved tusks and, in northern species, a covering of long hair. They lived from the Pliocene epoch (from around 5 million years ago) into the Holocene at about 4,000 years ago, and various species existed in Africa, Europe, Asia, and North America. They were members of the family Elephantidae, which also contains the two genera of modern elephants and their ancestors. Mammoths are more closely related to living Asian elephants than African elephants. The oldest representative of ''Mammuthus'', the South African mammoth (''M. subplanifrons''), appeared around 5 million years ago during the early Pliocene in what is now southern and eastern Africa. Descendant species of these mammoths moved north and continued to propagate into numerous subsequent spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of The United States
The history of the lands that became the United States began with the arrival of Settlement of the Americas, the first people in the Americas around 15,000 BC. Native American cultures in the United States, Numerous indigenous cultures formed, and many saw transformations in the 16th century away from more densely populated lifestyles and towards reorganized polities elsewhere. The European colonization of the Americas began in the late 15th century, however most colonies in what would later become the United States were settled after 1600. By the 1760s, the Thirteen Colonies, thirteen British colonies contained 2.5 million people and were established along the East Coast of the United States, Atlantic Coast east of the Appalachian Mountains. After French and Indian Wars, defeating France, the British government imposed a series of taxes, including the Stamp Act 1765, Stamp Act of 1765, rejecting the colonists' constitutional argument that new taxes needed their approval. ...

Protohistory
Protohistory is a period between prehistory and history during which a culture or civilization has not yet developed writing, but other cultures have already noted the existence of those pre-literate groups in their own writings. For example, in Europe, the Celts and the Germanic tribes are considered to have been protohistoric when they began appearing in Greek and Roman sources. Protohistoric may also refer to the transition period between the advent of literacy in a society and the writings of the first historians. The preservation of oral traditions may complicate matters, as they can provide a secondary historical source for even earlier events. Colonial sites involving a literate group and a nonliterate group are also studied as protohistoric situations. The term can also refer to a period in which fragmentary or external historical documents, not necessarily including a developed writing system, have been found. For instance, the Proto–Three Kingdoms of Korea, the Yayo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceramics Of Indigenous Peoples Of The Americas
Native American pottery is an art form with at least a 7500-year history in the Americas. Pottery is fired ceramics with clay as a component. Ceramics are used for utilitarian cooking vessels, serving and storage vessels, pipes, funerary urns, censers, musical instruments, ceremonial items, masks, toys, sculptures, and a myriad of other art forms. Due to their resilience, ceramics have been key to learning more about pre-Columbian indigenous cultures. Materials and techniques The clay body is a necessary component of pottery. Clay must be mined and purified in an often laborious process, and certain tribes have ceremonial protocols to gathering clay. Different tribes have different processes for processing clay, which can include drying in the sun, soaking in water for days, and repeatedly running through a screen or sieve. Acoma and other Pueblo pottery traditionally pound dry clay into a powder and then remove impurities by hand, then running the dry powder through a screen ...

Archaic Period (North America)
In the classification of the archaeological cultures of North America, the Archaic period in North America, taken to last from around 8000 to 1000 BC in the sequence of North American pre-Columbian cultural stages, is a period defined by the ''archaic stage'' of cultural development. The Archaic stage is characterized by subsistence economies supported through the exploitation of nuts, seeds, and shellfish. As its ending is defined by the adoption of sedentary farming, this date can vary significantly across the Americas. The rest of the Americas also have an Archaic Period. Classifications This classification system was first proposed by Gordon Willey and Philip Phillips in the widely accepted 1958 book ''Method and Theory in American Archaeology''. In the organization of the system, the Archaic period followed the Lithic stage and is superseded by the Formative stage. # The Lithic stage # The Archaic stage # The Formative stage # The Classic stage # The Post-Classic stage ...

Modern World
The term modern period or modern era (sometimes also called modern history or modern times) is the period of history that succeeds the Middle Ages (which ended approximately 1500 AD). This terminology is a historical periodization that is applied primarily to European and Western history. The modern era can be further divided as follows: * The early modern period lasted from c. AD 1500 to 1800 and resulted in wide-ranging intellectual, political and economic change. It brought with it the Age of Enlightenment, the Industrial Revolution and an Age of Revolutions, beginning with those in America and France and later spreading in other countries, partly as a result of upheavals of the Napoleonic Wars. * The late modern period began around 1800 with the end of the political revolutions in the late 18th century and involved the transition from a world dominated by imperial and colonial powers into one of nations and nationhood following the two great world wars, World War I and W ...

Neolithic
The Neolithic period, or New Stone Age, is an Old World archaeological period and the final division of the Stone Age. It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of settlement. It began about 12,000 years ago when farming appeared in the Epipalaeolithic Near East, and later in other parts of the world. The Neolithic lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BC), marked by the development of metallurgy, leading up to the Bronze Age and Iron Age. In other places the Neolithic followed the Mesolithic (Middle Stone Age) and then lasted until later. In Ancient Egypt, the Neolithic lasted until the Protodynastic period, 3150 BC.Karin Sowada and Peter Grave. Egypt in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
