Chobe National Park is Botswana 's first national park, and also the most biologically diverse . Located in the north of the country, it is Botswana's third largest park, after Central Kalahari Game Reserve and Gemsbok National Park .
55-603: This park is noted for having a population of lions which prey on elephants, mostly calves or juveniles, but also subadults. The original inhabitants of this area were the San bushmen (also known as the Basarwa people in Botswana). They were nomadic hunter-gatherers who were constantly moving from place to place to find food sources, namely fruit, water and wild animals. Nowadays one can find San paintings inside rocky hills of
110-437: A population is often defined as a set of organisms in which any pair of members can breed together. They can thus routinely exchange gametes in order to have usually fertile progeny, and such a breeding group is also known therefore as a gamodeme. This also implies that all members belong to the same species. If the gamodeme is very large (theoretically, approaching infinity), and all gene alleles are uniformly distributed by
165-534: A "decline and fall", as Edward Gibbon put it, of imperial society. Writers taking this line relied heavily on the scandalous behavior of the Julio-Claudian dynasty and the bad emperors reported by Tacitus and other writers and later by the secret history of Procopius , who hated his royal employers to such a degree that he could not contain himself about their real methods and way of life any longer. They, however, spoke elegant Latin. The Protestants changed

What indeed could be expected from this language, at a time when the barbarians had taken possession of Europe, but especially of Italy; when the empire of the east was governed by idiots; when there was a total corruption of morals; when the priests and monks were
275-476: A few programs, most notably the Chinese government's one-child per family policy, have resorted to coercive measures. In the 1970s, tension grew between population control advocates and women's health activists who advanced women's reproductive rights as part of a human rights -based approach. Growing opposition to the narrow population control focus led to a significant change in population control policies in
330-408: A group of human beings with some predefined feature in common, such as location, race , ethnicity , nationality , or religion . In ecology , a population is a group of organisms of the same species which inhabit the same geographical area and are capable of interbreeding . The area of a sexual population is the area where interbreeding is possible between any opposite-sex pair within
385-554: A large empire, Latin tended to become simpler, to keep above all what it had of the ordinary." The origin of the term 'Late Latin' remains obscure. A notice in Harper's New Monthly Magazine of the publication of Andrews' Freund's Lexicon of the Latin Language in 1850 mentions that the dictionary divides Latin into ante-classic, quite classic, Ciceronian, Augustan, post-Augustan and post-classic or late Latin, which indicates
440-460: A non-hunting area, and this area was expanded to 31,600 km (12,200 sq mi) two years later. In 1943, heavy tsetse infestations occurred throughout the region, delaying the creation of the national park. By 1953, the project received governmental attention again: 21,000 km (8,100 sq mi) were suggested to become a game reserve. Chobe Game Reserve was officially created in 1960, though smaller than initially desired. In 1968,
495-579: A second unity of style, infima Latinitas , translated into English as "Low Latin" (which in the one-period case would be identical to media Latinitas ). Du Cange in the glossarial part of his Glossary identifies some words as being used by purioris Latinitatis scriptores , such as Cicero (of the Golden Age). He has already said in the Preface that he rejects the ages scheme used by some: Golden Age, Silver Age, Brass Age, Iron Age. A second category are
550-607: A single area. Governments conduct a census to quantify the size of a resident population within a given jurisdiction. The term is also applied to non-human animals , microorganisms , and plants , and has specific uses within such fields as ecology and genetics . The word population is derived from the Late Latin populatio (a people, a multitude), which itself is derived from the Latin word populus (a people). In sociology and population geography , population refers to
605-510: A single continuous style. Of the two-style interpretations the Late Latin period of Erich Auerbach and others is one of the shortest: "In the first half of the 6th century, which witnessed the beginning and end of Ostrogoth rule in Italy , Latin literature becomes medieval. Boethius was the last 'ancient' author and the role of Rome as the center of the ancient world, as communis patria ,

#1732773216609660-520: A written language, Late Latin is not the same as Vulgar Latin , or more specifically, the spoken Latin of the post Imperial period. The latter served as ancestor of the Romance languages . Although Late Latin reflects an upsurge of the use of Vulgar Latin vocabulary and constructs, it remains largely classical in its overall features, depending on the author who uses it. Some Late Latin writings are more literary and classical, but others are more inclined to
715-407: Is most corrupt. By corrupt, du Cange only meant that the language had resorted to nonclassical vocabulary and constructs from various sources, but his choice of words was unfortunate. It allowed the "corruption" to extend to other aspects of society, providing fuel for the fires of religious (Catholic vs. Protestant) and class (conservative vs. revolutionary) conflict. Low Latin passed from the heirs of
770-609: Is not even known to the nearest million, so there is a considerable margin of error in such estimates. Researcher Carl Haub calculated that a total of over 100 billion people have probably been born in the last 2000 years. Population growth increased significantly as the Industrial Revolution gathered pace from 1700 onwards. The last 50 years have seen a yet more rapid increase in the rate of population growth due to medical advances and substantial increases in agricultural productivity, particularly beginning in
825-611: Is often referred to as the demographic transition . Human population planning is the practice of altering the rate of growth of a human population. Historically, human population control has been implemented with the goal of limiting the rate of population growth. In the period from the 1950s to the 1980s, concerns about global population growth and its effects on poverty, environmental degradation , and political stability led to efforts to reduce population growth rates. While population control can involve measures that improve people's lives by giving them greater control of their reproduction,
880-572: Is understanding what media , "middle", and infima , "low", mean in this context. The term media is securely connected to Medieval Latin by du Cange's own terminology expounded in the Praefatio , such as scriptores mediae aetatis , "writers of the middle age". Du Cange's Glossary takes words from authors ranging from the Christian period (Late Latin) to the Renaissance , dipping into
935-715: Is very likely that the world's population will stop growing before the end of the 21st century. Further, there is some likelihood that population will actually decline before 2100. Population has already declined in the last decade or two in Eastern Europe, the Baltics and in the former Commonwealth of Independent States. The population pattern of less-developed regions of the world in recent years has been marked by gradually declining birth rates. These followed an earlier sharp reduction in death rates. This transition from high birth and death rates to low birth and death rates
990-471: The Holy Roman Empire ) under Charlemagne . Toward the end of his reign his administration conducted some language reforms. The first recognition that Late Latin could not be understood by the masses and therefore was not a lingua franca was the decrees of 813 CE by synods at Mainz , Rheims Tours that from then on preaching was to be done in a language more understandable to the people, which
1045-491: The classical period if a word originated there. Either media et infima Latinitas refers to one age, which must be the middle age covering the entire post-classical range, or it refers to two consecutive periods, infima Latinitas and media Latinitas . Both interpretations have their adherents. In the former case, the infimae appears extraneous; it recognizes the corruptio of the corrupta Latinitas which du Cange said his Glossary covered. The two-period case postulates
1100-407: The inferioris Latinitatis scriptores , such as Apuleius (Silver Age). The third and main category are the infimae Latinitatis scriptores , who must be post-classical; that is, Late Latin, unless they are also medieval. His failure to state which authors are low leaves the issue unresolved. He does, however, give some idea of the source of his infima , which is a classical word, "lowest", of which
1155-485: The vernacular . As such it is an important source of information about changes in the spoken language, while not being a simple replication of the state of the oral language at the time. Also, Late Latin is not identical to Christian patristic Latin, used in the theological writings of the early Christian fathers. While Christian writings used a subset of Late Latin, pagans , such as Ammianus Marcellinus or Macrobius , also wrote extensively in Late Latin, especially in

In 2017 the United Nations Population Division projected that the world's population would reach about 9.8 billion in 2050 and 11.2 billion in 2100. In the future, the world's population is expected to peak at some point, after which it will decline due to economic reasons, health concerns, land exhaustion and environmental hazards. According to one report, it

In Britain, Gildas ' view that Britain fell to the Anglo-Saxons because it was morally slack was already well known to the scholarly world. The northern Protestants now worked a role reversal; if the language was "corrupt", it must be symptomatic of a corrupt society, which indubitably led to
1320-753: The Silver Age and then goes on to define other ages first by dynasty and then by century (see under Classical Latin ). In subsequent editions he subsumed all periods under three headings: the First Period ( Old Latin ), the Second Period (the Golden Age) and the Third Period, "the Imperial Age", subdivided into the Silver Age, the 2nd century, and the 3rd–6th centuries together, which was a recognition of Late Latin, as he sometimes refers to
1375-496: The United States Census Bureau, the world population hit 6.5 billion on 24 February 2006. The United Nations Population Fund designated 12 October 1999 as the approximate day on which world population reached 6 billion. This was about 12 years after the world population reached 5 billion in 1987, and six years after the world population reached 5.5 billion in 1993. The population of countries such as Nigeria

In humans , interbreeding is unrestricted by racial differences, as all humans belong to the same species of Homo sapiens. In ecology, the population of a certain species in a certain area can be estimated using the Lincoln index to calculate the total population of an area based on the number of individuals observed. In genetics,
1485-543: The author. Its origins are obscure, but the Latin expression media et infima Latinitas sprang into public notice in 1678 in the title of a Glossary (by today's standards a dictionary) by Charles du Fresne, sieur du Cange . The multivolume set had many editions and expansions by other authors subsequently. The title varies somewhat; most commonly used was Glossarium Mediae et Infimae Latinitatis . It has been translated by expressions of widely different meanings. The uncertainty
1540-480: The breaking up of a large sexual population (panmictic) into smaller overlapping sexual populations. This failure of panmixia leads to two important changes in overall population structure: (1) the component gamodemes vary (through gamete sampling) in their allele frequencies when compared with each other and with the theoretical panmictic original (this is known as dispersion, and its details can be estimated using expansion of an appropriate binomial equation ); and (2)
1595-459: The comparative degree is inferior , "lower". In the preface, he opposes the style of the scriptores aevi inferioris (Silver Age) to the elegantes sermones , "elegant speech", the high and low styles of Latinitas defined by the classical authors. Apparently, du Cange was basing his low style on sermo humilis , the simplified speech devised by Late Latin Christian writers to address the ordinary people. Humilis (humble, humility) means "low", "of
1650-647: The early 1980s. Late Latin Late Latin is the scholarly name for the form of Literary Latin of late antiquity . English dictionary definitions of Late Latin date this period from the 3rd to 6th centuries AD , and continuing into the 7th century in the Iberian Peninsula . This somewhat ambiguously defined version of Latin was used between the eras of Classical Latin and Medieval Latin . Scholars do not agree exactly when Classical Latin should end or Medieval Latin should begin. Being
1705-514: The early part of the period. Late Latin formed when large numbers of non-Latin-speaking peoples on the borders of the empire were being subsumed and assimilated, and the rise of Christianity was introducing a heightened divisiveness in Roman society, creating a greater need for a standard language for communicating between different socioeconomic registers and widely separated regions of the sprawling empire. A new and more universal speech evolved from

His classification of styles left a century between that event and his final period, the 3rd–6th centuries CE, which was in other systems being considered Late Antiquity. Starting with Charles Thomas Crutwell's A History of Roman Literature from the Earliest Period to the Death of Marcus Aurelius , which first came out in 1877, English literary historians have included
1815-691: The gametes within it, the gamodeme is said to be panmictic. Under this state, allele ( gamete ) frequencies can be converted to genotype ( zygote ) frequencies by expanding an appropriate quadratic equation , as shown by Sir Ronald Fisher in his establishment of quantitative genetics. This seldom occurs in nature: localization of gamete exchange – through dispersal limitations, preferential mating, cataclysm, or other cause – may lead to small actual gamodemes which exchange gametes reasonably uniformly within themselves but are virtually separated from their neighboring gamodemes. However, there may be low frequencies of exchange with these neighbors. This may be viewed as
1870-409: The ground". The Christian writers were not interested in the elegant speech of the best or classical Latin, which belonged to their aristocratic pagan opponents. Instead, they preferred a humbler style lower in correctness, so that they might better deliver the gospel to the vulgus or "common people". Low Latin in this view is the Latin of the two periods in which it has the least degree of purity, or
1925-463: The level of homozygosity rises in the entire collection of gamodemes. The overall rise in homozygosity is quantified by the inbreeding coefficient (f or φ). All homozygotes are increased in frequency – both the deleterious and the desirable. The mean phenotype of the gamodemes collection is lower than that of the panmictic original – which is known as inbreeding depression. It is most important to note, however, that some dispersion lines will be superior to

Under these times of darkness, we must, therefore, rank that Latin, which is called lingua ecclesiastica , and which we cannot read without disgust.

The park can be divided up to 4 areas, each corresponding to one distinct ecosystem : The park is widely known for its large elephant population, estimated to be around 50,000. Elephants living here are Kalahari elephants, the largest in herd size of all known elephant populations.

At that time, a major part of the park's area was classified as crown land . The idea of a national park which would protect the varied local wildlife and promote tourism was first proposed in 1931. The following year, 24,000 km (9,300 sq mi) around Chobe district were officially declared

These settlements were gradually moved out of the park, and it was not until 1975 that the whole protected area was exempt from human activity. Nowadays traces of the prior timber industry are still visible at Serondela. Minor expansions of

Savuti roads, mainly the western Sandridge Road from Mababe Gate and the roads both north and south of the Savuti channel are typically thick sand and tricky to drive. When rain has fallen, driving along the marsh roads carries the risk of getting stuck, as the wet black cotton soil becomes unnavigable. Nogatsaa roads are waterlogged during the wet months and very little of

The Silver Age was extended a century, and the four centuries following made use of Late Latin. Low Latin is a vague and often pejorative term that might refer to any post-classical Latin from Late Latin through Renaissance Latin, depending on

In fact, the concentration is so high throughout Chobe that culls have been considered, but are deemed too controversial and have thus far been rejected by park management.

Thick sand becomes a problem in the Chobe River Front during the dry months, particularly as the temperature rises, while during the wet season
2750-563: The spare century in Silver Latin. Accordingly, the latter ends with the death of the last of the five good emperors in 180 CE. Other authors use other events, such as the end of the Nervan–Antonine dynasty in 192 CE or later events. A good round date of 200 CE gives a canonical list of nearly no overlap. The transition between Late Latin and Medieval Latin is by no means as easy to assess. Taking that media et infima Latinitas

The beginning and end of Imperial Latin is not well defined. Politically, the excluded Augustan Period is the paradigm of imperiality, but the style cannot be grouped with either the Silver Age or with Late Latin. In 6th-century Italy, the Western Roman Empire no longer existed and

In essence, the lingua franca of classical vestiges was doomed when Italy was overrun by the Goths, but its momentum carried it one lifetime further, ending with the death of Boethius in 524 CE.
