75-544: The Ayoreo people are known by numerous names including Ayoré, Ayoreode, Guarañoca, Koroino, Moro, Morotoco, Poturero, Pyeta Yovai, Samococio, Sirákua, Takrat, Yanaigua and Zapocó. In the Ayoreo language, Ayoreo means “true people,” and Ayoreode means "human beings." They speak the Ayoreo language , which is classified under Zamucoan , a small language family of Paraguay and Bolivia. A grammar and dictionary have been published for

150-679: A warlike tribe that expanded along the Tapajós river and its tributaries and were feared by neighboring tribes. In the early 19th century, the Munduruku were pacified and subjugated by the Brazilians. During the Amazon rubber boom it is estimated that diseases brought by immigrants, such as typhus and malaria , killed 40,000 native Amazonians. In the 1950s, Brazilian explorer and defender of indigenous people, Cândido Rondon , supported

225-596: A baby is born to a woman who is not in an established relationship. The Ayoreo were traditionally organized into over 50 autonomous, flexible local groups. The most widely known group is the Totobiegosode (people from the place where collared peccaries ate their gardens). Other groups include the Garaigosode (those who live in the lowlands), the Tacheigosode (the people from the region of abundant agouti),

300-721: A complex civilization was flourishing along the Amazon in the 1540s. The Pre-Columbian agriculture in the Amazon Basin was sufficiently advanced to support prosperous and populous societies. It is believed that civilization was later devastated by the spread of diseases from Europe, such as smallpox . This civilization was investigated by the British explorer Percy Fawcett in the early twentieth century. The results of his expeditions were inconclusive, and he disappeared mysteriously on his last trip. His name for this lost civilization

375-501: A great risk of contact, and can displace the people living there. Seventeen Ayoreo-Totobiegosode people made contact in 2004 due to extensive deforestation in their territory and are now in a stage of initial contact. The group called themselves Areguede’urasade, meaning the band of Areguede. While they were living in the forest, they struggled to avoid contact, forced to flee from any sign of outsiders and had to communicate by whistles to keep from being heard. They sometimes had to camp in

450-422: A hazard. Among the largest predatory creatures are the black caiman , jaguar , cougar , and anaconda . In the river, electric eels can produce an electric shock that can stun or kill, while piranha are known to bite and injure humans. Various species of poison dart frogs secrete lipophilic alkaloid toxins through their flesh. There are also numerous parasites and disease vectors. Vampire bats dwell in

525-433: A long time, it was thought that the Amazon rainforest was never more than sparsely populated, as it was impossible to sustain a large population through agriculture given the poor soil. Archeologist Betty Meggers was a prominent proponent of this idea, as described in her book Amazonia: Man and Culture in a Counterfeit Paradise . She claimed that a population density of 0.2 inhabitants per square kilometre (0.52/sq mi)

600-529: A result of their treatment after contact. In Bolivia, the Ayoreo people are represented by the organization CANOB (Central Ayorea Nativa del Oriente Boliviano). CANOB has its main office in Santa Cruz de la Sierra. CANOB has four titles to Native Community Lands , whose populations range from 157 to 384 people. In 2002 an Ayoreo organization was founded in Paraguay, UNAP (Unión Nativa Ayoreo del Paraguay or

675-405: Is a fusional language. Verbs agree with their subjects, but there is no tense-inflection. Consider the following paradigm, which has prefixes marking person and suffixes marking number: When the verb root contains a nasal, there are nasalized variants of the agreement affixes: Ayoreo is a mood-prominent language. Nouns can be divided into possessable and non-possessable; possessor agreement

750-500: Is a need for scholarships in hopes that education will allow them to escape the current poverty. Members sometimes turn to begging or prostitution in order to survive. Ayoreo prostitutes are at a high risk for HIV, and they sometimes hide their condition and do not seek treatment in order to avoid discrimination from their community. The Ayoreo often live in settlements together, such as the Degüi Community in Santa Cruz. However,

825-811: Is believed that the drainage basin of the Amazon was split along the middle of the continent by the Purus Arch . Water on the eastern side flowed toward the Atlantic , while to the west water flowed toward the Pacific across the Amazonas Basin . As the Andes Mountains rose, however, a large basin was created that enclosed a lake; now known as the Solimões Basin . Within the last 5–10 million years, this accumulating water broke through

900-526: Is considerable, and areas cleared of forest are visible to the naked eye from outer space. In the 1970s, construction began on the Trans-Amazonian highway . This highway represented a major threat to the Amazon rainforest. The highway still has not been completed, limiting the environmental damage. Between 1991 and 2000, the total area of forest lost in the Amazon rose from 415,000 to 587,000 km (160,000 to 227,000 sq mi), with most of

975-426: Is estimated at 356 ± 47 tonnes per hectare. To date, an estimated 438,000 species of plants of economic and social interest have been registered in the region with many more remaining to be discovered or catalogued. The total number of tree species in the region is estimated at 16,000. The green leaf area of plants and trees in the rainforest varies by about 25% as a result of seasonal changes. Leaves expand during

1050-500: Is expressed through a prefixation. The syntax of Ayoreo is characterized by the presence of para - hypotactical structures. Amazon Rainforest The Amazon rainforest , also called Amazon jungle or Amazonia , is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America . This basin encompasses 7,000,000 km (2,700,000 sq mi), of which 6,000,000 km (2,300,000 sq mi) are covered by

1125-465: Is spoken by the Ayoreo people , an indigenous ethnic group traditionally living on a combined hunter-gatherer and farming lifestyle. Ayoreo is classified as a Zamucoan language, along with Chamacoco . Extinct Guarañoca may have been a dialect. Ayoreo is spoken in both Paraguay and Bolivia , with 3,100 speakers total, 1,700 of whom live in Paraguay and 1,400 in Bolivia. Within Paraguay, Ayoreo

1200-702: Is spoken in the Chaco Department and the northern parts of the Alto Paraguay Department . In Bolivia, it is spoken in the Cordillera Province , in the Santa Cruz Department . Bertinetto (2009) reports that Ayoreo has the 5 vowels /a, e, i, o, u/ , which appear both as oral and nasal. / j / can also be heard as [ dʒ ] . The prototypical constituent order is subject-verb-object , as seen in

1275-571: Is the conversion of forested areas to non-forested areas. The main sources of deforestation in the Amazon are human settlement and the development of the land. In 2022, about 20% of the Amazon rainforest has already been deforested and a further 6% was "highly degraded". Research suggests that upon reaching about 20–25% (hence 0–5% more), the tipping point to flip it into a non-forest ecosystem – degraded savannah – (in eastern, southern and central Amazonia) will be reached. This process of savanisation would take decades to take full effect. Prior to

1350-641: Is the maximum that can be sustained in the rainforest through hunting, with agriculture needed to host a larger population. However, recent anthropological findings have suggested that the region was actually densely populated. The Upano Valley sites in present-day eastern Ecuador predate all known complex Amazonian societies. Some 5 million people may have lived in the Amazon region in AD 1500, divided between dense coastal settlements, such as that at Marajó , and inland dwellers. Based on projections of food production, one estimate suggests over 8 million people living in

1425-460: The Amazons of Greek mythology , described by Herodotus and Diodorus . Based on archaeological evidence from an excavation at Caverna da Pedra Pintada , human inhabitants first settled in the Amazon region at least 11,200 years ago. Subsequent development led to late-prehistoric settlements along the periphery of the forest by AD 1250, which induced alterations in the forest cover . For

1500-532: The Eocene era (from 56 million years to 33.9 million years ago). It appeared following a global reduction of tropical temperatures when the Atlantic Ocean had widened sufficiently to provide a warm, moist climate to the Amazon basin. The rainforest has been in existence for at least 55 million years, and most of the region remained free of savanna -type biomes at least until the current ice age when

1575-624: The Natural History Museum in London, was suspended when concerns were raised that Ayoreo people might be encountered and disturbed. The Ayoreo are divided into seven clans, with each clan having a particular last name associated with it. The Ayoreo have a deep connection to Eami , their collective territory. They are nomadic hunter-gatherers, but in the rainy season they plant small amounts of crops, including corn, beans, and squash. They hunt anteaters, pigs, tortoises, and monkeys in

1650-581: The Villas-Bôas brothers ' campaign, which faced strong opposition from the government and the ranchers of Mato Grosso and led to the establishment of the first Brazilian National Park for indigenous people along the Xingu River in 1961. In 1961, British explorer Richard Mason was killed by an uncontacted Amazon tribe known as the Panará . The Matsés made their first permanent contact with

1725-537: The rainforest . This region includes territory belonging to nine nations and 3,344 indigenous territories . The majority of the forest, 60%, is in Brazil , followed by Peru with 13%, Colombia with 10%, and with minor amounts in Bolivia , Ecuador , French Guiana , Guyana , Suriname , and Venezuela . Four nations have " Amazonas " as the name of one of their first-level administrative regions , and France uses

1800-434: The release of the carbon contained within the vegetation, which could accelerate global warming . Amazonian evergreen forests account for about 10% of the world's terrestrial primary productivity and 10% of the carbon stores in ecosystems – of the order of 1.1 × 10 metric tonnes of carbon. Amazonian forests are estimated to have accumulated 0.62 ± 0.37 tons of carbon per hectare per year between 1975 and 1996. In 2021 it

1875-469: The 2000s. Oil companies have to set up their operations by opening new roads through the forests, which often contributes to deforestation in the region. 9.4% of the territory of the Amazon is affected by oil fields. Mining is also a major driver of deforestation. 17% of the area of the Amazon Rainforest is affected by mining. The transition to solar and wind energy, digitalization, raised

1950-461: The Amazon in 1492. By 1900, the native indigenous population had fallen to 1 million and by the early 1980s it was less than 200,000. The first European to travel the length of the Amazon River was Francisco de Orellana in 1542. The BBC's Unnatural Histories presents evidence that Orellana, rather than exaggerating his claims as previously thought, was correct in his observations that

2025-526: The Amazon rainforest are probably the result of centuries of human management, rather than naturally occurring as has previously been supposed. In the region of the Xingu tribe, remains of some of these large settlements in the middle of the Amazon forest were found in 2003 by Michael Heckenberger and colleagues of the University of Florida . Among those were evidence of roads, bridges and large plazas. In

2100-727: The Amazon rainforest comes from the Bodélé depression in Northern Chad in the Sahara desert. The dust contains phosphorus , important for plant growth. The yearly Sahara dust replaces the equivalent amount of phosphorus washed away yearly in Amazon soil from rains and floods. NASA's CALIPSO satellite has measured the amount of dust transported by wind from the Sahara to the Amazon: an average of 182 million tons of dust are windblown out of

2175-532: The Amazon rainforest could become unsustainable under conditions of severely reduced rainfall and increased temperatures, leading to an almost complete loss of rainforest cover in the basin by 2100., and severe economic, natural capital and ecosystem services impacts of not averting the tipping point. However, simulations of Amazon basin climate change across many different models are not consistent in their estimation of any rainfall response, ranging from weak increases to strong decreases. The result indicates that

2250-460: The Amazon rainforest, rather than being a pristine wilderness , has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta . Terra preta is found over large areas in the Amazon forest; and is now widely accepted as a product of indigenous soil management . The development of this fertile soil allowed agriculture and silviculture in the previously hostile environment; meaning that large portions of

2325-578: The Amazon region. In August 2019 there were a record number of fires. Deforestation in the Brazilian Amazon rose more than 88% in June 2019 compared with the same month in 2018. The increased area of fire-impacted forest coincided with a relaxation of environmental regulations from the Brazilian government. Notably, before those regulations were put in place in 2008 the fire-impacted area

Indigenous peoples make up 9% of the total population, and 60 of the groups remain largely isolated. Large scale deforestation is occurring in the forest, creating different harmful effects. Economic losses due to deforestation in Brazil could be approximately 7 times higher in comparison to

Several tribes of the Jivaroan group, including the Shuar , practised headhunting for trophies and headshrinking . The accounts of missionaries to the area in the borderlands between Brazil and Venezuela have recounted constant infighting in the Yanomami tribes. More than a third of the Yanomamo males, on average, died from warfare. The Munduruku were

Ayoreo children were stolen during this time, including a twelve-year-old named Iquebi who was taken to be put in an exhibit. In the 1940s the Santa Cruz-Corumba railroad was built in Ayoreo territory, making the territory and people easier to access. Christian missionaries made contact with

2625-471: The Ayoreo in the late 1940s, first with the northern groups in Bolivia and then with the southern groups in Paraguay. The missionary groups were Catholic , Mennonite , and Evangelical , including the New Tribes Mission . Against the teachings of Jesus Christ , missionaries used force and manipulation to remove the Ayoreo from their land to various mission stations in the late 1950s. Afterwards,

2700-1031: The Ayoreo-Totobiegosode. They are the only extant uncontacted tribes in South America not living in the Amazon . Three groups are in the Northern region of the Gran Chaco on the border of Bolivia and Paraguay in the areas of Médanos del Chaco National Park , Defensores del Chaco National Park , and Chovoreca . The other three to four groups are in the Southern region of the territory. UNAP (Unión Nativa Ayoreo del Paraguay) lists six threats to Ayoreo living in voluntary isolation: cattle farming and deforestation, sale and allocation of Ayoreo territory, searches for oil, missionaries seeking contact, illegal collection of territory resources, and violation of territory by various groups. Cattle farming and

There are few jobs, so people often work as day laborers in construction or gardening. Youth have few opportunities, so there

2850-665: The Payipie Ichadie Totobiegosode Organization). There is also an organization that specifically represents Ayoreo communities around the Paraguay River, Consejo de Líderes de Alto Paraguay. Various non-governmental organizations (NGOs) support Ayoreo organizations, such as APCOB, GAT (Gente, Ambiente, Territorio), which works with OPIT. UNAP and the NGO Iniciativa Amotocodie (IA) monitor Ayoreo territory to confirm

So despite the popular perception, there has been no economical advantage for Brazil from logging rainforest zones and converting these to pastoral fields. The needs of soy farmers have been used to justify many of the controversial transportation projects that are currently developing in the Amazon. The first two highways successfully opened up

3225-471: The climate was drier and savanna more widespread. Following the Cretaceous–Paleogene extinction event , the extinction of the dinosaurs and the wetter climate may have allowed the tropical rainforest to spread out across the continent. From 66 to 34 Mya , the rainforest extended as far south as 45° . Climate fluctuations during the last 34 million years have allowed savanna regions to expand into

This led to deforestation, different environmental and social problems. Hydropower also creates significant problems in the Amazon. Such activities are defined by the World Rainforest Movement as " Green extractivism ". The European Union–Mercosur free trade agreement , which would form one of

The amount of species per hectare in the Amazon rainforest can be presented in the next table: The rainforest contains several species that can pose

3525-591: The early 1960s, access to the forest's interior was highly restricted, and the forest remained basically intact. Farms established during the 1960s were based on crop cultivation and the slash and burn method. However, the colonists were unable to manage their fields and the crops because of the loss of soil fertility and weed invasion. The soils in the Amazon are productive for just a short period of time, so farmers are constantly moving to new areas and clearing more land. These farming practices led to deforestation and caused extensive environmental damage. Deforestation

Chiefs, called asutes , are exclusively men chosen for killing the most people or animals. Music is an integral part of Mayoress culture, and songs are passed down over time. The Ayoreo tend to be monogamous. There are records of infanticide where babies are buried alive for various reasons, such as when

3750-511: The forest to sedentarize and convert. Protestant missionaries led these ventures from 1979-1986 to find the Totobiegosode group, which led to international protest. In December 1986, a group of Ayoreo people in contact went into the forest to find uncontacted Ayoreo to evangelize, but the incident turned violent, resulting in five deaths. The Totobiegosode also attacked a group of workers in their territory in June 1998. In 2010, an expedition in search of new species of plants and insects, organized by

3900-411: The land was purchased for cattle farming. The missionaries also brought diseases such as measles to the Ayoreo, leading to the death of many people. While at the mission stations, the Ayoreo had to adopt a sedentary lifestyle and give up their culture, including their religion, appearance, music, and diet. The missionaries sometimes convinced the Ayoreo living at the missions to find uncontacted Ayoreo in

The Ayoreo were first contacted when the Jesuits started the San Ignacio Zamuco mission in the 1720s to convert the people to Catholicism. The mission was abandoned in the 1740s, and the Ayoreo were left alone until the 1900s. The Chaco War (1932-1935) between Bolivia and Paraguay brought 100,000 troops to their territory, as well as new diseases. Both countries viewed

The Amazon represents over half of the total area of remaining rainforests on Earth , and comprises the largest and most biodiverse tract of tropical rainforest in the world, with an estimated 390 billion individual trees in about 16,000 species. More than 30 million people of 350 different ethnic groups live in

Nine countries share the Amazon basin—most of the rainforest, 58.4%, is contained within the borders of Brazil. The other eight countries are Peru with 12.8%, Bolivia with 7.7%, Colombia with 7.1%, Venezuela with 6.1%, Guyana with 3.1%, Suriname with 2.5%, French Guiana with 1.4% and Ecuador with 1%. The rainforest likely formed during

By trying to evangelize the Ayoreo, missionaries risk spreading diseases and violate laws protecting indigenous peoples from contact. The collection of resources takes necessities from the people living in the territory and risks contact. The violation of territories occurs when groups enter Ayoreo land without permission, creating

In present day, the Amazon receives approximately 9 feet of rainfall annually. There is a debate, however, over how extensive this reduction was. Some scientists argue that the rainforest was reduced to small, isolated refugia separated by open forest and grassland; other scientists argue that

The biodiversity in the Amazon is becoming increasingly threatened, primarily by habitat loss from deforestation as well as increased frequency of fires. Over 90% of Amazonian plant and vertebrate species (13,000–14,000 in total) may have been impacted to some degree by fires. Deforestation

The mean annual deforestation rate from 2000 to 2005 (22,392 km or 8,646 sq mi per year) was 18% higher than in the previous five years (19,018 km or 7,343 sq mi per year). Although deforestation declined significantly in the Brazilian Amazon between 2004 and 2014, there has been an increase to the present day. Brazil's President, Jair Bolsonaro, has supported

4650-676: The rainforest could be threatened through the 21st century by climate change in addition to deforestation. In 1989, environmentalist C.M. Peters and two colleagues stated there is economic as well as biological incentive to protecting the rainforest. One hectare in the Peruvian Amazon has been calculated to have a value of $ 6820 if intact forest is sustainably harvested for fruits, latex, and timber; $ 1000 if clear-cut for commercial timber (not sustainably harvested); or $ 148 if used as cattle pasture. As indigenous territories continue to be destroyed by deforestation and ecocide (such as in

4725-409: The rainforest remained largely intact but extended less far to the north, south, and east than is seen today. This debate has proved difficult to resolve because the practical limitations of working in the rainforest mean that data sampling is biased away from the center of the Amazon basin, and both explanations are reasonably well supported by the available data. More than 56% of the dust fertilizing

Scientists have described between 96,660 and 128,843 invertebrate species in Brazil alone. The biodiversity of plant species is the highest on Earth with one 2001 study finding a quarter square kilometer (62 acres) of Ecuadorian rainforest supports more than 1,100 tree species. A study in 1999 found one square kilometer (247 acres) of Amazon rainforest can contain about 90,790 tonnes of living plants. The average plant biomass

4875-497: The relaxation of regulations placed on agricultural land. He has used his time in office to allow for more deforestation and more exploitation of the Amazon's rich natural resources. Deforestation reached a 15 year high in 2021. Since the discovery of fossil fuel reservoirs in the Amazon rainforest, oil drilling activity has steadily increased, peaking in the Western Amazon in the 1970s and ushering another drilling boom in

4950-517: The settlements tend to be slums with poor conditions, such as houses made of mud and cane. Discrimination is especially prevalent in the healthcare system, where Ayoreo people have to wait for extended periods of time to be seen, which can lead them to avoid seeking treatment. In 2010, a group of Ayoreo-Atetadiegosode people in contact decided to return to their ancestral land to live a traditional lifestyle, and other groups may follow. There are about 100 uncontacted Ayoreo in 6 to 7 groups today, including

5025-497: The small patches of forest remaining around cattle pastures. Lucas Bessire recorded one story of the time before contact from a member of the Areguede’urasade that reflects the traumatic experience the people suffered: “We saw tracks. Cojñone [the Ayoreo term for a white people], Strangers. Where? It was hot. We ran far. Faaar. Swollen tongues. We cried. Crawling low. A water tank. It was full. One Cojnoi. Fat. A red shirt. Blood in

5100-448: The subsequent deforestation is often illegal, destroys territory and resources such as water, and increases the chance of unwanted contact. Various laws give the Ayoreo the right to ownership over the land they live on, which prohibits people from entering or selling the land, yet about eight million hectares is still redistributed. Owners often claim no one lives on their land despite evidence proving otherwise. Oil testing on Ayoreo disturbs

It expanded again during the Middle Miocene , then retracted to a mostly inland formation at the last glacial maximum . However, the rainforest still managed to thrive during these glacial periods , allowing for the survival and evolution of a broad diversity of species. During the mid-Eocene , it

When the two tribes became one, the Areguede’urasade were forced to give up their culture, convert to Christianity, and perform servile tasks for the initial Totobiegosode group. Significant health issues were seen among members as
