Native American Use Of Fire In Ecosystems
Prior to the European colonization of the Americas, indigenous peoples used fire to modify the landscape. This influence over the fire regime was part of the environmental cycles and maintenance of wildlife habitats that sustained the cultures and economies of the Indigenous peoples of the Americas. What was initially perceived by colonists as "untouched, pristine" wilderness in North America was the cumulative result of the indigenous use of fire, creating a mosaic of grasslands and forests across North America, sustained and managed by the peoples indigenous to the landscape. Radical disruption of indigenous burning practices occurred with European colonization and the forced relocation of those who had historically maintained the landscape. Some colonists understood the traditional use and benefits of low-intensity broadcast burns ("Indian-type" fires), but others feared and suppressed them. By the 1880s, the impacts of colonization had devastated indigenous populations, and f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Colonization Of The Americas
During the Age of Discovery, a large scale colonization of the Americas, involving a number of European countries, took place primarily between the late 15th century and the early 19th century. The Norse explored and colonized areas of Europe and the North Atlantic, colonizing Greenland and creating a short-term settlement near the northern tip of Newfoundland circa 1000 AD. However, due to its long duration and importance, the later colonization by the European colonial powers of the Americas, after Christopher Columbus’s voyages, is more well-known. During this time, the European colonial empires of Spain, Portugal, Great Britain, France, Russia, the Netherlands, Denmark, and Sweden began to explore and claim the Americas, its natural resources, and human capital, leading to the displacement, disestablishment, enslavement, and even genocide of the Indigenous peoples in the Americas, and the establishment of several settler colonial states. The rapid rate at which so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Henry Hudson
William Henry Hudson (4 August 1841 – 18 August 1922), known in Argentina as Guillermo Enrique Hudson, was an English Argentines, Anglo-Argentine author, natural history, naturalist and ornithology, ornithologist. Born in the Argentine pampas where he roamed free in his youth, he observed bird life and collected specimens for the Smithsonian Institution. The Patagonian birds ''Hudson's black tyrant, Knipolegus hudsoni'' and ''Hudson's canastero, Asthenes hudsoni'' are named after him. He would later write about life in Patagonia that drew special admiration for his style. His most popular work ''Green Mansions'' (1904), a romance set in the Venezuelan forest inspired a Cinema of the United States, Hollywood movie and several other works. Life Hudson was the fourth child of Daniel Hudson (1804–1868) and his wife Caroline Augusta (1804–1859), United States settlers of English and Irish origin. His paternal grandfather was from Clyst Hydon in Devon. He was born and lived his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cree
The Cree, or nehinaw (, ), are a Indigenous peoples of the Americas, North American Indigenous people, numbering more than 350,000 in Canada, where they form one of the country's largest First Nations in Canada, First Nations. They live primarily to the north and west of Lake Superior in the Provinces and territories of Canada, provinces of Alberta, Labrador, Manitoba, the Northwest Territories, Ontario, and Saskatchewan. Another roughly 27,000 live in Quebec. In the United States, the Cree, historically, lived from Lake Superior westward. Today, they live mostly in Montana, where they share Rocky Boy's Indian Reservation with Ojibwe (Chippewa) people. A documented westward migration, over time, has been strongly associated with their roles as traders and hunters in the North American fur trade. Sub-groups and geography The Cree are generally divided into eight groups based on dialect and region. These divisions do not necessarily represent ethnic subdivisions within th ...

Blackfeet Nation
The Blackfeet Nation (, ), officially named the Blackfeet Tribe of the Blackfeet Indian Reservation of Montana, is a federally recognized tribe of Siksikaitsitapi people with an Indian reservation in Montana. Tribal members primarily belong to the Piegan Blackfeet (Ampskapi Piikani) band of the larger Blackfoot Confederacy that spans Canada and the United States. The Blackfeet Indian Reservation is located east of Glacier National Park and borders the Canadian province of Alberta. Cut Bank Creek and Birch Creek form part of its eastern and southern borders. The reservation contains 3,000 square miles (7,800 km2), twice the size of the national park and larger than the state of Delaware. It is located in parts of Glacier and Pondera counties. History The Blackfeet claim to have lived on the Northern Great Plains for thousands of years. Through raids in the Southern Plains and trade with the Cree, they eventually acquired firearms and horses. They were a powerful fo ...

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributary, tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela, as well as the territory of French Guiana. Most of the basin is covered by the Amazon rainforest, also known as Amazon rainforest, Amazonia. With a area of dense tropical forest, it is the largest rainforest in the world. Geography The Amazon River begins in the Andes, Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurímac River, Apurimac River in Peru. The highest point in the Drainage divide, watershed of the Amazon is the second biggest peak of Yerupajá at .

Terra Preta
''Terra preta'' (, literally "black soil" in Portuguese language, Portuguese), also known as Amazonian dark earth or Indian black earth, is a type of very dark, fertile human impact on the environment, anthropogenic soil (anthrosol) found in the Amazon Basin. In Portuguese its full name is or ' ("black soil of the Indigenous peoples of the Americas, Indian", "Indians' black earth"). ''Terra mulata'' ("mulatto earth") is lighter or brownish in color. ''Terra preta'' owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bones, broken pottery, compost and manure to the low fertility Amazonian soil. A product of indigenous Indigenous peoples of the Amazon, Amazonian soil management and slash-and-char agriculture, the charcoal is stable and remains in the soil for thousands of years, binding and retaining minerals and nutrients. ''Terra preta'' is characterized by the presence of low-temperature charcoal residues in high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoel Cláudio da ...

Grassland
A grassland is an area where the vegetation is dominance (ecology), dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes such as clover, and other Herbaceous plant, herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures."

Wildland Fire In Ecosystems 15-1-2
Wilderness or wildlands (usually in the plural) are Earth's natural environments that have not been significantly modified by human activity, or any nonurbanized land not under extensive agricultural cultivation. The term has traditionally referred to terrestrial environments, though growing attention is being placed on marine wilderness. Recent maps of wilderness suggest it covers roughly one-quarter of Earth's terrestrial surface, but is being rapidly degraded by human activity. Even less wilderness remains in the ocean, with only 13.2% free from intense human activity. Some governments establish protection for wilderness areas by law to not only preserve what already exists, but also to promote and advance a natural expression and development. These can be set up in preserves, conservation preserves, national forests, national parks and even in urban areas along rivers, gulches or otherwise undeveloped areas. Often these areas are considered important for the surviva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genocide Of Native Americans
The destruction of Native American peoples, cultures, and languages has been characterized as genocide. Debates are ongoing as to whether the entire process or only specific periods or events meet the definitions of genocide. Many of these definitions focus on intent, while others focus on outcomes. Raphael Lemkin, who coined the term "genocide", considered the displacement of Native Americans by European settlers as a historical example of genocide. Others, like historian Gary Anderson, contend that genocide does not accurately characterize any aspect of American history, suggesting instead that ethnic cleansing is a more appropriate term. Historians have long debated the pre-European population of the Americas. In 2023, historian Ned Blackhawk suggested that Northern America's population (Including modern-day Canada and the United States) had halved from 1492 to 1776 from about 8 million people (all Native American in 1492) to under 4 million (predominantly white in 1776). ...

Native American Disease And Epidemics
The history of Native American disease and epidemics is fundamentally composed of two elements: indigenous diseases and those brought by settlers to the Americas from the Old World (Africa, Asia, and Europe). Although a variety of infectious diseases existed in the Americas in pre-Columbian times, the limited size of the populations, smaller number of domesticated animals with zoonotic diseases, and limited interactions between those populations (as compared to areas of Eurasia and Africa) hampered the transmission of communicable diseases. One notable infectious disease that may be of American origin is syphilis. Aside from that, most of the major infectious diseases known today originated in the Old World. The American era of limited infectious disease ended with the arrival of Europeans in the Americas and the Columbian exchange of microorganisms, including those that cause human diseases. European infections and epidemics had major effects on Native American life in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Population History Of Indigenous Peoples Of The Americas
Population figures for the Indigenous peoples of the Americas before European colonization have been difficult to establish. Estimates have varied widely from as low as 8 million to as many as 100 million, though by the end of the 20th Century, many scholars gravitated toward an estimate of around 50 million people. The monarchs of the nascent Spanish Empire decided to fund Christopher Columbus' voyage in 1492, leading to the establishment of colonies and marking the beginning of the migration of millions of Europeans and Africans to the Americas. While the population of European settlers, primarily from Spain, Portugal, France, England, and the Netherlands, along with African slaves, grew steadily, the Indigenous population plummeted. There are numerous reasons for the population decline, including exposure to Eurasian diseases such as influenza, pneumonic plagues, and smallpox; direct violence by settlers and their allies through war and forced removal; and the general ...
