Rio Curiaú Environmental Protection Area
The Rio Curiaú Environmental Protection Area ( pt, Área de Proteção Ambiental do Rio Curiaú) is an environmental protection area in the state of Amapá, Brazil. It attempts to protect the environment of a region of forest and flooded fields close to the state capital, Macapá, and also to preserve the values and culture of the traditional population, which is of African descent. It is threatened by urban expansion. Location The Rio Curiaú Environmental Protection Area (APA) is in the municipality of Macapá, Amapá, about from the city center, and has an area of . The Curiaú River, which gives its name to the APA, rises in the APA and flows southeast into the Amazon. The EAP-070 highway from Macapá runs through the APA from south to north. The APA is bounded to the east by the Amazon River, to the north by the Pescada stream and the road linking the EAP-070 highway to BR-210, to the west by the Amapá railroad, and to the south by an E-W line that divides it from the ...

Macapá
Macapá () is a city in Brazil with a population of 512,902 (2020 estimation). It is the capital of Amapá state in the country's North Region. It is located on the northern channel of the Amazon River near its mouth on the Atlantic Ocean. The city is on a small plateau on the Amazon in the southeast of the state of Amapá. The only access by road from outside the province is from the overseas French department of French Guiana, although there are regular ferries to Belem, Brazil. Macapá is linked by road with some other cities in Amapá. The equator runs through the middle of the city, leading residents to refer to Macapá as "''The capital of the middle of the world.''" It covers and is located northwest of the large inland island of Marajó and south of the border with French Guiana. History Macapá is a corruption of the Tupi word ''macapaba'', or "''place of many bacabas''", the fruit of the local palm tree. The Spaniard Francisco de Orellana claimed the region in 1544 ...

Cerrado
The ''Cerrado'' (, ) is a vast ecoregion of tropical savanna in eastern Brazil, particularly in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins, Minas Gerais, and the Federal District. The core areas of the Cerrado biome are the Brazilian highlands – the ''Planalto''. The main habitat types of the Cerrado consist of forest savanna, wooded savanna, park savanna and gramineous-woody savanna. The ''Cerrado'' also includes savanna wetlands and gallery forests. The second largest of Brazil's major habitat types, after the Amazonian rainforest, the Cerrado accounts for a full 21 percent of the country's land area (extending marginally into Paraguay and Bolivia). The first detailed European account of the Brazilian cerrados was provided by Danish botanist Eugenius Warming (1892) in the book ''Lagoa Santa'', : The above is the original. There are other, later French and Portuguese translations not listed here. in which he describes the main features of the c ...

Protected Areas Of Amapá
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage serving ...

Environmental Protection Areas Of Brazil
A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment. The term ''environment'' can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency. Life-environment interaction All life that has survived must have adapted to the conditions of its environment. Temperature, light, humidity, soil nutrients, etc., all influence the species within an environment. However, life in turn modifies, in various forms, its conditions. S ...

Várzea Forest
A várzea forest is a seasonal floodplain forest inundated by whitewater rivers that occurs in the Amazon biome. Until the late 1970s, the definition was less clear and várzea was often used for all periodically flooded Amazonian forests. Although sometimes described as consisting only of forest, várzea also contains more open, seasonally flooded habitats such as grasslands, including floating meadows. Description Along the Amazon River and many of its tributaries, high annual rainfall that occurs mostly within a rainy season results in extensive seasonal flooding of areas from stream and river discharge. The result is a rise in water level, with nutrient rich waters. The Iquitos várzea ecoregion covers the margins of the upper Amazon and its tributaries. Further down are the Purus várzea in the middle Amazon, the Monte Alegre várzea and Gurupa várzea on the lower Amazon and the Marajó várzea at the mouth of the Amazon. The Marajó várzea is affected by both freshwate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alluvial
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gleysol
A gleysol is a wetland soil (hydric soil) that, unless drained, is saturated with groundwater for long enough to develop a characteristic colour pattern. The pattern is essentially made up of reddish, brownish, or yellowish colours at surfaces of soil particles and/or in the upper soil horizons mixed with greyish/blueish colours inside the peds and/or deeper in the soil. Gleysols are also known as ''Gleyzems'', ''meadow soils'', ''Aqu''-suborders of Entisols, Inceptisols and Mollisols (USDA soil taxonomy), or as ''groundwater soils'' and ''hydro-morphic soils''. Gleysols occur within a wide range of unconsolidated materials, mainly fluvial, marine and lacustrine sediments of Pleistocene or Holocene age, having basic to acidic mineralogy. They are found in depression areas and low landscape positions with shallow groundwater. Wetness is the main limitation on agriculture of virgin gleysols; these are covered with natural swamp vegetation and lie idle or are used for extensive ...

Oxisol
Oxisols are a soil order in USDA soil taxonomy, best known for their occurrence in tropical rain forest within 25 degrees north and south of the Equator. In the World Reference Base for Soil Resources (WRB), they belong mainly to the ferralsols, but some are plinthosols or nitisols. Some oxisols have been previously classified as laterite soils. Formation The main processes of soil formation of oxisols are weathering, humification and pedoturbation due to animals. These processes produce the characteristic soil profile. They are defined as soils containing ''at all depths'' no more than ten percent weatherable minerals, and low cation exchange capacity. Oxisols are always a red or yellowish color, due to the high concentration of iron(III) and aluminium oxides and hydroxides. They also contain quartz and kaolin, plus small amounts of other clay minerals and organic matter. Etymology The word "oxisol" comes from ''"oxide"'' in reference to the dominance of oxide minerals such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Environmental Protection Area (Brazil)
An environmental protection area ( pt, Área de proteção ambiental: APA) is a type of protected area in Brazil that has some degree of human occupation, but where the primary intent is environmental protection. Human occupation is monitored and controlled. An environmental protection area often contains other types of conservation units, which may be more strictly protected. Definition Environmental protection areas (APAs) are defined as part of the National System of Conservation Units regulated by Law 9985 of 18 July 2000. They are one of the types of sustainable use units, which try to reconcile conservation of nature with sustainable use of some natural resources. Other types of sustainable use unit are significant ecological interest area, national forest, extractive reserve, fauna reserve, sustainable development reserve, and natural heritage particular reserve. As of 1993 APAs were defined as areas where wildlife, genetic diversity and other natural resources were to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amapá Biodiversity Corridor
The Amapá Biodiversity Corridor ( pt, Corredor de Biodiversidade do Amapá) is an ecological corridor in the state of Amapá, Brazil. It provides a degree of integrated management for conservation units and other areas covering over 70% of the state. Organization The project to establish the Amapá Biodiversity Corridor was presented by Antônio Waldez Góes da Silva, governor of Amapá, at the 2003 Durban World Conference of Protected Areas. The proposed corridor would include marshland, tropical forest and open spaces of importance in maintaining global biodiversity. The acts that would lead to conservation measures in the corridor were signed in 2005. The corridor covers more than 70% of the state, and should allow for coordinated management of conservation units and indigenous territories in the state in line with the principles laid out in the Rio Convention on Biodiversity. The corridor and the conservation units it contains will be co-funded by the Amapá Fund. The Ama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
