Gurupa Várzea
The Gurupa várzea (NT0126) is an ecoregion of seasonally and tidally flooded várzea forest along the Amazon River in the Amazon biome. Location The Gurupa várzea ecoregion is named after the Ilha Grande de Gurupá, an alluvial island in the mouth of the Amazon. The Várzea forest, várzea extends along the lower Amazon River from the mouth of the Tapajós down to the mouth of the Xingu River. It has an area of . The Tapajós–Xingu moist forests lie to the south and the Uatuma–Trombetas moist forests to the north. The Monte Alegre várzea is upstream and the Marajó várzea is downstream along the Amazon. Physical In this region the whitewater Amazon is fed by the blackwater river, blackwater Xingú River, Xingú, Jari River, Jari, and Tapajós River, Tapajós rivers. Elevations are no more than . The Gurupa várzea contains floodplains along the river that are affected by daily Atlantic Ocean tidal fluctuations and seasonal flooding. At the height of the rainy season when ...

Blackwater River
A blackwater river is a type of River#Classification, river with a slow-moving channel flowing through forested swamps or wetlands. Most major blackwater rivers are in the Amazon Basin and the Southern United States. The term is used in fluvial studies, geology, geography, ecology, and biology. Not all dark rivers are blackwater in that technical sense. Some rivers in temperate regions, which drain or flow through areas of dark black loam, are simply black due to the color of the soil; these rivers are ''black mud rivers''. There are also black mud Estuary, estuaries. Blackwater rivers are lower in nutrients than Whitewater river (river type), whitewater rivers and have Ionic strength, ionic concentrations higher than rainwater. The unique conditions lead to flora and fauna that differ from both whitewater and Clearwater river (river type), clearwater rivers. The classification of Amazonian rivers into black, clear, and whitewater was first proposed by Alfred Russel Wallace in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Echinochloa Spectabilis
''Echinochloa'' is a very widespread genus of plants in the grass family and tribe Paniceae. Some of the species are known by the common names barnyard grass or cockspur grass. Some of the species within this genus are millets that are grown as cereal or fodder crops. The most notable of these are Japanese millet (''E. esculenta'') in East Asia, Indian barnyard millet (''E. frumentacea'') in South Asia, and burgu millet (''E. stagnina'') in West Africa. Collectively, the members of this genus are called barnyard grasses (though this may also refer to '' E. crus-galli'' specifically), and are also known as barnyard millets or billion-dollar grasses. When not grown on purpose, these grasses may become a nuisance to farmers. In particular, common barnyard grass (''E. crus-galli'') is notorious as a weed. It is not easily suppressed with living mulches such as velvet bean (''Mucuna pruriens'' var. ''utilis''). Early barnyard grass (''E. oryzoides'') is a well-known example o ...

Echinochloa Polystachya
''Echinochloa polystachya'', the German grass, is a species of grass (family Poaceae), native to the New World Tropics and Subtropics, from Texas and Florida down to Argentina. It is an aquatic or semi-aquatic perennial that can grow in water as deep as . It is a useful fodder for water buffaloes, and to a lesser extent, cattle. In the Amazon floodplain it can reach productivity levels of in dry mass, one of the highest levels ever measured in natural vegetation and belongs to the C4 plants . Given that it occupies about of territory during the rainy season, it contributes on the order of 1% of the primary productivity of the planet.

Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. 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'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...

Tropical And Subtropical Moist Broadleaf Forests
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature (WWF). Description TSMF is generally found in large, discontinuous patches centered on the equatorial belt and between the Tropic of Cancer and Tropic of Capricorn. TSMF are characterized by low variability in annual temperature and high levels of rainfall of more than annually. Forest composition is dominated by evergreen and semi-deciduous tree species. These forests are home to more species than any other terrestrial ecosystem on Earth: Half of the world's species may live in these forests, where a square kilometer may be home to more than 1,000 tree species. These forests are found around the world, particularly in the Indo-Malayan Archipelago, the Amazon Basin, and the African Congo Basin. The perpetually warm, wet climate makes these environments more productive than any ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andes
The Andes ( ), Andes Mountains or Andean Mountain Range (; ) are the List of longest mountain chains on Earth, longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long and wide (widest between 18th parallel south, 18°S and 20th parallel south, 20°S latitude) and has an average height of about . The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela. Along their length, the Andes are split into several ranges, separated by intermediate depression (geology), depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, Mérida, Mérida, El Alto, and La Paz. The Altiplano, Altiplano Plateau is the world's second highest after the Tibetan Plateau. These ranges are in turn grouped into three majo ...
