Maniçoba is an Amazonian dish from Brazil made with pieces of meat, sausage, manioc, and culantro leaves. Amazonian cuisine includes many freshwater fish such as peixe nobre (noble fish), the pirarucu (the world's largest freshwater fish), [citation needed] and tambaqui.
The Amazon rainforest, [a] 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 (2,700,000 sq mi), [ 2 ] of which 6,000,000 km 2 (2,300,000 sq mi) are covered by the rainforest . [ 3 ]
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Manatees make seasonal movements synchronized with the flood regime of the Amazon Basin. [7] They are found in flooded forests and meadows during the flood season, when food is abundant. [7] The Amazonian manatee has the smallest degree of rostral deflection (25° to 41°) among sirenians, an adaptation to feed closer to the water surface. [18]
Scientists can predict tipping points for ecosystem collapse. The most frequently used model for predicting food web collapse is called R50, which is a reliable measurement model for food web robustness. [29] However, there are others: i.e. marine ecosystem assessments can use RAM Legacy Stock Assessment Database.
Amazonian soils are generally nutrient-poor in central and northwestern Amazon and are moderately rich in southwestern Amazon. Anthrosols are soils whose fertility has been enhanced by humans. Pre-Columbian settlements appear to have been active over the centuries in enhancing certain soils, which are now known as terra preta (dark earth in ...
Vegetation types are dense rainforest (77%), open rainforest (14%), transition from rainforest to campinarana (7%) and campinarana (2%). Botanists have catalogued about 400 plant species, several of which are restricted to certain environments such as the uplands and the flooded areas. 263 species of fish have been recorded, some new to science.
The dense tropical Amazon rainforest is the largest tropical rainforest in the world. [2] It covers between 5,500,000 and 6,200,000 square kilometres (2,100,000 and 2,400,000 sq mi) of the 6,700,000 to 6,900,000 square kilometres (2,600,000 to 2,700,000 sq mi) Amazon biome. The somewhat vague numbers are because the rainforest merges into ...
