In the animal kingdom, there is general consensus that Brazil has the highest number of both terrestrial vertebrates and invertebrates of any country in the world. [8] This high diversity of fauna can be explained in part by the sheer size of Brazil and the great variation in ecosystems such as Amazon Rainforest, Atlantic Forest, Cerrado, Pantanal, Pampas and the Caatinga.
The Amazon rainforest is a species-rich biome in which thousands of species live, including animals found nowhere else in the world. To date, there is at least 40,000 different kinds of plants, 427 kinds of mammals, 1,300 kinds of birds, 378 kinds of reptiles, more than 400 kinds of amphibians, and around 3,000 freshwater fish are living in Amazon.
Brazil has the largest mammal diversity in the world, with more than 600 described species and more likely to be discovered. According to the International Union for Conservation of Nature , 66 of these species are endangered, and 40% of the threatened taxa belong to the primate group.
A tropical rainforest typically has a number of layers, each with different plants and animals adapted for life in that particular area. Examples include the emergent, canopy, understory and forest floor layers. [19] [20]
The understory is the next layer where very little sunshine reaches; only about 2 to 15 percent of sunshine reaches the understory. The darkest layer is the forest floor, where most of the larger animals live. [6] With multiple environments, the Amazon rainforest is able to provide a home to thousands of birds with different survival needs. [4]
Brazilian mining operation in the Amazon Rainforest. Brazil's President, Jair Bolsonaro, has supported 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. [80]
Deforestation in Brazil’s Amazon rainforest slowed by nearly half compared to the year before, according to government satellite data released Wednesday. In the past 12 months, the Amazon ...
The structure of a tropical rainforest is stratified into layers, each hosting unique ecosystems. These include the emergent layer with towering trees, the densely populated canopy layer, the understory layer rich in wildlife, and the forest floor, which is sparse due to low light penetration. The soil is characteristically nutrient-poor and ...
