La selva amazónica se desarrolla alrededor del río Amazonas y de su cuenca fluvial. Las altas temperaturas favorecen el desarrollo de una vegetación tupida y exuberante, siempre verde. El título de el pulmón del planeta que ostenta la Amazonia no es metafórico ya que mantiene un equilibrio climático: los ingresos y salidas de CO2 y de O2 están balanceados. Los científicos ambientalistas concuerdan en que la pérdida de la biodiversidad es resultado de la destrucción de la selva, y que se evidencia con la aparición en el área del Caquetá a un sistema anterior del bosque selvático en el cual se utilizaron suelos de forma permanente tierras pretas gracias a su progresivo abono y por lo que así evitó las migraciones.
Wet tropical forests are the most species-rich biome, and tropical forests in the Americas are consistently more species rich than the wet forests in Africa and Asia.[16] As the largest tract of tropical rainforest in the Americas, the Amazonian rainforests have unparalleled biodiversity. One in ten known species in the world live in the Amazon Rainforest.[17] This constitutes the largest collection of living plants and animal species in the world.
The region is home to about 2.5 million insect species,[18] tens of thousands of plants, and some 2,000 birds and mammals. To date, at least 40,000 plant species, 3,000 fish, 1,294 birds, 427 mammals, 428 amphibians, and 378 reptiles have been scientifically classified in the region.[19] One in five of all the birds in the world live in the rainforests of the Amazon. Scientists have described between 96,660 and 128,843 invertebrate species in Brazil alone.[20]
The diversity of plant species is the highest on Earth with some experts estimating that one square kilometer may contain over 75,000 types of trees and 150,000 species of higher plants. One square kilometer of Amazon rainforest can contain about 90,790 tonnes of living plants. The average plant biomass is estimated at 356 ± 47 tonnes ha−1.[21] To date, an estimated 438,000 species of plants of economic and social interest have been registered in the region with many more remaining to be discovered or catalogued.[22]
The green leaf area of plants and trees in the rainforest varies by about 25% as a result of seasonal changes. Leaves expand during the dry season when sunlight is at a maximum, then undergo abscission in the cloudy wet season. These changes provide a balance of carbon between photosynthesis and respiration.[23]
The rainforest contains several species that can pose a hazard. Among the largest predatory creatures are the Black Caiman, Jaguar and Anaconda. In the river, electric eels can produce an electric shock that can stun or kill, while Piranha are known to bite and injure humans.[24] Various species of poison dart frogs secrete lipophilic alkaloid toxins through their flesh. There are also numerous parasites and disease vectors. Vampire bats dwell in the rainforest and can spread the rabies virus.[25] Malaria, yellow fever and Dengue fever can also be contracted in the Amazon region.verde,green
