Study: Amazon deforestation brings loss of microbial communities

An international team of microbiologists led by Klaus Nüsslein of the University of Massachusetts Amherst has found that a troubling net loss in diversity among the microbial organisms responsible for a functioning ecosystem ...

Land in a cyclone's wake becomes more vulnerable to forest fires

The strong winds and torrential rains that accompany a cyclone do tremendous damage to ecosystems, and this damage can make them more prone to future wildfires. As intense cyclones are projected to become more frequent worldwide, ...

High-flying morpho butterflies evolved into efficient gliders

Some morpho butterflies live and fly high in the canopy of the Amazonian rainforest, and have evolved into highly-efficient gliding flyers. These results revealed by Wageningen University & Research and published in Science ...

Domesticated chickens have smaller brains

Researchers from Linköping University suggest a process by which the timid junglefowl from the rain forest could have become today's domesticated chicken. When the scientists selectively bred the junglefowl with least fear ...

How does the Amazon rain forest cope with drought?

The Amazon rain forest isn't necessarily a place that many would associate with a drought, yet prolonged dry spells are projected to become more prevalent and severe because of climate change. The question at hand is how ...

Rainforest

Rainforests are forests characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1750–2000 mm (68-78 inches). The monsoon trough, alternately known as the intertropical convergence zone, plays a significant role in creating Earth's tropical rain forests.

From 40 to 75% of all species on Earth are indigenous to the rainforests. It has been estimated that many millions of species of plants, insects, and microorganisms are still undiscovered. Tropical rainforests have been called the "jewels of the Earth", and the "world's largest pharmacy", because of the large number of natural medicines discovered there. Rainforests are also responsible for 28% of the worlds oxygen turn over, often misunderstood as oxygen production, processing it through photosynthesis from carbon dioxide and through breathing to carbon dioxide.

The undergrowth in a rainforest is restricted in many areas by the lack of sunlight at ground level. This makes it possible to walk through the forest. If the leaf canopy is destroyed or thinned, the ground beneath is soon colonized by a dense, tangled growth of vines, shrubs, and small trees called a jungle. There are two types of rainforest, tropical rainforest and temperate rainforest.
