Fire And Drought May Push Amazonian Forests Beyond Tipping Point

Woods Hole Research Center Future simulations of climate in the Amazon suggest a longer dry season leading to more drought and fires. Woods Hole Research Center scientists Michael Coe, Paulo Brando, Marcia Macedo and colleagues have published a...

Nonprofit asks the public to donate 50 cents an acre to meet campaign goal of $50,000 WARRENTON, Va., March 28, 2014 /PRNewswire-USNewswire/ -- Rainforest Trust, a nonprofit conservation organization focused on saving threatened lands and endangered species, has announced a cause campaign that invites the public to save 100,000 acres of Amazon rainforest that is home to jaguars, giant river otters, and other endangered wildlife. To launch its "Amazon Earth Day" campaign, Rainforest...

Amazon Inhales More Carbon Than It Emits
2014-03-18 20:28:30

NASA's Jet Propulsion Laboratory A new NASA-led study seven years in the making has confirmed that natural forests in the Amazon remove more carbon dioxide from the atmosphere than they emit, therefore reducing global warming. This finding resolves a long-standing debate about a key component of the overall carbon balance of the Amazon basin. The Amazon's carbon balance is a matter of life and death: living trees take carbon dioxide out of the air as they grow, and dead trees put the...

redOrbit Staff & Wire Reports - Your Universe Online By studying thousands of canopy tree species in the western Amazon, researchers from the Carnegie Institution for Science’s Department of Global Ecology have uncovered geographically nested patterns of chemical traits they say will help determine how the ecosystem will respond to changes in land use and climate. Writing in the March 3 edition of the Proceedings of the National Academy of Sciences (PNAS), the study authors set...

NASA Study Points To Infrared-Herring As Cause Of Apparent Amazon Green-Up
2014-02-07 10:42:54

Kathryn Hansen, NASA For the past eight years, scientists have been working to make sense of why some satellite data seemed to show the Amazon rainforest "greening-up" during the region's dry season each year from June to October. The green-up indicated productive, thriving vegetation in spite of limited rainfall. Now, a new NASA study published today in the journal Nature shows that the appearance of canopy greening is not caused by a biophysical change in Amazon forests, but instead...

Genes And Calls Reveal Greater Diversity Of Amazon Frog Species
2014-01-15 15:12:22

Pensoft Publishers Amazonian biodiversity has been studied for hundreds of years. Early explorers of Amazonian plants and animals included renowned naturalists of the stature of Alexander von Humboldt and A. R. Wallace. Despite this long history of exploration, new studies are resulting in the discovery of a large number of new species. The key of these discoveries lies in the use of advanced new tools for species detection. The study, published in the open access journal ZooKeys, found...

UT Arlington researchers focusing on the Amazon recently found that widespread conversion from rainforest to pastureland has significant effects on microorganism communities that may lead to a reduction in the region’s role as a reservoir for greenhouse gas. The Amazon rainforest is the largest terrestrial reservoir or “sink” for carbon dioxide, a gas that has been linked to climate change. Through photosynthesis, the Amazon absorbs 1.5 billion tons of carbon dioxide from the...

WASHINGTON, Dec. 4, 2013 /PRNewswire/ -- Brazil, South America's largest nation, is home to the world's largest tropical rain forest. The Amazon River Basin holds 20% of the world's freshwater and produces 20% of its oxygen. It plays a major role in stabilizing the earth's ecosystem. But that balance is shifting. Production and profit for a fast growing economy jeopardizes the preservation of Amazonia. (Photo: http://photos.prnewswire.com/prnh/20131204/PH27940 ) "Tipping Point:...

Amazon Rain Forest Drought Resistant
2013-11-14 13:25:00

Lee Rannals for redOrbit.com - Your Universe Online Scientists writing in the Journal of Climate claim the Amazon rain forest may be more resilient in its ability to cope with dry conditions than previously believed. Researchers from the University of Exeter and Colorado State University used a computer model to demonstrate that the Amazon rainforest may be able to withstand periods of drought better than what previous climate models had predicted. During the study, researchers removed...

Amazon Deforestation Could Mean Droughts For Western United States
2013-11-07 12:22:13

Princeton University In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires. The researchers report in the Journal of Climate that an Amazon stripped bare could mean 20 percent less rain for the coastal...

Seasonal Drying In The Amazon Has Greater Impact Than Thought
2013-10-22 07:05:04

redOrbit Staff & Wire Reports - Your Universe Online New research suggests that the southern part of the Amazon Rainforest faces a higher risk of dieback (the gradual dying of plant shoots beginning at the tip) as a result of seasonal drying than reported by climate models used by the most recent Intergovernmental Panel on Climate Change (IPCC). Furthermore, University of Texas at Austin Jackson School of Geosciences professor Rong Fu and her colleagues report that severe loss of...

The Amazon Rainforest (known as Floresta Amazônica or Amazônia in Portuguese, and Selva Amazónica or Amazonia in Spanish), also known as Amazonia, or the Amazon Jungle, is a moist broadleaf forest that covers almost all of the Amazon Basin in South America. The basin consists of 1.7 billion acres, of which 1.4 billion acres is rainforest. This rainforest covers nine nations (Brazil, Peru, Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana). Brazil contains...
