Fire And Drought May Push Amazonian Forests Beyond Tipping

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...

H&M and Zara/Inditex Partner with Canopy to Transform Clothing's Impacts on Species, Forests and Climate VANCOUVER, April 2, 2014 /PRNewswire/ - Today, the world's two largest clothing brands are making commitments to eliminate ancient and endangered forests from all of their rayon and viscose clothing. The companies, retail and design leaders H&M and Zara/Inditex, developed these new purchasing commitments in partnership with award-winning environmental organization Canopy...

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...

Forest Model Predicts How Trees Compete For Canopy Space
2014-02-20 11:53:17

Brown University Out of an effort to account for what seemed in airborne images to be unusually large tree growth in a Hawaiian forest, scientists at Brown University and the Carnegie Institution for Science have developed a new mathematical model that predicts how trees compete for space in the canopy. What their model revealed for this particular forest of hardy native Metrosideros polymorpha trees on the windward slope of Manua Kea, is that an incumbent tree limb greening up a given...

As they complete their PhDs, a team of Stanford graduate students is creating Inian Islands Institute, a field school dedicated to a unique brand of sustainability education at an amazing coastal property in the heart of the Alaskan Wilderness. Palo Alto, California and Inian Islands, Alaska (PRWEB) December 06, 2013 A group of four Stanford environmental science graduate students, led by Southeast Alaska native Zachary Brown, has launched a fundraising campaign to build a field...

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...

Amazon Forestry Survey Finds Roughly 16,000 Tree Species
2013-10-18 04:14:34

redOrbit Staff & Wire Reports - Your Universe Online Researchers have discovered that there are nearly 400 million individual trees in the Amazon, and while there are over 16,000 different types, approximately half of them belong to just 227 unique species. Those startling findings are the result of a study, published Thursday in the journal Science, in which more than 100 scientists, taxonomists and students from 89 global institutions set out to determine the total number of trees...

NASA Satellites Calculate Damage Of Previously Undiscovered Amazon Wildfires
2013-06-09 07:46:38

redOrbit Staff & Wire Reports — Your Universe Online A previously undetected type of wildfire occurring in the Amazon region is responsible for far more rainforest loss than deforestation in recent years, NASA scientists have discovered using innovative new satellite techniques. Known as “understory fires,” these wildfires have long remained undetected because they are located below the forest treetops, explained Tamarra Kemsley of Nature World News. However,...

Rainforests May Be Resilient To Climate Change
2013-03-11 04:51:35

redOrbit Staff & Wire Reports - Your Universe Online Tropical forests may be more resistant to the effects of greenhouse gas emissions than previously believed, according to a new study published online this week in the journal Nature Geoscience. In what Olive Heffernan of Nature refers to as “the most extensive study of its kind,” researchers from the US, the UK, Australia and Brazil created a simulation of the impact that carbon-based emissions would have on tropical...

Tree Death In Amazon Much Higher Than Previously Believed
2013-01-29 12:28:36

Alan McStravick for redOrbit.com - Your Universe Online If a tree falls in the forest and no one is around, does it have a direct impact on climate change? A new study from the Lawrence Berkeley National Laboratory (Berkeley Lab) set out to answer this question. Forests are critical to the equilibrium of Earth´s climate since they absorb large quantities of the greenhouse gas carbon dioxide directly from our atmosphere. The death of a tree, however, reverses the flow of carbon and...

Forest Gardening
2013-07-31 15:46:47

Forest gardening is a woodland ecosystem that requires little maintenance. Forest gardening is a form of intercropping that is a seven tier, layering system utilizing the space from the sub-ground up to the canopy in order to provide high yielding food production for human consumption in wooded areas. Layering utilizes the photosynthesis to the maximum benefit for each tier within the forest garden. The canopy level consists of the tallest fruit/nut trees with dwarf trees in the...

Olympic National Park

Olympic National Park is located in the state of Washington, in the Olympic Peninsula, in the United States. The park holds 922,650 acres of land that was once inhabited by Native Americans. Most of the tribes were wiped out once European explorers introduced diseases into the area. In the late nineteenth and early twentieth centuries, the logging industry boomed, but the public began to express concerns of over logging in the 1920’s. However, the first proposal to establish the area as a...

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...
