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 ...
Being small has its advantages, if you are a leaf
(PhysOrg.com) -- The size of leaves can vary by a factor of 1,000 across plant species, but until now, the reason why has remained a mystery. A new study by an international team of scientists led by UCLA ...
Nutrient-rich forests absorb more carbon
The ability of forests to sequester carbon from the atmosphere depends on nutrients available in the forest soils, shows new research from an international team of researchers including the International ...
Studies suggest boreal forests can handle oilsands development
(Phys.org) —Ongoing work by University of Alberta researcher Scott Chang is providing cautious optimism about how forest soil and trees are coping with oilsands development in Northern Alberta.
Amazon rainforest more able to withstand drought than previously thought
New research suggests that the Amazon rainforest may be more able to cope with dry conditions than previously predicted. Researchers at the University of Exeter and Colorado State University used a computer ...
Plant production could decline as climate change affects soil nutrients
(Phys.org) —As drylands of the world become even drier, water will not be the only resource in short supply. Levels of nutrients in the soil will likely be affected, and their imbalance could affect the ...
Soils in newly forested areas store substantial carbon that could help offset climate change
Surface appearances can be so misleading: In most forests, the amount of carbon held in soils is substantially greater than the amount contained in the trees themselves.
Biologists unlock 'black box' to underground world: Research shows how tiny microbes make life easier for humans
(Phys.org)—A BYU biologist is part of a team of researchers that has unlocked the "black box" to the underground world home to billions of microscopic creatures.
Scientists reveal how soil and stone mixture determine Congo tree mix
Variations in the soil and stone beneath it are the biggest factor behind which trees grow where in the rainforests of the Congo basin, a new study has found.
NASA maps how soil nutrients affect plant productivity
(Phys.org)—A new analysis led by NASA's Jet Propulsion Laboratory, Pasadena, Calif., has estimated how much the growth of plants worldwide is limited by the amount of nutrients available in their soil. ...
Too little nitrogen may restrain plants' carbon storage capability, research shows
Plants' ability to absorb increased levels of carbon dioxide in the air may have been overestimated, a new University of Minnesota study shows.
Forest mortality and climate change: The big picture
Over the past two decades, extensive forest death triggered by hot and dry climatic conditions has been documented on every continent except Antarctica. Forest mortality due to drought and heat stress is expected to increase ...
Rising carbon dioxide in atmosphere also speeds carbon loss from forest soils: study
Elevated levels of atmospheric carbon dioxide accelerate carbon cycling and soil carbon loss in forests, new research led by an Indiana University biologist has found.
European Arctic forests expansion could result in carbon dioxide release: study
Carbon stored in Arctic tundra could be released into the atmosphere by new trees growing in the warmer region, exacerbating climate change, scientists have revealed.
