Long-term fate of tropical forests may not be so dire
Long-term fate tropical forests may not so dire
2017/7/19
Tropical rainforests are often described as the “lungs of the earth,” able to essentially inhale carbon dioxide from the atmosphere and exhale oxygen in return. The faster they grow, the more they mit...
Research links decline in hemlock forests to changes in water resources
decline hemlock forests changes in water resources
2017/4/27
An insect infestation that is killing hemlock trees in New England forests is having a significant impact on the water resources of forested ecosystems that provide essential water supplies to one of ...
Dust contributes valuable nutrients to Sierra Nevada forest ecosystems
Dust contributes valuable nutrients Sierra Nevada forest ecosystems
2017/3/30
But dust from as close as California's Central Valley and as far away as Asia's Gobi Desert provides nutrients, especially phosphorus, to vegetation in the Sierra Nevada Mountains, a team of scientist...
How Much Drought Can a Forest Take?
Drought Forest
2017/2/16
Why do some trees die in a drought and others don’t? And how can we predict where trees are most likely to die in future droughts?Scientists from the University of California, Davis, and colleagues ex...
Tree-bark thickness indicates fire-resistance in a hotter future
Tree-bark thickness fire-resistance hotter future
2017/2/16
A new study has found that trees worldwide develop thicker bark when they live in fire-prone areas. The findings suggest that bark thickness could help predict which forests and savannas will survive ...

2016/8/11
Earlier snowmelt periods associated with a warming climate may hinder subalpine forest regulation of atmospheric carbon dioxide (CO2), according to the results of a new University of Colorado Boulder ...
Neutralizing acidic forest soils boosts tree growth,causes spike in nitrogen export
Neutralizing acidic soils tree growth causes spike nitrogen export
2016/7/4
A legacy of acid rain has acidified forest soils throughout the northeastern US, lowering the growth rate of trees. In an attempt to mitigate this trend, in 1999 scientists added calcium to an experim...

2016/3/28
China’s sweeping program to restore forests across the country is working. The vast destruction of China’s forests, leveled after decades of logging, floods and conversion to farmland, has become...
New insights into the seasonality of Amazon's evergreen forests
seasonality Amazon evergreen forests
2016/3/2
Sometimes you can't see the forest for the trees. In the Amazon, the opposite is true: without truly seeing the trees, you can't "see" the forest and understand the seasonal patterns of photosynthesis...
Forests nationwide are feeling the heat from increasing drought and climate change, according to a new study by scientists from 14 research institutions.
"Over the last two decades, warming temperatu...
Air Quality and Ozone Pollution Models for Forested Areas May Be Too Simple
Air Quality Ozone Pollution Models Forested Areas Too Simple
2015/10/13
A new study assessing the influence of species diversity of canopy trees on the amount of ozone precursors a forest emits suggests that atmospheric chemistry models in use now may underestimate the im...
