Research identifies climate-change refugia in dry-forest region

Several indicators point to the adverse impacts of climate change on the planet's vegetation, but a little-known positive fact is the existence of climate-change refugia in which trees are far less affected by the gradual ...

Limited value of tree plantations for biodiversity conservation

In light of declining natural forests, tree plantations may seem like a good way to replace forest habitats. But what are the possible benefits of these plantations for biological diversity? A team of researchers led by led ...

Old-growth forest carbon sinks overestimated

The claim that old-growth forests play a significant role in climate mitigation, based upon the argument that even the oldest forests keep sucking CO2 out of the atmosphere, is being refuted by researchers at the University ...

Climate impacts drive east-west divide in forest seed production

Younger, smaller trees that comprise much of North America's eastern forests have increased their seed production under climate change, but older, larger trees that dominate forests in much of the West have been less responsive, ...

Forests go into growth 'overdrive' to recover from drought

One in 12 people could face severe drought every year by 2100, according to a recent study. And water stored on two-thirds of the Earth's land surface will shrink as the climate warms. As plant ecologists, we're concerned ...

Evapotranspiration in an arid environment

Evapotranspiration is an important process in the water cycle because it is responsible for 15% of the atmosphere's water vapor. Without that input of water vapor, clouds could not form, and precipitation would never fall. ...
