Forests face climate change tug of war

November 21, 2019

In a world of rising levels of atmospheric carbon dioxide, plants should be happy, right? Experiments have shown that, yes, increased carbon dioxide does allow plants to photosynthesize more and use less water. But the other side of the coin is that warmer temperatures drive plants to use more water and photosynthesize less. So, which […]



U forest ecologist wins prestigious Packard Fellowship

October 15, 2018

William Anderegg, an assistant professor of biology, has received one of 18 Packard Fellowship for Science and Engineering from the David and Lucile Packard Foundation for his research on the effects of climate change and drought on forests. Packard Fellows receive a five-year, $875,000 grant to pursue research directions of their choosing. The Packard Foundation […]



Diverse forests are stronger against drought

September 17, 2018

Diversity is strength, even among forests. In a paper published in Nature, researchers led by University of Utah biologist William Anderegg report that forests with trees that employ a high diversity of traits related to water use suffer less of an impact from drought. The results, which expand on previous work that looked at individual […]



What it takes to recover from drought

August 3, 2017

Drought-stricken areas anxiously await the arrival of rain. Full recovery of the ecosystem, however, can extend long past the first rain drops on thirsty ground. According to a study published August 10 in Nature, the length of drought recovery depends on several factors, including the region of the world and the post-drought weather conditions. The […]



Drought’s lasting impact on forests

July 30, 2015

In the virtual worlds of climate modeling, forests and other vegetation are assumed to bounce back quickly from extreme drought. But that assumption is far off the mark, according to a new study of drought impacts at forest sites worldwide. Living trees took an average of two to four years to recover and resume normal […]
