Vines add surprising variable to tropical forest carbon storage

New study shows lianas dramatically reduce carbon sequestration by crowding out, killing trees

Just when we thought we were getting closer to understanding tropical forests’ tremendously valuable service of sucking carbon from the air and socking it away in tree trunks and other biomass, along comes a new variable: woody vines. (more…)

UW students create, harvest fog in campus ‘hoop house’

In the fog chamber, a thick cool mist rolls from one end to the other blurring glasses, wetting caps and coats and sending water dripping down the latest test panel.

University of Washington students have been testing low-cost materials capable of harvesting water from fog in a temporary “hoop house” next to the Botany Greenhouse. They create the fog with a specially adapted power washer and record how much water condenses and drips off various panels of low-cost materials, such as shade cloth. (more…)

Why Are Vines Overtaking the American Tropics?

A Million-Dollar Question

Sleeping Beauty’s kingdom was overgrown by vines when she fell into a deep sleep. Researchers at the Smithsonian in Panama and the University of Wisconsin at Milwaukee received more than a million dollars from the U.S. National Science Foundation to discover why real vines are overtaking the American tropics. Data from eight sites show that vines are overgrowing trees in all cases. 

“We are witnessing a fundamental structural change in the physical make-up of forests that will have a profound impact on the animals, human communities and businesses that depend on them for their livelihoods,” said Stefan Schnitzer, research associate at the Smithsonian Tropical Research Institute in Panama and associate professor at the University of Wisconsin at Milwaukee.  (more…)
