Increased ozone levels reduce flowers’ sex appeal

17 de September 2015Anna Ramon Revilla

New research finds that as climate change increases ozone levels, pollinators will have a harder timing finding plants that feed them. That’s going to be a problem for the bees that pollinate a third of the world’s food supply. Flowers and other plants rely on microscopic scent molecules to attract the bees and other pollinators that feed on them. Climate change is going to disrupt that process, mostly because of ground-level ozone, which is projected to increase over the coming decades. The study, published in the journal New Phytologist, found that flowers’ fragile scent molecules break down more quickly as they are exposed to greater levels of ozone. >> Read the full article from Takepart.com here

Scientists study the chemical language of plants from the sky

10 de October 2013Anna Ramon Revilla

A study carried out by scientists at the CREAF and the CSIC has shown that the reflectance PRI index allows for the quantification of gasses emitted by plants in order to communicate or in situations of stress.  This index is calculated by measuring the light that vegetation reflects with the help of photosensors on planes or with satellite images.
