Ozone

Ozone affects plants, insects and microorganisms, and poses a threat to global biodiversity

According to a study co-authored by CREAF-based CSIC researcher Josep Peñuelas and published in Science Advances, increases in ozone in Earth’s atmosphere will be a danger to the biodiversity of the Mediterranean Basin, Japan and equatorial Africa by 2100.

Increased ozone levels reduce flowers' sex appeal

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.

Scientists study the chemical language of plants from the sky

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.
