About flowers, insects and networks

7 de February 2018Francisco Lloret

Nature establishes relationships between species and organisms, forming a very complex network where often great-interconnected nodes appear. They are called 'hubs'. But humans also create this kind of networks, such as airports as nodes and flights as connections.

Flowers and butterflies lose their synchronicity due to climate change

18 de July 2016Verónica Couto Antelo

A study finds that high temperatures and low rainfall cause a timing mismatch between the flowering period of plants and the time of flight of butterflies. The moments of maximum florescence and butterfly abundance are separated by a mean time of 70 days, increasing in years with marked drought.

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

Flowers pollinized by insects are more fragrant than those pollinized by the wind

1 de July 2015Marina Torres Gibert

A study published in the journal Biochemical Systematics and Ecologyand carried out by a team of CREAF researchers has shown that pollination by insects increases emissions of the molecules that give flowers their odors. Flower fragrances are needed to attract insects and guarantee the exchange of pollen with other flowers.
