Plants can camouflage odours to avoid being eaten: Study 

#GS3 #Environment 

Plants in dense tropical forests have evolved to emit similar odours to avoid being eaten by insects, a new study has said. 

  • Researchers from Europe and North America studied 28 species of insects and 20 species of plants in Chamela-Cuixmala, a tropical forest reserve on the western coast of Mexico. 
  • They collected the odours of the plants in silicon tubes that were brought back to the Royal Botanical Gardens in Kew, London, to be studied. 
  • The scientists then used a combination of ‘information theory’ that is used to understand communication patterns in humans and existing understandings of evolutionary biology to reach their conclusion.
