Ophraella and Ambrosia pollen flying on TV (6-minute videos)

Summer 2014, a television crew visited the University of Fribourg research facilities in Switzerland, and two field sites in Italy where an international team led by Heinz Müller-Schärer has been investigating the effects of the ragweed leaf beetle Ophraella communa.

Watch the resulting movies that were broadcast on the popular science shows  Nano (Switzerland) or Einstein (Austria, Germany, Switzerland). The potential benefits for the control of ragweed, and the potential risks for other plant species are presented.

The movies are in German, but you can anyway enjoy the images of flying beetles and Ambrosia pollen without understanding the spoken words! The websites contain additional interviews on the Ambrosia problem.

Movie: Invasive alien species – a growing threat in Europe

Invasive alien species (IAS) cost the EU an estimated EUR 12 billion per year, prompting the European Commission to push for an EU-wide approach to tackle the issue. The phenomenon, which occurs when plants and animals are deliberately or unintentionally introduced by human action to a new environment where they establish, reproduce and proliferate, is causing serious problems for biodiversity. The dedicated legal instrument aims to tackle the problem through a new harmonised system and a shift from “cure” to “prevention”.
