EWRS webinar series 2021 Part 5: Weed invasions and Climate Change
Presentations by Dr. Guillaume Fried, ANSES, France and Dr. Yan Sun, University of Fribourg, Switzerland
Online webinar 14:00 - 15:30 CET, 31st of March 2021
EWRS webinar series 2021
This year, a group of EWRS members got together to develop a webinar series covering a wide range of innovative topics that are of interest to everyone involved in weed science and management. Join our webinars to follow a stimulating discussion about the latest research tools and management practices for sustainable weed management. You can download the full programme HERE.

On the 31rd of March, Dr. Guillaume Fried, Anses, France, will present "Ambrosia trifida as an emerging invasive weed and the EPPO Pest risk analysis for invasive species" and Dr. Yan Sun, University of Fribourg, Switzerland, will talk about the "Evolutionary effect of climate change and plant invasions".
14:00 - 14:45
Dr. Guillaume Fried - ANSES, France:
Pest Risk Analysis or how to avoid the introduction and spread of new invasive alien plants. A case-study with Ambrosia trifida in Europe
I am a botanist and weed ecologist working at Anses (French Plant Health Laboratory). My research work is aimed at assessing the impact of human activities on the environment.
I study two main models: i) the effects of alien plants introduction and their impact on wild vegetation or crops, and ii) the impact of agricultural practices on the flora of cultivated fields and field borders. I use and test hypotheses of community ecology with functional approaches.
Phytosanitary regulations are part of the preventive strategies that can help to avoid the introduction of new invasive alien weeds and/or to organise an official and coordinated control of recently introduced weeds that are still localised. The case of Ambrosia trifida will be developed on the basis of the recent pest risk analysis carried out on this species by the European and Mediterranean Plant Protection Organisation (EPPO).
14:45 - 15:30
Dr. Yan Sun – University of Fribourg, Switzerland:
Rapid evolution of a plant invader in response to biocontrol and climate change
2017-present University of Fribourg, Switzerland, Postdoc
2016-2017 University of Tübingen, Germany, Postdoc
2014-2015 University of California, Berkeley, USA, Postdoc
2009-2013 University of Fribourg, Switzerland，PhD
In 2016, we started an experimental evolution study to get insights into the evolvability to a biocontrol insect and global warming of the European plant invader, Ambrosia artemisiifolia. I will present the genomic and metabolomic differentiations, some of our phenotyping results of the offspring plant performance and resistance in common environment, and preliminary results of soil abiotic property and microbial differences among different field selection treatments.
