Research network on phenotypic plasticity

The 3715 Phenotypic Plasticity research network (PlasPhen) is a French research network funded by the CNRS, on the theme of phenotypic plasticity. Phenotypic plasticity can be broadly defined as the response of phenotypes to their developmental or expression environment, for a given genotype. The objective of this network is to promote exchanges between researchers and academics based in France, whose work deals with phenotypic plasticity, its genetics and its evolution. The diversity of phenotypes, environments, and organisms studied in this network is illustrated by the word cloud above, made in real-time by the participants of the 2020 meeting of the network and available on the website of the network:

This GDR is scientifically co-led by Luis-Miguel CHEVIN (CEFE CNRS, Montpellier) and Vincent Debat (ISYEB MNHN, Paris), and administratively managed by the CEFE, in Montpellier. This is his second term for a period of 5 years (2019-2023), following a first term of 4 years (2015-2018).

The LEMAR members who are mainly involved in this GDR are: Guy Claireaux, Gregory Charrier, David Mazurais, Karine Salin, Arianna Servili, Jose Zambonino.

ECOBIM network

Studying chemical contamination and its effects

Since 2004, the international French-speaking network ECOBIM has brought together about 120 people from 30 research teams in bilateral collaborative actions in the field of ecotoxicology of aquatic environments on 2 axes, trans-Atlantic and trans-Mediterranean. The Network also counts among its members actors from the economic and cultural world: aquaculture resource operators, parks, aquariums,…. Ecotoxicology must adapt to the changing context of environmental chemical contamination (new molecules, interactions with climate change, etc.) by developing new skills in environmental assessment tools and methods. The joint approach along the continuums is promoted, through work on all anthropized aquatic ecosystems: mainly rivers and large estuaries. This network also aims to contribute to academic training at doctoral and pre-doctoral level through a well-established presence of teams in European and North American universities, but also to contribute to informing the public about the environmental consequences of pollution.

The main objectives of the network are:

  • acquire scientific knowledge on new forms of chemical contamination by promoting a multidisciplinary approach between biologists and chemists
  • promote their application to the operational component of monitoring programmes, in particular by harmonising methods of data analysis and exploitation
  • develop relevant biological models for monitoring aquatic environments
  • promote in situ observation by organizing joint work on internationally important workshop sites
  • access shared analytical means and heavy experimental means

The ECOBIM Network in a few actions

– Coordination of bi-lateral research projects funded by: ANR, NSERC, OSPAR, Franco-Quebec Cooperation Programs,…

– Scientific animation

  • member mobility :stays of students, researchers, post-doctoral fellows
  • scientific meetings : methodological workshops (immunotoxicology, genotoxicology,…) since 2004 ; annual network facilitation conferences since 2006
  • multi-annual environmental assessment workshops on remarkable sites (St. Lawrence Maritime, Saguenay Fjord, Baie de Seine, Rade de Brest,…)

– Training through research : co-supervision of Master’s/Master’s students ; supervision of co-supervised doctorates

– Development of Digital Training Support

GDR “Polymers and Oceans”

GDR-plolymeres et Ocean

The environmental issues related to the presence of plastics are now unanimously recognized. The national (governments) and international (European Union, United Nations) institutions have taken action to better understand the consequences of the presence of these plastic debris in the environment and to try to reduce their releases

The mission of the GDR “Polymers and Oceans”, recently created under the aegis of the CNRS, is to federate the French scientific community (composed by chemists, physicists, biologists, ecologists, ecotoxicologists, oceanographers, economists and sociologists) working on the fate of plastics in the environment to support the emergence of multi-scale and new interdisciplinary research.

The main objectives of this GDR are:

  • to define the main scientific questions and methodological obstacles around this topic;
  • to structure very diverse scientific communities and facilitate the establishment of scientific and technical collaborations between disciplinary fields to support multidisciplinary approaches that are essential to meet the challenges of this topic;
  • to promote collaboration between academic research and industrial research/innovation in relation to competitiveness clusters (e.g. Brittany-Atlantic and Mediterranean MER Poles, IAR) and learned societies (e.g. SFP, SCF, GFP) ;
  • play an active role in the implementation of new experimental protocols to assess the fate of polymers in the aquatic environment ;
  • create an information exchange platform offering an open window to respond to the many requests from economic actors, the media, NGOs and politicians and influence institutional prospects ;
  • participate in the dissemination of scientific knowledge acquired through the organization of an annual national conference and thematic schools.
