Scientific goals

Three group publications issued from Workshops organized by the GDR.

Marine Protected Areas and Connectivity

Lagabrielle, E., Crochelet, E., Andrello, M., Schill, S.R., Arnaud-Haond, S., Alloncle, N., Ponge, B., 2014. Connecting MPAs - Eight challenges for science and management. Aquatic Conservation: Marine and Freshwater Ecosystems 24, 94-110.


Taxonomy et Connectivity

Session proposal and chairing, and talks with the French Agency for MPAs at the world congress on MPAs IMPAC 2013 in Marseille

Session: Deepening coherence and connectivity of regional networks: initiatives


Alloncle, N., M. Andrello, and S. Arnaud-Haond. 2013. Collaboration between scientists and managers to address connectivity issues within MPA network in Towards ecologically representative and well connected regional networks.

Arnaud-Haond, S. 2013. Genetic, biogeographic representativeness and connectivity in Understanding connectivity for MPA planning.


Organization of a session  (Katell Guizien &Sophie Arnaud-Haond) at the congress of the American Society for Limnology and Oceanography  (ASLO, Granada-Spain, 2015):

Multi-methods connectivity estimates to improve Marine Protection Designs


“Mini projets collaboratifs”

Four collaborative projects financed by Ifremer in 2013 to trigger multidiciplinary and partners collaboration


- SPARTAGEN: Differential adaptation to marine and lagoon environments for the seabream? CNRS Sète, MARBEC. Two articles being drafted on life cycle and population structure of seabreams.

- Genetic structure of a species with high gene flow potential in an isolated and fragmented metapopulation: Mytilus species in Kerguelen archipelago. IMBE Marseille, Ifremer la Tremblade, CNRS Sète. Results being acquired


- Contemporary and historical connectivity between the Atlantic and the Mediterranean : the case of temperate cnidarians. IMBE Marseille, MARBEC Sète, CCMar Faro (Portugal). One publication submitted.


- Habitat fragmentation and local scale connectivity : the case of cave Mysidacea in Marseilles region. IMBE Marseille, Equipe Génétique de l'Adaptation en milieux Extrêmes, Roscoff.


Projects built:

Modelling and population genetics:

  • Project Connect7 (Funded by the Region Languedoc Roussillon, coordinator CNRS Nicolas Bierne) initiated before the GDR
  • Project ATLAS (European H2020 with deadline in june 2015, responsable of WP Connectivity and Interface with the WP on Oceanographic and Habitat Modelling Ifremer S. Arnaud-Haond)
  • Projects AMOP SELPAL and REPAST (Project Funded by « France Filière Pêche », coordinator Ifremer François Poisson)
  • Project HYDROGENCONNECT (HYDROdynamic networks, population GENetics and oceanic CONNECTivity) funded by ENVI-MED Regional Programme


Integration with the Agency for MPAs:

  • Collaboration Agency-Ifremer-CNRS on a one year project and report to synthetize knowledge on the importance of connectivity for MPAs
  • National project MarCoscope submitted for funding (2014) but not selected
  • Biodiversa project being prepared (deadline July 2015)



2.   Educational goals


Workshops “for the dumbs”


Organisation of 4 Workshops “for the dumbs”, with the objective of transferring knowledge to student and researchers on areas complementary of their expertise, in order to gain a critical appraisal of results and research published in complementary fields

4 Workshops in 2013-2014, including 75 PhD students, post-docs and researchers

  • Oceanographic Modelling (20)
  • Populations Genetics (15)
  • Otholitometry (20)
  • Marine Protected Areas : constrains and space for improvements (20)

Contribution of the GDR to students training


  • Use of the website MarCo to centralize information on Master modules
  • Interventions in 7 Masters or Doctoral modules: Paris MNHN, Sud et UPMC, La Rochelle, Marseille, Nice, Montpellier
  • Implication and exchange of PhD students (2) in the framework of the small projects funded in 2013
  • 40-50% of talks given by students and post-doc during the last annual meetings (Figure 1)

Figure 1 : Talks realized during annual meetings: 16 to 26 talks over two days with an increasing participation of students and post-docs (50%, or more in 2014)
