The project also partly supports the implementation of the Directive 2008/56/EC of the European Parliament and of the Council of 17 June 2008 establishing a framework for community action in the field of marine environmental policy (Marine Strategy Framework Directive - MSFD) highlighting descriptors 1 (biological diversity), 2 (non-indigenous species) and 6 (sea floor integrity).

Duration of the project: 01/03/2013 - 29/02/2016 - extented by ANR untill 31/10/2016 for CNRS?

CIGESMED’s goal is to understand the links between natural and anthropogenic pressures and ecosystem functioning to define and maintain the Good Environmental Status (GES?) of the Mediterranean Sea, by studying the typical, complex and not well known habitats built by calcareous encrusting algea, the coralligen. [1]

An integrated approach of complexity of coralligen will permit to mutualize and visualize large data collections, and manage knowledge to study ecosystems. Indicators, from communities to infra-specific level (DNA), will be co-constructed and tested by scientists, marine natural parks and reserves, and through the implementation of a “citizen science” network. The use of trees of knowledge as tools to sort, organize and illustrate very large heterogeneous sets of data will constitute an original approach.
The outcome will be an integrative assessment of the GES within the Marine Strategy Framework Directive.

CIGESMED gathers scientists from France, Greece and Turkey, making it possible to access to sites and to work on the same issues in both the northwestern Mediterranean basin and the Aegean-Levantine one. Ten laboratories of marine ecology are involved. It will also involve observers from other Mediterranean countries.
It is coordinated by the IMBE, a unit of research of Aix-Marseille University, CNRS-INEE, IRD and University of Avignon.


[1(“… There is no real consensus among scientists studying benthic communities in the Mediterranean Sea about what a coralligenous habitat? is.

"...The main criterion used to define the coralligenous habitat is the presence of a bioherm of coralline algae grown at low irradiance levels and in relatively calm waters. This bioherm is always very complex in structure and, in fact, allows the development of several kinds of communities (Laborel 1961, Laubier 1966), including those dominated by living algae (upper part of the concretions), suspension feeders (lower part of the concretions, wall cavities and overhangs), borers (inside the concretions) and even soft-bottom fauna (in the sediment deposited in cavities and holes). Therefore, the coralligenous habitat should be considered more as a sub- marine landscape or community puzzle rather than a single community. …”

Hi! I know this is kinda off topic but I was wondering which blog platform are you using for this website? I'm getting fed up of Wordpress because I've had problems with hackers and I'm looking at alternatives for another platform. I would be awesome if you could point me in the direction of a good platform.
