Résumé : This report synthesizes the discussions of a workshop organized during the "Liteau II-AMP" project , a collaborative project involving scientists and MPA managers that aimed at developing diagnostic and exploratory tools for the assessment of Marine Protected Areas performance. This 2004-2006 project was funded by the Liteau program (http://www.liteau.ecologie.gouv.fr) of the French Ministry of Ecology and Sustainable Development. The workshop was organized on 30th November and 1st December at the EPHE (University of Perpignan, France). It was aimed at gathering a number of scientists and managers involved in MPA in France and in overseas French territories, in order to discuss the issue of interactions between managers and scientists in the context of MPAs. After this fruitful workshop, we felt it was useful to produce a synthesis about interactions between scientists and managers for the MPA or MPA projects present at the workshop. The topics discussed include how to interact, the degree of involvement of both sides in interactions, research versus monitoring, gaps and expectations.
Préambule : Cette synthèse s'inscrit dans le projet « Développement d'Outils Diagnostics et Exploratoires d'Aide à la Décision pour Evaluer la Performance d'Aires Marines Protégées », projet financé par le programme Lit'eau II du Ministère de l'Ecologie et du Développement Durable. L'objet de la réunion des 30 novembre et 1er décembre 2004 à l'EPHE de Perpignan était de rassembler un certain nombre de personnes impliquées dans la gestion d'Aires Marines Protégées en France et outremer, ainsi que des scientifiques concernés par la problématique des Aires Marines Protégées afin de discuter des relations et interactions entre scientifiques et gestionnaires dans ce domaine. A l'issue de cette réunion, il s'agissait d'établir un document synthétique qui ferait le point sur les interactions entre scientifiques et gestionnaires en ce qui concerne les AMP ou projets d'AMP représentés : mode de fonctionnement, degré d'implication, études plus recherche versus suivis périodiques, besoins couverts, non couverts, anticipation des évolutions en la matière. Ce document constitue une synthèse des différents éléments qui ont pu émerger des discussions de ces deux jours et des contributions -avant et après la réunion- de différents participants.

Résumé : This second mollusc physiology meeting has being organized jointly by LEMAR (IUEM: European Institute for Marine Studies) and LPI (Ifremer: French Institute for the Exploitation of the Sea), as both laboratories conduct research in this field. Physiomar 08 followed the very successful workshop 'Physiological aspects of reproduction and nutrition in marine mollusks' held in La Paz (Mexico) in November 2006 under the guidance of Maria Concepcion Lora Vilchis and Elena Palacios Metchenov from CIBNOR. This year's meeting has focus on Reproduction, Growth, Nutrition and Genetics and genomics of marine molluscs, and included a specific session on the effects of climate change on mollusc physiology: Global change. This conference has served as a forum for the communication of recent advances in all aspects of the physiology in molluscs. Researchers, students, stakeholders and mollusc farmers have had the opportunity to communicate personally in a friendly environment with leaders in the field. This meeting aimed to provide a vehicle for continuing exchanges, cooperation, and collaboration in the field of the physiology of marine molluscs to better understand their adaptation ability in a changing environment, their ecological significance, and to promote their sustainable culture.

Résumé : International audience
The purpose of this study is to identify links between the geothermal context and the conceptions in different initial teachers training, from the Caribbean and North America. The Caribbean Islands are located in a subduction zone, creating a great potential for geothermal energy. In Guadeloupe, this potential has been harnessed and a geothermal power plant produces about 5% of the local demand for electricity. It is called high temperature geothermy. In Quebec the bedrock mainly consists of ancient Precambrian rocks from the Canadian Shield, which does not allow for electricity production. The geothermal heat is used to regulate the temperature in buildings, to create spars, to grow crops and other purposes. It is called low temperature geothermy. This design-based research (Sandoval, W. et Al., 2004) takes part in the contextualization of sciences education research works (Blanchet, P. et Al., 2009, Anciaux, F. et Al., 2013) and in the continuation of the Gounouy project (Fecil, S. et Al., 2014). A project-based learning on geothermal energy has been set up with two groups of initial teachers training from the Université du Québec à Montréal (UQAM) and from the French West Indies University (UA). The purpose is to create collaborations between each group in order to enable them to encounter, recognize and formulate their conceptions. Further, they will collectively elaborate a more complex understanding of conceptions about geothermy. More specifically, the design used in this experiment aims to highlight context effects (Merlo-Leurette, S., Forissier, T., 2009). Context effects are pedagogical events occurring when there is a clash between the different conceptions of students, observed uring courses regarding different problematics related to geothermal energy. Communications via videoconferences were arranged so that the counterpart teams may discuss their investigative findings. Videos from the exchanges have been collected, as well as weekly summaries about student’s accomplishment, ideas, questions and feelings. Pre-test and post-test questionnaires on geothermal energy were submitted at the beginning and at the end of the project, to compare conceptions before and after the learning process. Collected data enables to bring out the student’s contextuality. Therefore, they highlight context effects, due to the differences between the geothermal contexts in Guadeloupe and in Montreal.This study is supported by the Geotref project.

Résumé : International audience
The Developmental Origins of Health and Disease (DOHaD) paradigm is one of the most rapidly expanding areas of biomedical research. Environmental stressors that can impact on DOHaD encompass a variety of environmental and occupational hazards as well as deficiency and oversupply of nutrients and energy. They can disrupt early developmental processes and lead to increased susceptibility to disease/dysfunctions later in life. Presentations at the fourth Conference on Prenatal Programming and Toxicity in Boston, in October 2014, provided important insights and led to new recommendations for research and public health action. The conference highlighted vulnerable exposure windows that can occur as early as the preconception period and epigenetics as a major mechanism than can lead to disadvantageous "reprogramming" of the genome, thereby potentially resulting in transgenerational effects. Stem cells can also be targets of environmental stressors, thus paving another way for effects that may last a lifetime. Current testing paradigms do not allow proper characterization of risk factors and their interactions. Thus, relevant exposure levels and combinations for testing must be identified from human exposure situations and outcome assessments. Testing of potential underpinning mechanisms and biomarker development require laboratory animal models and in vitro approaches. Only few large-scale birth cohorts exist, and collaboration between birth cohorts on a global scale should be facilitated. DOHaD-based research has a crucial role in establishing factors leading to detrimental outcomes and developing early preventative/remediation strategies to combat these risks

Résumé : International audience
Marine micro-and macroorganisms are well known to produce metabolites with high biotechnological potential. Nearly 40 years of systematic prospecting all around the New Caledonia archipelago and several successive research programs have uncovered new chemical leads from benthic and planktonic organisms. After species identification, biological and/or pharmaceutical analyses are performed on marine organisms to assess their bioactivities. A total of 3582 genera, 1107 families and 9372 species have been surveyed and more than 350 novel molecular structures have been identified. Along with their bioactivities that hold promise for therapeutic applications, most of these molecules are also potentially useful for cosmetics and food biotechnology. This review highlights the tremendous marine diversity in New Caledonia, and offers an outline of the vast possibilities for natural products, especially in the interest of pursuing collaborative fundamental research programs and developing local biotechnology programs.

Résumé : La tuberculose (TB), maladie infectieuse contagieuse, est causée par une mycobactérie appartenant au complexe Mycobacterium tuberculosis (MTBC). Malgré de nombreuses campagnes de vaccination par le BCG (Bacilles de Calmette et Guérin) et les traitements antituberculeux, on observe une réémergence de la maladie depuis les années 80. Ce bouleversement s’explique par la coïnfection avec le virus du VIH/SIDA, la désorganisation des systèmes de santé et par l’apparition des bactéries résistantes aux principaux antibiotiques antituberculeux. Dans ce contexte une meilleure connaissance des mouvements et de l’évolution des clones circulants du bacille tuberculeux permettrait de détecter plus rapidement et de façon plus pertinente l’émergence d’épidémies. Le contrôle et la surveillance de la maladie représentent des moyens essentiels pour lutter contre l’expansion mondiale de la tuberculose. C’est ainsi que l’unité de la Tuberculose et des Mycobactéries de l’Institut Pasteur de la Guadeloupe (IPG) a mis en place une base de données de profils génotypiques pour l’étude de l’épidémiologie globale de la tuberculose. Dans le cadre de cette thèse, nous décrirons les méthodes de bioinformatique qui ont été utilisées pour la gestion et l’exploitation de la 6ème version (SITVIT2) de cette base de données des génotypes pour mieux comprendre l’évolution et la dissémination mondiale du bacille tuberculeux. Cette base intègre aussi plusieurs marqueurs moléculaires tels que les MIRU-VNTRs (« mycobacterial interspersed repetitive units-variable number of tandem repeats ») et le Spoligotype43 servant à mieux décrire et identifier les familles de profils génotypiques du MTBC. La banque de données SITVIT2 ne cesse d’évoluer, et elle contient actuellement des informations épidémiologiques sur 111 635 isolats cliniques. Cette base de données est consultable en ligne à l’adresse suivante : http://www.pasteur-guadeloupe.fr:8081/SITVIT2/. Nous avons également réalisé une base de données nommée SITVITBovis qui est dédiée à la tuberculose bovine. Cette base de données sera accessible à l’adresse : http://www.pasteur-guadeloupe.fr:8081/SITVIT_Bovis/. Parallèlement au développement et à la gestion des bases de données, ce travail de thèse s’est appuyé sur plusieurs études épidémiologiques et phylogéographiques mettant en corrélation les données disponibles sur la résistance aux médicaments ou les caractéristiques démographiques (dont le sexe, l’âge, le statut VIH, et l’origine du patient). Notre initiative de recherche permet ainsi d’améliorer la caractérisation phylogénétique détaillée des lignées du MTBC, ainsi que l’épidémiologie des clones en circulation, afin d’élaborer une cartographie géographique des isolats cliniques prédominants pour les bacilles tuberculeux principalement impliqués dans la maladie, à l’échelle nationale, régionale et mondiale. La superposition ultérieure de ces cartes avec des données sociopolitiques, économiques et démographiques obtenues auprès de Systèmes d’information géographique (SIG) ont permis de dresser un portrait précis des disparités actuelles par pays ou sous-région. Cette thèse représente une importante collaboration avec plusieurs équipes de chercheurs travaillant également dans le domaine de l’épidémiologie moléculaire de la tuberculose. L’objectif à long terme de ce travail, est d’optimiser la structure de la base, et de pérenniser l’enrichissement de celle-ci (notamment par l’automatisation et la facilité de la saisie de données). Une représentation optimale et une meilleure accessibilité des données de la base conforteraient les efforts faits pour le contrôle et la surveillance de la TB dans monde.
Tuberculosis (TB) is a contagious infectious disease caused by mycobacteria belonging to the Mycobacterium tuberculosis complex (MTBC). Despite numerous campaigns of vaccination by the BCG (Bacillus Calmette-Guérin) vaccine, and TB treatments, there was a resurgence of the disease since the 80s. This disruption is due to coinfection with HIV/AIDS, disorganization of health systems and the emergence of bacteria resistant to anti-TB drugs. In this context, a better understanding of the movements and changes of circulating clones of tubercle bacilli would detect faster and more relevant emerging epidemics. The control and monitoring of the disease are essential means to fight against the worldwide spread of tuberculosis. Thus the TB and Mycobacteria unit of the Pasteur Institute of Guadeloupe (IPG) has developed a database of genotypic profiles for the study of global epidemiology of tuberculosis.In this thesis, we discuss the Bioinformatical methods that have been used for the management and development of the 6th version (SITVIT2) of this database of genotypes to better understand the evolution and global dissemination of the tubercle bacillus. The database also includes several molecular markers such as MIRU-VNTRs (mycobacterial interspersed repetitive units- variable number of tandem repeats) and Spoligotype43 allowing a better description and identification of the families of genotypic profiles of Mycobacterium tuberculosis complex. SITVIT2 database is constantly evolving, and it currently contains epidemiological information on 111,635 clinical isolates. This database is available online at the following address: http://www.pasteur-guadeloupe.fr:8081/SITVIT2/. We also developed a database named "SITVITBovis", which is dedicated to bovine tuberculosis. This database will be accessible at: http://www.pasteur-guadeloupe.fr:8081/SITVIT_Bovis/.Alongside the development and management of databases, this work was based on several epidemiological and phylogeographic studies correlating data on drug resistance or demographic characteristics (including sex, age, HIV status, and the origin of the patient). Our research initiative is thus focused to further improve in depth phylogenetic characterization of MTBC lineages, as well as the epidemiological analysis of circulating clones to generate evidence-based geographical mapping of predominant clinical isolates of tubercle bacilli causing the bulk of the disease both at country and regional level. Further superposition of these maps with socio-political, economical and demographical available through Geographic Information Systems (GIS) allows to have a precise view of prevailing disparities at the level of country or sub-region. This thesis represents an important collaboration with several researchers teams also working in the field of molecular epidemiology of tuberculosis.The long-term goal of this work is to further optimize the database structure, and sustain enriching it (including automation and ease of data entry). Optimum performance and accessibility of data in the database would reinforce efforts to control and surveillance of TB in the world.

Éditeur(s) : Caught in the "fishing net" of information 14th Biennal EURASLIC Meeting 17-20 May, 2011, Lyon, France
Résumé : In addition to its promotion and conservation objectives, Archimer, Ifremer’s institutional repository, offers a wide range of bibliometric tools described in this document. As early as the recording stage, numerous automatic operations homogenize the information (author’s name, research body, department…), thus proving the quality of the bibliometric analyses. Now, Archimer enables, among others, the automatic calculation of several indicators defined by Ifremer and the different ministries in charge in the framework of its four-year contract. It also offers various criteria aimed at analysing its document production (eg. distribution of the value of the journals’ impact factors, evolution of the number of quotations in other publications, presentation of international collaborations…). As a consequence, the centralisation of Ifremer’s document production in Archimer will replace a number of different systems currently used by its research units to carry out such tasks. This should therefore result in an increase in Ifremer’s productivity as well as in a greater reliability of the archived documents.
En complément de ses objectifs de diffusion et de conservation, Archimer, l’archive institutionnelle de l’Ifremer, offre un ensemble d’outils bibliométriques. Dès l'enregistrement, de nombreux automatismes homogénéisent les informations (noms d'auteurs, organismes, affiliation interne...), gage de qualité des analyses bibliométriques. Archimer permet le calcul automatique de plusieurs indicateurs définis entre l'Ifremer et ses Ministères de Tutelles dans le cadre de son contrat quadriennal. Il offre également des éléments d’analyses de sa production documentaire (ex : répartition de la valeur des facteurs d’impacts des revues, évolution du nombre de citations des publications, présentation des collaborations internationales…). La centralisation de cette production documentaire dans Archimer permettra ainsi l’abandon d’une multitude de systèmes actuellement utilisés par les différentes unités de recherche pour assurer ces fonctions. C’est donc un gain de productivité autant que de fiabilité qui est attendu.

Résumé : Cooperation between the social and natural sciences has become essential in order to encompass all the dimensions of coastal zone management. Socio-economic approaches are increasingly recommended to complement integrated assessment in support of these initiatives. A systematic review of the academic literature was carried out in order to analyze the main types of socio-economic assessments used to inform the coastal zone management process as well as their effectiveness. A corpus of 1682 articles published between 1992 and 2011 was identified by means of the representative coverage approach, from which 170 were selected by applying inclusion/exclusion criteria and then classified using a content analysis methodology. The percentage of articles that mention the use of socio-economic assessment in support of coastal zone management initiatives is increasing but remains relatively low. The review examines the links between the issues addressed by integrated assessments and the chosen analytical frameworks as well as the various economic assessment methods which are used in the successive steps of the coastal zone management process. The results show that i) analytical frameworks such as 'risk and vulnerability', 'DPSIR', 'valuation', 'ecosystem services' and 'preferences' are likely to lead to effective integration of social sciences in coastal zone management research while 'integration', 'sustainability' and 'participation' remain difficult to operationalize, ii) risk assessments are insufficiently implemented in developing countries, and iii) indicator systems in support of multi-criteria analyses could be used during more stages of the coastal zone management process. Finally, it is suggested that improved collaboration between science and management would require that scientists currently involved in coastal zone management processes further educate themselves in integrated assessment approaches and participatory methodologies.

Résumé : Tahiti’s pearl farming industry plays a major socio-economic role in French Polynesia. In an increasingly competitive market where the production of high quality pearls becomes essential, research can help secure and ensure sustainable production. In that context, Ifremer, in close collaboration with the “direction des resources marines” (French Polynesian government agency) has developed research projects on the “sustainable development of pearl farming”. This program is organized along 3 axes: (1) understanding the animal physiology and initiating a genetically selective breeding program of donor oysters; (2) understanding pearl oyster larvae dispersal and recruitment; (3) understanding the molecular mechanisms underlying biomineralization processes during shell and pearl formation. It is in this frame that we have developed a highthroughput Expressed Sequence Tags pyrosequencing program on the calcifying mantle, combined with proteomic analyses of the shell and pearl. We analyzed 276738 EST sequences, leading to the constitution of a P. margaritifera mantle transcripts catalogue of 82 sequences potentially involved in biomineralization. Our results provided direct evidence that our ESTs data set covers a large number of the matrix proteins of P. margaritifera. In addition, our proteomic analysis enabled us to retrieve, in silico, all the sequences from P. margaritifera involved in the biomineralization process already published on databases. Integration of these two methods allowed, for the first time, the global composition of calcifying tissue and calcified structures to be examined in tandem.

The objective of this paper is to present an approach for experimenting territorial prospective analysis based on spatial modelling. This approach is carried out in the framework of the DESCARTES project which aims at developing a spatial simulation tool to support the design and analysis of different scenarios for land-use allocation in Reunion Island in terms of environmental services. The spatial modelling tool is composed of two complementary applications: (i) the Ocelet modelling language and its land dynamics simulation environment, and (ii) the Margouill@ platform. The first demonstrator, a model of farm land consumption by urbanization, was developed and presented during workshops in order to test the role of the spatial simulation tool in support of a collaborative innovation process among stakeholders, and to foster new research on social learning, spatial simulation of environmental services, and scale change issues.
L'objectif de cet article est de présenter une démarche de construction d'un exercice de prospective territoriale basé sur un outil de modélisation spatiale. Cette démarche est mise en œuvre dans le cadre du projet ANR DESCARTES dont l'objectif est de construire un outil de simulation cartographique pour analyser différents scénarios d'affectation de l'usage des sols à l'Ile de La Réunion, en termes de services environnementaux. La plateforme de simulation cartographique est composée de deux applications complémentaires (i) le langage de modélisation Ocelet et son environnement de simulation de paysages dynamiques, et (ii) la plateforme Margouill@. Le développement puis la présentation, en atelier, d'un premier démonstrateur sur la consommation des terres agricoles par l'urbanisation a permis de tester l'outil cartographique comme support d'un processus d'innovation collective entre les parties prenantes, et d'ouvrir de nouveaux champs de recherche sur l'analyse de la démarche par les apprentissages, la spatialisation et la simulation prospective des services écosystémiques, et la prise en compte du changement d'échelle.
