[tel-00831619] Dynamiques territoriales et revendications identitaires des Amérindiens wayãpi et teko de la commune de Camopi (Guyane française).
Oct 19, 2020 | 13:00 pmLes territoires amérindiens couvrent de vastes étendues de forêts tropicales et possèdent une forte valeur sociale et environnementale. Soumis à des contraintes et opportunités variées, ils sont de nos jours le siège de nombreuses transformations territoriales. Ces transformations sont complexes et multiformes. Elles impliquent l'adoption de nouveaux modes de production et de consommation, le réajustement des formes d'organisation sociale et des dynamiques de réaffirmation identitaire et territoriale. Or les liens entre tous ces processus sont encore mal compris, et rendent délicate la compréhension des dynamiques d'adaptation des systèmes amérindiens de gestion des ressources communes. Cette thèse s'intéresse particulièrement aux dynamiques territoriales des Amérindiens wayãpi et teko de la commune de Camopi en Guyane française. Elle intègre des données sur l'occupation du sol obtenues par télédétection, des données socio-économiques et productives à l'échelle des ménages et des données qualitatives sur les processus identitaires, les réseaux de parenté, les politiques de conservation[…]

[hal-01529019] Advocacy coalitions and protected areas creation process: Case study in the Amazon
Oct 14, 2020 | 05:44 amProtected areas are the cornerstones of conservation policies worldwide. However, only few researches are led to analyse the way they emerge, except for criticising top-down governmental choices. Yet, the historical approach and strategic analysis of public policy building over the long term allows a better understanding of the stakes of action capacity of these policies. We therefore mobilize the advocacy coalition framework to show that protected areas creation is always due to coalitions of actors who belong to different professional fields and act at different scales but nevertheless share common stakes. On the basis of a comparative study in French and Brazilian Amazon, we show that if all coalitions for protected areas share a common objective of limited deforestation, they are still very different according to the type of conservation they promote (strict biodiversity conservation, population-based conservation or sustainable forest management). We also show that the ability of the coalitions[…]

[hal-01254935] Revision of vernacular names for the freshwater fish of French Guiana
Oct 14, 2020 | 05:41 amThe fish fauna of French Guiana is one of the best described in the geographical area covering the Guiana Shield. Paradoxically, however, there is no summary document validated by ethnologists and specialized linguists that links the scientific names of the fish of this area to their vernacular names from the different language groups. In this paper, we compile the presently existing data on species and vernacular names collected over several decades in Creole, Amerindian (Kali’na, Palikur, Wayana, Wayãpi and Teko), Nenges or Maroons (Boni, Ndjuka and Sranan Tongo) languages as well as French and/or specialist aquarium terms and Brazilian Portuguese. Of the 416 fish species found in French Guiana, we can assign a common name to 85% of them by considering all these languages as a group. These common names can be more or less generic, covering a greater or lesser number of species that are similar or very close[…]

[hal-01761584] iDNA screening: Disease vectors as vertebrate samplers
Oct 12, 2020 | 18:43 pmIn the current context of global change and human-induced biodiversity decline, there is an urgent need for developing sampling approaches able to accurately describe the state of biodiversity. Traditional surveys of vertebrate fauna involve time-consuming and skill-demanding field methods. Recently, the use of DNA derived from invertebrate parasites (leeches and blowflies) was suggested as a new tool for vertebrate diversity assessment. Bloodmeal analyses of arthropod disease vectors have long been performed to describe their feeding behaviour, for epidemiological purposes. On the other hand, this existing expertise has not yet been applied to investigate vertebrate fauna per se. Here, we evaluate the usefulness of hematophagous dipterans as vertebrate samplers. Blood-fed sand flies and mosquitoes were collected in Amazonian forest sites and analysed using high-throughput sequencing of short mitochondrial markers. Bloodmeal identifications highlighted contrasting ecological features and feeding behaviour among dipteran species, which allowed unveiling arboreal and terrestrial mammals of various body[…]

[hal-02895247] Managing and sharing multidisciplinary information in human-environment observatories: feedbacks and recommendations from the French DRIIHM network
Oct 12, 2020 | 12:54 pmThe LabEx DRIIHM is a research network that gathers together 13 Human-Environment Observatories (OHM) focused on anthropogenically modified socio-ecosystems in France and worldwide. Within the open science context, a Research Data Infrastructure (RDI) was implemented brick by brick to describe, visualize, and disseminate multidisciplinary long-tail datasets produced by the DRIIHM community. The RDI contains both tools and standards at the network scale, and specific tools at the individual observatory scale. This paper describes the building blocks of the RDI and analyses its strengths and challenges on the basis of engineer feedback and user surveys. Recommendations for improving the RDI, better measuring its effectiveness, and enhancing open science awareness, have been formalized for the SO-DRIIHM project that will start in 2020. Cross-disciplinary approaches using DataViz tools have emerged already, and these enrich the way in which scientific information is disseminated, and could raise new scientific issues.

[tel-01520101] Captures estuariennes
Oct 5, 2020 | 11:12 amLa pêche repose sur des formes variées d'appropriation sociale des milieux aquatiques. Cette thèse s'attache à les définir dans le contexte particulier du bas Oyapock, estuaire d'un fleuve amazonien marquant la frontière entre la Guyane (France) et l'Etat d'Amapá (Brésil). Cet estuaire présente une importante diversité d'écosystèmes aquatiques (rivières, fleuves, forêts galeries, marais, mangrove et mer) et d'espèces végétales et animales qui les composent (près de 200 espèces y sont pêchées). La population du bas Oyapock forme un creuset culturel réunissant principalement Amérindiens, Créoles et Brésiliens, implantés dans deux villes et 40 villages. Par ailleurs, la présence d'un parc national sur le littoral brésilien et de trois territoires amérindiens implique des réglementations de l'accès aux ressources diverses. Dans ce contexte riche en diversité écologique et culturelle où émergent des conflits d'usage sur les territoires de pêche, cette thèse propose une lecture des dynamiques d'appropriation des ressources aquatiques par les pêcheurs.[…]
