[hal-02895247] Managing and sharing multidisciplinary information in human-environment observatories: feedbacks and recommendations from the French DRIIHM network
Jan 17, 2022 | 14:38 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.

[hal-01254935] Revision of vernacular names for the freshwater fish of French Guiana
Jan 11, 2022 | 17:56 pmThe 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-01833403] Palikur traditional roundwood construction in eastern French Guiana: ethnobotanical and cultural perspectives
Jan 11, 2022 | 17:56 pmPalikur Amerindians live in the eastern part of French Guiana which is undergoing deep-seated changes due to the geographical and economic opening of the region. So far, Palikur’s traditional ecological knowledge is poorly documented, apart from medicinal plants. The aim of this study was to document ethnobotanical practices related to traditional construction in the region.

[hal-01761584] iDNA screening: Disease vectors as vertebrate samplers
Nov 17, 2021 | 12:31 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-03422437] Human-Environment Observatory (OHM) Oyapock
Nov 16, 2021 | 05:27 amThe study area stretches along both banks of the Oyapock river, a natural border between French Guiana and Brazil. The OHM is located entirely within the tropical rainforest, and includes the communities of Ouanary, Saint-Georges-del’Oyapock, Camopi on the French side, and the vast community of Oiapoque on the Brazilian side. Sparsely populated, this area is in the process of being opened up to the outside world with the recent opening of two roads that reach all the way to the river. The construction of this transborder river bridge should further accelerate these changes. The OHM aims to identify and monitor the key processes which will influence the human population and its environment, their interactions and their dynamics, after the construction of this bridge.

[tel-01764244] Biodiversité et maladies infectieuses: Impact des activités humaines sur le cycle de transmission des leishmanioses en Guyane
Nov 3, 2021 | 08:11 amSelon l’hypothèse de l'effet de dilution, les écosystèmes les plus riches en espèces seraient également les moins propices à la circulation des agents infectieux du fait de la présence d'hôtes non compétents constituant des impasses épidémiologiques. Dans cette thèse, nous explorons l’existence de ce phénomène sur le modèle des leishmanioses cutanées zoonotiques en Guyane. Des outils moléculaires basés sur l’utilisation des technologies de séquençage haut-débit ont été développés pour étudier le système épidémiologique. Ces outils ont ensuite été employés pour caractériser le cycle de transmission des leishmanioses dans des sites forestiers sujets à différents niveaux de perturbation d’origine humaine. Nos résultats semblent globalement congruents avec l’hypothèse de l’effet de dilution, et indiquent un risque infectieux plus élevé sur le site le plus perturbé. Toutefois, les différences observées entre les sites ne sont pas significatives et d’avantage de données seraient nécessaires pour tirer des conclusions générales.

[hal-01529019] Advocacy coalitions and protected areas creation process: Case study in the Amazon
Nov 3, 2021 | 08:05 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[…]
