[hal-02382056] Promote Open Science within the DRIIHM Interdisciplinary Research Facility on Human- Environment Interactions: Co-design of an e-infrastructure implementing the FAIR Principles
Jul 8, 2020 | 14:43 pmAs part of the international Open Science movement, this project deals with the structuration, sharing and opening of research data in the context of a network of thirteen CNRS-INEE observatories (OHMs): the Interdisciplinary Research Facility on Human-Environment Interactions supported by the ANR (LabEx DRIIHM 2012-2025). This network involves nearly 1000 scientists. Large amounts of heterogeneous data are produced or collected, covering research in Natural and Life Sciences, and Human and Social Sciences. Several initiatives have been carried out within the LabEx DRIIHM to increase visibility and data sharing to connect scientific teams that are not always linked, promote the re-use of data and potentially lead to the emergence of new research topics. A range of tools has been developed over the years: metadata geo-catalogs, web GIS platforms, photo libraries, HAL collections, etc. However, there are significant contrasts in the contribution to these tools and their use between OHMs, and two[…]

[hal-02373055] SO-DRIIHM - Impulser la science ouverte au sein du LabEx DRIIHM : Co-design d'une e-infrastructure intégrant les principes FAIR
Jul 8, 2020 | 14:43 pmDans le cadre du mouvement international de la science ouverte, ce projet traite de la structuration, du partage et de l’ouverture des données produites au sein d’un réseau de treize observatoires (OHMs) du CNRS-INEE : le Dispositif de Recherche Interdisciplinaire sur les Interactions Hommes-Milieux soutenu par l’ANR (LabEx DRIIHM 2012-2025). Il implique près de 1000 scientifiques. De grandes quantités de données hétérogènes sont produites ou collectées dans les domaines des Sciences de la Nature et du Vivant, et des Sciences Humaines et Sociales. Plusieurs initiatives ont été menées au sein du LabEx pour augmenter la visibilité et le partage des données, mettre en relation des équipes scientifiques, favoriser la ré-utilisation de données et potentiellement faire émerger de nouvelles recherches. Un panel d’outils a ainsi été mis en place au fil des années : géo-catalogues de métadonnées, web SIG, photothèque, collections HAL, etc. Cependant, il existe des contrastes importants dans l’alimentation[…]

[hal-02322991] SO-DRIIHM: promoting Open Science within the LabEx DRIIHM and improving its Research Data Infrastructure
Jul 8, 2020 | 14:43 pmThe "SO-DRIIHM" project has just obtained funding from the Flash Call "Open Science: research practices and open research data" proposed by the ANR in 2019. It is managed by a group of geomatics and IT engineers within the CNRS interdisciplinary network (LabEx DRIIHM) of 13 Human-environment observatories (OHMs). The objective of this project (May 2020 - April 2022) is to optimize the appropriation of the open science approach by the DRIIHM research community through: •the organisation of awareness campaigns showing the benefits of data sharing and openness; •the co-construction of a more ergonomic and interoperable e-infrastructure, integrating existing tools (metadata geocatalogues, web GIS, photo library, HAL collection, etc.) and accompanying researchers to find, share and (re)use data with the concrete and progressive implementation of the FAIR principles (Findable, Accessible, Interoperable, Reusable). The originality of this project lies in the bottom-up co-construction of the e-infrastructure, involving researchers from the early stages[…]

[hal-01350584] Variabilité de la capacité de sorption du glyphosate et diuron des fonds de fossés évaluée à l'aide de nouveaux indicateurs
Jul 2, 2020 | 19:24 pmLes réseaux de fossés jouent un rôle clé dans la gestion des flux hydriques et sédimentaires au sein des bassins versants agricoles ce qui leur confère une importance particulière dans le devenir des pesticides (Dollinger et al., 2015). En effet, bien que constituant des voies de dispersion, par la collecte et l’acheminement des flux de ruissellement ou de drainage potentiellement chargés en pesticides, les fossés ont été décrits comme des zones tampons efficaces pouvant limiter la pollution des masses d’eau (Dollinger et al., 2015; Needelman et al., 2007). Le pouvoir tampon des fossés vis-à-vis des pollutions par les pesticides résulte essentiellement de processus de sorption sur les différents matériaux des fonds de fossés (e.g., Stehle et al., 2011). La capacité de sorption de pesticides est d onc étroitement liée à l a nature et à l’abondance des différents matériaux constituant les fonds de f ossés tels que le sol, la[…]

[hal-01723198] Effets des principales essences de la grande muraille verte sénégalaise sur les taux d'azote minéral du sol et la biomasse microbienne
Jul 2, 2020 | 16:19 pmAn experiment was conducted over nine months in a field system in northern Senegal in order to determine the effects on soil nitrogen (N) cycling and the microbial biomass-C properties of five plant species proposed for the Senegalese Great Green Wall (GGW): Acacia senegal (L.) Willd., Acacia tortilis var. raddiana (Savi) Brenan, Balanites aegyptiaca (L.) Del., Boscia senegalensis (Pers.) Lam. ex Poir., and Sclerocarya birrea (A. Rich.) Hochst. Soil samples were collected to a depth of 0-10 cm, outside (control) and beneath tree canopies. Microbial biomass, inorganic N content and net mineralization of organic N were determined for the soil samples collected under trees, and compared to soils collected outside tree canopies. The results showed that concentrations of inorganic N and soil microbial biomass-C were generally higher under canopy cover and differed according to species. In May 2014 (end of the dry season), microbial biomass-C was higher under A. senegal[…]

[hal-01722639] Comparing genetic diversity of Sitophilus zeamais (Motchulsky) populations sampled in several agro-ecological areas between Central African Republic and Senegal
Jul 2, 2020 | 16:18 pmMaize is attacked by many post-harvest pests including Sitophilus spp and Prostephanus spp, which causes remarkable loss during storage. Approximately 30 to 40 % loss in the absence of treatment has been reported worldwide. This study compare genetically Central African and Senegalese populations of Sitophilus zeamais from various agroecological zones using 3 markers namely cytochrome b, cytochrome oxidase and nuclear 28S gene. S. zeamais samples were analyzed on both of two other sites 34 for the 28S gene; 68 for cytochrome b and 36 for the cytochrome oxydase. Results analyzed by AMOVA have shown high genetic variation outside population of each country (6.17 % with Cyt b; 21.45 % with 49.83 % and COI in the case of 28S) and low within subpopulations (-10.06 % for Cyt b, 9.36 % for the COI and-15.23 % for 28S). Majority haplotype is shared between the two populations for 28S and cytochrome b[…]

[hal-01723210] Identification morphométrique des populations de Tribolium castaneum Herbst (Coleoptera, Tenebrionidae) inféodées à trois céréales à Widou Thiengoli
May 25, 2020 | 16:28 pmRÉSUMÉ. Objectif : Tribolium castaneum, est un coléoptère qui a la capacité d'infester toutes les céréales et légumineuses entreposées. Sa capacité à dérouler son cycle de développement sur divers substrats alimentaires a suscité des réflexions sur son adaptabilité morphologique. Cette étude a pour objectif d'identifier la morphologie de T. castaneum à Widou sur différentes céréales. Méthodologie et résultats : Trois populations ont été définies en fonction de la céréale (maïs, mil ou riz) sur laquelle T. castaneum a déroulé son cycle de développement. Chacune des populations est constituée de 30 adultes mâles. Sur chaque adulte, 19 variables ont été mesurées. Les distances entre des yeux dorsalement et ventralement (Dyd, Dyv), la largeur du fémur_3 (lf3) et des élytres (lme) sont éliminées de l'analyse car ne présentant aucune variabilité entre les différents individus. Les 15 variables restantes sont utilisées pour des Analyses en Composante Principale. La taille est le premier facteur[…]

[hal-01723169] Identification of Tribolium castaneum (Herbst) haplotypes, the pest of stocked millet in Senegal
May 25, 2020 | 16:28 pmObjective: Millet is the staple food of millions of people living in the Sahelian zone and the tropical countries of West Africa. It occupies an important place in the Senegalese alimentation. The major damages to this cereal are caused by the beetle Tribolium castaneum Herbst (Tenebrionidae) whose adults give a repulsive smell of stored food and making them unusable. The objective of this study is to identify the different haplotypes of T. castaneum and their distribution in Senegal. Methodology and Results: To achieve this, a sampling was performed in seven (7) localities of Senegal belonging to four agro-ecological zones. The DNA of each individual was extracted and the cytochrome b was amplified with Qiagen protocol and then sequenced. The results showed the existence of nine (9) haplotypes in Senegal and the haplotype Hap_1 prevailed among them and was present in all sampled areas. Haplotypes Hap_4 of Mbam, Hap_3 of Diaroumé,[…]
