Data from: Prominent intra-specific genetic divergence within Anopheles gambiae sibling species triggered by habitat discontinuities across a riverine landscapeBeniamino Caputo, Davis Nwakanma, Francesco Paolo Caputo, Musa Jawara, Cheryll Oriero, Majidah Adiamoh, Ibrahima Dia, Lassana Konate, Vincenzo Petrarca, Joao Pinto, David J. Conway, Alessandra Della Torre, E. C. Oriero & M. Hamid-Adiamoh
The Anopheles gambiae complex of mosquitoes includes malaria vectors at different stages of speciation, whose study enables a better understanding of how adaptation to divergent environmental conditions leads to evolution of reproductive isolation. We investigated the population genetic structure of closely-related sympatric taxa that have recently been proposed as separate species (An. coluzzii and An. gambiae), sampled from diverse habitats along the Gambia River in West Africa. We characterised putatively neutral microsatellite loci as well...
Nowcasting (weather forecasting predictions from zero to several hours) has enormous value and potential in Africa, where populations and economic activity are highly vulnerable to rapidly changing weather conditions. Timely issuing of warnings, a few hours before an event, can enable the public and decision-makers to take action. Rainfall radar estimates are not widely available in Africa, nor likely to be in the coming years, and numerical weather prediction (NWP) currently has low skill over...
A sense of fairness plays a critical role in supporting human cooperation. Adult norms of fair resource sharing vary widely across societies, suggesting that culture shapes the acquisition of fairness behaviour during childhood. Here we examine how fairness behaviour develops in children from seven diverse societies, testing children from 4 to 15 years of age (n = 866 pairs) in a standardized resource decision task. We measured two key aspects of fairness decisions: disadvantageous inequity...
Macrolophus pygmaeus Rambur (Hemiptera: Miridae) is a generalist predatory mirid widely used in augmentative biological control of various insect pests in greenhouse tomato production in Europe, including the invasive tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae). However, its biocontrol efficacy often relies on the presence of alternative prey. The present study aimed at evaluating the effect of various prey foods (Ephestia kuehniella eggs, Bemisia tabaci nymphs, Tuta absoluta eggs and Macrosiphum euphorbiae nymphs) on some...
Background: Chloroplast genomes provide insufficient phylogenetic information to distinguish between closely related sugarcane cultivars, due to the recent origin of many cultivars and the conserved sequence of the chloroplast. In comparison, the mitochondrial genome of plants is much larger and more plastic and could contain increased phylogenetic signals. We assembled a consensus reference mitochondrion with Illumina TruSeq synthetic long reads and ONT MinION long reads. Based on this assembly we also analyzed the mitochondrial transcriptomes...

Sero-surveillance can monitor and project disease burden and risk. However, SARS-CoV-2 antibody test results can produce false positive results, limiting their efficacy as a sero-surveillance tool to estimate population-level SARS-CoV-2 exposure. False positive SARS-CoV-2 antibody results have been associated with malaria exposure, and understanding this association is essential to interpret sero-surveillance results from malaria-endemic countries. Here, pre-pandemic samples from eight malaria endemic and non-endemic countries and four continents were tested by ELISA to measure SARS-CoV-2...
Data from: Validity of bioelectrical impedance analysis in predicting total body water and adiposity among Senegalese school-aged childrenNicole Idohou-Dossou, Mégné Nde, Salimata Wade, Adama Diouf, Mbeugué Thiam & Ousmane Diongue
Introduction: Childhood obesity is currently a serious public health challenge in developing countries. Therefore, an accurate assessment of adiposity is required. The objective of this study was to validate BIA prediction equations for the assessment of total body water and adiposity or percentage of body fat for the first time in Senegalese school-aged children. Methods: One-hundred-fifty-one (151) pupils who were 8-11 years old were randomly selected from four public schools in Dakar. The body composition...
Data from: Deciphering host-parasitoid interactions and parasitism rates of crop pests using DNA metabarcodingAhmadou Sow, Thierry Brévault, Laure Benoit, Marie-Pierre Chapuis, Maxime Galan, Armelle Coeur D'Acier, Gérard Delvare, Mbacké Sembène & Julien Haran
An accurate estimation of parasitism rate and diversity in insect pests is a prerequisite to explore processes leading to efficient natural biocontrol. While traditional methods, such as rearing, is often limited to taxonomic identification, mortality and intensive work. The advent of high-throughput sequencing (HTS) techniques, such as DNA metabarcoding, is increasingly seen as a reliable and powerful alternative approach. However, benefits from such an approach to estimate parasitism rate and diversity in an agricultural context...
Adequate vitamin A liver stores estimated by the Modified-Relative Dose Response test are positively associated with breastfeeding but not vitamin A supplementation in Senegalese urban children 9-23 months old: a comparative cross-sectional studyMane Hélène FAYE, Marie-Madeleine A Diémé, Nicole Idohou-Dossou, Abdou Badiane, Adama Diouf, Ndeye Magatte Ndiaye Ndome & Sherry A Tanumihardjo
Vitamin A supplementation (VAS) in 6-59 month old children is recommended but its sustainability is currently questioned. In Senegal, data suggest that VAS should be maintained, but geographic and age-related specificities need to be addressed by gathering more evidence on the impact of this program. The objective of this comparative cross-sectional study, conducted in urban settings of Dakar, was to evaluate the effectiveness of VAS on vitamin A liver stores (VALS) among 9-23 month old...
Plasmodium falciparum genomic surveillance reveals spatial and temporal trends, association of genetic and physical distance, and household clusteringMouhamad Sy, Awa Deme, Joshua Warren, Rachel Daniels, Baba Dieye, Pape Ibrahima Ndiaye, Younous Diedhiou, Amadou Moctar Mbaye, Sarah Volkman, Daniel Hartl, Dyann Wirth, Daouda Ndiaye & Amy Bei
Molecular epidemiology using genomic data can help identify relationships between malaria parasite population structure, malaria transmission intensity, and ultimately help generate actionable data to assess the effectiveness of malaria control strategies. Genomic data, coupled with geographic information systems data, can further identify clusters or hotspots of malaria transmission, parasite genetic and spatial connectivity, and parasite movement by human or mosquito mobility over time and space. In this study, we performed longitudinal genomic surveillance in a...
Décoloniser les politiques du désastre climatique dans l’estuaire du Sénégal : des pratiques adaptatives entre « passé finissant » et « futur proche »Cheikh Ba & Yvan Renou
Dans une région frappée par une accumulation des risques hydrologiques face auxquels les « politiques du désastre » ne sont pas parvenues à spécifier des actions adaptatives pertinentes, une décolonisation des imaginaires environnementaux semble nécessaire. Afin de renseigner concrètement comment pourrait s’opérationnaliser une transition « soutenable » dans l’estuairedu Sénégal, nous proposons de déplier la « scène urbaine» de Saint-Louis dans une perspective multi-échelles. Fondant notre approche sur une écologie politique des savoirs, nous procédons...
Effectiveness of seasonal malaria chemoprevention administered in a mass campaign in the Kedougou region of Senegal in 2016: a Case-control studyIsaac Akhenaton Manga, Fassiatou Tairou, Amadou Seck, Ekoue Kouevidjin, Mamadou Sarifou Ba, Omar Gaye, Babacar Faye & Jean Louis Abdourahim Ndiaye
Context Seasonal malaria chemoprevention (SMC) with Sulfadoxine-Pyrimethamine plus Amodiaquine (SPAQ) is a malaria prevention strategy recommended since 2012 by the World Health Organization (WHO) for children under 5 years of age. In Senegal, the scaling up of the SMC has started since 2013 in the south-eastern regions of the country with an extension of the target to 10 years old children. The scaling up of SMC requires a regular evaluation of the strategy as recommended...
