| Establishment and functioning of the savanna marshes of the Lopé National Park in Gabon since the termination of the African humid period and the arrival of humans 2500 years ago BREMOND L., OSLISLY R., SEBAG D., BENTALEB I., FAVIER C., HENGA-BOTSIKABOBE K., MVOUBOU M., NGOMANDA A., DE SAULIEU G. Abstract: Holocene palaeoecological studies in tropical Africa are rare because most lakes either dried out at the termination of the African Humid Period or have since filled up. However, tropical sedge marshes can be an alternative to perform long-term ecological studies. The Lopé National Park (LNP) in Gabon is a mosaic of forest and savanna enclosed in the equatorial forest, where open areas facilitated the development of peat marshes accumulating several-meter-thick sediment. In order to reconstruct the historical dynamic in these marshes through a local and regional point of view, we compared sedimentological, continuous X-ray fluorescence, and stable isotopic analyses on sediment cores from six herbaceous marshes in the LNP. A reliable chronological frame was based on 50 14C dates, over the last 2500 years in most sites, and reaching 9,000 years in one marsh. We show that the origin of these marshes is a major hydrological change, 3450 and 2300 years ago, that affected the entire region, almost concomitantly with the diffusion of Iron Age population. The sedimentation within marshes ishomogenous with low intra-site variability. In contrast, high inter-sites variability evidences that the functioning of the marsh itself exerts a much more significant influence than in lakes. However, a regional event is recorded between 1400 and 800 years ago, concurrently with an archaeological trace hiatus throughout the forest hinterland of West Central Africa.Introduction Source title: The holocene DOI: 10.1177/09596836211003230 Link: https://dumas.ccsd.cnrs.fr/PALOC/hal-03197824v1 Correspondence Address: [No correspondence address] Language of Original Document: English Document Type: Article Keywords: Gabon; Tropical marshes; Sediments; Multi-proxy analysis; XRF; Paleoenvironment Protected area: La Lopé, Gabon Main topic: Environment Subtopic: Geology/Pedology ; Forests ; Savannas | 2021 |
| Larval breeding sites of the mosquitoAedes aegyptiin forest anddomestic habitats in Africa and the potential association withoviposition evolution XIA S., DWECK H., LUTOMIAH J., SANG R., MCBRIDE C., ROSE N., AYALA D., POWELL J. Abstract: Adaptations to anthropogenic domestic habitats contribute to the success of mosquito Aedes aegyptias a major global vectorof several arboviral diseases. The species inhabited African forests before expanding into domestic habitats and spreading tothe rest of the world. Despite a well-studied evolutionary history, how this species initially moved into human settlements inAfrica remains unclear. During this initial habitat transition,Ae. aegyptiswitched from using natural containers like tree holesas larval breeding sites to using artificial containers like clay pots. Little is known about how these natural versus artificialcontainers differ in their environments, or whetherAe. aegyptiin forest versus domestic habitats evolved any correspondingincipient behavioral divergence, such as in oviposition. To address these gaps, we first characterized physical characteristics,larval density, microbial density, bacterial composition, and volatile profiles of natural versus artificial containers used asmosquito larval breeding sites. We focused on two localities in Africa, La Lop ´e, Gabon and Rabai, Kenya. In both localities,our data showed that the two habitat-specific container types had significantly different characteristics. We then examinedwhether such containers differed in their attractiveness for oviposition, a key behavior affecting larval distribution. ForestAe.aegyptireadily accepted artificial containers in our field experiments, and laboratory choice experiments did not find distinctoviposition preference between forest and villageAe. aegypticolonies. These results suggested that AfricanAe. aegyptiwerelikely generalists in their oviposition site choice. This flexibility to accept different containers might play a vital role during theinitial domestication ofAe. aegypti, allowing the mosquitoes to use human-stored water as fallback breeding sites during dryseasons. Although ovipositional changes were not present initially, after longer domestic habitat breeding, the mosquitoes didevolve divergence oviposition preference, as suggested by previous comparisons of AfricanAe. aegyptiand human-specializednon-AfricanAe. aegypti.

| Minimal effect of prescribed burning on fire spread rate and intensity in savanna ecosystems MOUSTAKAS A., DAVLIAS O. Abstract: "Fire has been an integral part of the Earth for millennia. Several recent wildfires have exhibited an unprecedented spatial and temporal extent and their control is beyond national firefighting capabilities. Prescribed or controlled burning treatments are debated as a potential measure for ameliorating the spread and intensity of wildfires. Machine learning analysis using random forests was performed in a spatio-temporal data set comprising a large number of savanna fires across 22 years. Results indicate that fire return interval was not an important predictor of fire spread rate or fire intensity, having a feature importance of 3.5%, among eight other predictor variables. Manipulating burn seasonality showed a feature importance of 6% or less regarding fire spread rate or fire intensity. While manipulated fire return interval and seasonality moderated both fire spread rate and intensity, their overall effects were low in comparison with meteorological (hydrological and climatic) variables. The variables with the highest feature importance regarding fire spread rate resulted in fuel moisture with 21%, relative humidity with 15%, wind speed with 14%, and last years rainfall with 14%. The variables with the highest feature importance regarding fire intensity included fuel load with 21.5%, fuel moisture with 16.5%, relative humidity with 12.5%, air temperature with 12.5%, and rainfall with 12.5%. Predicting fire spread rate and intensity has been a poor endeavour thus far and we show that more data of the variables already monitored would not result in higher predictive accuracy."

| Retrieval of Tropical Forest Height and Above-Ground Biomass Using Airborne P- and L-Band SAR Tomography LIU X., ZHANG L., YANG X., LIAO M., LI W. Abstract: Synthetic aperture radar tomography (TomoSAR) at different radar wavelength can be used to measure different structural elements of forests. In this letter, we compared the airborne P- and L-band synthetic aperture radar (SAR) tomograms and TomoSAR-measured canopy height model (CHM) and above-ground biomass (AGB) over a tropical forest in Lopé, Gabon. The SAR data sets were acquired by German Aerospace Center (DLR)'s F-SAR system during the AfriSAR2016 campaign. First, the Weighted covariance fitting-based Iterative Spectral Estimator (WISE) was applied to obtain tomograms. CHM was then retrieved based on the canopy phase center derived from the tomograms. Finally, AGB was estimated via an empirical logarithmic model developed from field measurements and the tomographic backscatter power of vegetation layers between 40 and 50 m above ground. Compared with the classical approaches of Capon and Wavelet-based Compressed Sensing, the WISE method can achieve better resolution with higher computational efficiency and reduce the ambiguity level of L-band tomograms successfully. The experimental results also show that there is no substantial difference between P- and L-band TomoCHM, while P-band tomographic intensity is more sensitive than the L-band for the inversion of tropical forest AGB at a resolution of 50 m x 50 m.

| Benefits and pitfalls of captive conservation genetic management: Evaluating diversity in scimitar-horned oryx to support reintroduction planning OGDEN R., CHUVEN J., GILBERT T., HOSKING C., GHARBI K., CRAIG M., AL DHABERI S.S., SENN H. Abstract: "The reintroduction of the scimitar-horned oryx to Chad is a multi-disciplinary endeavour, planned and implemented over the past decade, utilizing a wide range of conservation science applications to maximise the chances of long-term population sustainability. The principle of incorporating genetic diversity information into founder selection for species reintroductions is widely recognized; however, in practice, a full assessment of available ex-situ genetic variation is rarely attempted prior to identifying individuals for release. In this study we present the results of over ten years of research analyzing and interpreting the genetic diversity present in the key source populations for the Chad scimitar-horned oryx reintroduction. Three empirical genetic datasets (mitochondrial DNA sequence, nuclear DNA microsatellite and SNP markers) comprising over 500 individuals sampled from public and private institutions were analysed, accompanied by simulation studies to address applied questions relating to management of the reintroduction. The results strongly demonstrate the importance of conservation genetic analysis in ensuring that founders represent the greatest breadth of evolutionary diversity available. The inclusion of both intensively and lightly managed collections allowed us to bridge the gap between studbook and group managed populations, enabling the inclusion of individuals from populations that lack historic data on their origins, but which may hold unique diversity of significant conservation value. Importantly, however, our study also reveals the potential risks of applying standard population genetic approaches to multiple captive populations, for which small founder sizes are likely to strongly bias results, with potentially serious consequences for the genetic management of conservation breeding programmes."

| Combining optical and radar satellite image time series to map natural vegetation: savannas as an example LOPES M., FRISON P.-L., DURANT S.M., SCHULTE TO BÜHNE H., IPAVEC A., LAPEYRE V., PETTORELLI N. Abstract: "Up-to-date land cover maps are important for biodiversity monitoring as they are central to habitat and ecosystem distribution assessments. Satellite remote sensing is a key technology for generating these maps. Until recently, land cover mapping has been limited to static approaches, which have primarily led to the production of either global maps at coarse spatial resolutions or geographically restricted maps at high spatial resolutions. The recent availability of optical (Sentinel-2) and radar (Sentinel-1) satellite image time series (SITS) which provide access to high spatial and very high temporal resolutions, is a game changer, offering opportunities to map land cover using both temporal and spatial information. These data moreover open interesting perspectives for land cover mapping based on data combination approach. However, the usefulness of combining dense time series (more than 30 images per year) and data combination approaches to map natural vegetation has so far not been assessed. To address this gap, this contribution tests the idea that the combined consideration of optical and radar data combination and time series analyses can significantly improve natural vegetation mapping in the Pendjari National Park, a Sahelian savanna protected area in Benin. Results highlight that the combination of Sentinel-1 and Sentinel-2 SITS performs as well as Sentinel-2 SITS alone in terms of classification accuracy. Land cover maps are however qualitatively better when considering the data combination approach. Our results also clearly show that the use of dense/hypertemporal optical time series significantly improves classification outcomes compared to using multitemporal only a few images per year) or monotemporal data. Altogether, this work thus demonstrates the ability of dense SITS to improve discrimination of natural vegetation types using information on their phenology, leading to more detailed and more reliable maps for environmental management.
