Organic carbon dynamics in clay soils: impact of management practices on microorganism structure and abundance under semi-arid conditions
<p>Proper management of soil organic matter in arid and semi-arid regions improves organic carbon storage in the soil, helps in compact soil degradation, mitigates climate change impacts, and preserves ecosystem functionality and sustainability food security. This study aims to provide a better insight into the biogeochemical processes that drive the organic carbon dynamics of saline clay soil in a semi-arid area. The study is not intended to be exhaustive but contributes to analyzing the relationship between bacterial microflora, physicochemical properties, and organic carbon dynamics as a function of different soil management modes. The monitoring was carried out on three different plots located at the National Institute of Agronomic Research of Algeria. A physicochemical characterization of the soils was performed. A metagenomic study was also conducted to identify bacterial biodiversity using PCR-amplified DNA sequencing. The study results show that the control plot has the highest average organic carbon stock value at 47 Mg ha-1. This was followed by the amended plot and the conventional plot, respectively, with 43 Mg ha-1 and 38 Mg ha-1. In the context of this study, organic carbon dynamics would appear to depend on the interaction of several biotic and abiotic factors. Soil management methods would impact the density and diversity of bacterial microflora. This, in turn, affects the soil's physicochemical properties and, more specifically, organic carbon dynamics and storage.</p>

Semi-arid African savanna habitat suitability for two Vachellia species
<p><span>The habitat suitability of <em>Vachellia</em> <em>stuhlmannii</em> and <em>Vachellia</em> <em>tortilis</em> was assessed using Maximum Entropy model. Location data was collected and nineteen bioclimatic variables data for 1950 to 2000 downloaded from the WorldClim database. Soils were analyzed to investigate their influence on habitat suitability of the two species. MaxEnt effectively predicted current habitat suitability with an average test Area Under Curve value of 0.936 for <em>V. stuhlmannii</em> and 0.689 for <em>V. tortilis</em>. Key influential variables were BIO-1 (Annual mean temperature) with 71.7% highest gain for <em>V. stuhlmannii</em> and BIO-17 (Precipitation of driest quarter) with 65.3% highest gain for <em>V. tortilis</em>. However, BIO-14 (Precipitation of driest month) exhibited limited influence in predicting habitat suitability for both species.<em> V. stuhlmannii</em> occupies twenty-nine hectares and <em>V. tortilis</em> covers 102 hectares. Both species predominantly occur on Prismacutanic/pedocutanic B-horizons. <em>V. tortilis</em> also thrive on Glenrosa and Mispah soils, which are crucial for diverse plant and animal life. These findings have practical implications for conservation efforts aimed at protecting both species. Identifying suitable habitats and preserving soil types is crucial as soil affects microclimate conditions and influences moisture retention. Overall, this study provides insights for the conservation of <em>V. stuhlmannii </em>and<em> V. tortilis</em> in the semi-arid African savanna.</span></p>
