A pot experiment was conducted in a completely randomized design with three replications to reclaim artificially induced salinity-related attributes in soil (7.0 dS m⁻¹) using various cyanobacteria strains. For this purpose, six treatments were used, control, Oscillatory-MMF-1 (<em>Oscillatoria princeps)</em>, Leptolyngbaya-MMF-2 (<em>Lyngbya mucicola)</em>, Leptolyngbaya-MMF-3 (<em>Lyngbya Phormidium)</em>, Gloeobacter-MMF-4 (<em>Gloeocapsa)</em> and Microcoleus-MMF-5 (<em>Cryophilus)</em>. The salinity-induced soil was treated with the appropriate treatments before the transplantation of rice seedlings to each pot. The rice crop was grown for 100 days and monitored for growth attributes. Similarly, the soil was monitored for physicochemical properties. The experimental results revealed a significant reduction in soil pH from 8.32 to 7.20, EC from 7 to 5.2 dS m⁻¹, Na⁺ from 2552 to 1146 mg kg⁻¹, soil bulk density from 1.37 to 1.31 g cm⁻³ by the cyanobacterial strain MMF-4 Gloeobacter (<em>Gloeocapsa</em>), showing 13.5%, 25.7%, 55% and 4.38% decrease respectively. Whereas the cyanobacterial strain (Gloeobacter) significantly enhanced the concentration level of Ca⁺⁺ (944 mg kg⁻¹), Mg⁺⁺ (358 mg kg⁻¹) and increased the porosity up to 50.69% and saturation percentage (35.50) in the induced saline soils. It can be concluded from the findings that all the strains of cyanobacteria reclaimed soil salinity by reducing soil EC, pH, SAR, and soil bulk density and increased Ca⁺⁺, Mg⁺⁺, porosity, and saturation percentage (SP) in the saline soil. However, the best performance was recorded for MMF-4 (Gloeobacter) and MMF-5 (Microcoleus) strains and recommended for further research.</p></div>","PeriodicalId":7048,"journal":{"name":"生态学报","volume":"43 6","pages":"Pages 1074-1079"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71726193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focused on assessing LCLU changes in the Greater Gaborone area of South Eastern Botswana between 1988 and 2022. The study employed remote sensing (RS) and geographic information systems (GIS) tools for analyzing LCLU changes in the study area during the study period. Landsat images of 1988 and 2002 and Sentinel-2A images of 2022 were used to detect LCLU changes. Image classification was done using a Supervised classification approach based on a Maximum Likelihood Classifier. Six LCLU types such as water body, trees dominated, cropland, shrubland, bare land, and built-up, were identified in the area. Post Classification Comparison (PCC) approach was used to detect LCLU change during the study period. Shrubland class was found to be the dominant LCLU type in the study area. A significant gain was observed in the built-up class (75.12 km²), while significant losses were observed in shrubland (24.16 km²) and trees dominated (33.32 km²) classes in the entire study period. Given the rapid increase in built-up areas, this recommends that land managers and policymakers should invest in implementing sustainable land management interventions to prevent undesirable LCLU changes.</p></div>","PeriodicalId":7048,"journal":{"name":"生态学报","volume":"43 6","pages":"Pages 1080-1089"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71726055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 16S-metagenomic analysis was conducted to investigate the bacterial community of the samples by amplifying the V3-V4 region.

Beta-diversity analysis showed that the B fertilizer did not highly change the bacterial community of indigenous rhizosphere bacteria, whereas the A2 fertilizer did. The endophytes themselves did not also greatly affect the original rhizosphere bacteria because they may enter the plant tissue and release the metabolites inside the plant host. The NGS data showed that the genus <em>Aquicella</em> was the most abundant in the rhizosphere treated with B and A1. <em>Aquicella</em> was discovered to boost plant resilience to contaminants by enhancing plant nutrition availability and encouraging plant root growth. Interestingly, <em>Acidobacteria</em> and <em>Gemmatimonadetes</em> decreased their population in the treatments of A2 or B.
