This study investigated the effective use of this material as a novel component in planting substrates to improve the physicochemical characteristics of arid sandstone soil in mining areas. The goal was to use this modified substrate for the restoration of vegetation, which at the same time would allow an effective utilization of coal gangue and its removal from mining areas. Using an L16 (4^3) orthogonal experimental design, systematically investigated the effects of three factors, i.e., coal gangue, a water-retaining agent, and bentonite, applied at various levels on soil nutrient characteristics and plant growth indicators in order to optimize the formula for the planting substrate. The addition of 1500 g of coal gangue significantly increased the contents of organic matter, total nitrogen, total phosphorus, total potassium, available nitrogen, and available potassium in the substrate (<em>p</em> &lt; 0.05). This enhancement promoted the growth of <em>Kochia prostrata</em>. With the addition of 0.4 % water-retaining agent, the available nitrogen content in the substrate increased significantly (<em>p</em> &lt; 0.05). However, conditions were more favorable for seed germination and plant survival when this agent was not added. Moreover, the addition of 4 % bentonite resulted in a significant increase in the height of <em>Kochia prostrata</em> (<em>p</em> &lt; 0.05). The comprehensive analysis using the orthogonal experimental model indicated that the optimal coal gangue to sandstone soil ratio for vegetation growth was 375:1125 g, with the water-retaining agent and bentonite added at mass fractions of 0.1 % and 2 %, respectively. This ratio significantly enhanced the nutritional composition of the planting substrate, promoting the germination and growth of <em>Kochia prostrata</em>.

The basking shark (<em>Cetorhinus maximus</em>), the second-largest fish species, faces significant conservation challenges due to overfishing, habitat degradation, and climate change, necessitating urgent research to address knowledge gaps in its spatial distribution and interactions with changing marine environments. This study employs various environmental variables and distribution data to construct a global species distribution model for basking sharks, predicting their distribution patterns under current and future climate scenarios. The results indicate that chlorophyll, sea surface temperature, silicate and mixed layer depth are the primary factors determining habitat suitability for basking sharks. Under high-emission scenarios (Shared Socioeconomic Pathway, SSP5–8.5), our model predicts a shift toward the higher latitudes of the northern hemisphere in basking shark habitats, including temperate and sub-Arctic waters. Ecological corridor analysis identifies critical migratory pathways and pinch points, emphasizing the importance of incorporating the effects of climate change and human activities in the formulation of conservation strategies. The finding underscores the importance of integrated conservation strategies, highlighting how positive human interventions can aid in accurately identifying critical ecological corridors to ensure the long-term survival of the basking shark. Adaptive, science-based conservation measures are crucial to mitigating the effects of climate change and human activities, supporting the resilience of marine ecosystems.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"56 ","pages":"Article e03310"},"PeriodicalIF":3.5,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142699071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
