Consequently, there is an urgent need to ensure ecosystem recovery in post-mining landscapes. Seed dispersal mutualisms play a central role in plant reproduction, colonization, and recovery in degraded habitats. Here, we released 37,800 seeds to assess the effect of open-pit marble mining on rodent-mediated seed dispersal and plant recruitment, and to examine the natural recovery of seed dispersal processes at active mines compared with two decadal intervals of mine abandonment. Although mine categories did not significantly affect seed removal, they significantly disrupted rodent-mediated seed dispersal processes through truncating dispersal distances. Seed dispersal also varied with disturbance-distance categories; however, effects differed across mine categories. Seed dispersal functions had not substantially recovered 20–23 years after mining abandonment and continued to exhibit impairment similar to active mines. Furthermore, seed predation rates remained higher and dispersal distances were shorter than in natural forests. Across mine categories, seed dispersal functions were greatest for 10–13 years abandoned sites, at an intermediate recovery stage, consistent with a typical peak in mid-successional habitat ecosystem functional complexity. Our findings emphasize the critical role of animal-plant interactions in ecosystem recovery, showing that mining disrupts animal-mediated seed dispersal for decades, hindering regeneration. Mining impact assessments must therefore weigh the long-term ecological trade-offs of impaired seed dispersal and establishment against the value of the extracted mineral when assessing post-mining recovery.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"311 ","pages":"Article 111440"},"PeriodicalIF":4.4,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144893029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, to address this research gap, this study takes a sample of 493 Chinese firms and employs structural equation modeling to conduct empirical analysis. The empirical results indicate that the three types of institutional pressure (coercive pressure, normative pressure, and mimetic pressure) all promote corporates in disclosing biodiversity information. In addition, coercive pressure, normative pressure, and mimetic pressure are all capable of promoting corporate ecosystem service management and green supply chain management, and both corporate ecosystem service management and green supply chain management facilitate the disclosure of biodiversity information by corporates. Furthermore, the mediating roles of both corporate ecosystem service management and green supply chain management have been validated, and the difference in the mediating effects of these two variables has not reached a significant level.

Systematic reserve site selection algorithms were implemented to identify important conservation areas for the breeding habitats of Laridae in Cuba, considering four of the most significant human pressures: fishing, wind farms, coastal tourism and nightlight pollution. Several conservation scenarios were tested by varying protection targets and weights assigned to the human pressures. A conservation scenario was also proposed considering the future wind farms development plan for Cuba. The conservation areas identified were compared with the existing marine protected areas to highlight conservation needs for Cuban Laridae. Spatial patterns of the proposed areas were relatively consistent across different socioeconomic prioritisation scenarios, regardless of the conservation target. More than 71 % of the surface of the proposed conservation areas is not covered by the current Cuban marine protected areas. The methodology employed in this study can significantly enhance the efficiency of marine spatial planning decision-making, and underscores the value of incorporating detailed socioeconomic data.

We investigated the composition and foraging patterns of diurnal and nocturnal woodland ant communities, and their responses to an experimental exposure to ALAN over 15 days. We detected a high turnover in community composition between diel periods, with nocturnal communities comprising fewer species, removing 73 % less insect biomass, but displaying stronger recruitment to protein resources than diurnal communities. Relative to unlit controls, no significant effect of ALAN was detected on any aspect of ant community structure and foraging. Our results demonstrate that the partitioning of diel time and resource type is an important coexistence mechanism maintaining ant biodiversity, and suggest that a brief exposure to ALAN does not significantly impact the foraging activities of ecologically dominant generalist ant species. While further research is needed to ascertain the long-term effects of ALAN exposure on ant biodiversity, the limited impacts in the short-term may be explained by nocturnal ant species' reliance on chemical cues and other non-visual navigational strategies, in contrast to flying insects for which strong impacts of ALAN have been documented.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"311 ","pages":"Article 111439"},"PeriodicalIF":4.4,"publicationDate":"2025-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144861208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
