Applications of the six-category scale have since varied, and divergent implementation practices may undermine its value for marine biosecurity. To support researchers and practitioners to maintain accuracy and precision when applying the scale, we provide a review of LOF-based research and management and updated guidance on its implementation. Focussing on underwater observations and percentage cover metrics (rather than above water observation and species richness) can reduce uncertainty and error. To support users when applying the scale we provide an online application - LOFeR - which features: (i) thousands of underwater vessel images for training and self-assessment, and (ii) an LOF Calculator that can be used in the field to automatically calculate whole-vessel LOF ranks from multiple ranks applied to different underwater surfaces. The LOF scale has been used most extensively in New Zealand to establish biological thresholds and underpin regulations and monitoring for biosecure boating. New Zealand's three-tiered approach to managing boat biofouling addresses boats arriving at the border from overseas, travelling within and between different regions, and visiting marine protected areas.

We used GPS collars to record the space use of 20 raccoons in their invasive range in northern Germany, a landscape dominated by intensive agriculture, including numerous small ponds. These ponds are biodiversity hotspots that act as source habitats and offer shelter and food for local wildlife, including vulnerable species like birds and amphibians. Half of the tracked raccoon individuals showed a weak preference for ponds as foraging grounds, yet the preference for larger waterbodies on the population scale masked this pattern. A detailed look at the intensity of pond use revealed that only a comparably small but highly mobile fraction of the local raccoon population used ponds intensively. These few individuals may thus have a disproportionate large negative effect on native wildlife, leading to a landscape-scale effect by disturbing the most vulnerable yet important habitat islands. Our results suggest that removing few specialized individuals might be an effective and economical strategy to reduce the impact of invasive species on local animal communities.

Thus, mitigating CO2 emissions is critically important not only to promote environmental sustainability across this bloc, but also for the sake of improving global environmental conditions as a whole. Accordingly, this study evaluates whether financial sector development is likely to enable the BRICS countries to curtail emissions associated with their power sectors, while controlling for their natural resource dependency, renewable energy adoption, institutional quality, and international trade participation levels. Regarding novelty, while past studies mostly assessed how financial development and natural resources independently affect total CO2 emission levels, this study also emphasizes the joint impacts of financial development and natural resources specifically on Power Sector-based Carbon-dioxide Emissions (PSCO2) in the BRICS countries. In addition, although past studies checked how natural resources, as a whole, affect CO2 emissions, this study probes further to estimate whether the natural resource-CO2 emissions nexus exhibits heterogeneity across dependencies on different types of natural resources. Accordingly, based on empirical estimates, it is found that as financial sectors in the BRICS countries develop, their yearly PSCO2 are likely to rise as well. Besides, more reliance on natural resources is also found to exert CO2 emission-boosting impacts in the long-run. However, financial sector development and natural resource dependency are jointly observed to mitigate the yearly CO2 emission figures of the BRICS countries. Thus, these findings endorsed that developing the financial sector by providing green financial services can enhance the productivity of natural resource sectors, which, in turn, might enable the BRICS countries to partially offset the PSCO2-boosting impacts associated with natural resource dependency. Moreover, the findings also affirm that annual PSCO2 can be reduced by undergoing the renewable energy transition. Contrastingly, enhancing quality of institution was found to enhance the emissions levels, while international trade's effect on emissions is not statistically conclusive. Furthermore, when disaggregated natural resource data is considered, the above findings are found to hold most natural resource types considered in this study. In addition, the robustness of the findings across alternative estimation techniques is also confirmed by findings derived from the robustness-checking analysis. Therefore, in the BRICS context, these findings highlight the significance of adopting green financial sector development policies, making natural resource-based sectors more productive and less energy intensive, enhancing renewable energy transition speeds, and developing strict environmental institutions.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"394 ","pages":"127527"},"PeriodicalIF":8.4,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145228293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
