Marine microplastics are a new pollutant that threatens human health and the global marine ecosystem. The public is a direct victim of marine microplastic pollution (MMP), and the public’s behaviour and choices can also play a key role in the management of MMP. Assessing public risk perceptions and treatment preferences for microplastic pollutants can provide a basis for governments to improve the efficiency of pollutant treatment. On the basis of socioeconomic research data from the Jiaozhou Bay region of the Yellow Sea, China, a choice experiment model was used to test the public’s risk perception level and preferences for pollution management. The results of the study revealed that 69.23% of the public could perceive the health risks of marine microplastics. The public had the strongest governance preference for implementing marine microplastic-specific monitoring, followed by support for recycling measures, and the weakest preference for restricting the use of plastic products. Public health risk perception, age, and education influenced governance preferences. The heterogeneity analysis revealed that the public’s governance preferences can be characterized into two groups: “comprehensive governance” and “preventive regulation”. Recycling preferences were not significant in the “preventive regulation group”, with age and risk perception being the main reasons for the differences

Globally, leopards are the most widespread large felid. However, mounting anthropogenic threats are rapidly reducing viable leopard populations and their range. Despite the clear pressures facing this species, there is a dearth of reliable population estimates for leopards across their range, which is particularly important in landscapes consisting of protected and non-protected areas. We used leopard data obtained from camera trap surveys in 2013, 2018 and 2022 to estimate population abundance and density using robust spatial capture-recapture models in a major carnivore site in Nepal. Leopard population in Chitwan National Park, its buffer zone and adjoining forests was estimated 107 (95 % CI: 81–144) with density 3.95 (95 % CI: 2.76–5.2) leopards per 100 km2 in 2022. We documented stable leopard population with a slight decline from 58 (37–77) in 2013 to 48 (34–66) in 2022 in the park. Competition with increasing tiger numbers is a likely consequence for leopards and other carnivores in the protected area. Lower prey density, human-carnivore conflict through livestock depredation, and canine distemper virus with a large domestic dog population are major threats to leopards outside the park. To reduce these threats, we suggest that conflict mitigation measures be intensified, and the impact of disease on large carnivores quantified in this important carnivore landscape.

Marine ecological restoration, as a pivotal component of constructing marine ecological civilization, provides a quantifiable insight into the premium effect it exerts on the surrounding real estate market. This holds substantial reference significance for optimizing the spatial allocation of marine ecological resources and enhancing the well-being of coastal residents. Leveraging marine ecological restoration projects conducted in Shandong Province from 2011 to 2015 and aligning them with second-hand housing transaction data from Qingdao, Yantai, and Weihai in Shandong Province spanning from January 2008 to October 2021, this study employs machine learning techniques and Difference-in-Differences methodology to delve into the impact of marine ecological restoration on surrounding housing prices. The empirical findings unveil a significant real estate premium effect triggered by marine ecological restoration initiatives. Post-project completion, there is a notable upsurge in housing prices within a 3-kilometer radius of the restoration sites. The efficacy of ecological restoration in influencing housing prices is attributed to its ability to enhance water quality in the vicinity of the project sites, with this effect exhibiting spatial decay characteristics. Moreover, noteworthy disparities are observed in the real estate premium effects of marine ecological restoration projects based on varying funding scales and restoration types. To capitalize on these findings, it is recommended to integrate marine ecological restoration into long-term urban development planning initiatives, actively advocate for nature-based restoration solutions, fully harness the scale effects of restoration projects, and steer towards achieving socio-economic green development objectives.

Protected areas represent a major tool for biodiversity conservation in the face of environmental change. However, species will need to shift their distribution to track their suitable climate, which calls the need to create new protected areas and take into account those changes. We modelled the suitable environment of 11 tetrapods (three reptiles, three amphibians, and five mammals) that dwell in the eastern forest corridor of Madagascar with an Ecological niche modelling approach adapted to small sample size and sample bias. We took into account the habitat (forest cover), two climate data sources (Worldclim and CHELSA), two scenarios of projected future climate change and three global circulation models, and quantified the change in suitable environments at the presence points and at the location of a candidate protected area in SE Madagascar (Beampingaratsy forest). We predict a decline in climate suitability for all species at their current locations. We propose to elevate the IUCN conservation status of five species to a threatened category, relying on criterion A3 (projected population decline). We also found that suitability will increase at the location of the candidate protected area for eight species. Granting a strong protection status in this region will ensure an ecological continuity between two National Parks, and contribute to help species track their suitable environments in the future.

The Atlantic Forest is one of the most degraded biomes in Brazil and that makes it a global biodiversity hotspot. The torrent-frog genus Hylodes is endemic to this region and eight of its species are threatened with extinction to some degree. Hylodes sazimai, one of the threatened species, is facing conservation challenges that range from destruction of its restricted habitat to global climate changes. In this study, we used phylogenetic analyses and ecological niche modeling approaches to assess a newly discovered population, the spatial distribution of this species, and reassess its conservation status. The phylogenetic analyses recovered the new population within H. sazimai with strong support and the ecological niche modeling had a satisfactory performance, highlighting suitable areas for the species. However, even with this newly found location the threat category in the national and state level assessment did not change, due to the still small extension of occurrence and plethora of threats to its conservation in nearly all known populations. We recommend an update to the international level assessment to better reflect the current conservation state of the species. Finally, we advocate for the preservation of water bodies and riparian forests throughout the species range of distribution. Furthermore, we encourage the search for new areas of occurrence in forested areas that have water bodies focusing on the areas brought by the modeling as suitable for the species and advocate for the use of phylogenetic analysis to accurately distinguish between the similar species within the genus.

The rapid decline of the African penguin Spheniscus demersus in the early 2000 s triggered the drafting of the first African Penguin Biodiversity Management Plan (BMP) published in 2013, to “halt the decline of the African penguin population”. Working Groups (WGs) were created with stakeholders involved in penguin conservation to facilitate the implementation of the BMP. This study reviews the execution of the plan (1) from aide memoires and reports circulated within these WGs between 2013 and 2022; (2) by interviewing (in 2023) some of the stakeholders involved to assess their perceptions of the BMP 10 years post-implementation; and (3) by assessing the effectiveness of some actions using available scientific data. Interviewees unanimously agreed that the plan improved the species’s management and facilitated collaboration across institutions involved. Conservation actions identified as the most effective were 1) the rehabilitation of adults and chicks; 2) predator management and 3) habitat improvement with the provision of artificial nests. Scientific reviews of these actions validated their success. For example, rehabilitation effort may have increased the 2023 penguin breeding population by ca 7 %. Nevertheless, African penguin numbers continued decreasing and the species is now “Critically Endangered” on the IUCN Red List. Measures are still lacking in effectively increasing prey availability despite intensive engagement. Dedicated funding, trained capacity and accountability by relevant institutions undertaking their actions and deliverables were identified as essential for a more successful implementation of the BMP. Lessons learnt may pave the way for stronger conservation actions for African penguins and other threatened seabirds.

Most endangered species are in a critical state of survival, and natural recovery in their native habitats is unlikely. Determining the optimum water level that affects the growth and survival of aquatic plants is crucial for their restoration. In the present study, we investigated the effects of different water levels on the growth of Korean endangered aquatic plant Cicuta virosa L. in two experimental environments: a greenhouse and a reservoir. The water level was adjusted to three conditions (−15 cm, 0 cm, and 15 cm) and 1- and 2-year-old plants were used. The plant height, root collar diameter, rhizome volume, and growth and survival rates were measured. In the greenhouse experiment, for 1-year-old plants, the best growth rate was observed at water levels of −15 ∼ 0 cm, but for 2-year-old plants, good growth rate was observed at water levels of 0 cm. The growth of rhizome volume was not affected by water level. In the on-site experiment at the reservoir, the different growth rates was not showed according to the water level, but the survival rate was good at −15 cm water level. However, the low survival rate (50 %) of C. virosa L. within the natural habitat remains a limitation of this study, and a strategy to increase survival rates when they are exposed to various natural threats is necessary.

We present data on the population density and distribution of Corncrake breeding sites across a broad region of North-eastern Italy, collected over a 30-year period. Additionally, based on an extensive literature review, we conducted a literature review about driving forces, anthropogenic threats, related mechanisms, and impacts affecting this species of conservation concern in breeding sites. In the North-eastern Alps, Corncrake populations have experienced a significant decline in local density from 1993 to 2024, with a particularly dramatic decrease between 2012 and 2013. Grouping data for decades, in the 11 sites we recorded 47.2 ± 12.21 males in 1993–2002; 30.5 ± 6.96 in 2003–2012 and 7 ± 3.33 in 2013–2024. The population decline in the Friuli region was accompanied by significant range contraction—by the end of the study period, the species was present at only 40 % of the surveyed sites. Similar trends of decline have been reported in other Alpine regions, though with varying timeframes depending on local contexts. The declining trend is strongly linked to socio-economic driving forces, particularly those related to European agricultural policies. These policies have been identified as the primary drivers behind changes in mowing regimes. However, local variations between sites highlight how both threats and corresponding conservation measures are highly dependent on the geographical context. The framework of this situation suggests that anthropogenic threats can be divided into three main categories of driving forces: (i) local changes in disturbance regimes, primarily related to meadow mowing; (ii) regional changes in land use; and (iii) large-scale climate change. Since the driving forces and threats may differ in terms of spatial and temporal scales, as well as in local conditions, further analyses should incorporate quantitative approaches, such as expert-based evaluations, to rank and prioritize threats.

Since the driving forces and threats may differ in terms of spatial and temporal scales, as well as in local conditions, further analyses should incorporate quantitative approaches, such as expert-based evaluations, to rank and prioritize threats.</div></div>","PeriodicalId":54898,"journal":{"name":"Journal for Nature Conservation","volume":"86 ","pages":"Article 126922"},"PeriodicalIF":2.2,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

The new Common Agriculture Policy (CAP) intends to give more freedom to countries to manage their budget while increasing funding for income support and provisioning of climate public goods from agriculture and farming. For the past 20 years this has been operationalised through incentivising farmers’ contract participation in agri-environmental schemes (AES). In this paper we examine through a two-stage approach, farmer preferences for contract characteristics in a multi-European country Discrete Choice Experiment (DCE) and the determinants of land enrolment in contracts. Overall, we find that longer contracts and high administrative burden decrease the probability of enrolling in a contract over the base levels while shorter contract length and provisioning of advisory support are desirable. Amongst all available contract options, converting arable to grassland options was by far the one that participants asked the most compensation for, across countries. We also find that past experience with agri-environmental schemes and socio-demographics have a strong and statistically significant effect on the percentage of land enrolled, while contract characteristics do not influence enrolment. Finally, we present some evidence of position-ordering effects affecting preferences for contracts and their characteristics but not influencing contract enrolment. Understanding the true cost incurred by farmers to implement AES is crucial for policymakers as failure to do so can make farmers ask for much higher compensation, per hectare, potentially to cover costs of transitioning to different types of farming or to incorporate financial risk by significantly altering their farm practices.

Savannas are the second largest biome in the world and are known for being essential hotspots of diversity, playing a crucial role in carbon storage, nutrient cycling, and climate regulation. Given its importance at a global level, this research presents a literature review on the application of remote sensing to identify the drivers of deforestation in savannas worldwide. The Web of Science and Scopus databases were used for this purpose, and systematic analyses was conducted. From a systematic perspective, articles addressing the main drivers of deforestation in savannas, remote sensing products, perspectives, and methodologies for identifying deforestation drivers at different spatial scales were considered. From a bibliographic perspective, the results revealed 169 papers. The results of the systematic review showed that agriculture and cattle grazing are the main drivers of deforestation in savannas. Other important drivers of savanna degradation, such as forestry, reforestation, mining activities, and the invasion of exotic grasses, are generally underrepresented drivers of deforestation. Regarding the methodological approaches used to identify the drivers of deforestation in savannas, the most common include assessing transition matrices and land cover changes. LANDSAT and MODIS were the most commonly used remote sensing products. Finally, despite the crucial role of savannas at the global level, studies on deforestation drivers in this biome are less developed compared to biomes such as tropical forests, which have received greater academic attention. Thus, this research contributes to identifying gaps in current knowledge, highlighting the relevance of new methods and new studies in this ecosystem.
