We find that political connections hinder firms' green innovation, indicating the existence of the political resource curse. Our moderating effect analysis shows that the higher the degree of digitalization of firms, the more significant the decrease in the negative effect of political connections on green innovation, thereby breaking the political resource curse. Heterogeneity analysis shows that the positive moderating effect of digitalization is higher on private firms and firms with more redundant resources. Finally, mechanistic analysis indicates that political connections hinder firms' green innovation by reducing operational efficiency.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"380 ","pages":"124992"},"PeriodicalIF":8.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143741772","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}

Wind energy is an attractive option due to its low cost and sustainability, but it poses significant risks to birds and bats through collisions and barotrauma with wind turbines. We examined the main ecological traits linked to wind turbine mortality in 214 bird and 19 bat species in peninsular Spain. We assessed the vulnerability of bird and bat assemblages to help understand the potential impact of wind energy development on the most vulnerable assemblages. Our findings indicate that bird and bat casualties were driven by morphological and ecological traits. For birds, scavenger species, those with partial migratory patterns, and aerial lifestyles were most affected by turbine collisions. We also found that vulnerability was positively correlated with observed mortality rates at the province level, but the effect was weaker for birds. Sensitive areas for birds and bats are located in southern, south-eastern, and central Spain, with birds showing additional vulnerability in western and northern regions, while future wind energy development affects bats more in eastern Spain. Our research highlights the importance of mitigating impacts on vulnerable bird and bat species, as well as abundant species. The study highlights the potential risk of ecosystem function loss for bird and bat assemblages due to wind energy projects. We provide spatial tools to identify high-vulnerability areas, guiding energy development to minimize ecological impacts.

After dam construction, all four sites experienced significant changes in environmental conditions. Deterministic processes, particularly environmental filtering, dominated in structuring fish communities.

The upper sites (LPB, CST, and TLS) displayed a distinct seasonal pattern in FD indices, with values decreasing during the dry season and increasing during the wet season. Conversely, the lower site (VCM) exhibited the opposite. Water level emerged as the key driver across all sites, with temperature and total nitrogen as secondary drivers.

In areas experiencing LUC, a negative relationship between LAI and surface temperature leads to a positive feedback, which reinforces decreasing LAI and increasing warming. Moreover, prolonged regional dry conditions and a shift towards drier climate conditions further exacerbate LAI reductions. These climate change impacts have a large spatial variation and cause western South America to show the most pronounced LAI sensitivity to LUC under the shared socioeconomic pathways (SSP) 3-7.0 scenario.

A graphene coating was deposited on the biodegradable sponges (FG evaporator) and was evaluated to desalinate seawater (from Puerto-Vallarta Beach, Mexico) under natural sunlight. This evaporator produced an evaporation-rate/evaporation-efficiency of 1.55 kg m^-2·h^-1/77.3 %.

However, existing studies on dual carbon goal-oriented LULC optimization often overlook potential ecological risks while emphasizing benefits and fail to fully explore the possible \"double-edged sword effect\" of LULC optimization. To address this gap, a multi-scenario, multi-objective integrated LULC optimization model was developed in this study, considering both 2030 carbon peaking and 2060 carbon neutrality. Landscape ecological risk (LER) was introduced as an additional evaluation dimension. Furthermore, an integrated three-dimensional (LER, carbon emissions, and carbon storage) evaluation system was established to identify key areas in Shanxi Province to achieve dual carbon goals. The results show that, compared to the natural development (ND) scenario, the optimized scenarios better balance economic and ecological value, reduce carbon emissions, and increase carbon storage, with the carbon neutrality (CN) scenario performing the best. However, LULC optimization also leads to an increase in the LER, particularly in the CN scenario.

Since microbial diversity, metabolic richness, and interactions of rhizosphere microbes are much higher than those microbes in bulk water, it suggests that rhizosphere microbes may reduce suspended microbes in water via their competitive effects, thus purify pollutants and reduce turbidity in bulk water (improve transparency).
