文摘The implementation of the ecological protection red line serves as a crucial protective barrier for the conservation of wild plants with extremely small populations by delineating specific geographical areas designated for their conservation.The implementation of a comprehensive set of conservation measures aimed at establishing a biodiversity conservation network for wild plants with extremely small populations has laid the foundation for the health and stability of ecosystems,as well as the harmonious coexistence of humans and the natural environment.Research on the conservation of wild plants with extremely small populations serves as a critical foundation for informing and enhancing the effective conservation of such populations.This paper provides a systematic examination of the theoretical and practical conservation status of certain wild plants with extremely small populations and discusses the conservation trends of these populations within the framework of ecological protection red line delineation.In the future,strategies for the conservation of wild plants with extremely small populations should be integrated with an analysis of the causes of endangerment.This approach will provide a robust foundation for applied research focused on the conservation of these vulnerable plant populations.
文摘With the development of our country’s social economy,the construction scale of water conservancy project has had an obvious expansion.In the construction of water conservancy projects,certain impacts on the surrounding water and soil conditions are inevitable.These impacts may lead to problems such as soil erosion,which can directly affect local production,livelihoods,and the natural ecological environment on which people depend.In severe cases,such issues may even hinder the progress and quality of the water conservancy project itself.Therefore,in the construction of water conservancy projects,soil and water conservation work is extremely important.Based on this,this paper mainly aimed at the prevention and control of water and soil conservation of water conservancy projects launched the relevant analysis and research.

文摘1.Need for coordinated flyways conservation Flyways are migratory routes that encompass breeding,stopover,and non-breeding habitats essential for the annual life cycles of migratory birds(Bamford et al.,2008;Newton,2023).These routes are critical for maintaining global biodiversity by supporting seasonal movements across continents(Hua et al.,2015;Runge et al.,2015).Effective conservation of flyways,such as the East Asian-Australasian Flyway(EAAF)and Central Asian Flyway(CAF),requires international cooperation to protect key stopover sites(Yong et al.,2015;Kumar 2019;Schmaljohann et al.,2022).

文摘As living standards improve,the energy consumption for regulating indoor temperature keeps increasing.Windows,in particular,enhance indoor brightness but also lead to increased energy loss,especially in sunny weather.Developing a product that can maintain indoor brightness while reducing energy consumption is a challenge.We developed a facile,spectrally selective transparent ultrahigh-molecular-weight polyethylene composite film to address this trade-off.It is based on a blend of antimony-doped tin oxide and then spin-coated hydrophobic fumed silica,achieving a high visible light transmittance(>70%)and high shielding rates for ultraviolet(>90%)and near-infrared(>70%).When applied to the acrylic window of containers and placed outside,this film can cause a 10℃ temperature drop compared to a pure polymer film.Moreover,in building energy simulations,the annual energy savings could be between 14.1%~31.9%per year.The development of energy-efficient and eco-friendly transparent films is crucial for reducing energy consumption and promoting sustainability in the window environment.

文摘Climate change has well-documented psychological consequences for society.However,the emotional experiences of frontline conservation professionals remain underexplored.As key knowledge producers and participants in decision-making processes,conservation researchers play a crucial role in shaping and implementing adaptation and mitigation efforts,which are pivotal for effective climate planning.Understanding their emotional responses is essential for enhancing the success of these strategies and supporting climate action.This study aims to identify the most prevalent emotions experienced by conservation researchers regarding climate change across various countries and to examine the qualitative and quantitative factors shaping these emotions.An online survey was conducted with 362 participants from 98 academic and research institutions,utilising both closed and open-ended questions to capture demographic data,climate knowledge,stances on mitigation and adaptation,and emotional responses.Data analysis revealed that feelings of powerlessness,guilt,and concern were most frequently reported,driven by a profound sense of inability to halt climate change,frustration with perceived inaction by governments and industries,and self-assessed personal shortcomings.Age and stances on climate adaptation were identified as primary factors influencing emotional responses,particularly among individuals aged 20–50 and 61–70,with opposition to adaptation correlating with stronger emotional reactions.Demographic factors such as region,place of residence,and mitigation stances played a minor role.These findings provide valuable insights into the psychological well-being of conservation researchers related to climate change.

文摘Global framework for nature management requires identifying areas of high priority for biodiversity conservation and restoration.The unique environments of Qinghai-Xizang Plateau(QXP) provide irreplaceable habitats for biodiversity which is prominent under future climate change.Despite the recent increase in research interest on conservation priorities,there is a lack of comprehensive and targeted protection strategies for pandemic species under climate change.Here,we compiled an exhaustive dataset with the variables of extinction risk and occurrence records of ectothermic lizards to investigate the conservation priorities in the QXP.We assessed the conservation status of the QXP lizards and identified the priority protected areas within the QXP under future climate scenarios using phylogenetic generalized least squares and ensemble species distribution models.Our analyses suggested nine lizard species to be prioritized for protection,with the most critical priority species being Dopasia gracilis,D.harti,and Phrynocephalus putjatai.Moreover,the priority protected areas covered~4.7%area of the QXP,mostly in the southern QXP and southeastern Hengduan Mountains.Protecting these regions would achieve a conservation effectiveness of≥95%for species richness,phylogenetic and functionaldiversity under climate change.Our findings provide realistic guidance for improving the conservation effectiveness of specific-lizard and-regions in the QXP under climate change.Our“bottom-up”approach could help the conservation efforts of other regions and species as an alternative to“top-down”global maps.
