Methodology to identify ecologically matching areas and its applications in conservation planning
Abstract Identifying ecologically matching areas is both challenging and critical for understanding spatial patterns of biodiversity and advancing conservation planning. However, existing approaches often lack spatial flexibility, overlook shape and size constraints, or rely on limited environmental parameters, reducing their effectiveness in real ...

Abstract In response to demand for better biodiversity stewardship from the private sector, frameworks such as the Taskforce on Nature‐related Financial Disclosures (TNFD) have been developed to help companies assess, manage, and disclose their nature‐related impacts, dependencies, risks, and opportunities.

The obsolescence of protected area categories in a polycrisis world
Abstract Current global conservation models face significant limitations in addressing the global polycrisis, and the constraints of the International Union for Conservation of Nature protected area (PA) classification system are part of the issue. The principles of the new conservation paradigm—governance, equity, and interculturality—are not viable ...

海底地下水排泄(SGD)是海岸带陆海相互作用的一个重要的自然过程.系统介绍SGD的发生过程及其定量测定的方法,并通过水文计算和野外调查,在估算了区域海底地下水排泄量和分析了海水与地下水中氮、磷、碳等营养物质差异的基础上,讨论了SGD对近海海域生态环境的潜在影响,这对正确区分近岸海域营养物质的来源和认识中国沿海水域频繁发生的赤潮藻暴发性增殖事件的原因,具有重要的理论和实践意义.

Early outcomes of England's new biodiversity offset market
Abstract Nature markets are being operationalized as a tool to address the biodiversity finance gap and achieve global biodiversity targets. However, there is limited understanding of how the outcomes of these markets align with biodiversity targets.

野生动物的生境可能会在时间和空间上发生变化。在某一地区,各种生境所占比例的变化,可能引起该地区野生动物对整个生境适宜性的改变。因此,需要一个预测野生动物对生境变化所产生反应的生境关系模型(Verner et al, 1986)。本文根据野生动物短期的生境利用和野生动物管理中收集到的有关资料,提出了一种预测生境变化对野生动物影响的方法。生态学上关于生境选择理论是以种群密度大小表示生境质量好坏为前提的。故根据生境利用以及有关资料,便能直接地预测生境变化的结果。一、理论基础 ...

气候变化是导致生境丧失和生物多样性下降的主要因素之一。研究气候变化对物种生境的影响对于保护物种多样性,维护生态系统功能完整性具有重要意义。本研究以新疆为研究区域,以塔里木兔、草兔和雪兔为研究对象,选取可能影响它们生境分布的10个环境因子,利用MaxEnt模型预测它们当前和未来RCP 4.5和RCP 8.5两种气候情景下2041—2060年(2050s)、2061—2080年(2070s)的潜在生境分布,并找出影响生境分布的关键因子。研究结果表明,模型预测新疆兔属3个物种生境分布的精度达到较高水平 ...

Protected areas on international borders show uneven conservation outcomes
Abstract Border protected areas (BPAs) are national protected areas that are immediately adjacent to a country's border or span two or more countries; they are characterized by distinctive opportunities and pressures. They play a critical role in protecting carbon‐rich ecosystems, conserving endangered biodiversity, reducing cross‐border environmental ...
