野生动物学报为了解蓝冠噪鹛（Pterorhinus courtoisi）的灭绝风险，预测未来种群变化趋势，采用Vortex 10.5.0模型对蓝冠噪鹛进行种群生存力分析，并模拟不同参数对蓝冠噪鹛种群数量的影响，探索制约蓝冠噪鹛种群增长的主要因子，为该物种的保护管理提供科学依据。结果显示：在标准状态下（考虑近交、灾难因素），蓝冠噪鹛灭绝概率为73%，内禀增长率（R）为0.148 0，周期增长率（λ）为1.159 5，净生殖率（R0）为1.504 6，雌性和雄性的平均世代时间（T）为2.76 a。在9个参数敏感度分析中，

基于种群生存力分析的陕西铜川朱鹮再引入种群的可持续性及保护对策
野生动物学报种群生存力分析（population viability analysis，PVA）虽然已经在濒危物种的保护管理中得到广泛应用，但目前面临的严峻挑战是如何采用PVA分析影响濒危物种种群长期维持的内外因子。经过数十年的保护，朱鹮（Nipponia nippon）野生种群的数量已经从7只增长到约4 400只，若干再引入计划也分别在中国、日本和韩国相继实施。过去的研究表明，种群统计随机性、灾害和种群性比等因素是影响朱鹮野生种群稳定增长的主要因素，然而，对影响朱鹮再引入种群长期稳定维持的因素却知之甚少 ...

Conservation Biology, EarlyView.Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

Functional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1143-1160, April 2026.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that

, 2020 日益加剧的环境变化与人类活动严重威胁种群的生存,因此预测多种胁迫下种群的命运至关重要。种群生存力分析(population viability analysis, PVA)是评估种群所受威胁、灭绝或衰退风险以及恢复可能性的有效方法。基于物种及环境数据和建模,种群生存力分析能够整合不同类型变量,为目标物种的保护提供建议。然而,极小种群野生植物的个体数据难以获取,种群参数估计困难,这导致传统种群生存力分析方法在此类种群中的应用存在局限性。在此,本文提出了极小种群野生植物生存力分析的潜在方法 ...

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.
