Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Conservation Biology, EarlyView.Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

生态环境与保护随着全球城市化进程的加速,河流生态系统面临着前所未有的压力。城市化导致的河道硬质化、水文情势改变和栖息地破碎化是河流连通性下降的主要原因。这种连通性下降直接导致了水生生物多样性的降低,特别是对鱼类和无脊椎动物的物种丰富度、群落结构和功能多样性产生了显著负面影响。基于研究结果,本文提出了一系列基于自然的解决方案和适应性管理策略,以促进城市化进程中河流生态系统的保护与恢复。

Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Conservation Biology, EarlyView.Abstract Although significant biodiversity has been safeguarded by protected areas (PAs), biodiversity trends continue downward. Within the frameworks of the EU Biodiversity Strategy for 2030 and the new EU Restoration Regulation (2024), conserving critical biodiversity areas is essential.

工程建设土地整治不仅是改善农业生产条件与优化土地利用格局的重要手段，也是推动区域生态系统恢复与提升生物多样性的重要途径。生态廊道的建设作为土地整治项目区中的核心环节，能够有效改善破碎化生境，增强物种迁移与基因交流，提升生态系统的稳定性与韧性。通过合理布局生态廊道，可实现农田、林地与水域的有机联系，缓解人类活动对生态系统的干扰，从而在区域尺度上形成多层次、多功能的生态网络。评估其效应不仅关系到生物多样性的持续保护，也为土地整治与生态文明建设的协调发展提供了科学依据。

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia
Conservation Biology, EarlyView.Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

Conservation Biology, EarlyView.Abstract Procedural, distributional, recognitional, and epistemic justice aspects of conservation interventions are well documented in contexts where pastoralism is a key livelihood and way of life. Geospatial analyses and representations of wildlife conservation and restoration that are increasingly applied in pastoralist rangeland socioecological ...
