野生动物学报保护或创造破碎化生境中的景观连通性被认为是保护生物多样性、生态系统以及促进野生动植物种群的流动和适应气候变化的关键战略，而生境廊道是恢复和保护景观连通性的常用策略。以塔里木盆地为例，结合该区域内叶城沙蜥（Phrynocephalus axillaris）21个栖息地分布点数据，运用MaxEnt模型对该区域叶城沙蜥的生境适宜性进行分析，并综合植被类型、地理因素、人为干扰等因素，利用Linkage Mapper工具构建适宜叶城沙蜥扩散的潜在生境廊道。结果表明 ...

基于鸟类栖息地营建的城市湿地公园景观设计——以佳木斯柳树岛为例
野生动物学报城市湿地公园具有极高的生态价值与社会价值，鸟类作为生态系统的重要指示物种，为其营造适宜生存的栖息地，对于维护城市湿地生物多样性具有重要意义。为了给东北地区城市湿地公园中鸟类栖息地的修复、规划及管理提供参考，以黑龙江省佳木斯柳树岛为研究对象，通过解析柳树岛景观类型，调查鸟类资源，分析不同景观斑块与鸟类多样性的关系，提出基于鸟类栖息地营建的城市湿地公园景观设计策略，主要包括：对鸟类栖息地进行分区保护、退化生境修复、生态廊道构建、自然岸线及水环境恢复、营建适宜生存的植被群落和后期监测管理等。

Identifying potentially suitable and accessible refugia to mitigate impacts of an emerging disease on a rare tree. [PDF]
Conserv BiolAbstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Effects of snake fungal disease (ophidiomycosis) on the skin microbiome across two major experimental scales. [PDF]
Conserv BiolAbstract Emerging infectious diseases are increasingly recognized as a significant threat to global biodiversity conservation. Elucidating the relationship between pathogens and the host microbiome could lead to novel approaches for mitigating disease impacts.

Integrative Conservation, Volume 2, Issue 4, Page 201-213, December 2023., 2023 Livestock disturbances decreased the area of suitable habitat of forest pheasants by 14.28% in 7 years. Livestock activities remarkably increased the nest failure rate (by 2.18 times) of forest pheasants. Abstract The degradation and fragmentation of natural habitats, driven largely by anthropogenic activities such as grazing, represent growing ...

Wildlife Letters, Volume 1, Issue 2, Page 71-78, June 2023., 2023 Oaks are often removed as part of longleaf pine restoration; however, it is unclear if oak patches produce important resources for native wildlife. We studied wildlife use of the transition between longleaf pine woodlands and hardwood hammocks. We found these areas support a variety of wildlife species and future management and restoration of longleaf ...

Conservation Biology, Volume 37, Issue 3, June 2023., 2023 Abstract Many species are restricted to a marginal or suboptimal fraction of their historical range due to anthropogenic impacts, making it hard to interpret their ecological preferences from modern‐day data alone. However, inferring past ecological states is limited by the availability of robust data and biases in historical archives, posing a ...

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Conservation Biology, EarlyView.Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...
