Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia
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 ...

Effects of restoration practices on biodiversity in temperate and boreal forests
Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Birdwatching in Nepal has high potential to support avain biodiversity and tourism. Conservation was identified as the primary motivation for birdwatching, followed by enjoyment and achievement purposes. Health/wellbeing benefits, social and economic factors showed moderate representation, whereas academic motivation played a relatively minor role ...

A link between increased temperature and avian body condition in a logged tropical forest
Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

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.

Mistimed surveys lead to underestimated migratory bird impacts from wind farms
Current guidance and approaches to surveying migratory birds at windfarm developments in Australia are insufficient. Evidence‐based alignment with seasonal presence is needed to improve biodiversity assessment standards, ensuring renewable energy expansion proceeds in a way that better safeguards migratory species and supports global biodiversity and ...

Lessons from an eradication under multiple constraints of an island rat population of record density
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

近年来,生物多样性监测网络的建设得到广泛重视,全球、地区或国家生物多样性观测网不断组建。生物多样性观测的理论框架得到发展,提出了生物多样性核心监测指标(Essential Biodiversity Variables,EBV)。鱼类多样性监测的理论框架包含于生物多样性核心监测指标之内,在遗传、物种、生态系统等多层次进行。基于鱼类监测提出的生物完整性指数(index of biotic integrity,IBI)强调不同物种的生态功能,可以综合反映群落结构和功能的变化,得到广泛应用 ...
