How much biotic nativeness matters across human demographic groups. [PDF]
Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

2019年7月—2020年12月对广东树木公园的鸟类多样性进行调查,对公园内鸟类物种群落结构的动态变化进行了分析。结果表明:公园内分布有繁殖鸟类13目37科81种,其中国家二级重点保护鸟类6种,广东省重点保护鸟类8种;调查的81种鸟类中,优势种3种,常见种15种,稀有种29种,罕见种34种;东洋界鸟类和留鸟占优势;树木公园鸟类多样性存在季节性差异:种类和数量、多样性指数9—12月逐渐上升。树木公园内鸟类群落结构反映了城市森林公园在维持鸟类多样性,以及充当迁徙鸟类的“踏脚石”发挥了重要的作用。

The collective application of shorebird tracking data to conservation
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

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 ...

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 ...

Estimating the total mortality of seabirds following a marine heat wave
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.
