Lessons from seabird conservation in Alaskan longline fisheries
Conservation Biology, Volume 33, Issue 4, Page 842-852, August 2019., 2019 Abstract Although bycatch of seabirds and other long‐lived species is a critical conservation issue in world fisheries, case studies documenting significant reductions in the mortality of these low‐productivity species in a fishery are rare. We studied progress toward seabird conservation in the Alaskan longline fisheries, one of the largest and most ...

How much biotic nativeness matters across human demographic groups
Conservation Biology, EarlyView.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 ...

Conservation Biology, EarlyView.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.

The Definition of Mangrove Forest and Protection of Mangrove Wetland [PDF]
, 2010 红树林保护刻不容缓,但目前的保护现状并不乐观,尤其是在忽视其湿地本质和生态系统的情况下,单纯的有林地保护现象甚为突出。针对以上问题,从红树林名称入手指出红树林的林学渊源,理清概念,分析保护现状,并从生态系统的角度阐述了红树林湿地结构和功能的整体性,探讨和呼吁科学的管理和保护。Mangrove protection does not permit any delay, however, the current situation is not optimistic.Especially ...

Finding floral and faunal species richness optima among active fire regimes
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Ecological safety assessment of egrets in Xiamen National Nature Reserve [PDF]
, 2006 [摘要]：白鹭的生态安全是指白鹭所处的生态系统能够维持白鹭种群持续生存的需求和条件, 其中关键是白鹭生境的安全。白鹭 生境安全从根本上取决于生境的适宜性和人为对生境的干扰程度, 又可以理解为生境受到人类干扰后所能保持的生态适宜性。 分别选择白鹭在厦门的2 个主要繁殖栖息生境 大屿岛和鸡屿岛和10 个代表性觅食生境为研究对象, 对白鹭生境的生态适 宜性和人为干扰程度进行分别评价。其中, 生境适宜性评价采用指标体系法, 通过赋值、计算进行评价; 人为干扰程度评价主要 依靠地理信息系统分析方法 ...
