半散放大熊猫育幼期行为谱及PAE编码系统

open access: yes野生动物学报, 2020
2018年8月—2019年1月,在四川省汶川县核桃坪野化培训基地,通过闭路电视监控系统,利用焦点动物取样法观察并记录了大熊猫(Ailuropoda melanoleuca)行为。基于以“姿势—动作—环境”(posture-act-environment,PAE)为轴心,以行为生态功能为依据的PAE编码系统,对育幼期大熊猫的行为进行分类和系统编码并构建PAE行为谱。分辨并记录了育幼期大熊猫及幼体姿势10种,动作49种,环境变量8种。记录到的行为可分为摄食、排遗、育幼、休息、运动和其他行为。基于PAE行为谱,

When and why to give shorebirds a head start

open access: yesConservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

The collective application of shorebird tracking data to conservation

open access: yesConservation Biology, EarlyView.
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

How endorser attributes influence conservation communication

open access: yesConservation Biology, EarlyView.
Abstract Conservation communication often uses the celebrity endorsement strategy. However, robust evidence regarding its effectiveness is still limited. More importantly, practitioners do not have guidelines for selecting an ideal endorser because there is no clear consensus on what endorser attributes are most critical.
