Assessing the impact of working landscapes on biodiversity and defining locally contextualized management guidelines for productive activities are key for sustainability. Occupancy dynamics provide information about sites in the landscape that are either avoided or preferred by populations through the estimation of extinction and colonization probabilities, respectively. We identified the habitat traits that affected colonization and extinction probabilities of target birds (forest-dependent, endemic, or conservation-concern species) within a Neotropical working landscape by using multi-season occupancy models to point-count data collected through a participatory monitoring approach, and considering our imperfect detectability of species in the field. We provided colonization and extinction scenarios according to local land uses (forestry plots, urban-cropfield areas, conservation forests) to recommend management activities that could have a positive impact on bird conservation.

评估生产性景观对生物多样性的影响,并为生产活动制定本地化管理指南,是实现可持续发展的核心要务。占据动态(occupancy dynamics)通过分别估算灭绝概率与定殖概率,可揭示景观中被物种种群规避或偏好的位点信息。本研究依托参与式监测方法采集的点计数数据(point-count data),结合野外物种检测不完善的实际情况,运用多季占据模型(multi-season occupancy models),在新热带区(Neotropical)生产性景观中,明确了影响目标鸟类(依赖森林的特有物种、受关注保护物种)定殖与灭绝概率的栖息地特征。本研究基于当地土地利用类型(林业用地、城镇农田区域、保护林)构建定殖与灭绝情景,据此提出可对鸟类保护产生积极影响的管理活动建议。灌丛(Shrub c...)
