摘要

物种基线信息是有效保护生物多样性的必要条件。在这里,我们提供了可靠的生态数据,以支持对2016年发现的Principe Scops-owl, Otusbikegila Melo, Freitas, Verbelen, Costa, Pereira, Fuchs, Sangster, Correia, de Lima和Crottini 2022的有效保护。我们绘制了观察到的和潜在的分布,推断了栖息地关联,估计了种群规模,并评估了该物种在国际自然保护联盟(IUCN)红色名录中的分类。在长旱季和短旱季期间,在Príncipe岛上进行了调查,记录了沿样带采样点的猫头鹰存在情况。这些数据被用来模拟分布,显示普林西比鸮被限制在岛南部34.4平方公里的范围内,在Príncipe Obô自然公园内。大多数记录来自较低海拔的原始森林。偏远程度是解释岛屿水平存在的最重要变量,其次是土地利用,这表明该物种仅限于森林,明显依赖于原生森林。使用不同模型的距离抽样表明,种群密度在33.4个体/km2 (95% CI: 23.6-47.2)和46.4个体/km2 (95% CI: 29.3-73.6)之间,推断种群规模在1,149个体(95% CI: 813-1,623)至1,597个体(95% CI: 1,007-2,533)之间。我们认为该物种属于“极度濒危”物种,因为它的发生范围小,并且在单一地点发生,并且推断出发生范围、占用面积、成熟个体数量和栖息地面积、范围和质量的持续下降。对普林西比鸮的有效保护需要定期监测和进一步研究,重点是引进的哺乳动物的繁殖和潜在的巢穴捕食。对自然公园保护的广泛支持对于确保该物种及其所依赖的Príncipe特有丰富的原生森林的保护至关重要。

The recently discovered Principe Scops-owl is highly threatened: distribution, habitat associations, and population estimates
Species baseline information is required for effective biodiversity conservation. Here we provide sound ecological data to support effective conservation of the Principe Scops-owl, Otusbikegila Melo, Freitas, Verbelen, Costa, Pereira, Fuchs, Sangster, Correia, de Lima & Crottini 2022, discovered in 2016. We mapped the observed and potential distribution, inferred habitat associations, estimated population size, and assessed the International Union for Conservation of Nature (IUCN) Red List category for this species. Surveys were carried out across Príncipe Island during the long and short dry seasons, recording owl presence in sampling points along transects. These data were used to model distribution, revealing that the Principe Scops-owl is restricted to 34.4 km2 in the south of the island, inside the Príncipe Obô Natural Park. Most records were in lower altitude native forest. Remoteness was the most important variable to explain presence at island level, followed by land use, which showed that the species is restricted to forest, clearly depending on native forest. Distance sampling using different models suggested a population density ranging between 33.4 individuals/km2 (95% CI: 23.6–47.2) and 46.4 individuals/km2 (95% CI: 29.3–73.6), which extrapolates to an estimated population size ranging from 1,149 individuals (95% CI: 813–1,623) to 1,597 individuals (95% CI: 1,007–2,533). We propose that the species is classified as “Critically Endangered” due to the small extent of occurrence, coupled with occurrence in a single location and inferred continuing declines in the extent of occurrence, area of occupancy, number of mature individuals and area, extent, and quality of habitat. Effective conservation of the Principe Scops-owl requires regular monitoring and further studies focusing on reproduction and potential nest predation by introduced mammals. Widespread support for the conservation of the Natural Park is vital to ensure the protection of this species and the endemic-rich native forests of Príncipe on which it depends.
