Abstract Biodiversity is declining across Europe. Modern agricultural practices, habitat fragmentation, land abandonment and climate change are key factors causing current trends in environmental change. Mobile organisms such as raptors, positioned high in the food chain, are good indicators of negative or positive landscape dynamics, since their response is fast. This assumption was tested by investigating the Scops Owl (Otus scops) population in a traditional Central European cultural landscape (Goricko Nature Park [GNP]) in Slovenia. The negative trend in male calling Scops Owls was correlated with static and dynamic environmental change variables derived from remotely sensed or field-based, multi-temporal data sources. Key geospatial predictors were identified and used for bird calling and breeding (C&B) suitability modelling. All geospatial models developed predicted a decline in C&B suitability (even by 33%) in almost all areas where the bird is currently active. However, the NE part of the GNP could achieve better C&B conditions for theScops Owl in the coming years (a potential 36% increase in suitability). Predictions indicate that more effort and action, to conserve the Scops Owl in the study area should be implemented in the N, NE and E part of the hilly GNP. Our results are thus highly applicable not just for decision makers in this protected area but rather in all areas across the Scops Owl’s continental population, since the methodology is easily replicable and transferable.

人为环境变化压力下的斯科普斯猫头鹰(Otus scops)

摘要 整个欧洲的生物多样性正在下降。现代农业实践、栖息地破碎化、土地废弃和气候变化是导致当前环境变化趋势的关键因素。移动生物,如猛禽,位于食物链的高位,是负面或正面景观动态的良好指标,因为它们的反应速度很快。通过调查斯洛文尼亚传统中欧文化景观(Goricko Nature Park [GNP])中的 Scops Owl (Otus scops) 种群来检验这一假设。雄性叫 Scops Owls 的负面趋势与源自遥感或基于现场的多时态数据源的静态和动态环境变化变量相关。确定了关键的地理空间预测因子,并将其用于鸟类鸣叫和繁殖 (C&B) 适宜性建模。所有开发的地理空间模型都预测,在鸟类目前活跃的几乎所有地区,C&B 的适用性都会下降(甚至下降 33%)。然而,GNP 的 NE 部分可以在未来几年为 the Scops Owl 实现更好的 C&B 条件(适用性可能增加 36%)。预测表明,应该在丘陵 GNP 的 N、NE 和 E 部分实施更多的努力和行动,以保护研究区的角鸮。因此,我们的结果不仅适用于该保护区的决策者,而且适用于 Scops Owl 大陆种群的所有地区,因为该方法很容易复制和转移。GNP 的 NE 部分可以在未来几年为 the Scops Owl 实现更好的 C&B 条件(适用性可能增加 36%)。预测表明,应该在丘陵 GNP 的 N、NE 和 E 部分实施更多的努力和行动,以保护研究区的角鸮。因此,我们的结果不仅适用于该保护区的决策者,而且适用于 Scops Owl 大陆种群的所有地区,因为该方法很容易复制和转移。GNP 的 NE 部分可以在未来几年为 the Scops Owl 实现更好的 C&B 条件(适用性可能增加 36%)。预测表明,应该在丘陵 GNP 的 N、NE 和 E 部分实施更多的努力和行动,以保护研究区的角鸮。因此,我们的结果不仅适用于该保护区的决策者,而且适用于 Scops Owl 大陆种群的所有地区,因为该方法很容易复制和转移。
