Since 1995, the Alpine chamois () population of the Dolomites has been affected by sarcoptic mange with considerable management concerns. In this study, 15 years (2006-2020) of passive surveillance and demographic data were analyzed in order to describe a mange outbreak. Furthermore, an enhanced passive surveillance protocol was implemented in order to evaluate the efficiency of ordinary vs. enhanced surveillance protocol in identifying dead chamois in the field and in reaching a correct diagnosis. Our results confirm the role of mange as a determining factor for chamois mortality, while stressing the importance of a wider view on the factors affecting population dynamics. The enhanced passive surveillance protocol increased the probability of carcass retrieval and identification of the cause of death; however, its adoption may be too costly if applied for long periods on a wide scale. Passive surveillance, in both ordinary and enhanced surveillance protocol, should encompass the use of other strategies in the future to study the eco-epidemiology of the disease in wild Caprinae.
自1995年以来，多洛米蒂山的高山瞪羚（）种群受到疥螨病的影响，引发了相当多的管理问题。在本研究中，分析了15年（2006 - 2020年）的被动监测和种群数据，以描述疥螨病的爆发情况。此外，实施了强化被动监测方案，以评估常规监测方案与强化监测方案在野外识别死亡瞪羚以及做出正确诊断方面的效率。我们的结果证实了疥螨病是瞪羚死亡的决定性因素，同时强调了全面看待影响种群动态因素的重要性。强化被动监测方案提高了找到尸体并确定死因的概率；然而，如果长期大规模应用，其成本可能过高。在未来，无论是常规监测方案还是强化监测方案中的被动监测，都应采用其他策略来研究野生山羊亚科动物疾病的生态流行病学。
