Abstract

The Reeves’ muntjac Muntiacus reevesi is an ungulate native to China and Taiwan that has been released into the wild in several continental European countries and the United Kingdom. We present recent records of the species in mainland France. We also investigated the dispersal rate and density of the established population in the Centre-Val de Loire region. The number of observations of M. reevesi was low in the period 2008–2016, increased sharply until 2019 and then decreased until 2023. From a comparison between the distribution in 2008–2012 and 2013–2017, the dispersal rate was estimated at an average of 3.2 km/year, and 7.6 km/year between 2013–2017 and 2018–2023. Based on a camera trap protocol, the population density was assumed to be very low in forested areas but estimated with a lack of robustness due to a single observation. Further efforts must be made to better assess the risk of an increase in the wild population of Reeves’ muntjac in the Centre-Val de Loire region. To prevent potential impacts, rapid control measures can be put in place in the large area (10,800 km2) where muntjacs are now rapidly spreading.
里维斯麂(Muntiacus reevesi)(Ogilby,1839 年)在法国的分布现状
里维斯麂(Muntiacus reevesi)是一种原产于中国大陆和台湾地区的有蹄类动物,已在欧洲大陆多个国家和英国被放归野外。我们介绍了该物种在法国大陆的最新记录。我们还调查了卢瓦尔河中游地区已建立种群的扩散率和密度。2008-2016年期间,M. reevesi的观测数量较少,直到2019年才急剧增加,然后直到2023年才有所减少。通过比较2008-2012年和2013-2017年的分布情况,估计其扩散速度平均为每年3.2公里,2013-2017年和2018-2023年之间平均为每年7.6公里。根据相机陷阱协议,假定森林地区的种群密度很低,但由于仅有一次观测,估算结果缺乏稳健性。必须进一步努力,更好地评估卢瓦尔河中游地区里维斯麂野生种群数量增加的风险。为了防止潜在的影响,可以在麂目前迅速扩散的大片区域(10800 平方公里)采取快速控制措施。

期刊介绍: Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
