欧洲兔是伊比利亚半岛地中海生态系统的特有物种，是那里的关键物种。近年来，由于栖息地变化和病毒性疾病等几个因素，它的数量有所下降。与此同时，还采取了纠正措施，包括在人口密度较低的地区利用其他地理区域的兔子重新放养兔子。在这项研究中，我们评估了重新放养对多纳纳国家公园本地兔子种群动态的影响。作为多纳纳生物站(ESPN-EBD-CSIC)自然过程监测计划的一部分，在2005-2015年春季和夏末，沿着兔子种群栖息地的六个固定横断面进行了兔子普查。为了考虑到重新放养的兔子数量，多纳纳自然区的年度报告和LIFE项目的Lynx团队提供的数据被纳入研究。在2005-2015年间，总共有52336只来自西安达卢西亚不同地区的兔子被释放到多纳纳生物圈保护区。然而，兔子的数量经历了显著的下降，尤其是在2013年和2015年，一些地区的降幅高达80%。这些结果表明，集约化放养并没有增加本地兔的数量。文中还讨论了放生兔子对多纳纳种群动态的影响。(C)《2019年》，爱思唯尔出版。
The European rabbit (Oryctolagus cuniculus) is endemic to Mediterranean ecosystems in the Iberian Peninsula, where it is a key species. In recent years its populations have declined due to several factors including habitat transformation and viral diseases. At the same time, corrective measures including population restocking in areas with low population densities using rabbits from other geographical areas have been performed. In this study we evaluate the impact restocking has had on the population dynamics of native rabbits in the Donana National Park. As part of the natural processes monitoring program carried out in the Donana Biological Station (ESPN-EBD-CSIC), rabbit censuses were conducted in spring and late summer in 2005-2015 at dusk and at night along six fixed transects in habitats harbouring rabbit populations.In order to take into account restocked rabbit numbers, annual reports from the Donana Natural Area and data provided by the Lynx team of the LIFE project were incorporated into the study. In all, 52 336 rabbits from different parts of western Andalusia were released in the Donana Biosphere Reserve in 2005-2015. Yet, rabbit populations underwent significant declines, above all in 2013 and 2015, with decreases in some areas of up to 80%. These results show intensive rabbit restocking did not increase the native rabbit populations numbers. The impact of the release of rabbits on the population dynamics of the species in Donana is discussed. (C) 2019 Published by Elsevier B.V.
