栖息地丧失、栖息地碎片化和栖息地退化是欧洲和世界其他地区哺乳动物面临的最大威胁。尽管有大量的文献存在，但到目前为止还没有全面的综述或综合，这可能会减缓科学进步并阻碍保护工作。2.这项研究的目的是了解栖息地丧失和片断化对欧洲陆生哺乳动物空间分布的影响的研究是否取得了进展，以及在什么方向取得了进展。首先，我们围绕11个关键点进行了总体综合。这一逐点分析的目的是查明现有文献中的趋势、知识差距和任何重大偏见，并突出迄今已采用的不同方法的优点和不足。其次，我们遵循特定物种的系统方法：对于每个物种，我们综合关键结果。3.我们的结果表明，实质性进展受到阻碍的原因有几个，包括：短时间的小规模实地研究占主导地位，以及普遍缺乏对以下因素的控制：(I)混淆变量；(Ii)空间自相关；(Iii)虚假缺席。此外，尽管研究的数量相对较多，但很少有理论研究，更少的是荟萃分析。缺乏荟萃分析很可能是因为出版物中包含的关键细节很少，如模型参数或关于景观背景的信息(如剩余森林覆盖率)。
Habitat loss, habitat fragmentation and habitat degradation are the greatest threats to mammals in Europe and the rest of the world. Despite the fact that extensive literature exists, no comprehensive review or synthesis is available to date and this may slow down scientific progress and hamper conservation efforts. 2. The goal of this study is to understand if and in what direction progress has been made in the study of the effects of habitat loss and fragmentation on the spatial distribution of European terrestrial mammals. Firstly, we carry out a general synthesis which is structured around 11 key points. The aim of this point-by-point analysis is to identify trends, knowledge gaps and any significant bias in the available literature, and to highlight strengths and shortfalls of the different approaches which have to date been applied. Secondly, we follow a species-specific systematic approach: for each species, we synthesise key results. 3. Our results show how substantial progress has been hampered for several reasons including: a large predominance of small-scale field studies of short duration, and a generalised lack of control of: (i) confounding variables; (ii) spatial autocorrelation; and (iii) false absences. Also, despite the relatively high number of studies, few were theoretical studies and even fewer were meta-analyses. The lack of meta-analyses is likely to be due to the small amount of crucial details included in the publications, such as model parameters or information on the landscape context (such as the amount of residual forest cover).
