Abstract

In Germany, wolves live in a human-dominated landscape. The return of the wolf to Germany more than 20 years ago is a prime example of successful nature conservation; however, it has also led to conflict due to the high degree of landscape fragmentation and the feeding habits of the wolf. Here, the wolf diet composition was studied based on an analysis of 11,225 scats. Wolves in Germany mainly feed on wild ungulates, which comprise more than 94% of their diet. The predominant species are roe deer and wild boar, whereby in most territories roe deer dominate the diet composition. Depending on availability, red deer and fallow deer may also make up a high proportion of the diet. Seasonal and territorial variation in diet composition has been noted even in directly neighboring territories. Wolves preferentially hunt juveniles of the main prey species. With the exception of the mouflon, which has all but disappeared locally, no other ungulate species has vanished from the wolf’s diet. This study provides an overview of the varied diet of wolves in Germany since recolonization more than 20 years ago.

德国人类活动景观中狼（Canis lupus）的进食动态：20 年调查

在德国，狼生活在以人类为主的景观中。20 多年前，狼重返德国，这是自然保护的一个成功范例；然而，由于景观的高度破碎化和狼的觅食习性，这也导致了冲突。在这里，我们根据对 11,225 块狼粪的分析，对狼的食物组成进行了研究。德国的狼主要以野生蹄类动物为食，占其食物的 94% 以上。主要种类是狍子和野猪，在大多数地区，狍子是狼的主要食物。根据供应情况，红鹿和野鹿也可能在食物中占很大比例。即使在直接相邻的领地，狼的食物组成也会随季节和领地而变化。狼喜欢捕食主要猎物物种的幼崽。除了在当地几乎已经消失的褐马鸡之外，狼的食物中没有其他有蹄类动物物种消失。本研究概述了自 20 多年前狼在德国重新定居以来，狼的各种食谱。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
