Abstract

We assessed the diet composition of wolves inhabiting Notecka Forest (ca 1400 km2) in western Poland based on the analysis of scats (n = 261) collected in 2008–2021. The study revealed that wolves in this large forest tract, consisting mainly of pine monocultures, consumed primarily wild ungulates (95.2% of consumed biomass). The roe deer was the essential food item (47.8%), followed by the red deer Cervus elaphus (25.1%) and the wild boar Sus scrofa) (18.4%). Wolves supplemented their diet with medium‐sized wild mammals, mainly the European hare Lepus europaeus (2.8%) and the Eurasian beaver Castor fiber (1.9%). The food niche was narrow (B = 1.1), and there was no difference in food composition between the spring–summer and autumn–winter seasons. We emphasize the significance of the smallest European wild ruminant, roe deer, in the diet of wolves inhabiting Central European Plains.

波兰西部诺特卡森林中狼的食谱

我们根据 2008-2021 年收集的狼粪便（n = 261）分析，评估了栖息在波兰西部诺特卡森林（约 1400 平方公里）的狼的食物组成。研究表明，在这片主要由松树单植林组成的大片森林中，狼主要食用野生有蹄类动物（占消耗生物量的 95.2%）。狍子是主要食物（47.8%），其次是马鹿（25.1%）和野猪（18.4%）。狼以中型野生哺乳动物为辅，主要是欧洲野兔（2.8%）和欧亚海狸（1.9%）。食物生态位很窄（B = 1.1），春夏季和秋冬季的食物组成没有差异。我们强调欧洲最小的野生反刍动物狍子在中欧平原狼群食物中的重要性。

期刊介绍： WILDLIFE BIOLOGY is a high-quality scientific forum directing concise and up-to-date information to scientists, administrators, wildlife managers and conservationists. The journal encourages and welcomes original papers, short communications and reviews written in English from throughout the world. The journal accepts theoretical, empirical, and practical articles of high standard from all areas of wildlife science with the primary task of creating the scientific basis for the enhancement of wildlife management practices. Our concept of ''wildlife'' mainly includes mammal and bird species, but studies on other species or phenomena relevant to wildlife management are also of great interest. We adopt a broad concept of wildlife management, including all structures and actions with the purpose of conservation, sustainable use, and/or control of wildlife and its habitats, in order to safeguard sustainable relationships between wildlife and other human interests.
