Abstract

Wolves are opportunistic generalists that can respond quickly to new and unique food sources. Wolves in some ecosystems will consume berries and other fruits when they are abundant and available; however, many aspects of this behavior remain unknown. In the Greater Voyageurs Ecosystem (GVE), Minnesota, USA, wolves consistently consume berries, particularly blueberries, when they are available. We deployed remote cameras in blueberry patches to record wolves foraging on berries over several years. We captured footage of wolves of all age classes, social statuses, and sex foraging on blueberries alone or with other wolves. Our observations indicate berry consumption by wolves is a widespread behavior in the GVE and likely in similar southern boreal ecosystems. We hope our work spurs researchers across wolf range to examine whether berry consumption by wolves is a widespread and ubiquitous behavior for wolves.

狼觅食浆果很可能是北方南部生态系统中的一种普遍行为
狼是一种机会主义通食动物,能够对新的和独特的食物来源迅速做出反应。某些生态系统中的狼会在浆果和其他水果丰富且可获得时食用它们;然而,这种行为的许多方面仍不为人知。在美国明尼苏达州的大沃亚吉尔斯生态系统(GVE)中,当有浆果,尤其是蓝莓时,狼会持续食用。我们在蓝莓地部署了遥控摄像机,以记录狼在过去几年中觅食浆果的情况。我们捕捉到了不同年龄段、社会地位和性别的狼单独或与其他狼一起觅食蓝莓的镜头。我们的观察结果表明,狼吃浆果的行为在 GVE 很普遍,而且很可能在类似的北方南部生态系统中也很普遍。我们希望我们的工作能激励整个狼群分布区的研究人员研究狼群食用浆果是否是一种普遍存在的行为。

期刊介绍: The scope of Ecosphere is as broad as the science of ecology itself. The journal welcomes submissions from all sub-disciplines of ecological science, as well as interdisciplinary studies relating to ecology. The journal''s goal is to provide a rapid-publication, online-only, open-access alternative to ESA''s other journals, while maintaining the rigorous standards of peer review for which ESA publications are renowned.
