Abstract

Abstract Canis lupus (Gray Wolf or Wolf) have killed subordinate canids that scavenge on Wolf-killed prey, but little evidence is available for antagonistic behavior of Wolves toward other canids at interspecific den sites. We investigated clusters of locations from a global positioning system (GPS)collared male Wolf, translocated to Isle Royale National Park, MI, on 23 March 2019. On 17 May 2019, we investigated a GPS cluster of the Wolf and observed 3 Vulpes vulpes (Red Fox) kit carcasses at an excavated Red Fox den site. We report details from this event and evidence for interspecific aggression and implications for Wolf–Red Fox interactions. To our knowledge, this represents the first reported killing of Red Fox kits at their den by a Wolf. Limited reports of interspecific killings by Wolves of Red Foxes suggests this interaction was opportunistic and rare.

密歇根州皇家岛国家公园犬只狼疮（灰狼）在巢穴中对Vulpes Vulpes（Red Fox）试剂盒的种间杀死

摘要犬类狼疮（灰狼或狼）已经杀死了以狼杀死的猎物为食的附属犬科动物，但几乎没有证据表明狼在种间巢穴对其他犬科动物有拮抗行为。2019年3月23日，我们调查了一只带全球定位系统（GPS）项圈的雄性狼的集群位置，该狼被转移到密歇根州皇家岛国家公园。2019年5月17日，我们调查了一个狼的GPS集群，并在一个挖掘的红狐巢穴中观察到了3具Vulpes Vulpes（红狐）工具包尸体。我们报道了这一事件的细节，以及物种间攻击的证据，以及对狼-红狐互动的影响。据我们所知，这是第一次有报道称红狐装备在巢穴中被狼杀死。关于红狐狸之狼进行物种间杀戮的有限报道表明，这种互动是机会主义的，而且很罕见。

期刊介绍： The Northeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the northeastern portion of North America, roughly bounded from Virginia to Missouri, north to Minnesota and Nunavut, east to Newfoundland, and south back to Virginia. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion. The journal welcomes manuscripts based on observations and research focused on the biology of terrestrial, freshwater, and marine organisms and communities as it relates to their life histories and their function within, use of, and adaptation to the environment and the habitats in which they are found, as well as on the ecology and conservation of species and habitats. Such studies may encompass measurements, surveys, and/or experiments in the field, under lab conditions, or utilizing museum and herbarium specimens. Subject areas include, but are not limited to, anatomy, behavior, biogeography, biology, conservation, evolution, ecology, genetics, parasitology, physiology, population biology, and taxonomy. Strict lab, modeling, and simulation studies on natural history aspects of the region, without any field component, will be considered for publication as long as the research has direct and clear significance to field naturalists and the manuscript discusses these implications.
