-埋葬甲虫找到并埋葬小型脊椎动物尸体，并将其形成为幼虫的育雏球。通过将死老鼠放置在北卡罗来纳州山麓的森林地面上，研究人员通过埋葬甲虫在与脊椎动物食腐动物和其他食腐无脊椎动物的尸体竞争中胜出的能力。从 5 月到 9 月（1984-1985），甲虫在第一天晚上只发现了大约 25% 的尸体。 1984 年仲夏，甲虫埋葬的尸体中只有不到一半能产卵。虽然三种埋葬甲虫（Nicrophorus orbicollis Say、N. tomentosus Weber 和 N. pustulatus Herschel）被用大量腐肉作为诱饵的陷阱捕获，但只有前两种对老鼠尸体有活性。与北美北部栖息地的早期研究相比，东南部林地中埋藏甲虫的数量较少、多样性较低，而且也不那么成功。据推测，与温度相关的竞争是埋藏甲虫成功的一个重要决定因素。
-Burying beetles locate and bury small vertebrate carcasses which they form into brood balls for their young. The ability of burying beetles to outcompete vertebrate scavengers and other carrion-feeding invertebrates for carcasses was investigated by placing dead mice on the forest floor in the North Carolina piedmont. From May to September (1984-1985), beetles discovered only about 25% of carcasses on the 1st night. During midsummer of 1984, less than one-half of the carcasses that beetles managed to bury produced broods. Although three species of burying beetles (Nicrophorus orbicollis Say, N. tomentosus Weber and N. pustulatus Herschel) were caught in pitfall traps baited with a large quantity of carrion, only the first two were active on mouse carcasses. Compared with earlier studies in northern habitats of North America, burying beetles are less abundant, less diverse and not as successful in southeastern woodlands. Temperature-dependent competition is hypothesized to be an important determinant of burying beetle success.
