Grassland systems constitute a significant portion of the land area in the United States and as a result harbors significant arthropod biodiversity. During this time of biodiversity loss around the world, bioinventories of ecologically important habitats serve as important indicators for the effectiveness of conservation efforts. We conducted a bioinventory of the foliar, soil, and dung arthropod communities in 10 cattle pastures located in the southeastern United States during the 2018 grazing season. In sum, 126,251 arthropod specimens were collected. From the foliar community, 13 arthropod orders were observed, with the greatest species richness found in Hymenoptera, Diptera, and Hemiptera. The soil-dwelling arthropod community contained 18 orders. The three orders comprising the highest species richness were Coleoptera, Diptera, and Hymenoptera. Lastly, 12 arthropod orders were collected from cattle dung, with the greatest species richness found in Coleoptera, Diptera, and Hymenoptera. Herbivores were the most abundant functional guild found in the foliar community, and predators were most abundant in the soil and dung communities. Arthropod pests constituted a small portion of the pasture arthropod communities, with 1.01%, 0.34%, and 0.46% pests found in the foliar, soil, and dung communities, respectively. While bioinventories demand considerable time, energy, and resources to accomplish, the information from these inventories has many uses for conservation efforts, land management recommendations, and the direction of climate change science.

美国东南部牧场的叶、土壤和粪便节肢动物群落清单

草地系统构成了美国土地面积的很大一部分,因此拥有重要的节肢动物生物多样性。在世界各地生物多样性丧失的这段时间里,具有重要生态意义的栖息地的生物清单是保护工作有效性的重要指标。我们在 2018 年放牧季节对位于美国东南部的 10 个牛牧场的叶、土壤和粪便节肢动物群落进行了生物清查。总之,收集了 126,251 个节肢动物标本。从叶面群落中,观察到 13 个节肢动物目,其中膜翅目、双翅目和半翅目物种丰富度最高。土栖节肢动物群落包含 18 个目。构成物种丰富度最高的三个目是鞘翅目、双翅目、和膜翅目。最后,从牛粪中收集了 12 个节肢动物目,其中鞘翅目、双翅目和膜翅目中的物种丰富度最高。草食动物是叶面群落中功能最丰富的群落,而食肉动物在土壤和粪便群落中最为丰富。节肢动物害虫构成了牧场节肢动物群落的一小部分,分别在叶、土壤和粪便群落中发现了 1.01%、0.34% 和 0.46% 的害虫。虽然完成生物清单需要大量的时间、精力和资源,但这些清单中的信息在保护工作、土地管理建议和气候变化科学方向上有许多用途。和膜翅目。草食动物是叶面群落中功能最丰富的群落,而食肉动物在土壤和粪便群落中最为丰富。节肢动物害虫构成了牧场节肢动物群落的一小部分,分别在叶、土壤和粪便群落中发现了 1.01%、0.34% 和 0.46% 的害虫。虽然完成生物清单需要大量的时间、精力和资源,但这些清单中的信息在保护工作、土地管理建议和气候变化科学方向上有许多用途。和膜翅目。草食动物是叶面群落中功能最丰富的群落,而食肉动物在土壤和粪便群落中最为丰富。节肢动物害虫构成了牧场节肢动物群落的一小部分,分别在叶、土壤和粪便群落中发现了 1.01%、0.34% 和 0.46% 的害虫。虽然完成生物清单需要大量的时间、精力和资源,但这些清单中的信息在保护工作、土地管理建议和气候变化科学方向上有许多用途。分别在叶面、土壤和粪便群落中发现 46% 的害虫。虽然完成生物清单需要大量的时间、精力和资源,但这些清单中的信息在保护工作、土地管理建议和气候变化科学方向上有许多用途。分别在叶面、土壤和粪便群落中发现 46% 的害虫。虽然完成生物清单需要大量的时间、精力和资源,但这些清单中的信息在保护工作、土地管理建议和气候变化科学方向上有许多用途。
