在美国马萨诸塞州中部的 2 个封闭的笼养蛋鸡舍中，在为期 16 周的粪便积累周期（5 月至 9 月）中对与家禽粪便相关的节肢动物的演替进行了监测。 Coproica hirtula（双翅目：Sphaeroceridae）和螨虫是最先定居的节肢动物，其次是Macrocheles muscaedomesticae（螨虫：Macrochelidae）和Carcinops pumilio（鞘翅目：Histeridae）。大螯虾丰度在清理后 7 周达到峰值，而食蟹成虫的数量在整个周期中不断增加。 Carcinops性别比例在周期早期显着偏向雄性（1.5:1），在中间几周接近1:1，并在后期几周再次显着偏向雄性（1.9:1）。在幼鱼数量达到峰值之后，出现了明显较小的成鱼。在捕食者丰度高峰期间收集的成年甲虫的卵巢明显低于来自低密度种群的甲虫发育程度。
Succession of arthropods associated with poultry manure was monitored in 2 enclosed caged layer houses throughout a 16-wk manure accumulation cycle (May–Sept.) in central Massachusetts, USA. Coproica hirtula (Diptera: Sphaeroceridae) and acarid mites were the first arthropods to become established, followed by Macrocheles muscaedomesticae (Acari: Macrochelidae) and Carcinops pumilio (Coleoptera: Histeridae). Macrocheles abundance peaked at 7 wk post-cleanout, while Carcinops adults increased in number throughout the cycle. Carcinops sex ratios were significantly male-biased (1.5:1) early in the cycle, approached 1:1 in the middle weeks, and were significantly male-biased again (1.9:1) in later weeks. Significantly smaller Carcinops adults appeared following peaks of numbers of immatures. Adult beetles collected during peaks of predator abundance had ovaries significantly less developed than those from lower-density populations.
