1980年至1984年期间，在澳大利亚昆士兰州米奥拉斯普林斯的红树林中，对碎叶机在实验室条件下处理和撕碎树叶的方式进行了调查。对红指蟹在退潮时的行为进行的野外观察显示，该物种的大部分时间都在泥泞中觅食。红指蟹吃掉的红树林树叶，或将它们拖入洞穴或中空的原木中。通过它们的摄食活动，蟹类(红指蟹、门腹蟹、李氏螺虫、斜纹夜蛾、变色细尾蟹、乳突拟甲藻、软腹蟹)、等足目动物(翼外丝虫、弯头腹足类)两足类(兰花、梅里塔普)和一种头盖类多毛类(头盖型多毛类)将整个红树林的叶子分解成小颗粒。碎叶机分解树叶的方式会影响环境中颗粒有机物(POM)的大小和组成。碎叶机排放的POM从32到1171μm不等。这个大小范围的POM存在于38种以泥土为食的无脊椎动物的肠道中，这表明它们依赖碎叶机产生的植物碎屑作为食物来源。因此，碎叶机构成了红树林海洋食物网中的主要环节。
The way leaf shredders handle and shred leaves under laboratory conditions and in the mangrove forest at Myora Springs, Queensland, Australia, was investigated during the period 1980 to 1984. Field observations on the behaviour of the crabSesarma erythrodactyladuring low tide revealed that this species spends most of its time foraging over mud.S. erythrodactylaeats mangrove leaves where they fall or drags them into burrows or hollow logs. Through their feeding activities, crabs (S. erythrodactyla, Metopograpsus frontalis, Helice leachii, Clistocoeloma merguiensis, Leptograpsus variegatus, Paragrapsus laevis, Ilyograpsus paludicula), isopods (Exospaeroma alata, Campaecopiasp.) amphipods (Orchestiasp.,Melitasp.), and a capitellid polychaete (Capitellidessp.), break down whole mangrove leaves into small particles. The way in which a leaf is broken down by leaf-shredders influences the size and composition of the particulate organic matter (POM) in the environment. The POM egested by leaf-shredders varies from 32 to 1171 μm. POM in this size range occurs in the guts of 38 invertebrate species which feed on mud, suggesting that they depend on the plant detritus produced by leafshredders as a source of food. Leaf-shredders therefore constitute a primary link in the marine food web of mangrove forests.
