Decomposition studies were conducted at two sites on the Island of Oahu, Hawaii, to compare patterns of decomposition and arthropod invasion in intertidal and adjacent terrestrial habitats. The animal model used was the domestic pig. One site was on Coconut Island in Kaneohe Bay on the northeast side of Oahu, and the second was conducted in an anchialine pool located at Barber's Point Naval Air Station on the southwest shore of Oahu. At both sites, the terrestrial animal decomposed in a manner similar to what has been observed in previous studies in terrestrial habitats on the island of Oahu. Rate of biomass depletion was slower in both intertidal studies, and decomposition was primarily due to tide and wave activity and bacterial decomposition. No permanent colonization of carcasses by insects was seen for the intertidal carcass at Coconut Island. At the anchialine pool at Barber's Point Naval Air Station, Diptera larvae were responsible for biomass removal until the carcass was reduced below the water line and, from that point on, bacterial action was the means of decomposition. Marine and terrestrial scavengers were present at both sites although their impact on decomposition was negligible. Five stages of decomposition were recognized for the intertidal sites: fresh, buoyant/floating, deterioration/disintegration, buoyant remains, and scattered skeletal.
在夏威夷瓦胡岛的两个地点进行了分解研究，以比较潮间带和相邻陆地栖息地的分解模式和节肢动物入侵情况。使用的动物模型是家猪。一个地点位于瓦胡岛东北侧卡内奥赫湾的椰子岛，另一个地点在位于瓦胡岛西南海岸的巴伯斯角海军航空站的一个沿岸咸水湖。在这两个地点，陆生动物的分解方式与之前在瓦胡岛陆地栖息地的研究中所观察到的相似。在两个潮间带研究中，生物量消耗速度较慢，分解主要是由于潮汐和波浪活动以及细菌分解。在椰子岛的潮间带尸体上，没有观察到昆虫对尸体的永久定殖。在巴伯斯角海军航空站的沿岸咸水湖，双翅目幼虫负责去除生物量，直到尸体降至水线以下，从那时起，细菌作用成为分解的方式。两个地点都有海洋和陆地食腐动物，尽管它们对分解的影响可以忽略不计。潮间带地点的分解分为五个阶段：新鲜、漂浮、腐烂/解体、漂浮残骸和散落骨骼。
