Connor notes that fly maggots are picky eaters. Ultimately, though, decomposition is beneficial for the ecosystem the microbial biomass within the cadaver decomposition island is greater than in other nearby areas; nematode worms also become more abundant, and plant life more diverse.

For more than a year after death, corpses move around "significantly", and this finding could be important for forensic investigations. Different groups of animals find the corpse attractive at different stages of decomposition and the resultant change in the animal community is called a succession. Various compounds contribute to the potent odour of a decomposing body, including cadaverine, putrescine, skatole, indole, and a variety of sulphur-containing compounds. Skeletonised human remains near the entrance to the Forensic Anthropology Center at Texas State University in San Marcos, TX. For instance, detecting DNA sequences known to be unique to a particular organism or soil type in a cadaver could help crime scene investigators link the body of a murder victim to a particular geographical location, or narrow down their search for clues even further, perhaps to a specific field within a given area.
