There seems to be a limited colonisation of cadavers at the scene of the death, despite the ubiquity of necrophagous species in the area. We performed a survey on the diversity and temporal pattern of colonization of beetles on pig carcasses in a fragment of dry forest in northeastern Brazil. With the exception of biomass loss by the emigration of maggots on days 4 and 5, neither repeated weighing of the carcasses nor repeated weighing and faunal sampling of the carcasses statistically affected the rate of biomass loss.
Additionally, by comparing fauna around the body with fauna found on the body one can obtain information if the corpse was moved after death. Forensic entomologists use blow fly development to estimate a postmortem interval. After analyzing some existing network forensics methods to identify common shortcomings, we propose in this paper a new network forensics method that uses a combination of network vulnerability and network evidence graph.
