These modifications change the rate of decomposition, the patterns of insect succession, and the context of associations, thus altering estimations of time-since-death. A controlled feeding study with captive wolves and road-killed deer is pertinent to understanding canid scavenging and how scavenging may alter postmortem changes. During feeding, the wolves commonly dismember and devour the deer in a predictable sequence. Although there are some variations in the usual sequence, the carcass is always moved, and skeletal elements are separated, diminished in size and scattered. Scavenging must, therefore, be considered in estimating time since death. (Author abstract)
