The Time between Death and the Discovery of the Corpse Assignment

The Time between Death and the Discovery of the Corpse - Assignment Example This highlighted the aim of the study to show the importance of considering the effects of larval crowding that could cause PMI errors during casework. It was found out that increased larval crowding resulted in faster development of C. vomitoria and the size of C. vomitoria that could cause overestimation and underestimation of PMI respectively if not accounted for during casework. The major limitation of this research is that the study only explored development during larval stages. This means that further investigations are needed before making direct comparisons with the results. Moreover, comparison with other studies was difficult because the muscle used in each experiment had a different origin and was likely to cause variation in the results. The consideration of space available to larvae within a culture affects competitive interactions would be required. The research had several strengths while conducting the research. The researchers ensured that food was always in excess so that competitive effects could be ruled out. They also reared the cultures in different pig tissue enabling them to determine the development rate at different larval densities in cultures reared in the brain, liver, and muscle while keeping the experimental conditions identical. The effects of larval crowding at three intervals on each of the three tissues were observed for the greatest changes in body tissues. It was found out that the brain was the least nourishing and due to lower protein levels and higher water content, there was rapid consumption compared to the other tissues. In conclusion, the research was justified because it effectively gave light to how overcrowding during larval stages of development resulted in a competitive feeding environment, therefore, affecting size, development rate, and survival.
