Postmortem Interval (Pmi) Determination At Three Biogeoclimatic Zones In Southwest Colorado, Maria T. Allaire

LSU Master's Theses

Three pig (Sus scrofa L.) carcasses were exposed during the summer in three different biogeoclimatic zones ranging in elevations from 6,700 to 11,100 feet in order to determine the rates of carrion decomposition and arthropod succession patterns on carrion in southwest Colorado. The carcasses were exposed in three scenarios: sun-exposed, shaded, and sun-exposed/shaded. Of the total 63 taxa collected, thirty species overlapped between two biogeoclimatic zones. A strong elevational preference is indicated for the Sarcophagidae taxon. A previously undescribed Boettcheria species was collected at 11,100 feet. The rates of decomposition lengthened as elevation increased due to a prolongation of the …
