Necrobiome Succession in Muscle Tissue as a Potential Indicator of Postmortem Interval
… showed patterns relating to time, temperature, accumulated degree-days, bacterial markers for sample site location, bacterial markers for donor identification, and as a whole, potential indications of postmortem interval.</p>

Defining Postmortem Changes in Western Montana: The Effects of Climate and Environment on the Rate and Sequence of Decomposition Using Pig (Sus scrofa) Cadavers
… variables. The popular method of calculating accumulated degree days (ADD) to estimate time since death was tested and found to consistently underestimate the actual day of death, indicating that without alteration, this method should not be relied on for remains that have decomposed in …

Aspect of the biology of sod webworms (Lepidoptera: Pyralidae: Crambinae) and turfgrass inhabiting insects of Virginia
… except Parapediasia teterrella (Zincken). Accumulated degree-days can predict an additional years worth of occurrence of Microcrambus elegans (Clemens), Crambus lagueatellus Clemens, Pediasia trisecta (Walker) , and Agriphila ruricolella (Zeller), in the Appalachian region of Virginia. …

The Postmortem Interval: A Systematic Study of Pig Decomposition in West Central Montana
… and elsewhere in the United States. The use of accumulated degree-days (ADD) to estimate the postmortem interval reveals accurate time since death estimations and consistency with previous PMI studies despite significant differences in climate and weather patterns. This project is the first of a …

AVIAN SCAVENGING, MUMMIFICATION, AND VARIABLE MICRO-ENVIRONMENTS AS FACTORS AFFECTING THE DECOMPOSITION PROCESS IN WESTERN MONTANA
… of three pigs over the course of one year and 19 days. The data from this study will be compared and contrasted to studies that have occurred elsewhere. A full understanding of the postmortem changes and rate of soft tissue decomposition in this area will help forensic anthropologists better …

Physical and chemical analysis of pig carcass decomposition in a fine sand
… system and decomposition scores were related to accumulated degree days (ADD). Overall, the ADD values were significantly different for the two groups of carcasses; however, the ADD values for the onset of each score demonstrated more similarity between groups. Decomposition scoring results also …

The analysis of the entomological and chemical decomposition of human remains to ultimately assess the viability of the domestic pig as a substitute in forensic applications
… conditions were monitored as well as the accumulated degree days (ADD), rates of decomposition, primary dipteran colonizers, and volatile organic compound (VOC) production. Domestic pigs in Oshawa, Ontario, had rates of decomposition that were highly alike. Rates of insect colonization …

The effect of clothing on decomposition and scavenging in two forensically significant habitats in Cape Town, South Africa
… data demonstrate the potential of utilising accumulated degree days and moisture content to estimate the postmortem interval. The combined results advocate using single-clothed carcasses deployed across multiple seasonal trials in forensically significant locations to produce data that can be …

Life history and secondary production of Cheumatopsyche spp. in a small Appalachian stream with two different land uses on its watershed
… agricultural activities. There was higher annual accumulated degree days, and stream substrate particles were mostly mid and coarse gravel. The downstream section was surrounded by forest, with little evidence of human activities and disturbance and with a more diverse distribution of particle …

Estimation of Post-Mortem Interval Using Decomposition Scales for Hanging Bodies
… of a body can be used, in conjunction with accumulated degree days (ADD), to provide an estimate of the post-mortem interval (PMI). PMI estimations are important in aiding police to narrow down the possible identity of a body, and to include or exclude suspects, and also to establish the …

Partitioning along reproductive niche dimensions in sympatric New Zealand freshwater bivalve species
… timing identified key thermal cues (particularly accumulated degree days) associated with brooding onset and glochidia maturation in both species. The importance of water temperature suggests that changes in climatic conditions have the potential to cause negative effects on both species by …
