A Global Study of Forensically Significant Calliphorids: Implications for Identification
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by South East Academic Libraries System (SEALS) A global study of forensically significant calliphorids: Implications for identification M.L. Harveya, S. Gaudieria, M.H. Villet and I.R. Dadoura Abstract A proliferation of molecular studies of the forensically significant Calliphoridae in the last decade has seen molecule-based identification of immature and damaged specimens become a routine complement to traditional morphological identification as a preliminary to the accurate estimation of post-mortem intervals (PMI), which depends on the use of species-specific developmental data. Published molecular studies have tended to focus on generating data for geographically localised communities of species of importance, which has limited the consideration of intraspecific variation in species of global distribution. This study used phylogenetic analysis to assess the species status of 27 forensically important calliphorid species based on 1167 base pairs of the COI gene of 119 specimens from 22 countries, and confirmed the utility of the COI gene in identifying most species. The species Lucilia cuprina, Chrysomya megacephala, Ch. saffranea, Ch. albifrontalis and Calliphora stygia were unable to be monophyletically resolved based on these data. Identification of phylogenetically young species will require a faster-evolving molecular marker, but most species could be unambiguously characterised by sampling relatively few conspecific individuals if they were from distant localities. Intraspecific geographical variation was observed within Ch. rufifacies and L. cuprina, and is discussed with reference to unrecognised species. 1. Introduction The advent of DNA-based identification techniques for use in forensic entomology in 1994 [1] saw the beginning of a proliferation of molecular studies into the forensically important Calliphoridae. -
The Evolution of Myiasis in Blowflies (Calliphoridae)
International Journal for Parasitology 33 (2003) 1105–1113 www.parasitology-online.com The evolution of myiasis in blowflies (Calliphoridae) Jamie R. Stevens* School of Biological Sciences, University of Exeter, Prince of Wales Road, Exeter EX4 4PS, UK Received 31 March 2003; received in revised form 8 May 2003; accepted 23 May 2003 Abstract Blowflies (Calliphoridae) are characterised by the ability of their larvae to develop in animal flesh. Where the host is a living vertebrate, such parasitism by dipterous larvae is known as myiasis. However, the evolutionary origins of the myiasis habit in the Calliphoridae, a family which includes the blowflies and screwworm flies, remain unclear. Species associated with an ectoparasitic lifestyle can be divided generally into three groups based on their larval feeding habits: saprophagy, facultative ectoparasitism, and obligate parasitism, and it has been proposed that this functional division may reflect the progressive evolution of parasitism in the Calliphoridae. In order to evaluate this hypothesis, phylogenetic analysis of 32 blowfly species displaying a range of forms of ectoparasitism from key subfamilies, i.e. Calliphorinae, Luciliinae, Chrysomyinae, Auchmeromyiinae and Polleniinae, was undertaken using likelihood and parsimony methods. Phylogenies were constructed from the nuclear 28S large subunit ribosomal RNA gene (28S rRNA), sequenced from each of the 32 calliphorid species, together with suitable outgroup taxa, and mitochondrial cytochrome oxidase subunit I and II (COI þ II) sequences, derived primarily from published data. Phylogenies derived from each of the two markers (28S rRNA, COI þ II) were largely (though not completely) congruent, as determined by incongruence-length difference and Kishino-Hasegawa tests. -

A Simplified Guide to DNA Evidence Introduction
A Simplified Guide To DNA Evidence Introduction The establishment of DNA analysis within the criminal justice system in the mid-1980s revolutionized the field of forensic science. With subsequent refinement of DNA analysis methods in crime laboratories, even minute amounts of blood, saliva, semen, skin cells or other biological material may be used to develop investigative leads, link a perpetrator or victim to a crime scene, or confirm or disprove an account of the crime. Because of the accuracy and reliability of forensic DNA analysis, this evidence has also become an invaluable tool for exonerating individuals who have been wrongfully convicted. The successes of DNA evidence in criminal trials has captured more than headlines, however—it has captured the public’s imagination as well. Jurors now increasingly expect DNA evidence to be presented in a wider array of cases, even when other types of evidence may be more valuable to the investigation. Principles of DNA Evidence DNA is sometimes referred to as a “genetic blueprint” because it contains the instructions that govern the development of an organism. Characteristics such as hair color, eye color, height and other physical features are all determined by genes that reside in just 2% of human DNA. This portion is called the coding region because it provides the instructions for proteins to create these features. The other 98% of human DNA is considered non- coding and the scientific community has only recently begun to identify its functions. Forensic scientists, however, use this non-coding DNA in criminal investigations. Inside this region of DNA are unique repeating patterns that can be used to differentiate one person from another. -
Solving Crimes by Using Forensic Entomology Dr
Solving Crimes by Using Forensic Entomology Dr. Deborah Waller Associate Professor of Biology Old Dominion University The Scenario The following is a hypothetical crime that was solved using insect evidence. Although fictional, this crime represents a compilation of numerous similar forensic entomology cases tried in the legal system where insects helped identify the murderer. The Crime Scene Pamela Martin, a 55 year-old woman, was found deceased in a state of advanced decomposition on March 30th. The body was discovered by her husband John on a path leading to a mountain cabin owned by the couple. The Martins had driven up to the cabin on March 1st, and John had left Pamela there alone while he completed a job in the northeastern region of the state. The Victim Pamela Martin was a former school librarian who devoted her retirement years to reading and gardening. She took medication for a heart condition and arthritis and generally led a quiet life. Pamela was married for 30 years to John Martin, a truck driver who was often gone for months at a time on his rounds. They had no children. The Cabin The cabin was isolated with closest neighbors several kilometers away. There was no internet access and cell phone service was out of range. The couple frequently drove up there to do repairs, and John often left Pamela alone while he made his rounds throughout the state. "Cabin and Woods" by DCZwick is licensed under CC BY-NC 2.0 The Police The police and coroner arrived on the scene March 30th after John called them using his Citizen Band radio when he discovered Pamela’s body. -
