Summary
Forensic Entomology Name: May 2012 Forensic Entomology. Introduction Forensic entomology can be defined as “the branch of forensic science in which information about insects is used to draw conclusions when investigating legal cases relating to both humans and wildlife, although on occasion the term may be expanded to include other arthropods” (Gennard, 2007, p…

Throughout the twentieth century scientific methods of analysis have improved greatly, with the result that at the present time forensic entomology is a well-established discipline within forensic science, complete with rigorous protocols and extensive underpinning research which help to ensure that it provides relevant, accurate and reliable evidence for crime investigation and prosecution purposes. Forensic entomology is therefore a dual discipline combining elements of natural science in the methods of collection and analysis of samples, and elements of criminology, in the interpretation and application of results, and in the preservation of evidence which is reliable enough to stand up to scrutiny in the criminal justice system. Although these two areas have a different focus, they are closely aligned in crime investigation procedures, requiring collaboration across disciplines according to clear scientific principles. This paper explores the contribution that forensic entomology makes to crime investigation and prosecution by examining three of its major areas of application: 1. Determining the post mortem interval (PMI); 2. Providing human DNA linkages and 3. Providing toxicology information. A number of limitations as well as legal and procedural issues are covered also in section 4. 1.Determining the Post Mortem Interval (PMI) through forensic entomology. 1.1 Species involved. Corpses provide a very specialized ephemeral environment which is colonized by particular communities of arthropods in a predictable manner, with one species following on after another in a process known as “succession” (Horswell, 2004, p. 347). The main species The first species to arrive, often within minutes of death, are blowflies. Blowflies from the Calliphoridae family are generally the first stage invaders, and then after these others follow Sarcophagids which constitute a second stage, often overlapping with the first stage somewhat. After this follow the third stage Muscids and Piophilids (Horswell, 2004, p. 348). 1.2 Types of information obtainable. Scientists are able to obtain good information from a corpse soon after death, by taking photographs, measuring temperature, observing rigor mortis and any wounds, and conducting various other tests on the tissue. With increasing passage of time, however, the tissue degenerates, and it is more difficult to obtain reliable data. Because the life cycle of insects is known, and the effects of temperature and weather can be factored in to the equation, careful collection of insects at the scene can provide useful estimate of the PMI. Empirical work in the laboratory has established standard growth times for many of the most common carrion feeding species, and this means that the determination of PMI has become the most used application of forensic entomology in modern crime scenes (Nabity et al. 2006, p. 1276). Another useful piece of information that can be obtained from examination of species present in a corpse is the whether or not the body has been moved. ...Download file to see next pagesRead More

Elements of human conquest including deforestation, urban crawl, and the consumption of disproportionate resources have led to the early extinction of a great number of species. According to Miller (2009), “The balance between the formation of new species and extinction of existing species determines the earth’s biodiversity” (p. 185). Therefore, it must be understood that extinction is part of the natural process of the development of life. Human activity... Head:...

...mating habits, uses a similar costume design style, but also added in some interesting color and light effects to focus the viewer's attention on the narrator's voice instead of the actual speaker. This video features a model of a praying mantis built of paper or cardboard that resembles an origami sculpture. The general feel of this video is one of simplicity, rather than the previous documentary's cheap feel, though the cheesy effect remains to a certain extent. The video is extremely short and fast, probably to imitate the mating habits of the subject species in question. It exemplifies the life span of the male praying mantis, that he exists only to copulate with the female and to feed her so she will bear his young....

...?Altruism in Society In the concept of natural selection, certain species carry a reproductive or trait advantage over other species. In this case, they are more fit for the environment, so they survive and reproduce. As the social conditions of the species become more complex, such necessitates more complex social structures. In the case of the animal kingdom, highly complex social structure systems develop in which there are actions that are dictated and certain tasks, which are divided among those in the community. The same is true in insects. Insects, such as bees and ants, have a highly organized and efficient structure of social organization. It is because of this collective effort that they are able to organize and build... in Society...

Small pox was one of the most deadly diseases to have ever inflicted human race, causing very high mortality rates across the world. According to Maxcy (1998), small pox in the military caused more deaths that the gun, cannon and the sword combined and it was one of the earliest forms of bioterrorism in the world. Edward Jenner’s small pox vaccine that was developed from the cowpox provided the much-needed remedy for the dreaded disease and currently, the world is free of small pox...

Similarly, threats, vulnerabilities and risks associated with these factors are also in parallel. As threats make their way from vulnerabilities, a mechanism is vital to monitor, eliminate and report these issues. Incident response plan (IRP) illustrates a security incident along with the related incident response phases. Likewise, the plan consists of documentation related to information channels. For instance, in what way the information has been passed to the applicable person, incident assessment, eliminating...

Entomology. insect. Sexual Selection

...Sexual Selection al Affiliation: Sexual selection Sexual selection occurs in two major ways; intersexual selection whereby males fight among themselves in order to be attractive to the females and the intra-sexual selection whereby members of the limited sex fight with each other to gain access to the limiting sex. In the process of sexual selection due to the competition, organisms tend to develop various adaptations. Sexual selection explains why the females and males of similar species usually vary in shape and size. This for instance it explains why the stag beetle has fearsomely oversized mandibles that cannot be used for eating as it is with other insects. The two point mandibles found in the male beetle are because... Selection al...

...that it can be used to provide evidence. Encryption was used in the past to prevent people from viewing incriminating files (Taylor, Haggerty, Gresty, & Hegarty, 2010). A message is encoded using a particular key, hence making it impossible for anybody to decrypt it. Lastly, media database systems can be unified into one. Encryption and stenography can be used legitimately by forensic examiners to ensure that there is minimal tampering with the collected evidence. Stenography was used in the past to ensure confidential communication. Secondly, it can be used to protect data since it is embedded. References Bennett, S., Maton, K., & Kervin, L. (2008). The “digital...

...Forensic Document Examination Questioned documents are a common case in many legal proceedings. Forensic analysts are thus faced with a task of analysis the contents of the documents, nature of the materials used and the source. One of the primary tasks of forensic experts is to examine the individual characteristics of a document and match them with characteristics of a printer or photocopier. The printers and copiers always transfer their characteristics to the documents. The paper discusses the various characteristics of printers and copiers that make them readily identifiable. Such characteristics include; toner elements, grabber marks, graphic marks from specific...
