Rattus Norvegicus As A Biological Detector Of Clandestine Remains And The Use Of Ultrasonic Vocalizations As A Locating Mechanism, Gabrielle M. Johnston
Rattus Norvegicus As A Biological Detector Of Clandestine Remains And The Use Of Ultrasonic Vocalizations As A Locating Mechanism, Gabrielle M. Johnston
Master's Theses
In investigations, locating missing persons and clandestine remains are imperative. One way that first responder and police agencies can search for the remains is by using cadaver dogs as biological detectors. Cadaver dogs are typically used due to their olfactory sensitivity and ability to detect low concentrations of volatile organic compounds produced by biological remains. Cadaver dogs are typically chosen for their stamina, agility, and olfactory sensitivity. However, what is not taken into account often is the size of the animal and the expense of maintaining and training the animal. Cadaver dogs are typically large breeds that cannot fit in …
Trace Dna Detection Using Diamond Dye: A Recovery Technique To Yield More Dna, Leah Davis
Trace Dna Detection Using Diamond Dye: A Recovery Technique To Yield More Dna, Leah Davis
Master's Theses
This study aspires to find a new screening approach to trace DNA recovery techniques to yield a higher quantity of trace DNA from larger items of evidence. It takes the path of visualizing trace DNA on items of evidence with potential DNA so analysts can swab a more localized area rather than attempting to recover trace DNA through the general swabbing technique currently used for trace DNA recovery. The first and second parts consisted of observing trace DNA interaction with Diamond Dye on porous and non-porous surfaces.
The third part involved applying the Diamond Dye solution by spraying it onto …
Nekton Usage Of High Marsh Habitats In Connecticut Salt Marshes, With Emphasis On The Genus Fundulus, Amanda L. Tucker
Nekton Usage Of High Marsh Habitats In Connecticut Salt Marshes, With Emphasis On The Genus Fundulus, Amanda L. Tucker
Master's Theses
Large scale habitat use patterns of salt marsh nekton are fairly well understood, but small-scale patterns within marsh habitats are not as well known, including the genus Fundulus, an important salt marsh species. This is an area of study that needs more research, particularly in light of increases in salt marshes loss within the last several decades. Salt marshes are a primary habitat for Fundulus species. Sea level rise and urbanization have been major contributors to salt marsh loss and alteration.
Salt marshes are highly variable habitats both spatially and temporally due to tidal cycles, high and low marsh areas …
