Comparative Analysis of Genomic Similarity Tools in Species Identification
This study presents the development and evaluation of an automated pipeline for genome comparison, leveraging four bioinformatics tools: alignment-based methods (pyANI, Fas- tANI) and k-mer-based methods (Sourmash, BinDash 2.0). The analysis focuses on high- quality genomic datasets characterized …

Species Identification of the Stylohyoid Bone for North American Artiodactyls
Zooarchaeologists cannot identify mammal species by their stylohyoid bones. Current trends in zooarchaeological research stress the need for rigorous and accessible identification methodology. I examined the stylohyoids of 15 hooved mammals: cattle, bison, domestic sheep, bighorn sheep, Dall sheep, …

Predator species identification from saliva at kill sites with limited remains
… can provide valuable data about elusive predator species and predator-prey interactions for wildlife scientists and managers alike. However, the predator species must be definitively identified as the one responsible for the predation event. The traditional method of visually analyzing prey …

The application of a PCR based species identification method to African wildlife
Molecular based species identification is a useful tool in forensic investigations as well as routine work. The ability to cheaply and quickly determine the species of origin of a sample has become increasingly necessary as incidents of wildlife poaching, illegal meat trade and the trade of …

Functional characterization of olfactory receptors and molecular species identification of vector mosquitoes.
… dengue, malaria, yellow fever, and Zika. Not all species of mosquitoes are responsible for vectoring these pathogens however, so accurate identification and surveillance are extremely important and directly impact human health. DNA barcoding allows for a rapid, accurate, and reliable species …

Genetic and ecological investigations of European populations of the pool frog, Rana lessonae (Camerano, 1882) with allied, osteological and species identification methods
Current identification methods for distinguishing north-west European brown and water frogs are discussed and tested, to allow the presentation here, of more accurate guidance on their separation. Novel methods for the identification of species and individuals including novel, non-invasive, …

Under the trapdoor - resolving the taxonomy and phylogeography of the trapdoor spider genus Stasimopus (Mygalomorphae: Stasimopidae) of the Karoo
… This study was undertaken to understand the true species diversity and history of this genus in the Karoo region of South Africa. The Karoo is a semi-arid, unique and sensitive ecosystem which is facing pressure for development due to economic incentives. This area has long been neglected, with …

Application of a DNA Mini-Barcoding System based on the Mitochondrial Control Region for the Identification of Raw and Processed Tuna Products
<p>Accurate species identification methods are needed to combat tuna fraud, improve tuna stock regulation, and mitigate health risks associated with mislabeled tuna products. The objective of this study was to conduct a market survey of raw and processed tuna products using a DNA mini-barcoding …

Innovative molecular methods for fish species differentiation
… method for various market-relevant fish species have been developed. A DNA microarray was established using a set of 100 universal oligonucleotide probes. DNA probe signal patterns were observed to be speciesspecific, enabling species identification of unknown fish samples by comparing …

A study of the littoral marine isopod Crustacea of the Dillon Beach area
… a much more complete study of the anatomy of the species represented in the fauna than was heretofore performed. Certain anatomical structures deemed by earlier writers as specifically diagnostic are demonstrated to be unreliable and in a great many instances other structures previously neither …

DNA barcoding of forensically important flies in the Western Cape
… and developmental patterns of specific species that visit the body. As first colonisers, Calliphoridae (blow flies) are often used by forensic entomologists to determine the PMI however, developmental rates of visiting fauna differ substantially which makes correct species identification …

Determination of a robust metabolic barcoding model for chemotaxonomy in Aizoaceae species : expanding morphological and genetic understanding
… vast metabolic fingerprints of closely related species to each other, secondary metabolites tend to be unique to the samples of individual species and are identified in clustering algorithms as the variables responsible for species-specific clustering. A holistic approach to metabolic …

Pleistocene Peccaries from Guy Wilson Cave, Sullivan County, Tennessee.
… Linkage between upper dentition and species identification is suggested by comparing <em>Mylohyus fossilis</em> to <em>M. nasutus</em> from other Pleistocene-aged sites. Long-bone NISP and age profiles show a predominance of <em>Platygonus</em> adults. Tayassuidae upper canines, …

DNA+eDNA: integration of traditional and emerging tools for monitoring marine ecosystems
… thesis highlights the critical role of accurate species identification for evaluating marine biodiversity, ecological roles, and conservation needs. Traditional taxonomy often struggles with the identification of cryptic species, leading to the reliance on molecular methods such as DNA analysis. …

DNA barcoding of Jatropha curcas
… region of DNA to be used as a tool for rapid species identification. The cytochrome C oxidase gene (COXI) is widely accepted as the standard barcode for animals and currently there is no barcode for land plants. The Consortium for the Barcode of Life (CBOL) has proposed two regions of DNA to …

Measuring Trace Element Concentrations in Artiodactyl Cannonbones using Portable X-Ray Fluorescence
… to accurately identify a family, genus, or species. Traditional faunal analysis can only organize unidentifiable bone fragments into size class, and chemical methods often require the destruction of bone samples. In this thesis research, I tested a new, nondestructive faunal analysis …

Selection and Use of Aquatic Vegetation by Migratory Waterfowl in North Central Texas
… Texas. Ponds were categorized by dominant plant species into eight habitat types. Census with waterfowl species identification were performed to investigate impacts of aquatic vegetation and water depth on waterfowl. Eighteen waterfowl species were observed. Peak migration occurred in late …
