Pupil and teacher perceptions of the taxonomic classification of Senior Certificate Mathematics Higher Grade examination questions
This dissertation seeks to apply a taxonomic classification to Senior Certificate Mathematics examination questions. Candidates who wrote a typical question paper as well as the teachers who taught them were asked to give their taxonomic perceptions of each question. The taxonomic classifications …

Classification of Carpiodes Using Fourier Descriptors: A Content Based Image Retrieval Approach
<p>Taxonomic classification has always been important to the study of any biological system. Many biological species will go unclassified and become lost forever at the current rate of classification. The current state of computer technology makes image storage and retrieval possible on a global …

Deep learning approach to metagenomic binning
… into a low-dimensional vector space based on taxonomic classification. We show that our method can get the speed and sensitivity necessary taxonomic classification. Our method was able to achieve 13% accuracy on identifying novel genus of bacteria as compared to 7% accuracy of k-mer embedding. …

An evaluation of free amino acids as chemotaxonomic markers in Protea L. species
… the past. It was hoped to contribute towards the classification of plants by applying chemotaxonomy or chemosystematics, whereby chemical evidence is incorporated with morphological and other information. The genus Protea L. was an obvious choice for the initial material of such research as it is …

THE BROWN BEAR GUT MICROBIOME: A NOVEL TOOL FOR CONSERVATION & MANAGEMENT
… for 16S rRNA amplicon sequencing and microbial taxonomic classification. My results indicate that location and diet drive GMB variation and GMB composition reflects diverse foraging strategies while allowing brown bears to achieve similar body condition outcomes. Monitoring brown bear GMBs could …

Molecular Detection of Tick-Borne Pathogens Associated With Ixodid Tick Species Infesting Migratory Songbirds and Ruminants
… respectively by using 454-based pyrosequencing. Taxonomic classification of ticks from ruminants reveals that the most predominant phylum was proteobacter in both Hyalomma spp. and firmicutes in Rhipicephalus microplus. The overall microbial diversity found highest in Rhipicephalus microplus …

Characterization, classification, and productivity studies of typic hapludult mapping units in the southern Piedmont of Virginia
… southern Piedmont to assess characterization, classification, and productivity of soils mapped as Cecil-Pacolet (clayey, kaolinitic, thermic Typic Hapludults). Effects of erosion on Ap and Bt soil properties and soybean grain yields were studied in Pittsylvania and Lunenburg counties. …

Untangling Genomes from Metagenomes
… Puget Sound during autumn and spring. Community taxonomic classification and quantification revealed a diverse and changing assemblage of Bacteria and Archaea, including enigmatic members of the uncultured marine Euryarchaeota. Targeted metagenomic assembly produced the first genome representing …

Comparative Systematics of Subterranean Amphipod Crustaceans in the Families Crangonyctidae and Bogidiellidae
… deals with the systematics of two different taxonomic groups of subterranean amphipods (Crustacea). Therefore, rather than being a single project, this study is divided into several sub-projects. Altogether, the chapters for the sub-projects are composed of five publications. An introductory …

Systematic relationships in southern African Francolins as determined from mitochondrial DNA
… There is little accord concerning the taxonomic classification of its members. In the past, information on this group has been provided by morphological and palaeontological evidence. An investigation into the molecular history of this group is presented, using mitochondrial DNA (mtDNA) …
