Advances In The Systematics And Evolutionary Understanding Of Fireflies (Coleoptera: Lampyridae), Gavin Jon Martin
Advances In The Systematics And Evolutionary Understanding Of Fireflies (Coleoptera: Lampyridae), Gavin Jon Martin
Theses and Dissertations
Fireflies are a cosmopolitan group of bioluminescent beetles classified in the family Lampyridae. The first catalogue of Lampyridae was published in 1907 and since that time, the classification and systematics of fireflies have been in flux. Several more recent catalogues and classification schemes have been published, but rarely have they taken phylogenetic history into account. Here I infer the first large scale anchored hybrid enrichment phylogeny for the fireflies and use this phylogeny as a backbone to inform classification. Several classification changes are made throughout the group with emphasis on morphological traits that support the AHE hypothesis. Building off of …

Unsupervised Biomedical Named Entity Recognition, Omid Ghiasvand
Theses and Dissertations
Named entity recognition (NER) from text is an important task for several applications, including in the biomedical domain. Supervised machine learning based systems have been the most successful on NER task, however, they require correct annotations in large quantities for training. Annotating text manually is very labor intensive and also needs domain expertise. The purpose of this research is to reduce human annotation effort and to decrease cost of annotation for building NER systems in the biomedical domain. The method developed in this work is based on leveraging the availability of resources like UMLS (Unified Medical Language System), that contain …
Taxonomic Studies Of Trombiculid Mites, Jack T. Reed
Taxonomic Studies Of Trombiculid Mites, Jack T. Reed
Theses and Dissertations
Five publications and one manuscript concerning the taxonomic studies of trombiculid mites are submitted. Publications include a revision of the North American genus Comatacarus Ewing, the erection of the following genera by Brennan and Reed: Loomisia, Atelepalme, Phalcophila, and Nycterinastes. Discussions of the genera Aitkenius Brennan and Polylopadium Brennan and Jones are also included. The subfamily Leeuwenhoekinae is reviewed on the basis of neo-tropical representatives (unpublished manuscript). The genus Odontacarus comprises 66% of the chiggers examined, and 82% of these were identified as O. tubercularis (Brennan). Odontacarus fieldi Brennan and Jones and O. cayolargoensis Brennan are synonomized under O. tubercularis …
A Revision Of The Hedysarum Boreale Complex, Terry Edwin Northstrom
A Revision Of The Hedysarum Boreale Complex, Terry Edwin Northstrom
Theses and Dissertations
The Hedysarum boreale complex consists of all North American Members of the genus Hedysarum which possess free wing auricles, sub-equal calyx teeth, hidden leaflet veins, and wingless loment articles. One species, two subspecies, and three varieties are recognized. The traditional methods of comparative morphology are employed in delimiting species in the herbarium, but pertinent data from field work are also included. The somatic chromosome number was determined for all taxa, and was found in all cases to be 16. Distribution maps, illustrations, and graphical comparisons of taxa are included.
