Effects Of Osteopontin Single Nucleotide Polymorphisms On Bull Semen Quality, Chance L. Williams
Graduate Theses and Dissertations
Two groups of bulls were utilized to evaluate if single nucleotide polymorphisms (SNP) in the Bos taurus OPN gene (GenBank accession # AY878328.1) promoter region were related to bull semen quality variables as evaluated by computer assisted semen analysis (CASA). Group 1 consisted of 19 Angus and Balancer bulls, ranging in age from 5 to 8 years, which were collected weekly during a 2-month period (July 15, 2010 through September 19, 2010). Group 2 consisted of 16 Brahman influenced (1/8 to 3/16 Brahman) bulls, mean age = 1.1 ± 0.1 year, that were collected monthly for a 7 month period …
Ozark Highland Cunaxidae (Acari: Prostigmata): Descriptions And Keys To Genera Found To Occur In The Region And A New Phylogenetic Hypothesis For The Family, Michael Joseph Skvarla
Ozark Highland Cunaxidae (Acari: Prostigmata): Descriptions And Keys To Genera Found To Occur In The Region And A New Phylogenetic Hypothesis For The Family, Michael Joseph Skvarla
Graduate Theses and Dissertations
Fourteen genera of Cunaxidae (Acari: Prostigmata) are reported from the Ozark Highlands for the first time. Descriptions, diagnoses, and illustrated keys to genera and world species are given. Five new species are described and illustrated and an additional 6 known species are recorded from the region. The first rigorous phylogenetic hypothesis for Cunaxidae is presented. Based on morphology, it suggests the current subfamilial classification scheme does not reflect the evolutionary history of the family. Unfortunately, bootstrap values and resolution are low, suggesting the need for further indepth molecular analyses.
