The evolution of complex calls In meadow Katydids
(University of Missouri--Columbia, 2018)
Meadow Katydids (genera Orchelimum and Conocephalus) are a specious group often are found in habitats with several species within the group living in sympatry. They produce complex calls with two distinct phrases, "buzzing" ...
Conservation genetics of conflict in the Asian elephant, Elephas maximus
(University of Missouri--Columbia, 2021)
The Asian elephant (Elephas maximus) is an endangered species whose distribution spans 13 countries in south, southeast, and insular Asia. The primary threats to the survival of this species include direct conflict, primarily ...
Impact of selective motor neuron death on hypoglossal motor neuron survival and tongue morphology in a novel model of dysphagia
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Amyotrophic lateral sclerosis (ALS) is a devastating disease characterized by the progressive loss of motor neurons and paralysis of the muscles they ...
Characterization of the relationship between radiographic grading and biomarkers in patients with knee osteoarthritis
(University of Missouri--Columbia, 2020)
"Osteoarthritis (OA) is a whole-joint degenerative disease, affecting more than 25% of the adult population. Currently, OA is most commonly diagnosed based on radiographic documentation. However, radiographic grading is ...
Genome-wide exploration of direct GBX2 target genes and their contributions to mouse development
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The cells that comprise the vertebrate nervous system require molecular cues to determine their cellular position, identity and their ability to make ...
Regulation of ceramide synthase 1 in cellular stress response
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Ceramides are intimately involved in a wide range of cellular processes. In mammals, de novo ceramide synthesis is catalyzed by the 6 ceramide synthase ...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
The vital rates (e.g., survival, growth, and reproduction) of distinct life stages within a species are known to influence the growth and persistence of populations. As such, studies describing stage-specific vital rates, ...
Ecological genomics of divergence, admixture, and fitness in the smallmouth bass (Micropterus dolomieu)
(University of Missouri--Columbia, 2021)
their extensive native distribution. Much less is known about levels and distribution of diversity within the species. In 1940, Carl Hubbs and Reeve Bailey published descriptions of two distinct subspecies: the Northern Smallmouth Bass (M. d. dolomieu), inhabiting...
Amphibian metamorphosis and juvenile terrestrial performance following chronic cadmium exposure in the aquatic environment
(University of Missouri--Columbia, 2005)
[mu]g Cd/L. The experimental endpoints were survival, mass and age at metamorphosis, and whole body Cd content. Both species had a decrease in survival and increase in larval period and Cd content with increasing aqueous Cd concentration. However...
Elucidation of the genetic control of carbohydrate partitioning in Zea mays
(University of Missouri--Columbia, 2019)
Carbohydrate partitioning, the process of transporting carbohydrates from sites of synthesis in hotosynthetic tissue to developing sink tissues, is crucial for the growth, development, and yield in plants and crops. ...
