Mammalian Trait Evolution: Macroevolutionary And Comparative Genomic Analyses Of Diet And Ursid-Specific Adaptations, Matthew David Pollard

Electronic Theses and Dissertations Archive

Complex traits such as diet have shaped the evolutionary success of species, driving the diversity of form and function that we observe across the tree of life. My research investigates the genomic and macroevolutionary forces behind diet and other complex traits, revealing how they mediate evolutionary change across Mammalia. I utilized two complementary approaches for understanding the evolution of diet in mammals. First, I created two continuous dietary variables—degree of carnivory and degree of dietary specialization—to quantify the impact of diet on mammalian speciation. I found that degree of carnivory, rather than dietary specialization, significantly influenced speciation, but did not …

The Activity And Origin Of The Chitinases In The Gut Of The Mediterranean House Gecko, Alec John

Masters Theses (Archived)

Chitin is a major component of the exoskeleton of arthropods as well as the cell wall of fungi. This amino polysaccharide polymer provides structure and protection to these organisms and represents a significant barrier to digestion of arthropod prey and fighting fungal infections. Chitinases are enzymes that break down chitin. Smaller insectivores, based upon the higher surface-to-volume ratio of their even smaller prey, ingest a large amount of chitin per unit prey item. Therefore, they represent high-likelihood opportunities to bio prospect for novel chitinases that may be effective against pathogenic fungi. Fungal infections are notoriously difficult to treat, and they …

Pmp2+ Scs Maintain The Survival And Functioning Of Large-Caliber Motor Axons, Mikolaj Kozlowski

Arts & Sciences Graduate Student Theses and Dissertations

Neurodegenerative diseases are characterized by selective neuronal vulnerability, a phenomenon in which a specific pathology induces the death of a particular subpopulation of neurons. For example, selective neuronal vulnerability in the peripheral nervous system results in sensory, motor, or mixed peripheral neuropathies. While the intrinsic differences between neuronal subtypes cannot fully explain the basis of selective neuronal vulnerability, it is plausible that it partially stems from neuron extrinsic mechanisms such as the malfunction of distinct Schwann cell (SC) subtypes. Recently, we identified an exciting subpopulation of myelinating SCs characterized by the expression of Adamtsl1, Cldn14, and Pmp2 (hereafter referred to …
