Biogeographical and Genomic Analysis of Eleusine Species
(2021-12-06)
Abstract
Eleusine Gaertn. (Poaceae, subfamily Chloridoideae), is a small taxon of closely related and distinct diploids and tetraploids endemic to Africa that have been scrutinized from vegetative, floral, cytological, ...
Intraspecific variation in coral reproductive output and symbiont community structure following a thermal bleaching event
(2022-04-04)
Marine heatwaves and associated bleaching events are projected to increase in frequency and severity in the future, imperiling charismatic ecosystems such as coral reefs. Although mass bleaching events are often accompanied ...
Equity and inclusion underlie instructor assessment choices amid COVID-19 pandemic
(2022-04-21)
The coronavirus (COVID-19) outbreak mandated a rapid transition to online classes with little warning. Previous literature studying the effect of this sudden shift demonstrated enormous impacts on instructors and students. ...
Gene flow, morphology, and taxonomic revision of cave-obligate Hesperochernes pseudoscorpions
(2022-05-02)
Pseudoscorpions are small predatory arthropods that are found in surface and subterranean habitats. Subterranean habitats such as caves tend to harbor pseudoscorpion species with highly restricted gene flow and high degrees ...
The effects of fluctuating embryonic incubation temperatures and nighttime light exposure on the physiology of zebra finches (Taeniopygia guttata)
(2022-06-29)
Anthropogenic effects, such as fluctuating incubation temperatures and light pollution, can have both behavioral and physiological impacts on an organism, particularly within avian species. Specifically, when parents leave ...
Testing the Shared-Pathway Hypothesis through experimentation on the mating behavior, carotenoid biosynthesis, and mitochondrial function of Tigriopus californicus
(2022-07-13)
For decades, scientists have noted connections between individual condition and carotenoid-based coloration in terrestrial and aquatic animals. Organisms that produce more vibrant carotenoid-based coloration tend to have ...
Discovery, expression, and characterization of biosynthetic gene clusters encoding antimicrobial secondary metabolites from a soil metagenome and cultured Actinobacteria
(2022-07-19)
Dating back to the discovery of penicillin in 1928, nature and its diverse microbial life has been the most prolific source of antimicrobial compounds. These bioactive compounds are often derived from microbial secondary ...
Native Ant Biodiversity Response to A Dominant Competitor in Pine-Hardwood Forests of Alabama, USA
(2022-07-22)
This thesis explores how invasive species affect native biodiversity. Specifically, I explore how the invasive ant species, Solenopsis invicta influences the recipient native ant community in pine-hardwood forests. These ...
Descriptions and Phylogenetic Relationships of the Guiana Shield Pencil Catfishes
(2022-07-21)
The systematics of the catfish genus Trichomycterus Valenciennes 1832 are complicated and unresolved. This genus is paraphyletic, containing all members of the Trichomycterinae that cannot be adequately placed into an ...
The Involvement of Copper in Leigh Syndrome
(2022-07-29)
Leigh Syndrome is a neurodegenerative disease that presents with bilateral lesions in the brain. This condition is characterized by progressive loss of mental and movement abilities in which these symptoms start as early ...
