Intraspecific signaling functions of juvenal plumage
(2009-04-22)
The function and evolution of avian plumage coloration has been the subject of many studies over the past decade, but virtually all of this research has focused on the plumages of sexually mature individuals. The color ...
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 ...
Invasive Characteristics of Chinese Privet (Ligustrum sinense Lour.) in a Bay Swamp in the Fall Line Hills of East-Central Alabama
(2008-08-15)
Exotic species often become invasive because of an ability to occur in many habitat types with a variety of environmental variables. One species of plant that is particularly invasive throughout the southeastern United ...
Investigating mitochondria-induced premature aging due to reproduction and environment in semi-natural enclosed wild-derived house mice
(2023-05-02)
Reproduction is a highly energetic process requiring both prenatal and postnatal investment for female mammals. Under the disposable soma theory (DST), prenatal investment includes reallocation of resources used to maintain ...
Investigating the therapeutic potential of REV-ERB⍺ activation in chronic inflammatory diseases
(2024-05-01)
Metabolic-associated steatohepatitis (MASH) is a metabolic disease of the liver, that manifests itself as steatohepatitis, inflammation, and fibrosis. It has the potential to progress to cirrhosis and hepatocellular carcinoma ...
Investigation of elemental defense and trophic transfer of metals using beet armyworm, Spodoptera exigua, Hübner
(2012-08-06)
Elemental defense is a phenomenon in which high concentrations of a metal in plant tissues can defend a plant from herbivores. Elemental defense is one of the hypotheses proposed to explain the evolution of metal ...
An Investigation of Species Relationships within Marshallia Schreb. [Asteraceae] and Mitochondrial Genomes within Poaceae
(2018-04-24)
Genomic sequencing has become ubiquitous within the discipline of Biology. Here I use
two case studies in which whole genomic DNA facilitates answers to foundational biological
questions for organisms that do not have ...
Investigation of the Impact of Copper Homeostasis on Cellular Physiology
(2024-05-01)
The copper pool within the mitochondrial matrix is required for assembly and activity of cytochrome c oxidase and a portion of copper/zinc superoxide dismutase. The mitochondrial copper exists bound to an anionic, fluorescent ...
Investigations of cellular dynamics during bleaching in the symbiotic anemone, Aiptasia pallida
(2013-07-19)
The global decline of coral reefs continues at an increasing rate despite efforts to identify key cellular interactions responsible for the breakdown of these essential ecosystems. Coral bleaching involves the loss of ...
Investigations of Neural Ontogeny in the Larval Oyster Crassostrea virginica and the nudibranch Berghia verrucicornis: A Histological and Immunohistochemical Approach
(2010-06-07)
Bivalves are a diverse group of molluscs that inhabit both marine and freshwater habitats. These animals play a vital role in the success of entire aquatic ecosystems by filtering the water and providing structural complexity ...
Investment in Carnivory in Drosera capillaris: Effects of Varying Light Levels on Trichome Density
(2011-08-01)
In this study I examined Drosera capillaris, which is a plant common in the southeastern Gulf Coastal Plain’s pitcher plant bogs. Investment in carnivory has been examined in other groups of carnivorous plants but very ...
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 ...
