Habitat Associations of Birds of North America
(2012-09-28)
I examined habitat associations of woodpeckers (Picidae) and warblers (Parulidae) on Redstone Arsenal, Madison County, Alabama. I used maps derived from satellite imagery to construct models of habitats occupied by the ...
Heat tolerance of reptile embryos in a changing world: Physiological mechanisms and ecological effects
(2020-07-09)
Aspects of global change (e.g. climate change, urbanization) create stressful thermal environments that threaten biodiversity. Oviparous, non-avian reptiles have received considerable attention because eggs are left to ...
Hemichordate phylogeny: a molecular and genomic approach
(2014-04-17)
The phylogenetic relationships within Hemichordata are significant for understanding the evolution of the deuterostomes. Hemichordates possess several important morphological structures in common with chordates, and they ...
Home Range, Activity, Movement, and Habitat Selection of the Flattened Musk Turtle (Sternotherus depressus) in the Bankhead National Forest, Alabama
(2019-07-15)
The Flattened Musk Turtle, Sternotherus depressus, is an imperiled aquatic species endemic to the Upper Black Warrior watershed in Alabama. As one of the most understudied turtles in the United States, little is known about ...
Host Specificity and Regional Endemicity in Symbiotic Dinoflagellates (Symbiodinium, Dinophyta) Associated with Sea Anemones in the Genus Aiptasia
(2009-04-13)
Recent investigations of coral reef biology have focused on the global biogeography and host specificity of Symbiodinium, a diverse group of dinoflagellates that symbiotically associate with many marine organisms, including ...
Hydrological link between the Amazon River Basin and the eastern Guiana Shield on the Neotropical ichthyofauna
(2011-11-30)
The seasonal inundation of the Rupununi savannas in south central Guyana allows for
potential faunal exchange between the Takutu and Rupununi Rivers and ultimately between the
Essequibo and Amazon Rivers. This hydrological ...
Hypoxia-induced behaviors of the ctenophore Mnemiopsis leidyi
(2016-08-05)
The hypoxia-associated behaviors of the ctenophore Mnemiopsis leidyi are not well understood, despite the ecological significant of this species and the widespread nature of hypoxic (low oxygen) events. The interface of ...
Identification and characterization of suppressors of the non-fermentable carbon source defects of coa1Δ
(2013-11-21)
The assembly of cytochrome c oxidase (COX) in yeast mitochondria is dependent on the assembly factor Coa1. ATP1 was identified as a multi-copy suppressor of the coa1∆ respiration defect. ATP1 is additive with previously ...
Identification and isolation of five developmental stages in GM-CSF-stimulated murine bone marrow culture.
(2018-04-24)
Dendritic cells (DCs) are highly potent cells that link the innate immunity with the adaptive. However, these cell types (and their precursors) are extremely rare in vivo. Considerable work has been done to map the development ...
Identification of genes involved in the production of a novel antifungal agent (7, 10, 12-trihydroxy-8(E)-octadecenoic acid) in Pseudomonas aeruginosa
(2009-08-04)
The gram-negative bacterium Pseudomonas aeruginosa catalyzes the conversion of ricinoleic acid into a novel trihydroxy fatty acid, 7, 10, 12-trihydroxy-8(E)-octadecenoic acid (TOD), that has a potent antifungal activity ...
Identification of new components involved in shoot gravitropism in Arabidopsis thaliana
(2015-07-24)
Plants can reorient their growth according to environmental cues such as light, water, nutrients, gravity etc. Shoots (hypocotyls and inflorescence stems) of the plants exhibit negative gravitropism. Germinating seeds are ...
Identification of novel biosynthetic gene clusters and bacterial taxa from a soil microbiome using metagenomic approaches
(2021-04-21)
The microbial world is home to incredible taxonomic and metabolic diversity. Microorganisms are prolific producers of secondary metabolites, which are an important source of bioactive compounds, namely antibiotics, which ...
The impact of maternal protein intake and litter size on organ and stress axis development in the house mouse (Mus musculus)
(2015-07-24)
The phenotype of an individual is determined by interactions between its genotype and its surrounding environment. Through these interactions, an individual can express a greater range of characteristics than dictated by ...
Impacts of diving tourists on coral reef community structure and herbivorous reef fish foraging behavior
(2016-07-20)
Increasing contact between humans and nature can disturb essential processes
within ecosystems. Chronic anthropogenic disturbances on coral reefs may shift benthic
community composition leading to loss of reef growth and ...
Improving the phage-displayed peptide probes for pathogen detection
(2014-12-10)
In order to minimize the danger to the public from pathogen outbreaks, it is imperative to rapidly identify the infectious agent so appropriate response can be mounted and prevent dissemination of the organism. An ideal ...
The Inflamed Gut: An Integrative Approach to Understanding the Impact of Inflammation on Bacteriophage-Host Dynamics.
(2020-05-15)
The intestinal microbiome is a diverse and dynamic microbial ecosystem residing within the gastrointestinal tract. The mammalian intestine is home to both commensal and opportunistic pathogenic microorganisms. The immune ...
Influence of Bait on Assessment of Biodiversity of Small Mammals
(2007-05-15)
Two experiments were designed to test effectiveness of bait packs containing peanut butter and rolled oats (peanut butter bait packs) compared to empty bait packs in traps used to capture small mammals. In experiment A, ...
The Influence of Coarse Woody Debris, Disturbance, and Restoration on Biological Communities in Sandy Coastal Plain Streams
(2009-12-18)
The influence of instream habitat on benthic macroinvertebrates was assessed
from multiple descriptive and experimental studies within the Fort Benning Military
Installation (FBMI), Georgia and the Tuskegee National ...
The influence of environmental variation on the microbiome during early-life stages in reptiles
(2023-07-24)
My dissertation research seeks to understand how environmental variation, including maternal effects, might influence the microbiome of reptiles and how those differences translate to phenotypic variation. My research ...
Interaction between SQSTM1/p62 and HDAC6: Impacts on the Aggresome-autophagy pathway and Microtubule Dynamics
