Are All Parasitic Infections Created Equal? An Examination of Differential Infection Effects and Responses in Native and Non-Native Hosts
(East Carolina University, 2018-12-10)
Interactions between native and introduced species are complex, multifaceted, and can have cascading effects throughout an ecosystem. While scientists have taken great strides to understand how these dynamics change with ...
ADAMTS9 IS NECESSARY FOR THE SEXUAL DEVELOPMENT OF FEMALE ZEBRAFISH
(East Carolina University, 2018-12-10)
The ovary is a unique organ as it must cyclically alter its structure to accommodate the growth, development, and release of oocytes. The processes of oogenesis and ovulation requires structural modifications made to the ...
Adaptation in a Changing World: Evolutionary mechanisms of salt tolerance in a coastal amphibian
(East Carolina University, 2018-07-20)
In order to predict evolutionary outcomes of environmental change on populations in nature, we need an improved understanding of the biological mechanisms that affect whether organisms will adapt to a changed environment. ...
Integrative multi-omic analyses identify novel biomarkers for recurrent stroke in participants from the Vitamin Intervention for Stroke Prevention (VISP) clinical trial
(East Carolina University, 2019-05-01)
Background: Recurrent strokes are deadlier and more disabling than primary strokes and over 185,000 individuals in the US suffer a recurrent event each year. Current diagnostic and at-risk identification tools are inadequate ...
Nutrient contributions from septic systems in nutrient-sensitive watersheds: Quantifying nutrient inputs, reduction methods, and economic feasibility
(East Carolina University, 2019-04-30)
Eutrophication of surface waters is a global issue threatening aquatic ecosystems and recreational opportunities. Nutrient management strategies exist to reduce nutrient inputs from various sources; however, septic systems ...
The effects of climate variability on the timing of ichthyoplankton ingress through Beaufort Inlet, NC, USA
(East Carolina University, 2019-04-30)
Climate change has shifted the timing of seasons in many ecosystems worldwide. Species are responding to these shifting seasons with shifts of their own, both in space via migrations and in time via phenology. However, ...
ARE ALL FISH NURSERIES EQUAL? DETERMINING HOW FOOD WEB DYNAMICS AFFECT FISH NURSERY HABITAT
(East Carolina University, 2018-07-23)
The fish nursery habitat concept has been used to define important habitat for larval and juvenile fish throughout coastal and estuarine areas. Nursery habitat has been defined as an area that produces more fish biomass, ...
Environmental Development of the External Genitalia
(East Carolina University, 2018-07-24)
Hypospadias is one of the most common birth defects in the world. The incidence of hypospadias has nearly doubled over the past 50 years and now occurs on average in 1 in 125 male newborns each year. Hypospadias is a ...
A Candidate Gene Study: Finding Associations between Recurrent Stroke and Genetic Variants of Five Folate-Mediated One Carbon Metabolism Pathway Genes
(East Carolina University, 2019-04-25)
Stroke is the second leading cause of death in the world and fifth in the United States. Both in the United States and worldwide, stroke is the leading cause of disability. Stroke is a cerebrovascular event which results ...
TEMPERATURE, RESOURCE INPUT, AND STANDING GENETIC VARIATION AFFECT PREDATOR RESPONSES OF PHYSA ACUTA
(East Carolina University, 2019-04-26)
In urban areas, features such as high percentages of impervious ground cover, patchiness, and storm water runoff can lead to increases in temperature and external nutrient input into aquatic systems. Such factors can lead ...
