Describing Nitrogen Dynamics in Eastern North Carolina Waterfowl Impoundments by Combining Field-Scale and Laboratory-Scale Based Approaches
(East Carolina University, 2018-08-01)
Waterfowl impoundments are wetlands that are hydrologically managed to provide food and habitat for migratory bird populations. Certain impoundment types have recently been found to export nitrogen (N) loads during seasonally ...
Effects of Zinc Oxide Nanoparticles on the Pharyngeal Pumping and Neurological Behavior of C. elegans
(East Carolina University, 2018-08-02)
Cogent data regarding the effects of manufactured zinc oxide nanoparticles (ZnO-NPs) on human health and other organisms is limited. With the prominence of manufactured ZnO - NPs increasing rapidly in recent years, the ...
Effects of nutrient addition on plant community composition: a functional trait analysis in a long-term experiment
(East Carolina University, 2018-07-19)
The effects of nutrient availability on plant community composition and diversity have been well-documented, but the mechanisms behind the community response remain unclear. Plant species interact with variation in the ...
SOCIAL REGULATION OF THE ENDOCANNABINOID SYSTEM IN ZEBRAFISH MOTOR CIRCUITS
(East Carolina University, 2018-07-20)
Social status-dependent modulation of neural circuits has been investigated extensively in vertebrate and invertebrate systems. However, the effect of social status on shifting the balance in activation between competing ...
Mechanisms of germ cell development in Drosophila oogenesis.
(East Carolina University, 2018-07-17)
Germ cell development requires interplay between factors that control cell fate and division. Early in their development, germ cells are an interconnected group of mitotically dividing cells. Key regulatory events then ...
STICKLEBACK COLOR FLUCTUATION OVER THE BREEDING SEASON: AN IN DEPTH FIELD STUDY
(East Carolina University, 2018-07-17)
The coloration of the threespine stickleback (Gasterosteus aculeatus) is well studied in the field of evolution, mainly with regard to the role of sexual selection (Ostlund-Nilsson et al., 2006; Foster et al., 2008; Hendry ...
ENDOCRINE DISRUPTING CHEMICALS ALTER STEROID TRANSPORT PROTEINS AND STEROID FREE AND BOUND FRACTIONS
(East Carolina University, 2018-05-03)
The effects of endocrine disrupting chemicals (EDCs) on the development of sexually dimorphic characteristics in vertebrates have been studied extensively for over sixty years. Throughout this time, studies have focused ...
Folic acid elicits diverse effects over all major life stages and body systems
(East Carolina University, 2018-04-25)
Over several decades, the vitamin supplement folic acid has been praised for its ability to reduce neural tube defects in the developing embryo. Many studies show that folic acid plays a vital role in the reduction of ...
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 ...
