Dodge, Duck, Dip, Dive & Dependence: Using Dodgeball to Explore Frequency Dependent Selection
(2016-09)
The term frequency dependence describes scenarios in which the likelihood
of an event occurring is strongly tied to how common a particular trait is.
Understanding frequency dependence is key to understanding ...
Toxic Effects of Chlorpyrifos Exposure on Development of Caenorhabditits Elegans
(East Carolina University, 2016-12-15)
Chlorpyrifos is a commonly utilized organophosphate pesticide, and as recently as 2007, was the most commonly used insecticide within the United States. Its ubiquity is concerning given its potential to cause developmental ...
The mismatch between current statistical practice and doctoral training in ecology
(2016-08-17)
Ecologists are studying increasingly complex and important issues such as climate change and ecosystem services. These topics often involve large data sets and the application of complicated quantitative models. We evaluated ...
Delination of Coastal Shark Habitat within North Carolina Waters Using Acoustic Telemetry, Fisher-Independent Surveys, and Local Ecological Knowledge
(East Carolina University, 2016-07-20)
Knowledge of shark habitat preferences and use patterns is important to effectively manage shark fisheries and account for interactions between sharks and species targeted by other fishery management or conservation efforts. ...
Fear of Aquatic Predators Cause Prey to Alter Their Phenotype at Multiple Life Stages
(East Carolina University, 2016-07-27)
Many organisms can alter their behavior, life history, and morphology in response to their environment. This ability is known as phenotypic plasticity. One of the major environmental cues that triggers a phenotypic plastic ...
Investigating the role of CRL5, an ubiquitin ligase, in ovarian follicle development.
(East Carolina University, 2016-07-20)
During oogenesis, follicle cells surround maturing oocytes, which produce factors necessary for proper oocyte growth and development. Correct encapsulation of the oocyte by follicle cells is therefore essential for ...
A Genetic Mosaic Screen Reveals Ecdysone-Responsive Genes Regulating Drosophila Oogenesis
(2016-08)
Multiple aspects of Drosophila oogenesis, including germline stem cell activity, germ cell differentiation, and follicle survival, are regulated by the steroid hormone ecdysone. While the transcriptional targets of ecdysone ...
Vectors of transmission: An early nicotine puff triggers a long-lasting microRNA molecular “memory” in C. elegans.
(East Carolina University, 2016-06-16)
The prevalence of passive and active nicotine exposure among neonates, children and adolescents remains relatively high and varies among cultures and countries. Currently, there is ample evidence that a safe nicotine dose ...
Exploring the roles of horizotnal gene transfer in metazoans
(East Carolina University, 2016-07-20)
Horizontal gene transfer (HGT; also known as lateral gene transfer, LGT) refers to the movement of genetic information between distinct species by overcoming normal mating barriers. Historically HGT is only considered to ...
Seasonal home range dynamics and sex differences in habitat use in a threatened, coastal marsh bird
(2016-12-22)
A comprehensive understanding of spatiotemporal ecology is needed to develop conservation strategies for declining species. The king rail (Rallus elegans) is a secretive marsh bird whose range historically extended across ...
