Tadpole Begging Behavior And Parent-Offspring Interactions In The Mimic Poison Frog
(East Carolina University, 2015)
Studies on offspring begging behavior have focused on whether the behavior communicates offspring need and guides parental food provisioning in the context of honest signaling theory. However, despite the plethora of ...
Neurological Effects Of A Single Low Level Blast Overpressure Exposure : Behavior And Micro RNA Mechanisms Of Mild Traumatic Brain Injury In A Rodent Model
(East Carolina University, 2015)
The increased use of explosive devices within warfare and acts of terrorism has allowed blast overpressure exposure (BOE) to become a significant concern. The most common wound sustained by BOE is blast-induced mild traumatic ...
An investigation of alkaloid sequestration by the poison frog Dendrobates auratus when fed the fire ant Solenopsis invicta
(East Carolina University, 1/13/16)
Poison frogs are known for their bright coloration, parental care, and defensive toxins. Over 850 different alkaloids have been discovered in the skin of poison frogs. The alkaloid defenses are acquired from a specialized ...
Characterization Of 'Fuzzy Tassel' Male Sterility Defects Implicates Novel MiRNA-Regulated Pathways In Maize Stamen Development
(East Carolina University, 2015)
The maize 'fuzzy tassel' ('fzt') mutant is caused by a mutation in 'dicer-like1' and has broad developmental defects. 'dicer-like1' encodes a key enzyme for microRNA (miRNA) biogenesis and many miRNAs are reduced in 'fzt' ...
The Effects of Social Status on Dopaminergic Regulation of Neural Circuit Activation and Behavior
(East Carolina University, 2017-07-19)
Social hierarchies can be observed within communities across many species and allow for proper allocation of resources. When forming social hierarchies, animals that display the most aggressive behaviors generally emerge ...
Characterization of Social Status-Dependent Neuromodulation in Zebrafish (Danio rerio)
(East Carolina University, 2017-06-28)
In zebrafish (Danio rerio), social interactions between adult males consist of a series of aggressive encounters that ultimately lead to the formation of stable hierarchies of either socially dominant or subordinate animals. ...
Reproductive Toxicity of Diazinon on Caenorhabditis elegans
(East Carolina University, 2017-07-17)
Worldwide, pesticide usage is on the rise. From 2006-2007, the global market saw a 1% increase in overall pesticide usage (Environmental Protection Agency 2012), a small percentage until you consider that one percent ...
Drosophila Ovarian Stem Cell Establishment is Regulated by Nuclear Hormone Receptor ftz-f1
(East Carolina University, 2017-06-28)
Stem cells are a fundamental underpinning of tissue biology. Loss of the self-renewing function of stem cells leads to conditions such as infertility and tissue wasting. Stem cells integrate a variety of signals to maintain ...
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 ...
A high-efficiency CRISPR/Cas9 system for targeted mutagenesis in Cotton (Gossypium hirsutum L.)
(2017-03-03)
The complex allotetraploid genome is one of major challenges in cotton for repressing gene expression.
Developing site-specific DNA mutation is the long-term dream for cotton breeding scientists. The
clustered regularly ...
