Do female Eastern Bluebirds trade-off egg size with clutch size?
(East Carolina University, 2017-05-09)Egg size and clutch size are traits that show a fundamental trade-off in life history theory. Producing a larger number of offspring can come at the cost of being able to invest in those offspring. The degree of maternal ... -
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 ... -
Does history matter? : An experimental assessment of whether dragonfly colonization history affects insect biodiversity within ephemeral ponds
(East Carolina University, 2010)Current interactions among species could have an important role in controlling biodiversity. Some studies, however, have shown that the particular time a species arrives at a site during the process of community assembly ... -
DOES THE QUANTITY OF RESOURCES IN THE ENVIRONMENT ALTER THE IMPACT OF MULTIPLE PREDATORS ON THEIR PREY?
(East Carolina University, 2013)Predation is an important biological process affecting prey populations and most prey in nature are exposed to multiple predator species. Much research has revealed that the combined effect of multiple predators on their ... -
A dominant allele controls development into female mimic male and diminutive female ruffs
(2013-12)Maintaining polymorphisms for genes with effects of ecological significance may involve conflicting selection in males and females. We present data from a captive population of ruffs (Philomachus pugnax) showing that a ... -
Drosophila Ctf4 is essential for efficient DNA replication and normal cell cycle progression
(2011)Background Proper coordination of the functions at the DNA replication fork is vital to the normal functioning of a cell. Specifically the precise coordination of helicase and polymerase activity is crucial for efficient ... -
Drosophila Ctf4 is essential for genome stability and normal cell cycle progression
(East Carolina University, 2010)Proper DNA replication and well-timed cell cycle progression are vital to the normal functioning of a cell. Precise coordination between these mechanisms' constituent proteins ensures their processivity while safeguarding ... -
Drosophila Oocytes as a Model for Understanding Meiosis: An Educational Primer to Accompany “Corolla Is a Novel Protein That Contributes to the Architecture of the Synaptonemal Complex of Drosophila”
(2015-01)Achieving a thorough understanding of the events and ramifications of meiosis is a common learning objective for undergraduate introductory biology, genetics, and cell biology courses. Meiosis is also one of the most ... -
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 ... -
Drosophila Psf2 Has a Role In Chromosome Condensation
(East Carolina University, 2012)The condensation state of chromosomes is a critical parameter in multiple processes within the cell. Failures in the maintenance of appropriate condensation states may lead to genomic instability, mis-expression of genes, ... -
Duodenal carcinoma at the ligament of Treitz. A molecular and clinical perspective
(2010)Background There is very small occurrence of adenocarcinoma in the small bowel. We present a case of primary duodenal adenocarcinoma and discuss the findings of the case diagnostic modalities, current knowledge on the ...
