Characterizing the role of the Early Gene at 23 (E23) in Drosophila Melanogaster Oogenesis
(East Carolina University, 2016-04-29)
Drosophila melanogaster (fruit fly) females undergo oogenesis to create oocytes from undifferentiated stem cells in the ovary. Similar to estrogen in humans, the steroid hormone ecdysone in fruit flies has a known role in ...
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 ...
Genetic mapping of the female mimic morph locus in the ruff
(2013)
Background
Ruffs (Aves: Philomachus pugnax) possess a genetic polymorphism for male mating behaviour resulting in three permanent alternative male reproductive morphs: (i) territorial ‘Independents’, (ii) non-territorial ...
Mismatched anti-predator behavioral responses in predator-naïve larval anurans
(2015-12-07)
Organisms are adept at altering behaviors to balance the tradeoff between foraging and predation risk in spatially and temporally shifting predator environments. In order to optimize this tradeoff, prey need to be able to ...
Redefining the Postcolonial Identity Through the Deconstruction of Chimamanda Ngozi Adichie's Novels
(East Carolina University, 2015-12-10)
In her 2009 TED Talk, “The Danger of a Single Story,” Chimamanda Ngozi Adichie explains that when one group is defined by one story, they are reduced to one-dimensional caricatures; they are objectified. The danger in a ...
The EBM-DPSER Conceptual Model: Integrating Ecosystem Services into the DPSIR Framework
(2013)
There is a pressing need to integrate biophysical and human dimensions science to better inform holistic ecosystem management supporting the transition from single species or single-sector management to multi-sector ...
High major histocompatibility complex class I polymorphism despite bottlenecks in wild and domesticated populations of the zebra finch (Taeniopygia guttata)
(2015-12-01)
Background
Two subspecies of zebra finch, Taeniopygia guttata castanotis and T. g. guttata are native to Australia and the Lesser Sunda Islands, respectively. The Australian subspecies has been domesticated and is now an ...
Observations on spiny dogfish () captured in late spring in a North Carolina estuary
(2014-10)
Five spiny dogfish were captured in early-mid May during gillnet and longline sampling targeting juvenile coastal sharks in inshore North Carolina waters. Dogfish captures were made within Back Sound and Core Sound, North ...
Decisions Under Duress: Influences on Official Decision Making During Superstorm Sandy
(East Carolina University, 2015-12-08)
During impending storms, emergency managers and politicians are tasked with the difficult decision of whether or not to issue evacuation orders for their area. This study uses Superstorm Sandy as a case study and investigates ...
THE EFFECTS OF ZOOPLANKTON DISPERSAL ON COMMUNITY ASSEMBLY OF TEMPORARY PONDS
(East Carolina University, 2015-12-10)
The dispersal of individuals among habitat patches is thought to have an important effect on ecological communities as it can influence both population dynamics and community assembly. Though much work on dispersal has ...
