Food and Feeding of Young Striped Bass in the Lower Roanoke River and Western Albemarle Sound, North Carolina, 1990-1991
(East Carolina University, 1992-07)
This study was conducted during the springs of 1990 and 1991 to provide information on possible causes of the decline in the Roanoke/Albemarle striped bass stock. Striped bass in this system migrate approximately 130 miles ...
An assessment of the polytypic status of the Namib darkling beetles Onymacris unguicularis and Onymacris rugatipennis
(2014-12-10)
The southern African beetle genus Onymacris (family Tenebrionidae) comprises 14 species, six of which are polytypic. Despite longstanding research on the physiological and behavioral adaptations of these desert beetles, ...
THE EFFECTS OF PRENATAL LEAD EXPOSURE ON THE DEVELOPMENT OF BIOMARKERS OF ALZHEIMER’S DISEASE
(2015-04)
While often well known for its adverse effects on memory, Alzheimer’s disease (AD) is also noteworthy for being the sixth leading cause of death in the United States. An estimated 5.2 million Americans had the disease as ...
A Biopsychosocial Examination of Transcatheter Aortic Valve Replacement Health Outcomes
(East Carolina University, 2015)
Cardiovascular disease (CVD) is the leading cause of death in the world accounting for 17.3 million deaths annually. Transcatheter aortic valve replacement (TAVR) was developed 13 years ago to treat people suffering from ...
Experimental evidence for predator learning and Müllerian mimicry in Peruvian poison frogs (Ranitomeya, Dendrobatidae)
(East Carolina University, 2013)
Poison frogs are characterized by bright coloration, striking patterns, and toxicity; they have thus become a classic example of aposematism. Ranitomeya imitator mimics three congeneric model species (R. fantastica, R. ...
Conspicuous Female Ornamentation and Tests of Male Mate Preference in Threespine Sticklebacks (Gasterosteus aculeatus)
(2015-03-25)
Sexual selection drives the evolution of exaggerated male ornaments in many animal species. Female ornamentation is now acknowledged also to be common but is generally less well understood. One example is the recently ...
The largest subunit of RNA polymerase II from the Glaucocystophyta: functional constraint and short-branch exclusion in deep eukaryotic phylogeny
(East Carolina University, 2005-12)
Background: Evolutionary analyses of the largest subunit of RNA polymerase II (RPB1) have yielded important and at times provocative results. One particularly troublesome outcome is the consistent inference of independent ...
Microarray and pathway analysis reveals decreased CDC25A and increased CDC42 associated with slow growth of BCL2 overexpressing immortalized breast cell line
(East Carolina University, 2008-10)
Bcl-2 is an anti-apoptotic protein that is frequently overex-pressed in cancer cells but its role in
carcinogenesis is not clear. We are interested in how Bcl-2 expression affects non-cancerous breast
cells and its role ...
The Manganese Transporter MntH Is a Critical Virulence Determinant for Brucella abortus 2308 in Experimentally Infected Mice
(East Carolina University, 2009-08)
The gene designated BAB1_1460 in the Brucella abortus 2308 genome sequence is predicted to encode the manganese transporter MntH. Phenotypic analysis of an isogenic mntH mutant indicates that MntH is the sole high-affinity ...
A Müllerian mimicry ring in Appalachian millipedes
(East Carolina University, 2009-06-16)
Few biological phenomena provide such an elegant and straightforward
example of evolution by natural selection as color mimicry among unrelated organisms. By mimicking the appearance of a heavily defended aposematic ...
