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. ...
The Relations Among Executive Dysfunction, Delay Aversion and Phonemic Awareness in Proschoolers
(East Carolina University, 2013)
The Dual Pathways theory of AD/HD explains that there may be two independent neurologically based pathways in which AD/HD may develop: executive dysfunction (EDF) and delay aversion (DAv). A separate line of research has ...
The Rhetorical Challenge of Whiteness within Blackboard for African American Bidialectal Students at Elizabeth City State University
(East Carolina University, 2013)
This research will attempt to discover if there is a rhetorical challenge due to whiteness within Elizabeth City State University's (ECSU) Blackboard (Bb) online education system when it is utilized by African American ...
Theoretical aspects and modelling of cellular decision making, cell killing and information-processing in photodynamic therapy of cancer
(2013)
BACKGROUND:
The aim of this report is to provide a mathematical model of the mechanism for making binary fate decisions about cell death or survival, during and after Photodynamic Therapy (PDT) treatment, and to supply ...
Boron Stress Responsive MicroRNAs and Their Targets in Barley
(2013)
Boron stress is an environmental factor affecting plant development and production. Recently, microRNAs (miRNAs) have been found to be involved in several plant processes such as growth regulation and stress responses. In ...
The scale and evolutionary significance of horizontal gene transfer in the choanoflagellate
(2013-10)
Background
It is generally agreed that horizontal gene transfer (HGT) is common in phagotrophic protists. However, the overall scale of HGT and the cumulative impact of acquired genes on the evolution of these organisms ...
Phenotypic and Genetic Divergence among Poison Frog Populations in a Mimetic Radiation
(2013)
The evolution of Müllerian mimicry is, paradoxically, associated with high levels of diversity in color and pattern. In a mimetic radiation, different populations of a species evolve to resemble different models, which can ...
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 ...
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 ...
