MicroRNA Expression Analysis in the Cellulosic Biofuel Crop Switchgrass () under Abiotic Stress
(2012)Switchgrass has increasingly been recognized as a dedicated biofuel crop for its broad adaptation to marginal lands and high biomass. However, little is known about the basic biology and the regulatory mechanisms of gene ... -
Microsatellite analysis of brook trout, Salvelinus fontinalis, in western Pennsylvania
(East Carolina University, 2017-05-05)In western Pennsylvania, the brook trout, Salvelinus fontinalis, has dramatically declined in population due to the environmental stressors of mining, logging, water withdrawal, and acid deposition. Brook trout are game ... -
Millipede Taxonomy after 250 Years: Classification and Taxonomic Practices in a Mega-Diverse yet Understudied Arthropod Group
(2012)Background The arthropod class Diplopoda is a mega-diverse group comprising >12,000 described millipede species. The history of taxonomic research within the group is tumultuous and, consequently, has yielded a questionable ... -
The mismatch between current statistical practice and doctoral training in ecology
(2016-08-17)Ecologists are studying increasingly complex and important issues such as climate change and ecosystem services. These topics often involve large data sets and the application of complicated quantitative models. We evaluated ... -
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 ... -
MITOCHONDRIAL DNA VARIATION IN THE PITCHER PLANT FLY SARCOPHAGA SARRACENIAE: EXPLORING POSSIBLE INFLUENCES OF HOST SPECIFICITY AND GEOGRAPHIC STRUCTURING
(East Carolina University, 2019-05-03)North American pitcher plants (Sarracenia) are a recently evolved (~3 my) assemblage of 11 carnivorous species. Sarracenia pitchers also provide resources (food, shelter) for certain arthropods, including two genera of ... -
Molecular and Cellular Biology Animations: Development and Impact on Student Learning
(East Carolina University, 2005)Educators often struggle when teaching cellular and molecular processes because typically they have only two-dimensional tools to teach something that plays out in four dimensions. Learning research has demonstrated that ... -
Molecular chaperone Tetratricopeptide repeat protein 2 (Tpr2) is essential for germline stem cell self-renewal and timely cyst divisions in Drosophila melanogaster oogenesis
(East Carolina University, 2019-05-02)Steroid hormones influence cell proliferation and cell fate in developing and injured tissues. Although steroid hormone signaling has been well-studied, the precise mechanisms by which cells specifically receive steroid ... -
Molecular Epidemiology of MRSA Among Patients and Employees in a Surgical Intensive Care Unit
(East Carolina University, 2011)Methicillin-resistant Staphylococcus aureus (MRSA) is a pervasive drug resistant human pathogen and has become widespread in hospitals around the world. MRSA infections cause approximately 19,000 deaths among hospitalized ... -
Molecular evolution of venom proteins in Ctenidae (Order: Araneae) spiders
(East Carolina University, 2021-01-20)Spiders comprise the largest group of venomous animals and are a pivotal component of the global ecosystem with approximately 50,000 species spread across nearly every habitat on Earth. The family Ctenidae Keyserling, 1877 ...
