Prey Responses to Predator Chemical Cues: Disentangling the Importance of the Number and Biomass of Prey Consumed
(2012)To effectively balance investment in predator defenses versus other traits, organisms must accurately assess predation risk. Chemical cues caused by predation events are indicators of risk for prey in a wide variety of ... -
Priority effects of overwintered Rana tadpoles on larval Southern toad (Bufo terrestris Bonnaterre)
(East Carolina University, 2010)In natural ecosystems, the order of species arrival can impact the development of the community. In the Atlantic Coastal Plain of the Carolinas, wetland ponds exhibit a wide range of hydroperiods, ranging from ponds that ... -
Processing of bistranded abasic DNA clusters in γ-irradiated human hematopoietic cells
(East Carolina University, 2004)Clustered DNA damages—two or more lesions on opposing strands and within one or two helical turns—are formed in cells by ionizing radiation or radiomimetic antitumordrugs. They are hypothesized to be difficult to repair, ... -
PROLACTIN FUNCTION IN ZEBRAFISH DEVELOPMENT
(East Carolina University, 2010)Extensive studies have implicated a myriad of functional roles for prolactin (PRL) and prolactin receptor (PRLR) across a variety of adult vertebrate species. However, much less is known about the physiological role(s) of ... -
Proserpinaca: Photoperiodic and Chemical Differentiation of Leaf Development and Flowering
(East Carolina University, 1967-05)Proserpiniaca palustris L. produced juvenile leaves on 8-hour photoperiods, adult leaves on 12-hour photoperiods, and adult leaves and flowers on 14-hotur photoperiods. Treatment of pliants growing on 8- and 14-houir ... -
Proteome quantification of cotton xylem sap suggests the mechanisms of potassium-deficiency-induced changes in plant resistance to environmental stresses
(2016-02)Proteomics was employed to investigate the molecular mechanisms of apoplastic response to potassium(K)-deficiency in cotton. Low K (LK) treatment significantly decreased the K and protein contents of xylem sap. Totally, ... -
Psf2, a member of the heterotetrameric GINS Complex, plays a role in cell cycle progression and maintenance of genomic integrity
(East Carolina University, 2010)Multiple proteins are involved in the complete and accurate replication of the genome during S phase of the cell cycle. At the G1/S phase transition, the heterotetrameric GINS complex is recruited to the origin, and ... -
Purifying Scorpion Antarease from E. coli
(East Carolina University, 2018-05-03)Vesicular trafficking is a system of intracellular transport that allows for the distribution and secretion of molecules. In the pancreas, normal secretory processes have been found to be interrupted by Antarease, a ...
