Possible Effects Of Climate Change On Induced Defenses In Tadpoles
(East Carolina University, 2015)Global climates are changing and the rate of change is expected to increase in the next century. Researchers predict that temporary ponds will be affected, resulting in shorter average hydroperiods (the amount of time a ... -
Posttranslational modifications in the CP43 subunit of photosystem II
(East Carolina University, 2002-11-12)Photosystem II (PSII) catalyzes the light-driven oxidation of water and the reduction of plastoquinone; the oxidation of water occurs at a cluster of four manganese. The PSII CP43 subunit functions in light ... -
Potassium deficiency had a significant effect on the growth, development and microRNA-mediated mechanism in wheat (Triticum aestivum L.)
(East Carolina University, 2020-11-19)Potassium is a crucial nutrient in the growth and development of plants and lack of available potassium was found to have significant affects in altering the morphology and gene expression of wheat. Wheat plants were grown ... -
A practical guide and power analysis for GLMMs: detecting among treatment variation in random effects
(2015-09)In ecology and evolution generalized linear mixed models (GLMMs) are becoming increasingly used to test for differences in variation by treatment at multiple hierarchical levels. Yet, the specific sampling schemes that ... -
Predator Out of Place : The Differential Impacts of Native and Non-native Crayfish on Bufo Tadpoles
(East Carolina University, 2010)Predators have been shown to alter important fitness components (larval period, mass at metamorphosis, and overall survivorship) of larval anurans. Uncommonly studied predators of tadpoles include crayfish. Both native and ... -
Predicting non-target impacts from a biocontrol weevil on a federally threatened thistle of the upper Great Lakes
(East Carolina University, 2017-04-28)Better understanding of the ecological and evolutionary consequences of plant-insect interactions has important applications in ecology, agriculture, and pest management. Larinus planus Fabricius (Coleoptera: Curculionidae), ... -
Prevention of synaptic loss in cortico-hippocampal culture by silencing Kremen1 with siRNA
(East Carolina University, 2017-05-19)Research has shown that Alzheimer’s disease could be a result of an accumulation of amyloid β (Aβ) plaques and tau protein. The accumulation of Aβ activates p53, which leads to an increase of Dickkopf-1 (Dkk1). When Dkk1 ... -
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, ...
