Characterization of MiR319-Regulated TCPs in Maize Development
(East Carolina University, 1/13/16)Maize produces two inflorescences, the tassel and the ear, that are essential for reproduction. Both inflorescences arise from similar inflorescence primordia and are patterned largely by the same developmental regulators. ... -
An investigation of alkaloid sequestration by the poison frog Dendrobates auratus when fed the fire ant Solenopsis invicta
(East Carolina University, 1/13/16)Poison frogs are known for their bright coloration, parental care, and defensive toxins. Over 850 different alkaloids have been discovered in the skin of poison frogs. The alkaloid defenses are acquired from a specialized ... -
Comparison of a Traditional Teaching Model to the SCALE-UP Teaching Model in Undergraduate Biology: A Mixed Method Study
(East Carolina University, 1/13/16)This project compared a SCALE-UP teaching model to a traditional teaching model. Traditional teaching is now considered a poor motivator for student performance and interests, and the SCALE-UP model was proposed to combat ... -
A QUALITATIVE STUDY OF MICROBES IN SERPENTINITE-HOSTED SUBSURFACE ENVIRONMENTS
(East Carolina University, 1/13/16)Over the last two decades, serpentinizing environments have been studied with regards to the biogeochemistry of these habitats, but significantly less is known about the microbiology within these environments. Serpentinization ... -
Determining the Chemical Structure of Brucebactin: The Sole Complex Siderophore Utilized by the Pathogenic Bacterium Brucella Abortus
(East Carolina University, 1/13/16)Brucellosis is a zoonotic bacterial disease that affects many around the world. There are over half a million new cases each year and prevalence rates in some areas of the world exceed 10 new cases per 100,000 in the ... -
Maturation and fecundity of the Neuse and Tar-Pamlico Rivers striped bass (morone saxatilis) stocks in coastal North Carolina
(East Carolina University, 1/13/16)The Albemarle/Roanoke stock makes up the largest contingent of Striped Bass (Morone saxatilis) in the state; however, other economically important populations exist elsewhere. The Central Southern Management Area (CSMA) ... -
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 ... -
Phage-associated lysozyme of Staphylococcus Aureus :its characterization and use in genetic transformation
(East Carolina University, 1974) -
Alteration of In Vivo Cellulose Ribbon Assembly by Carboxymethylcellulose and Other Polysaccharides
(East Carolina University, 1982)In vivo cellulose ribbon assembly by the Gram-negative bacterium Acetobacter xylinum can be altered by incubation in carboxymethylcellulose (CMC), a negatively charged water-soluble cellulose derivative, and also by ... -
Effects of ovarian denervation on compensatory ovarian hypertrophy in hypophysectomized rats
(East Carolina University, 1982) -
Development of Fed and Starved Striped Bass (Morone saxatilis) Larvae from the Roanoke River, North Carolina
(East Carolina University, 1986-07)Fed and unfed striped bass larvae were reared in a laboratory using ambient Roanoke River water to determine differences in growth and development. These differences were used to histologically determine the nutritional ... -
Abundance and Viability of Striped Bass Eggs Spawned in Roanoke River, North Carolina, in 1988
(East Carolina University, 1989-10)Sampling to estimate production and viability of striped bass eggs was conducted at Pollock’s Ferry on the Roanoke River, North Carolina, from 10 April to 7 June 1988. Samples were taken by towing paired nets at the surface ... -
Abundance and Viability of Striped Bass Eggs Spawned in the Roanoke River, North Carolina, in 1988

Patterns of Succession in Man-Made and Natural Wetlands
(East Carolina University, 1990-03)The response of estuarine benthos to disturbance was investigated to test the hypotheses that season, sediment, composition, and location significantly affect patterns of recolonization. The study was conducted in two ... -
Roanoke River Water Flow Committee Report for 1988 and 1989
(East Carolina University, 1990-04)A committee of 20 representatives of State and Federal agencies and university scientists was formed in 1988 to gather information on all resources of the lower Roanoke River watershed in North Carolina and to recommend ... -
Benthic Invertebrate Utilization of Man-Made and Natural Wetlands
(East Carolina University, 1990-04)The benthic invertebrate communities of man-made and natural oligohaline wetlands were studied over time with the objectives of: (1) comparing faunal utilization of man-made and natural systems; (2) determining the rate ... -
Growth and Survival of Leiostomus Xanthurus (Spot) in Man-Made and Natural Wetlands
(East Carolina University, 1990-04)Growth and survival of the benthic feeding fish Leiosrotnus xanrhurus (‘spot”) was compared in man-made (Project Area 2) and natural oligohaline subtributaries of the Pamlico River Estuary. Experiments during 1984 defined ... -
Abundance and Viability of Striped Bass Eggs Spawned in Roanoke River, North Carolina, in 1989
(East Carolina University, 1990-11)Sampling to estimate production and viability of striped bass eggs was conducted at Barnhill’s Landing on the Roanoke River, North Carolina, from 15 April to 15 June 1989. Samples were taken by trailing paired nets at the ... -
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 ... -
