Are Marine Migrations of Striped Bass Genetically Pre-determined? : An investigation of Albemarle Sound-Roanoke River Striped Bass Migratory Patterns
(East Carolina University, 2010)Striped bass, Morone saxatilis, is one of the most thoroughly studied anadromous fish species in the United States, with records governing the management of the species dating back to the late 1600s. However, management ... -
Bioenergetics and Trophic Impacts of Invasive Indo-Pacific Lionfish
(East Carolina University, 2010)Indo-Pacific lionfish, Pterois volitans and Pterois miles, are non-native marine fish with established populations in the western North Atlantic Ocean and Caribbean Sea. Rapid population growth threatens native fish ... -
Biogeographic Characterization of Fishes from Intertidal Sandflats in Pamlico River, North Carolina
(East Carolina University, 2012)The spatial and temporal changes in fish community structure in Pamlico River, North Carolina were analyzed. Salinity and temperature are important water quality parameters influencing fish community structure in estuaries. ... -
CAN NUTRIENT ADDITIONS MEDIATE GAPE LIMITED PREDATION IN LARVAL RANA SPHENOCEPHALA?
(East Carolina University, 2013)Some predators are limited in the size prey item that they can catch and consume, and this is referred to as "gape limited". Prey found with these predators may have the ability to respond by growing rapidly to reach a ... -
Cryptic Seed Heteromorphism in Packera tomentosa (Asteraceae) : Differences in Seed Mass Characteristics and Germination
(East Carolina University, 2012)Germination requirements of seeds can dictate when and where plant offspring establish. Microsites available for germination vary spatially and temporally in factors such as temperature and moisture; thus, the production ... -
DETECTION AND DISTRIBUTION OF THE AMPHIBIAN FUNGAL DISEASE CHYTRIDIOMYCOSIS IN PERUVIAN AMPHIBIANS
(East Carolina University, 2012)Chytridiomycosis is an amphibian disease caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd;Longcore et al. 1999). This disease has been identified by the Amphibian Conservation Action Plan as one of the main ... -
Developing a Panel of Microsatellite Markers for Common Moorhen (Gallinula chloropus) as a Research Tool for Population Studies
(East Carolina University, 2013)The common moorhen (Gallinula chloropus) sometimes exhibits brood parasitism - a parent manipulating a conspecific host to raise its offspring, relieving the parent of the encumbrance of parental investment. It has been ... -
Does history matter? : An experimental assessment of whether dragonfly colonization history affects insect biodiversity within ephemeral ponds
(East Carolina University, 2010)Current interactions among species could have an important role in controlling biodiversity. Some studies, however, have shown that the particular time a species arrives at a site during the process of community assembly ... -
DOES THE QUANTITY OF RESOURCES IN THE ENVIRONMENT ALTER THE IMPACT OF MULTIPLE PREDATORS ON THEIR PREY?
(East Carolina University, 2013)Predation is an important biological process affecting prey populations and most prey in nature are exposed to multiple predator species. Much research has revealed that the combined effect of multiple predators on their ... -
Ecological effects of rising sea level on shorezone
(East Carolina University, 2009)This study examines the ecological effects of sea-level rise on shorezone in the Neuse River estuary and western Pamlico Sound, NC. Shorezone is defined here in an ecohydrological context as the area of wetland that extends ... -
Effects Of Nutrient Availability And Disturbance On The Composition And Diversity Of Soil Microorganisms
(East Carolina University, 2015)Determining how factors such as disturbance and nutrient availability affect species diversity in a community has been a major goal of community ecology. The purpose of this study was to look at how species diversity and ... -
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. ... -
Historical Ecology of Striped Bass Stocking in the Southeastern United States
(East Carolina University, 2012)Striped bass (Morone saxatilis) is the most recreationally and commercially important non-salmonid fish species in the continental United States. As such, it has been exploited to the point of collapse at various points ... -
IDENTIFICATION OF GEOCHEMICAL TRACERS WITHIN BIOMINERALS OF JUVENILE AND LARVAL MERCENARIA MERCENARIA : IMPLICATIONS FOR MODELING LARVAL DISPERSAL
(East Carolina University, 2013)This study was designed to investigate the application of geochemical signals within biominerals to identify site fidelity and natal origin of the commercially valuable bivalve Mercenaria mercenaria. My first study ... -
IS PREDATION BY TURTLES SUFFICIENTLY STRONG TO AFFECT BIODIVERSITY WITHIN FISHLESS PONDS?
(East Carolina University, 2011)Ecologists have long known that predation can have a strong effect on the diversity and abundance of prey in ecological communities. Much evidence on the importance of predation in aquatic systems has stemmed from studies ... -
Local and Regional Aspects of Habitat Quality Jointly Affect the Biodiversity of Ephemeral Ponds
(East Carolina University, 2012)The biodiversity of local communities is likely affected by both local habitat quality and by the quality of the landscape surrounding the locality. In pond environments, habitat quality may be affected by the kind of leaf ... -
Maternal input of Striped Bass (Morone saxatilis) : Determining a mother's life history from its progeny in coastal North Carolina
(East Carolina University, 2014)Otolith studies have become more prevalent in recent years as use has expanded from ageing to examination of migration patterns and fidelity to natal habitats, and more recently examining otoliths for possible maternal ... -
Metabolic, Physiological, And Behavioral Responses Of Prey To Predation
(East Carolina University, 2015)Predators are known to cause prey to alter their morphology, life history or behavior in ways that reduce the likelihood of the prey being consumed by the predator. Seldom considered, however, are the consequences of ... -
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 ... -
Movements of North Carolina Striped Bass, Morone saxatilis, Inferred through Otolith Microchemistry
(East Carolina University, 2014)Striped Bass, Morone saxatilis, is an anadromous, recreationally and commercially important fish species found throughout the U.S. Atlantic east coast, whose migrations have been intensely studied. A review of the relevant ...
