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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Multiple Factors Influence the Strength of Intraguild Interactions
(East Carolina University, 2011)
Species engaged in intraguild predation (IGP) not only compete for the same food resources but can also eat each other. In some cases, a predator species in a higher trophic position (i.e., a top predator) can eat a ...
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 ...
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 ...
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 ...
