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 ...
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 ...
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 ...
River Herring Nursery Habitat in Albemarle Sound, North Carolina, Inferred from Otolith Microchemistry
(East Carolina University, 2012)
River herring is a collective term used to describe two similar alosine species: alewife Alosa pseudoharengus and blueback herring A. aestivalis. Both of these anadromous species are native to the Atlantic coast of North ...
RESPONSE OF A SPARTINA PATENS-DOMINATED OLIGOHALINE MARSH TO NITROGEN ENRICHMENT IN COASTAL NORTH CAROLINA, USA.
(East Carolina University, 2013)
Coastal marshes are highly productive ecosystems that play a significant role in the global carbon budget. Anthropogenic alterations to coastal landscapes can significantly impact these marsh ecosystems, though the actual ...
