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 ...
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 ...
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 ...
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 ...
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 ...
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. ...
Population Structure Of River Herring In Albemarle Sound, North Carolina, Inferred From Geometric Morphometrics And Otolith Shape Analysis
(East Carolina University, 2015)
Alewife Alosa pseudoharengus and Blueback Herring Alosa aestivalis, collectively known as River herring, use tributaries of the Albemarle Sound, North Carolina as spawning and nursery habitats. Stocks of these anadromous ...
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 ...
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 ...
