Measuring the Ecosystem Impacts of Commercial Shrimp Trawling and Other Fishing Gear in Core Sound, North Carolina Using Ecological Network Analysis
(East Carolina University, 2012)The impacts of commercial trawling are well documented, especially alteration of benthic environments, removal of targeted and by-catch species, and alteration of food webs. I investigated and modeled the impacts of shrimp ... -
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 ... -
Multifunctional experimental assessment in a newly established Mediterranean restored marsh : marsh elevation, carbon accumulation and pollutant concentration reduction
(East Carolina University, 2014)The Delta of the Ebro River (Catalonia, Spain) is among the most important marsh areas in the Western Mediterranean Sea, highly valuable both economically and ecologically. Fluvial sediment reduction by dams in a relative ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Response of Baldcypress (Taxodium distichum) at Different Life Stages to Flooding and Salinity
(East Carolina University, 2014)Baldcypress are dominant trees in forested coastal wetlands. As sea levels rise, it is important to increase our understanding of how increased salinity and flooding will affect forested coastal wetlands. This study combined ... -
Responses of dominant marsh macrophytes to inundation and disturbance and assessing marsh ecosystem services
(East Carolina University, 2009)Within two hydrodynamically different inundation regimes in North Carolina, the growth response and interactions of two dominant marsh macrophytes were evaluated over a range of inundation periods to understand better how ... -
Responses of Leaf Litter Breakdown Rates and Microbial Enzyme Activity to Salinity in North Carolina Wetlands
(East Carolina University, 2014)Sea-level rise and human activities are causing the increase of salinity in coastal freshwater wetlands. Increased salinity in some wetlands has been found to accelerate leaf litter decomposition, an important driver of ... -
Risk Assessment and Behavioral Choices of Larval Anurans (Lithobates Sphenocephalus)
(2011-04)Larval anurans assess risk and make behavioral choices to avoid predation. Since antipredator behaviors may reduce foraging opportunities, prey behavioral decisions can be constrained by a tradeoff between survival and ... -
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 ... -
Stable Carbon and Nitrogen Isotope Analysis of Captive Northern Galagos (Otolemur garnettii) Fed Experimental “Frugivorous” and “Invertebrate” Diets
(East Carolina University, 2023-07-21)Otolemur garnettii are small (~ 770g), semi-solitary, omnivorous primates and although there have been studies examining the behavioral ecology of the species very little is known about its diet. This is due in part to the ... -
Storm surge and ponding explain mangrove dieback in southwest Florida following Hurricane Irma
(Springer Nature, 2021-06-28)Mangroves buffer inland ecosystems from hurricane winds and storm surge. However, their ability to withstand harsh cyclone conditions depends on plant resilience traits and geomorphology. Using airborne lidar and satellite ... -
A study of composition, abundance, and fatty acid profiles of zooplankton in Albemarle Sound and Chowan River, North Carolina during spring and early summer
(East Carolina University, 2014)In the Albemarle Sound and Chowan River, North Carolina, river herring (alewife and blueback herring) once comprised a commercially important fishery; however, this fishery has since collapsed and a moratorium on river ... -
A Study of the Abundance, Distribution, and Grazing Effects of Zooplankton in the Chlorophyll Maximum (CMAX) of the Neuse River Estuary, North Carolina
(East Carolina University, 2012)Phytoplankton tend to accumulate in distinct zones referred to as chlorophyll maxima, or CMAX. A pronounced CMAX occurs in the Neuse River Estuary (NRE), North Carolina, where as much as over 60% of the estuary's phytoplankton ...
