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 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 ... -
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 ... -
A Synthesis of Red Drum Feeding Ecology and Diets from North Carolina and South Carolina
(East Carolina University, 2014)The trophic interactions of the red drum Sciaenops ocellatus have been previously researched. However diet data on the largest adults (>750mm TL) are very limited. As fisheries management moves towards a goal of multi-species ... -
TEMPORAL AND SPATIAL GRADIENTS IN PHYTOPLANKTON PIGMENTS IN THE TAR-PAMLICO RIVER ESTUARY
(East Carolina University, 2016-04-28)Phytoplankton form the base of most aquatic food webs, and their biomass and the composition of their communities directly impact upper trophic levels. Phytoplankton chlorophyll a concentrations in aquatic environments ... -
The Effects Of Environmental Variation On Individual Variation
(East Carolina University, 2015)Despite general consensus among ecologists that variation is ubiquitous and important in nature, ecological experiments have historically focused on changes in mean response assuming a constant environment and interchangeable ... -
ZOMBIE HIDE & SEEK: INVASIVE PARASITE’S INFLUENCE ON HOST PREDATORY HIDING BEHAVIOR IN MUD CRABS
(East Carolina University, 2018-05-03)Parasites are known to affect behavior and physiology of hosts, influencing how hosts interact with biotic and abiotic factors of the community. An invasive castrating parasitic barnacle, Loxothylacus panopaei (L. panopaei), ...
