Behavioral syndromes and their effect on dispersal in Notonecta irrorata
Kitchen, Anthony J. (East Carolina University, 2018-04-23)Dispersal is an important life-history characteristic for many organisms, including in the genus of back-swimming insect Notonecta. The propensity to disperse is a behavior that might be affected by an individual's other ... -
Does history matter? : An experimental assessment of whether dragonfly colonization history affects insect biodiversity within ephemeral ponds
Amoroso, Natalie A. (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 ... -
DOES THE QUANTITY OF RESOURCES IN THE ENVIRONMENT ALTER THE IMPACT OF MULTIPLE PREDATORS ON THEIR PREY?
Gelles, Tyler R. (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 ... -
Fear of Aquatic Predators Cause Prey to Alter Their Phenotype at Multiple Life Stages
Jones, Scott P. (East Carolina University, 2016-07-27)Many organisms can alter their behavior, life history, and morphology in response to their environment. This ability is known as phenotypic plasticity. One of the major environmental cues that triggers a phenotypic plastic ... -
How do modified nanoclays adversely affect aquatic species relative to natural nanoclay?
Tullio, Suelen C. de Morais Calado (East Carolina University, 2017-07-17)Nanoclays represent a large class of modified nanomaterials (NMs) (i.e. nanoscale particles from 1 to 100 nm) that has received great attention from the scientific and industrial communities. This material has been widely ... -
Insecticides Alter the Ability of Predator Assemblages to Suppress Prey
Sorey, Caroline C (East Carolina University, 2019-05-01)Agrochemicals are often deposited into freshwater bodies via rainfall and snowmelt events and can have consequences for populations and communities. Insecticides in aquatic systems can cause mortality, behavioral, and ... -
IS PREDATION BY TURTLES SUFFICIENTLY STRONG TO AFFECT BIODIVERSITY WITHIN FISHLESS PONDS?
Williams, Charles A. (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 ... -
Local and Regional Aspects of Habitat Quality Jointly Affect the Biodiversity of Ephemeral Ponds
Deans, Robert A. (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 ... -
Metabolic, Physiological, And Behavioral Responses Of Prey To Predation
Trone, Richard (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 ... -
Multiple Factors Influence the Strength of Intraguild Interactions
Davenport, Jon M. (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 ... -
Nonconsumptive effects in a multiple predator system reduce the foraging efficiency of a keystone predator
Davenport, Jon M.; Chalcraft, David R. (2013-09)Many studies have demonstrated that the nonconsumptive effect (NCE) of predators on prey traits can alter prey demographics in ways that are just as strong as the consumptive effect (CE) of predators. Less well studied, ... -
Predator Out of Place : The Differential Impacts of Native and Non-native Crayfish on Bufo Tadpoles
Connell, Patia M. (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)
Hernandez, Jason P. (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 ... -
SALT MARSH MOSQUITO DITCH ALTERATIONS: ECOLOGICAL IMPACTS AND PERSPECTIVES IN MANAGEMENT DECISIONS
Nolan, Casey B (East Carolina University, 2018-12-10)Salt marsh ecosystems are prized for the numerous ecological and economic services that benefit society. On the U.S. east coast, virtually all salt marsh habitat from Maine to Virginia has been hydrologically degraded by ... -
THE EFFECTS OF ZOOPLANKTON DISPERSAL ON COMMUNITY ASSEMBLY OF TEMPORARY PONDS
McCarthy, Lauren C. (East Carolina University, 2015-12-10)The dispersal of individuals among habitat patches is thought to have an important effect on ecological communities as it can influence both population dynamics and community assembly. Though much work on dispersal has ...
