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 ...
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 ...
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 ...
Food and feeding habits of the spiny dogfish Squalus acanthias overwintering off the coast of North Carolina and the effects on the marine community
(East Carolina University, 2012)
Spiny dogfish (Squalus acanthias) are small, highly migratory sharks that occur in large numbers in North Carolina nearshore waters between November and March. This species has long been considered a pest by commercial ...
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 ...
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 ...
Fear of Aquatic Predators Cause Prey to Alter Their Phenotype at Multiple Life Stages
(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 ...
INVESTIGATING THE EFFECTS OF LARVAL PHENOTYPES ON TRAITS EXHIBITED AT A CRUCIAL LIFE-HISTORY SWITCH POINT
(East Carolina University, 2017-07-25)
In organisms with complex life histories, phenotypes exhibited in non-reproductive life stages are often correlated with adult performance and fitness. For example, in anurans (frogs and toads), age and size at metamorphosis ...
