Ecological and Life History Factors Influence Habitat and Tool Use in Wild Bottlenose Dolphins (Tursiops sp.)
(Georgetown University, 2012)
While it has long been known that individual animals behave quite distinctively from other conspecifics, only recently has this intraspecific behavioral variation itself been the subject of investigation rather than a ...
Male Contest Competition and Mating Success in the Parasitoid Wasp Nasonia vitripennis (Pteromalidae)
(Georgetown University, 2014)
Contest competition is the direct, often aggressive struggle for mates, resources, or both. Contest winners exclude others from access to key, monopolizable resources, and are therefore expected to have the highest mating ...
Exploring Variation in Learning Ability in Pieris rapae, the Cabbage White Butterfly
(Georgetown University, 2013)
Learning abilities allow animals to modify their behaviors based on experience; such plasticity provides an adaptive mechanism for responding to environmental unpredictability. As with any heritable trait subject to natural ...
Social Networks and Fitness Consequences of Early Sociality in Wild Bottlenose Dolphins (Tursiops sp.)
(Georgetown University, 2011)
Despite recent investigations into the relationship between adult social bonds and fitness in socially complex species, remarkably little attention has focused on the consequences of early sociality. For this dissertation ...
No Longer Forgotten: Pupation as a Critical Link in the Lepidopteran Life Cycle
(Georgetown University, 2021)
Holometabolous insects, those that undergo complete metamorphosis, owe their tremendous evolutionary success in large part to an efficient division of labor between a larval phase that focuses on feeding, and an adult phase ...
