Behavioral Ecology Of Territorial Aggression In Uca Pugilator And Uca Pugnax, Abbey N. Thomas
Honors Theses
The nature of animal aggression has long been a research interest in many different scientific fields. Resources, including food, shelter, and mates are all common assets for which animals compete. Two species of fiddler crabs, the Atlantic Sand Fiddler Crab (Uca pugilator) and the Atlantic Marsh Fiddler Crab (U. pugnax) were studied in regards to their aggression shown when competing for shelter. One crab was placed in a contained shelter for two days, and then a second of the same species was introduced. Aggressive interactions were scored and compared with claw and carapace size to ascertain …

Microplastics In Fiddler Crabs (Genus Uca), Gabrielle Forbes, Eric Rosch
Honors Theses
Microplastics, as defined by NOAA, are small plastic pieces less than five millimeters long, which cannot be seen with the naked eye. The production of plastic products and plastic use has exponentially increased since the start of plastic usage. Consequently, the amount of plastic waste has also increased greatly. Plastic waste that has been thrown out by humans into the environment breaks down into microscopic pieces, causing harm to organisms that live there. The purpose of this study was to see if there were microplastics passing through fiddler crabs (genus Uca), collected from the marsh at Waties Island, SC. Fecal …
