Artificial Reefs As Management Tools, Tiff Raetzel

USF Tampa Graduate Theses and Dissertations

Artificial reefs are attractive tools for fisheries management and reef conservation, as they can host large fish biomasses, including fisheries-important species, and they may supplement natural recruitment. Prior studies have established that artificial and natural reefs differ in habitat complexity and host both taxonomically and functionally distinct assemblages. These differences may impact how the reef types respond to environmental disturbance because ecosystem stability is dependent upon habitat structure, species composition, and trophic interactions. A question of management importance is whether artificial reefs host a less- or more-sensitive suite of species than natural reefs, and whether the assemblage is conducive to …

Secondary Teacher Perceptions And Practices Of Intercultural Communicative Competence Development In Online Intercultural Exchanges, Paige L. Roland
