A Seascape Approach To Predicting Reef Fish Distribution, Brian K. Walker

Oceanography Faculty Theses and Dissertations

Linking small-scale measurements of species distributions to broad-scale seascapes is necessary to understanding and predicting organismal distributions and their dynamics. This applies to reef fish populations as well. Reef fish studies are often limited to small spatial scales because of logistical and economic constraints; however, viewing the data at larger spatial scales might elucidate unforeseen relationships and patterns and facilitate regional management and conservation efforts. To address this growing need, an empirical model was created to predict reef fish abundance and species richness for the entire seascape using the relationship between the fish, benthic habitats, and GIS-derived topographic complexity metrics …
