This document provides a list of publications by Danielle Bethea, including peer-reviewed journal articles, technical reports, and presentations. The publications cover topics such as population structure and gene flow of small coastal sharks, analysis of movement patterns of juvenile sawfish, reassessment of trophic levels of sharks, distribution and community structure of coastal sharks in the Gulf of Mexico, essential fish habitat of juvenile coastal sharks, and selectivity of gillnets for juvenile sharks. Many of the publications use data from tagging studies of small coastal and hammerhead sharks conducted in the Gulf of Mexico and southeastern United States.
