![]() We evaluated which factors influenced the likelihood of detection of individuals, analyzed patterns of movement and occurrence, and identified variability in habitat selection among species and regions, using a dataset of 23 Caribbean reef sharks and 15 tiger sharks which were passively monitored in two arrays with a combined total of 13 acoustic receivers. We used acoustic telemetry to advance our understanding of the ecology of such sharks, namely Caribbean reef sharks ( Carcharhinus perezi) and tiger sharks ( Galeocerdo cuvier), over two discrete islands (New Providence and Great Exuma) varying in human activity level, over 2 years. Little is known, however, about the long-term behavior and space use of sharks within this protected area, particularly among reef-associated sharks for which the sanctuary presumably offers the most benefit. The Commonwealth of the Bahamas represents a long-term MPA for sharks, following the banning of commercial longlining in 1993 and subsequent designation as a shark sanctuary in 2011. Among MPAs, a large percentage has been created with the implicit goal of protecting shark populations, including 17 shark sanctuaries which fully protect sharks throughout their jurisdiction. Marine protected areas (MPAs) have emerged as potentially important conservation tools for the conservation of biodiversity and mitigation of climate impacts. 9Red Sea Research Center and Computational Biosciences Research Center, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia.Shedd Aquarium, Chicago, IL, United States Haerther Center for Conservation and Research, John G. 7Rosenstiel School of Marine and Atmospheric Science, University of Miami, Miami, FL, United States.6Department of Environmental Conservation, University of Massachusetts Amherst, Amherst, MA, United States.5Perry Institute for Marine Science, Waitsfield, VT, United States.4Department of Biology, Carleton University, Ottawa, ON, Canada. ![]() 3Department of Biological Sciences, Institute of Environment, Florida International University, North Miami, FL, United States.2School of Marine and Atmospheric Sciences, Stony Brook University, Stony Brook, NY, United States.1Beneath the Waves, Herndon, VA, United States. ![]() Griffin 6, Neil Hammerschlag 7, Sami Kattan 1, Yannis P.
