Seagrass meadows and mangrove forests are ecologically and economically important systems that are increasingly threatened by anthropogenic activity. This study used a non-invasive method, baited remote underwater video systems (BRUVS), to observe mobile marine vertebrates in the seagrass-mangrove ecotone in North and South Bimini, the only area where mangroves remain in the northwestern Bahamas. An extensive area of mangroves and seagrass was removed for coastal development in North Bimini, where a marine protected area, the North Bimini Marine Reserve (NBMR), has been under consideration for decades. This research applied principles of seascape ecology to assess species abundance, diversity, and richness of marine fauna at 102 BRUVS deployment sites to answer the central research question, how does seascape composition and configuration influence mobile marine vertebrates in seagrass meadows adjacent to mangrove and non-mangrove habitats in Bimini, Bahamas? Findings highlighted the importance of the seagrass-mangrove ecotone for marine vertebrates (teleosts, elasmobranchs, and reptiles) with greater species abundance, diversity, and richness associated with denser seagrass near mangrove-lined shores.
