Using baited remote underwater videos to characterize chondrichthyan communities

Using baited remote underwater videos (BRUVs) to characterize chondrichthyan communities in a global biodiversity hotspot Geoffrey J. Osgood, Meaghen E. McCord, Julia K. Baum ABSTRACT: Threatened chondrichthyan diversity is high in developing countries where scarce resources, limited data, and minimal stakeholder support often render conservation efforts challenging. As such, data on many species, including many
