Assessing the effects of coral reef habitat and marine protected areas on threatened megafauna using aerial surveys

Abstract: Overfishing and habitat degradation are major threats to marine megafauna worldwide. Marine protected areas (MPAs) are effective spatial conservation tools for reducing anthropogenic pressures on threatened species but their benefits for megafauna are still debated. While the effects of MPAs on species abundances are widely reported, few studies have simultaneously investigated the confounding effect of habitat. This study aimed at disentangling the effects of coral reef habitat and spatial protection on megaf… Show more

“…Coasts 2023, 3 abundance such as percent cover [6][7][8], though more intensive computing tools requiring resources and expertise are also being developed [9][10][11]. Our digital approach differs from existing tools by providing a resource-efficient means to map the positions and measure the sizes of individual organisms within video transects, therefore enabling characterizations of community structure in terms of species' composition, abundance, and size distribution at each observation, and estimations of species' demographic performances in survival, growth, reproduction, and migration between consecutive surveys [12].…”
