Shortfalls in the protection of Important Shark and Ray Areas undermine shark conservation efforts in the Central and South American Pacific
Global biodiversity targets require nations to designate 30 % of their marine waters as protected areas by 2030. Sharks, rays, and chimaeras (hereafter ‘sharks’) are key components of aquatic ecosystems; however, over a third are globally threatened with extinction. Across the Central and South American Pacific Ocean region, we (i) assessed trends in Marine Protected Area (MPA) expansion and extent across the 12 nations of the region; (ii) quanti…
Local diver knowledge reveals decline in scalloped hammerhead sharks (Sphyrna lewini) at seamounts in the southwestern Gulf of California
Assessing opportunities to support coral reef climate change refugia in MPAs
Coral reef refugia are habitats which possess physical, biological and ecological characteristics that make them likely to be relatively resilient to future climate change. Identification of refugia locations will be important to ensure suitable marine conservation planning is undertaken to protect sites where coral ecosystems will be better preserved now and in the future. This paper presents (1) a review of current knowledge of the oceanographi…
