However, little is known about the marine ecosystems of this diverse region. Much of the coastline consists of soft sediment exposed to strong wave action. Three major hard bottom habitat types define this region, including: 1) coral reefs around Isla del Caño Biological Reserve, a no-take marine protected area (MPA) of 52 km2, 2) coastal rocky reefs and islets along the peninsula, including Corcovado National Park, and 3) submerged pinnacles just outside the Isla del Caño MPA. Average coral cover at Isla del Caño was 21%, composed primarily of Porites lobata and Pocillopora elegans. In contrast, coastal rocky reefs were dominated by turf algae (39.8%) and macroalgae (20.7%) with low coral cover (1.1%). Submerged pinnacles were dominated by crustose coralline algae (33.3%) and erect coralline ...

Tagged fish ranged over a wide geographic area between 1°S to 17°N and 125 to 154°W. Both blue marlin and sailfish exhibited fidelity to the PNMS; however, they dispersed more than 1000 km before returning. The monitoring periods of yellowfin tuna were insufficient to evaluate their long-term movements, but their dispersal from Palau's EEZ occurred in all directions, up to distances of 2010 km. The space use of this pelagic species assemblage overlapped with two bodies of international waters, six EEZs, and the Western and Central Pacific Fisheries Commission's management units seven and three of the western Pacific Ocean. Our results add to the knowledge base on the movements of pelagic species in the PNMS and highlight the need for additional rese...

We use distribution data for 1,338 commercially important fisheries stocks around the world to model how MPAs in different locations would affect catch. We show that strategically expanding the existing global MPA network by just 5% can improve future catch by at least 20%. Our work demonstrates that a global network of MPAs designed to improve fisheries productivity can substantially increase future catch, enabling synergistic conservation and food provisioning.
