Marine conserved areas (MCAs) can provide a range of ecological and socio-economic benefits, including climate change mitigation from the protection enhancement natural carbon storage. Canada's MCA network is expanding to encompass 30% its Exclusive Economic Zone by 2030. At present, aims integrate protecting coastal vegetated blue ecosystems (saltmarsh, seagrass, kelp). Here, we argue that incorporating unvegetated seabed sediments could bring similar benefits. Seabed store and/or accumulate high densities organic carbon, due their large spatial extent, contain stores orders magnitude larger than habitats. We estimate currently designated MCAs only 10.8% sediment stocks on continental margin, 13.4% with densities. Proposed would cover an additional 8.8% 6.1% total areas, respectively. identify set high-priority for future research potential protection, ranking importance based stocks, proxies lability, ecological/biological significance. The incorporation into networks support preventing releases stored carbon.

ABSTRACT Under accelerating threats from climate‐change impacts, marine protected areas (MPAs) have been proposed as climate‐adaptation tools to enhance the resilience of ecosystems. Yet, debate persists whether and how MPAs may promote climate shocks. Here, we use 38 years satellite‐derived kelp cover empirically test a network 58 temperate coastal in Central Southern California enhances resistance forest ecosystems to, their recovery from, unprecedented 2014–2016 heatwave regime that occurred region. We also leverage 22‐year time series subtidal community surveys mechanistically understand trophic cascades explain emergent patterns within MPAs. find fully significantly forests' heatwaves California, but not California. Differences regional responses are partly explained by three‐level interactions comprising kelp, urchins, predators urchins. Urchin densities lower during after heatwave, while abundances main predators—lobster sheephead—are higher. In region without lobster or sheephead, there is no significant difference urchin current predator, sea otter, statewide. Our analyses show can be effective tools, ability extreme events depends upon region‐specific environmental interactions. As nations progress protect 30% oceans 2030, scientists managers should consider protection will increase impacts given local ecological contexts, what additional measures needed.

The Punta Coles Natural Reserve (PCNR), located on the southern coast of province Ilo, Moquegua Region, Peru, houses an area rich in marine biodiversity which is composed natural banks benthic invertebrates, constitute potential and dynamic fishery commercial interest for artisanal fishermen that impact area. To mitigate this impact, all stakeholders need to know, understand, value, balance dependence with ecosystem its preservation promotion sustainable fishing. Along these lines, components studied are bathymetry, lithology, tapestry bioengineers make up reserve’s seabed. Mapping complexity habitat seabed was developed basis integrated analysis multibeam bathymetric data, geoscientific information associated antecedents PCNR, sediment maps seabed, subtidal sedimentological texture, photographic records. characterization granulometry sediments PCNR were determined according Udden–Wentworth classification criterion (Φ). utility GPSMAP 178C echosounder interpretation stands out. kriging interpolation method used extrapolate characteristics habitat, suitable large areas sea. As a result, three habitats derived mapped, structures (bioengineers), namely, “subtidal kelps” (Lessonia trabeculata), “mussels” (Aulacomya atra), “red sea squirt” (Pyura chilensis), mainly sedimentary rock mixed substrates. In sand substrate, algae found lesser extent. results show study conceptual model summarizes understanding ecology prospects sustainability profitable, ecoefficient fishing activities Peru.
