Marine protected areas (MPAs) that exclude fishing have been shown repeatedly to enhance the abundance, size, and diversity of species. These benefits, however, mean little most marine species, because individual typically are small. To meet larger-scale conservation challenges facing ocean ecosystems, several nations expanding benefits by building networks areas. Doing so successfully requires a detailed understanding ecological physical characteristics ecosystems responses humans spatial...
Management and conservation can be greatly informed by considering explicitly how environmental factors influence population genetic structure. Using simulated larval dispersal estimates based on ocean current observations, we demonstrate explicit consideration of frequency exchange larvae among sites via advection fundamentally change the interpretation empirical structuring as compared with conventional spatial analyses. Both difference were uncorrelated Euclidean distance between sites....
Marine spatial planning (MSP) is an emerging responsibility of resource managers around the United States and elsewhere. A key proposed advantage MSP that it makes tradeoffs in use sector (stakeholder group) values explicit, but doing so requires tools to assess tradeoffs. We extended tradeoff analyses from economics simultaneously multiple ecosystem services they provide sectors using a robust, quantitative, transparent framework. used framework potential conflicts among offshore wind...
Simulation models are widely used to represent the dynamics of ecological systems. A common question with such is how changes a parameter value or functional form in model alter results. Some authors have chosen answer that using frequentist statistical hypothesis tests (e.g. ANOVA). This inappropriate for two reasons. First, p‐values determined by power (i.e. replication), which can be arbitrarily high simulation context, producing minuscule regardless effect size. Second, null no...
Abstract Marine species frequently show weak and/or complex genetic structuring that is commonly dismissed as ‘chaotic’ patchiness and ecologically uninformative. Here, using three datasets individually feature chaotic patchiness, we demonstrate combining inferences across incorporating environmental data can greatly improve the predictive value of marine population genetics studies on small spatial scales. Significant correlations in patterns microsatellite markers among species, kelp bass...
Triple-bottom-line outcomes from resource management and conservation, where conservation goals equity in social are maximized while overall costs minimized, remain a highly sought-after ideal. However, despite widespread recognition of the importance that equitable distribution benefits or across society can play success, little formal theory exists for how to explicitly incorporate into planning prioritization. Here, we develop implement it three very different case studies California...
Abstract As climatic changes and human uses intensify, resource managers other decision makers are taking actions to either avoid or respond ecosystem tipping points, dramatic shifts in structure function that often costly hard reverse. Evidence indicates explicitly addressing points leads improved management outcomes. Drawing on theory examples from marine systems, we distill a set of seven principles guide effective ecosystems with derived the best available science. These based...
Marine spatial planning (MSP) seeks to reduce conflicts and environmental impacts, promote sustainable use of marine ecosystems. Existing MSP approaches have successfully determined how achieve target levels ocean area for particular uses while minimizing costs but they do not provide a framework that derives analytical solutions in order co-ordinate siting multiple balancing the effects on each sector system. We develop such guiding offshore aquaculture (bivalve, finfish, kelp farming)...
The world's oceans are governed as a system of over 150 sovereign exclusive economic zones (EEZs, ∼42% the ocean) and one large high seas (HS) commons (∼58% with essentially open access. Many high-valued fish species such tuna, billfish, shark migrate around these oceanic regions, which consequence competition across EEZs global race-to-fish on HS, have been over-exploited now return far less than their potential. We address this challenge by analyzing spatial bioeconomic model effects...
Coral reefs worldwide face unprecedented cumulative anthropogenic effects of interacting local human pressures, global climate change and distal social processes. Reefs are also bound by the natural biophysical environment within which they exist. In this context, a key challenge for effective management is understanding how conditions interact to drive distinct coral reef configurations. Here, we use machine learning conduct explanatory predictions on ecosystems defined both fish benthic...
Over the last few decades, offshore wind energy industry has expanded its scope from turbines mounted on foundations driven into seafloor and standing in less than 60 m of water, to floating moored 120 prospecting development ~1,000 water. Since there are prototype mooring systems these deepwater, facilities (OWFs) currently deployed, their effects marine environment speculative. Using available scientific literature concerning appropriate analogs, including fixed-bottom OWFs, land-based...
Abstract Blue food systems are crucial for meeting global social and environmental goals. Both small-scale marine fisheries (SSFs) aquaculture contribute to these goals, with SSFs supporting hundreds of millions people currently expanding in the environment. Here we examine interactions between aquaculture, possible combined benefits trade-offs interactions, along three pathways: (1) resource access rights allocation; (2) markets supply chains; (3) exposure management risks. Analysis 46...
Abstract Some studies suggest that fishery yields can be higher with reserves than under conventional management. However, the economic performance of fisheries depends on profit, not fish yield. The predictions rely intensive fishing pressures between reserves; exorbitant costs harvesting low‐density populations erode profits. We incorporated this effect into a bioeconomic model to evaluate reserve‐based Our results indicate still benefit fisheries, even those targeting species are...
The United States had a $14 billion seafood trade deficit in 2016, importing more than 2.5 million tons of edible fishery products, 90% the value Americans eat (1). Half those imports are from aquaculture (2). Meanwhile, demand for local, fresh, and sustainably produced is growing, absence sufficient local supply to meet this clearly represents lost opportunity sustainability economic growth. Expanded domestic production could promote significant development job creation. Yet, wild-fishery...
A major challenge for coral reef conservation and management is understanding how a wide range of interacting human natural drivers cumulatively impact shape these ecosystems. Despite the importance interactions, methodological framework to synthesize spatially explicit data such lacking. To fill this gap, we established transferable synthesis methodology integrate spatial on environmental anthropogenic reefs, applied case study location-the Main Hawaiian Islands (MHI). Environmental were...
Abstract Food security remains a principal challenge in the developing tropics where communities rely heavily on marine-based protein. While some improvements fisheries management have been made these regions, large fraction of coastal remain unmanaged, mismanaged, or use only crude input controls. These quasi-open-access conditions often lead to severe overfishing, depleted stocks, and compromised food security. A possible fishery approach institution-poor settings is implement fully...
Abstract Burgeoning urbanization, development and human activities have led to reduced opportunities for nature experience in quiet acoustic environments. Increasing noise affects both humans wildlife alike. We experimentally altered human‐caused sound levels a paired study using informational signs that encouraged behaviours week‐on, week‐off blocks on the trail system of Muir Woods National Monument, California, USA test if soundscape influences experiences.

Achieving a blue economy will require reconciling the value of emerging ocean uses with their impacts on seascape and sectors historical access to marine resources areas. To meet this challenge, we developed an analytical framework for conducting spatial planning through tradeoff analysis, applied it prospective offshore wind energy development in ∼974 km2 Morro Bay, California, USA Wind Energy Area (WEA). We generated data layers estimating MW power production fisheries wildlife...
Regulation of fisheries using spatial property rights can alleviate competition for high-value patches that hinders economic efficiency in quota-based, rights-based, and open-access management programs. However, gains erode when delineation constitutes incomplete ownership the resource, thereby degrading its local value promoting overexploitation. Incomplete may be particularly prevalent mobile fishery species. We developed a game-theoretic bioeconomic model representing territorial user...
