Policy must anticipate conflict over geographic shifts
Projections of climate change impacts on marine ecosystems have revealed long-term declines in global animal biomass and unevenly distributed fisheries. Here we apply an enhanced suite ecosystem models from the Fisheries Marine Ecosystem Model Intercomparison Project (Fish-MIP), forced by new-generation Earth system model outputs Phase 6 Coupled (CMIP6), to provide insights into how projected will affect future ocean ecosystems. Compared with previous generation CMIP5-forced Fish-MIP...
How can ocean governance and science be made more equitable effective? The majority of the world's ocean-dependent people live in low to middle-income countries tropics (i.e., 'tropical majority'). Yet agenda is set largely on basis scientific knowledge, funding, institutions from high-income nations temperate zones. These externally driven approaches undermine equity effectiveness current solutions hinder leadership by tropical majority, who are well positioned activate evidence-based...
Climate change is warming the ocean and impacting lower trophic level (LTL) organisms. Marine ecosystem models can provide estimates of how these changes will propagate to larger animals impact societal services such as fisheries, but at present vary widely. A better understanding what drives this inter-model variation improve our ability project fisheries other into future, while also helping identify uncertainties in process understanding. Here, we explore mechanisms that underlie...
Abstract Climate change is shifting the distribution of shared fish stocks between neighboring countries’ Exclusive Economic Zones (EEZs) and high seas. The timescale these transboundary shifts determines how climate will affect international fisheries governance. Here, we explore this by coupling a large ensemble simulation an Earth system model under emission scenario to dynamic population model. We show that 2030, 23% have shifted 78% world's EEZs experienced at least one stock. By end...
Climate change is expected to profoundly affect key food production sectors, including fisheries and agriculture. However, the potential impacts of climate on these sectors are rarely considered jointly, especially below national scales, which can mask substantial variability in how communities will be affected. Here, we combine socioeconomic surveys 3,008 households intersectoral multi-model simulation outputs conduct a sub-national analysis agriculture 72 coastal across five Indo-Pacific...
Scientific bottom-trawl surveys are ecological observation programs conducted along continental shelves and slopes of seas oceans that sample marine communities associated with the seafloor. These report taxa occurrence, abundance and/or weight in space time, contribute to fisheries management as well population biodiversity research. Bottom-trawl all over world represent a unique opportunity understand ocean biogeography, macroecology, global change. However, combining these data together...
There is an urgent need for models that can robustly detect past and project future ecosystem changes risks to the services they provide people. The Fisheries Marine Ecosystem Model Intercomparison Project (FishMIP) was established develop model ensembles projecting long-term impacts of climate change on fisheries marine ecosystems while informing policy at spatio-temporal scales relevant Inter-Sectoral Impact (ISIMIP) framework. While contributing FishMIP have improved over time, large...
Abstract The immense challenges associated with realizing ocean and coastal sustainability require highly skilled interdisciplinary marine scientists. However, the barriers experienced by early career researchers (ECRs) seeking to address these challenges, support required overcome those barriers, are not well understood. This study examines perspectives of ECRs on opportunities build research capacity in science. We engaged 23 current former graduate students postdoctoral fellows a policy...
Rebuilding overexploited marine populations is an important step to achieve the United Nations' Sustainable Development Goal 14-Life Below Water. Mitigating major human pressures required rebuilding goals. Climate change one such key pressure, impacting fish and invertebrate by changing their biomass biogeography. Here, combining projection from a dynamic bioclimate envelope model with published estimates of status exploited catch-based analysis, we analyze effects different global warming...
We find ourselves at a critical crossroads for the future governance of high seas, but perceived remoteness global ocean creates psychological barrier people to engage with it. Given challenges overexploitation, inequitable access and other sustainability equity concerns, current mechanisms are not fit-for-purpose. This decade offers opportunities direct impact on governance, however, triggering transformation how we use protect half our planet requires concerted effort that is guided by...
Climate change is affecting ocean temperature, acidity, currents, and primary production, causing shifts in species distributions, marine ecosystems, ultimately fisheries. Earth system models simulate climate impacts on physical biogeochemical properties of future oceans under varying emissions scenarios. Coupling these simulations with an ensemble global ecosystem indicates decreasing fish biomass warming. However, regional projections remain much more uncertain. Here, we employ CMIP5 CMIP6...
Climate change could irreversibly modify Southern Ocean ecosystems. Marine ecosystem model (MEM) ensembles can assist policy making by projecting future changes and allowing the evaluation assessment of alternative management approaches. However, projected in total consumer biomass from Fisheries Ecosystem Model Intercomparison Project (FishMIP) global MEM ensemble highlight an uncertain for Ocean, indicating need a region-specific ensemble. A large source uncertainty originates Earth system...
Regulatory boundaries and species distributions often do not align. This is especially the case for marine crossing multiple Exclusive Economic Zones (EEZs). Such movements represent a challenge fisheries management, as policies tend to focus at national level, yet international collaborations are needed maximize long-term ecological, social economic benefits of shared species. Here, we combined spatial delineation EEZs global level identify number commercially exploited that between...

Abstract In ocean areas beyond national jurisdiction, various legal regimes and governance structures result in diffused responsibility create challenges for management. Here we show those are set to expand with climate change driving increasing overlap between eastern Pacific tuna fisheries the emerging industry of deep-sea mining. Climate models suggest that distributions will shift coming decades. Within Clarion-Clipperton Zone Ocean, a region containing 1.1 million km 2 mining...
Abstract No-take marine protected areas (No-take MPAs) are considered as a major tool for conserving biodiversity and ecosystem services. MPAs can also contribute to climate adaptation exploited fish stocks. Meanwhile, many stocks in the world overfished management institutions developing plans rebuild them. Understanding potential effects of no-take on under change help develop strategies climate-resilient stock rebuilding. Here, using linked climate-fish-fishing model, we undertake...
Abstract Emerging fishing activity due to melting ice and poleward species distribution shifts in the rapidly‐warming Arctic Ocean challenges transboundary management requires proactive governance. A 2021 moratorium on commercial high seas provides a 16‐year runway for improved scientific understanding. Given substantial knowledge gaps, characterizing areas of highest uncertainty is key first step. Marine ecosystem model ensembles that project future fish distributions could inform...
Humans have transformed ecosystems through habitat modification, harvesting, species introduction, and climate change. Changes in distribution composition are often thought to induce biotic homogenization, defined as a decline spatial beta diversity time. However, it is unclear whether homogenization common ocean if changes exhibit linear or more complex dynamics. Here, we assessed patterns of its converse (differentiation) across than 175,000 samples 2,006 demersal fish from 34 regions...
Climate change is altering species’ distributions globally. Increasing frequency of extreme weather and climate events (EWCEs), including heat waves, droughts, storms, floods, fires, one the hallmarks change. These can trigger rapid shifts in by impacting dispersal, establishment, survival organisms. Despite species redistribution being widely studied response to longer-term trends change, few studies consider contribution EWCEs range shifts. With ecologically, economically, culturally...
