Abstract Marine heatwaves (MHWs)—periods of exceptionally warm ocean temperature lasting weeks to years—are now widely recognized for their capacity disrupt marine ecosystems 1–3 . The substantial ecological and socioeconomic impacts these extreme events present significant challenges resource managers 4–7 , who would benefit from forewarning MHWs facilitate proactive decision-making 8–11 However, despite extensive research into the physical drivers 11,12 there has been no comprehensive...
Cities can host significant biological diversity. Yet, urbanisation leads to the loss of habitats, species, and functional groups. Understanding how multiple taxa respond globally is essential promote conserve biodiversity in cities. Using a dataset encompassing six terrestrial faunal (amphibians, bats, bees, birds, carabid beetles reptiles) across 379 cities on 6 continents, we show that produces taxon-specific changes trait composition, with traits related reproductive strategy showing...
Abstract We assessed bee diversity and abundance in urban areas of Vancouver, British Columbia, Canada, to determine how environments can support bees. Habitats examined were community botanical gardens, wild areas, Naturescape flower beds backyards, traditional backyards. A total 56 species (Hymenoptera), including the genera Andrena Fabr. (Andrenidae), Bombus Latr. (Apidae), Osmia Panzer Megachile (Megachilidae), Halictus Dialictus Pauly (Halictidae), collected. Abundance exhibited strong...
Recent years have seen a rapid expansion in the ability of earth system models to describe and predict physical state ocean. Skilful forecasts ranging from seasonal (3 months) decadal (5-10 years) time scales are now reality. With advance these ocean physics, first generation marine ecological has started emerge. Such potentially great value management living resources for all those who dependent on both nutrition their livelihood; however, this is still field its infancy. We review art...
Marine ecosystem forecasting is an area of active research and rapid development. Promise has been shown for skillful prediction physical, biogeochemical, ecological variables on a range timescales, suggesting potential forecasts to aid in the management living marine resources coastal communities. However, mechanisms underlying forecast skill ecosystems are often poorly understood, many forecasts, especially biological variables, rely empirical statistical relationships developed from...
Spatial distributions of marine fauna are determined by complex interactions between environmental conditions and animal behaviors. As climate change leads to warmer, more acidic, less oxygenated oceans, species shifting away from their historical distribution ranges, these trends expected continue into the future. Correlative Species Distribution Models (SDMs) can be used project future habitat extent for species, with many different statistical methods available. However, it is vital...
Abstract Efforts to manage living marine resources (LMRs) under climate change need projections of future ocean conditions, yet most global models (GCMs) poorly represent critical coastal habitats. GCM utility for LMR applications will increase with higher spatial resolution but obstacles including computational and data storage costs, obstinate regional biases, formulations prioritizing robustness over skill persist. Downscaling can help address limitations, significant improvements are...
Projecting the future distributions of commercially and ecologically important species has become a critical approach for ecosystem managers to strategically anticipate change, but large uncertainties in projections limit climate adaptation planning. Although distribution are primarily used understand scope potential change-rather than accurately predict specific outcomes-it is nonetheless essential where why can give implausible results identify which processes contribute uncertainty. Here,...
Abstract Populations of small pelagic fish are strongly influenced by climate. The inability managers to anticipate environment‐driven fluctuations in stock productivity or distribution can lead overfishing and collapses, inflexible management regulations inducing shifts the functional response human predators, lost opportunities harvest populations, bankruptcies fishing industry, loss resilience food supply. Recent advances dynamical global climate prediction systems allow for sea surface...
Throughout 2014-2016, the California Current System (CCS) was characterized by large and persistent sea surface temperature anomalies (SSTa), which were accompanied widespread ecological socioeconomic consequences that have been documented extensively in scientific literature popular press. This marine heatwave others resulted a heightened awareness of their potential impacts prompted questions about if when they may be predictable. Here, we use output from an ensemble global climate...
Management strategy evaluation (MSE) is a simulation approach that serves as “light on the hill” ( Smith, 1994 ) to test options for marine management, monitoring, and assessment against simulated ecosystem fishery dynamics, including uncertainty in ecological processes observations. MSE has become key method evaluate trade-offs between management objectives communicate with decision makers. Here we describe how why continuing grow from single species one relevant multi-species...
Fishers often target multiple species. More diverse harvest portfolios may reduce income risk, increasing resilience to climate-driven changes in species’ spatial distributions and availability. Moreover, different effects can be observed across vessels response the same shocks stressors, as fishers are heterogeneous. Evaluation of climate risk vessel groups within a particular fishery requires consideration heterogeneous impacts on availability species how such impact substitution behavior....
Abstract Management strategy evaluation (MSE) is the state‐of‐the‐art approach for testing and comparing management strategies in a way that accounts multiple sources of uncertainty (e.g. monitoring, estimation, implementation). can help identify are robust to about life history target species its relationship other food web. Small pelagic fish anchovy, herring sardine) fulfil an important ecological role marine webs present challenges use MSE simulation‐based approaches. This due...
Motivated by a need for climate-informed living marine resource management, increased emphasis has been placed on regional end-to-end modeling frameworks designed to project climate impacts ecosystems and evaluate the efficacy of potential management strategies under changing conditions. The 'Future Seas' was initiated with focus three fisheries (Pacific sardine, swordfish, albacore tuna) in California Current System (CCS). This work leverages suite climate, ocean, ecosystem, economic models...
Forage fishes are key energy conduits that transfer primary and secondary productivity to higher trophic levels. As novel environmental conditions caused by climate change alter ecosystems predator–prey dynamics, there is a critical need understand how forage fish control bottom-up forcing of food web dynamics. In the northeast Pacific, northern anchovy ( Engraulis mordax ) an important species with high interannual variability in population size subsequently impacts foraging reproductive...
Time-area closures are a valuable tool for mitigating fisheries bycatch. There is increasing recognition that dynamic closures, which have boundaries vary across space and time, can be more effective than static at protecting mobile species in environments. We created management strategy evaluation to compare simulated fishery based on the California drift gillnet swordfish fishery, with aimed reducing bycatch of leatherback turtles. tested eight operating models varied distributions, within...
ABSTRACT Changing ocean conditions are leading to spatial redistribution of many marine species, including those that support fisheries. A combination gradual climate trends and shorter‐lived extreme events, such as heatwaves, can change the availability species or stocks fishing ports, impacting communities challenging fisheries management frameworks. Pacific sardine ( Sardinops sagax ) in California Current System currently considered two subpopulations for purposes. They separated from...
