“…In addition, English sole were less abundant in estuaries with greater land cover stress. Our novel findings build upon regional field studies, experimental manipulation, meta-analyses, models, reviews, and studies focusing on a single stressor or species over broad spatial and temporal components that have shown stressors can threaten fishes (Barcel o et al, 2016;Cheng et al, 2015;Crain et al, 2008;Harborne et al, 2017;Hughes et al, 2015;Minello, Able, Weinstein, & Hays, 2003;Munsch, Cordell, & Toft, 2017;Vinebrooke et al, 2004;Vye et al, 2015). Estuaries are increasingly drawing conservation attention because of recognition that they serve as critical habitats for fish (Beck et al, 2001), and we demonstrate on a coast-wide basis that such efforts are for good reason.…”

“…Estuaries and coasts are among the ecosystems that are immensely threatened yet valuable to people (Costanza et al, 1997). Our understanding of global change in estuaries and coasts is derived from regional field studies (e.g., hypoxia effects on flatfish in Elkhorn Slough, CA, USA; Hughes et al, 2015), small-scale experiments (e.g., additive, antagonistic, or synergistic stressor effects on macroalgae; Vye, Emmerson, Arenas, Dick, & O'Connor, 2015), meta-analyses (e.g., synthesizing interactive and cumulative effects of stressors; Crain, Kroeker, & Halpern, 2008), conceptual and theoretical models (e.g., Vinebrooke et al, 2004), and reviews (e.g., syntheses of multiple stressors on coral reefs; Harborne, Rogers, Bozec, & Mumby, 2017).

Studies that examine broad temporal and spatial scales tend to be conducted in freshwater or terrestrial ecosystems (e.g., Ceballos, Ehrlich, & Dirzo, 2017;Esselman et al, 2011), emphasize single species across larger geographic gradients (e.g., Cheng et al, 2015) or a single stressor across longer temporal gradients (e.g., Barcel o, Ciannelli, Olsen, Johannessen, & Knutsen, 2016).…”

A key step in identifying global change impacts on species and ecosystems is to quantify effects of multiple stressors. To date, the science of global change has been dominated by regional field studies, experimental manipulation, meta-analyses, conceptual models, reviews, and studies focusing on a single stressor or species over broad spatial and temporal scales. Here, we provide one of the first studies for coastal systems examining multiple stressor effects across broad scales, focused on the nursery function of 20 estuaries spanning 1,600 km of coastline, 25 years of monitoring, and seven fish and invertebrate species along the northeast Pacific coast. We hypothesized those species most estuarine dependent and negatively impacted by human activities would have lower presence and abundances in estuaries with greater anthropogenic land cover, pollution, and water flow stress. We found significant negative relationships between juveniles of two of seven species (Chinook salmon and English sole) and estuarine stressors. Chinook salmon were less likely to occur and were less abundant in estuaries with greater pollution stress. They were also less abundant in estuaries with greater flow stress, although this relationship was marginally insignificant. English sole were less abundant in estuaries with greater land cover stress. Together, we provide new empirical evidence that effects of stressors on two fish species culminate in detectable trends along the northeast Pacific coast, elevating the need for protection from pollution, land cover, and flow stressors to their habitats. Lack of response among the other five species could be related to differing resistance to specific stressors, type and precision of the stressor metrics, and limitations in catch data across estuaries and habitats. Acquiring improved measurements of impacts to species will guide future management actions, and help predict how estuarine nursery functions can be optimized given anthropogenic stressors and climate change scenarios.

“…Differing abiotic conditions may enhance or compromise these traits (Krassoi et al, 2008;Ruesink, 2007). Environmental context, thus, plays a major role in shaping communities and species interactions and is often neglected when impacts of invaders are quantified (Bruno, Stachowicz, & Bertness, 2003;Papacostas et al, 2017;Vye, Emmerson, Arenas, Dick, & O'Connor, 2015).…”

Competition between co‐occurring invasive and native consumers switches between habitats

The introduction of a non‐native species frequently has adverse direct effects on native species. The underlying mechanisms, however, often remain unclear, in particular where native and invasive species are taxonomically similar. We found evidence of direct competitive interactions between a globally distributed invasive species (the Pacific oyster, Magallana gigas) and its native counterpart (the European oyster, Ostrea edulis). We also discovered that the competitive outcome differed between different habitat types and orientation by identifying context‐dependent responses driven by environmental conditions and stress (i.e. intertidal compared to subtidal habitats; and vertical versus horizontal substratum). This is particularly important because the European oyster is threatened, or in decline, throughout most of its range, and restoration efforts are underway in many regions. We combined experimental manipulations and stable isotope analysis (SIA) to identify the direct effects of competition and the mechanisms by which the invasive and native species compete. We identified negative effects of the invasive species on the native oyster, but these were limited to the subtidal habitat (lower stress environment) and determined by substratum orientation (habitat structure). Crucially, we found that effects of the invasive species on the native species were not always negative and under certain conditions (e.g. on vertical substrata) were positive. Shifts in isotopic niches of both species when co‐occurring, alongside mixing models, indicate that exploitative competition for food is most likely to underpin niche partitioning between both species. We have identified different foraging strategies under different contexts, and our findings highlight the importance of exploitative competition as a driving mechanism behind the co‐occurrence of two seemingly functionally similar consumers. The combination of experimental manipulations with SIA is a powerful tool, and we illustrate how this approach should be incorporated, into multiple environmental contexts at appropriate scales, to more accurately predict impacts of the spread of invasive species on native communities.

Kelp is a non-taxonomic term that refers to ecologically important canopy-forming large brown macroalgae, usually of the Order Laminariales (although other functionally similar macroalgae are sometimes included; Fraser, 2012), that inhabit hard substrata of the seafloor (Figure 1). Kelp play a key role in primary and secondary productivity through photosynthesis and the export of dissolved and particulate organic material in coastal ecosystems (Paine et al., 2021;Takao et al., 2015), where a large proportion of kelp production enters coastal food webs mainly as detritus (Krause-Jensen
