Although some organisms have moved to higher elevations and latitudes in response recent climate change, there is little consensus regarding the capacity of different species track rapid change via range shifts. Understanding species' abilities shift ranges has important implications for assessing extinction risk predicting future community structure. At an expanding front, colonization rates are determined jointly by reproduction dispersal. In addition, establishment viable populations...
Salmon life histories are finely tuned to local environmental conditions, which intimately linked climate. We summarize the likely impacts of climate change on physical environment salmon in Pacific Northwest and discuss potential evolutionary consequences these changes, with particular reference Columbia River Basin spring/summer Chinook (Oncorhynchus tshawytscha) sockeye nerka) salmon. possible responses migration spawning date egg juvenile growth development rates, thermal tolerance,...
Abstract The physical and ecological ‘fingerprints’ of anthropogenic climate change over the past century are now well documented in many environments taxa. We reviewed evidence for phenotypic responses to recent fish. Changes timing migration reproduction, age at maturity, juvenile migration, growth, survival fecundity were associated primarily with changes temperature. Although these traits can evolve rapidly, only two studies attributed formally evolutionary mechanisms. correlation‐based...
Abstract Widespread declines in Atlantic and Pacific salmon ( Salmo salar Oncorhynchus spp.) have tracked recent climate changes, but managers still lack quantitative projections of the viability any individual population response to future change. To address this gap, we assembled a vast database survival other data for eight wild populations threatened Chinook O. tshawytscha ). For each population, evaluated impacts at all life stages modeled trajectories forced by global model...
The prevalence and intensity of marine heatwaves is increasing globally, disrupting local environmental conditions. individual population-level impacts prolonged on species have recently been demonstrated, yet whole-ecosystem consequences remain unexplored. We leveraged time series abundance data 361 taxa, grouped into 86 functional groups, from six long-term surveys, diet information a new database, previous modeling efforts, to build two food web networks using an extension the popular...
As the climate warms, many species are moving to higher latitudes and elevations. However, range shifts can be caused by factors. These factors unknown in most cases. The specific role of these dynamics needs study better predict future consequences global warming. This case evaluates whether warming is driving northward expansion a skipper butterfly (Atalopedes campestris). Recently colonized areas have warmed 2–4°C over past 50 years. To assess importance change for population persistence...
Hundreds of species are shifting their ranges in response to recent climate warming. To predict how continued warming will affect the potential, or "bioclimatic range," a skipper butterfly, we present population‐dynamic model range shift which population growth is function temperature. We estimate parameters this using previously published data for Atalopedes campestris. Summer and winter temperatures rate independently therefore interact as potential range‐limiting factors. Our predicts...
Major ecological realignments are already occurring in response to climate change. To be successful, conservation strategies now need account for geographical patterns traits sensitive change, as well threats species-level diversity. As part of an effort provide such information, we conducted a vulnerability assessment that included all anadromous Pacific salmon and steelhead (Oncorhynchus spp.) population units listed under the U.S. Endangered Species Act. Using expert-based scoring system,...
Environmental change can shift the phenotype of an organism through either evolutionary or nongenetic processes. Despite abundant evidence phenotypic in response to recent climate change, we typically lack sufficient genetic data identify role evolution. We present a method using characterize hypothesized natural selection and environmentally driven shifts (plasticity). modeled historical environmental predictors interannual variation mean population multivariate state-space model framework....
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 Habitat conditions mediate the effects of climate, so neighboring populations with differing habitat may differ in their responses to climate change. We have previously observed that juvenile survival Snake River spring/summer Chinook salmon is strongly correlated summer temperature some and fall streamflow others. Here, we explore potential differential viability four these changes might result from First, linked predicted air precipitation several General Circulation Models a...
Summary We explored differential population responses to climate in 18 populations of threatened spring–summer Chinook salmon Onchorynchus tshawytscha the Salmon River basin, Idaho. Using data from a long‐term mark–release–recapture study juvenile survival, we found that fall stream flow is best predictor average survival across all populations. To determine whether responded similarly climate, used cluster analysis group had similar annual fluctuations survival. The grouped into four...
Dams designed for hydropower and other purposes alter the environments of many economically important fishes, including Chinook salmon (Oncorhynchus tshawytscha). We estimated that dams on Rogue River, Willamette Cowlitz Fall Creek decreased water temperatures during summer increased fall winter. These thermal changes undoubtedly impact behavior, physiology, life histories salmon. For example, relatively high winter should speed growth development, leading to early emergence fry....
1. The size individuals attain reflects complex interactions between food availability and quality, environmental conditions ecological interactions. A statistical interaction temperature the density of conspecifics is expected to arise from various dynamics, including bioenergetic constraints, if population affects mean consumption rate or activity level. Density effects on behaviour size-selective predation could also generate this pattern. This plays an important role in models,...
Introduction Understanding how abundance, productivity and distribution of individual species may respond to climate change is a critical first step towards anticipating alterations in marine ecosystem structure function, as well developing strategies adapt the full range potential changes.

The Northern California Current is a highly productive marine upwelling ecosystem that economically and ecologically important. It home to both commercially harvested species those are federally listed under the U.S. Endangered Species Act. Recently, there has been global shift from single-species fisheries management ecosystem-based management, which acknowledges more complex dynamics can reverberate through food web. Here, we have integrated new research into an end-to-end model (i.e.,...
ABSTRACT Effectively modeling the impact of climate change on any population requires careful consideration diverse pressures. Potential changes in interactions with other species must be accounted for. As communities reassemble and shifts abundance distribution cascade throughout ecosystems, cumulative impacts conservation concern need to explicitly examined. A structured qualitative analysis alternative responses across food web can play a valuable role design interpretation quantitative...
Abstract Aquatic species are threatened by climate change but have received comparatively less attention than terrestrial species. We gleaned key strategies for scientists and managers seeking to address in aquatic conservation planning from the literature existing knowledge. 3 categories of effort that rely on scientific analysis particular application under U.S. Endangered Species Act (ESA): assessment overall risk a species; long‐term recovery planning; evaluation effects specific actions...
In 2015, the Pacific marine heat wave, low river flows, and record high water temperatures in Columbia River Basin contributed to a near-complete failure of adult migration endangered Snake sockeye salmon (Oncorhynchus nerka, NOAA Fisheries 2016). These extreme weather events may become new normal due anthropogenic climate change, with catastrophic consequences for species. Existing pressures amplify vulnerability but these potential synergies have rarely been quantified. We examined factors...
