“…But introducing more variability between populations in their demographic dynamics (e.g., unstable trends) or in their phenotypic and genotypic composition would open up new perspectives to better address the portfolio effect. However, we found that intrapopulation genetic variance was enhanced in sink populations receiving immigrants from nearby populations, potentially increasing adaptive capacity (Jump et al 2009, Seaborn et al 2021).…”

Despite growing evidence of spatial dispersal and gene flow between salmonid populations, the implications of connectivity for adaptation, conservation, and management are still poorly appreciated. Here, we explore the influence of a gradient of dispersal rates on portfolio strength and eco-evolutionary dynamics in a simulated population network of Atlantic salmon (Salmo salar) by extending a demo-genetic agent-based model to a spatially explicit framework. Our model results highlight a non-linear relationship between dispersal rates and the stability of the metapopulation, resulting in an optimal portfolio effect for dispersal rates around 20%. At local population scale, we also demonstrate phenotypic changes induced by density-dependent effects modulated by dispersal, and a dispersal-induced increase in genetic diversity. We conclude that it is critical to account for complex interactions between dispersal and eco-evolutionary processes and discuss future avenues of research that could be addressed by such modeling approaches to more fully appreciate responses of Atlantic salmon to environmental changes and investigate management actions accordingly.

“…Lastly, socioeconomic adaptive capacity depicts people's ability to anticipate and respond to changes, and to minimize, cope with and recover from climate change impacts (Adger & Vincent, 2005; Cinner et al, 2013). This domain obtained the greatest number of applications in peer‐reviewed literature ( n = 312; Figure 5d,e), partly due to its nature that is closely related to the responses of human systems and its potential to transfer analysis into climate change adaptation effort (Seaborn et al, 2021; Siders, 2019). We identified 53 indicators and classified them into six subgroups, including learning, assets, demographics and social settings, governance, social organizations, and flexibility.…”

Undertaking climate vulnerability assessments (CVAs) on marine fisheries is instrumental to the identification of regions, species, and stakeholders at risk of impacts from climate change, and the development of effective and targeted responses for fisheries adaptation. In this global literature review, we addressed three important questions to characterize fisheries CVAs: (i) what are the available approaches to develop CVAs in various social–ecological contexts, (ii) are different geographic scales and regions adequately represented, and (iii) how do diverse knowledge systems contribute to current understanding of vulnerability? As part of these general research efforts, we identified and characterized an inventory of frameworks and indicators that encompass a wide range of foci on ecological and socioeconomic dimensions of climate vulnerability on fisheries. Our analysis highlighted a large gap between countries with top research inputs and the most urgent adaptation needs. More research and resources are needed in low‐income tropical countries to ensure existing inequities are not exacerbated. We also identified an uneven research focus across spatial scales and cautioned a possible scale mismatch between assessment and management needs. Drawing on this information, we catalog (1) a suite of research directions that could improve the utility and applicability of CVAs, particularly the examination of barriers and enabling conditions that influence the uptake of CVA results into management responses at multiple levels, (2) the lessons that have been learned from applications in data‐limited regions, particularly the use of proxy indicators and knowledge co‐production to overcome the problem of data deficiency, and (3) opportunities for wider applications, for example diversifying the use of vulnerability indicators in broader monitoring and management schemes. This information is used to provide a set of recommendations that could advance meaningful CVA practices for fisheries management and promote effective translation of climate vulnerability into adaptation actions.

“…The metrics of genomic vulnerability estimated here are therefore reliable and have clear implications for not only delineating future conservation units but also informing management decisions of this key long-lived tree species 49 . For instance, the southeastern populations nearby the Korean Peninsula are inferred to be most at risk from future higher temperatures and more intense precipitation.…”

Despite rapid global climate change is posing a huge threat to biodiversity, assessment of the adaptive capacity for most taxa is usually performed as a whole, but lacks to incorporate intraspecific adaptive variation that may play a fundamental role to buffer against future shifting climates. Here we first generated a chromosome-scale genome assembly for Populus koreana, a pioneer and keystone tree species in East Asia temperate forests. We further obtained whole-genome sequences of 230 individuals collected from 24 natural populations, among which we inferred population structure and demographic history of this species. An integration of population genomics and environmental variables was then performed to reveal the genomic basis of local adaptation to diverse climates, and we identify a set of climate-associated single nucleotide polymorphisms (SNPs), insertions-deletions (Indels) and structural variations (SVs), especially numerous adaptive non-coding variants across the genome. We incorporated these variants into the environmental modelling to predict the spatiotemporal responses of P. koreana under climate change. Our results uncover that the southeastern populations near the Korean Peninsula are likely to be most vulnerable to future climates and need further conservation concerns. Collectively, this work improves our understanding of adaptive variation along environmental gradients and adds information on candidate genes that will be useful for future studies of adaptation to extreme environments and for use in breeding programs. The findings highlight the insights that integration of genomic and climate data can shed on future evolutionary adaptive capacities to changing environmental conditions.
