iMARES (Integrated Marine Ecosystem Assessments)

Grup de recerca IMARES ICM CSIC

Molecular Physiology and Biotechnology of Marine Organisms

The aim of iMARES is to develop excellent evidence-based science of integrated marine socio-ecological systems with the final goal of informing environmental and conservation policies for a transformative management of the oceans, encompassing the pelagic, neritic, and coastal environments. We foster a systemic understanding of the patterns and processes driving marine ecosystem dynamics (encompassing past, present and future dynamics) under the influence of cumulative stressors, and their consequences for ecosystem functioning and nature-contributions to people, framed within socioecological perspectives. We use this knowledge to propose and evaluate management strategies that support ocean conservation and the blue economy, and foster the necessary transition towards an ecosystem-based marine spatial planning.

Within iMARES we study key species, which integrate changes across marine food webs and serve to monitor ongoing ecological shifts; keystone species that play a fundamental role in structuring and maintaining ecosystem functioning; and vulnerable species that are particularly threatened and at risk of decline. We study these species (both commercial and recreational) within their communities, food webs, and ecosystem contexts, and we assess their responses to environmental factors (e.g., climate-driven environmental changes, extreme events) and human activities (e.g., fishing, invasive species, pollution, pathogens). Our research approaches range from fieldwork expeditions, to laboratory work, data analyses and modelling. We develop and apply modelling methods using qualitative, statistical and mechanistic modelling approaches. We pioneer the use of trophic and molecular markers, emerging pollutants and pathogens, bio-logging, and remote sensing. 

iMARES researchers are at the core of the new Scientific-Technical Service (STS) of ICM-CSIC: the Trophic Ecology and Connectivity (TEC), which focuses on the study of ecological interactions and functional connectivity in marine ecosystems. Its goal is to bridge the gap between understanding ecosystem structure and its functions by characterising trophic relationships and species and habitats connectivity and how these patterns vary across space and time. This approach enables the assessment of ecosystem vulnerability to climatic and anthropogenic disturbances, the quantification of key species' roles (including humans), and the prediction of future dynamics based on historical data. iMARES members are also actively involved in several multi-stakeholders’ participatory groups, helping to ensure that the best available science informs a wide range of decision-making processes.  

Since 2022, iMARES is a research group recognized by the Generalitat de Catalunya (AGAUR-SGR-Cat 2021). Every year, the group hosts several Master and undergraduate students, and welcomes numerous visiting national and international scientists. The group currently conducts several national and international basic science and applied projects.

    Highlights

     

    • Interdisciplinary research on marine socio-ecological systems
      iMARES conducts integrated research that connects marine ecology, environmental change, and human activities. This socio-ecological perspective allows the group to understand how ecosystems function and how societal uses of the ocean influence ecological dynamics and ecosystem services.
       
    • Focus on transformative science for sustainability
      The research agenda of iMARES is designed to support transformative change in marine management, aligning biodiversity conservation with sustainable use of marine resources and human well-being with a One Health perspective. Our work contributes to global sustainability frameworks such as the IPBES concept of “good quality of life.” 
       
    • Integration of basic and applied research
      The group combines fundamental ecological research with applied studies that directly address real-world challenges. By linking scientific understanding with management applications, iMARES ensures that research outputs can effectively inform marine spatial planning, fisheries management, and conservation strategies. 
       
    • Advanced modelling and analytical approaches
      iMARES develops and applies a wide range of modelling techniques, including statistical, mechanistic, and ecosystem models. These approaches enable the group to analyse complex ecological and socio-economic processes, explore future scenarios, and support evidence-based decision making under environmental change. iMARES’ research is complemented by cutting-edge empirical methods made accessible through the dedicated Trophic Ecology and Connectivity Scientific and Technical Service.
       
    • Development of open tools and digital workflows
      The group prioritises the development of open-access tools, datasets, and semi-automated workflows that make scientific knowledge more accessible and reproducible to different stakeholders, such as scientists, managers, and others, enabling to apply robust evidence in research, monitoring, and policy contexts. 
       
    • Strong science-to-policy orientation
      A key strength of iMARES is its ability to translate scientific evidence into practical tools and knowledge that inform public policies. The group produces indicators, assessments, and decision-support tools that support policymakers, managers, and international organisations in marine conservation and planning. 
       
    • Leadership in international scientific initiatives and assessments
      Members of iMARES hold leading roles in major global science-policy processes, including IPBES assessments, the UN World Ocean Assessment, and ICES scientific working groups. This involvement demonstrates the group’s scientific credibility and influence in shaping international marine policy and research agendas. 
       
    • Strong capacity to attract competitive funding
      The group has successfully secured a large portfolio of national, European, and international research projects. This strong funding record reflects both the scientific excellence of the team and its ability to lead and coordinate complex collaborative initiatives. 
       
    • High scientific productivity and impact
      iMARES maintains a high level of research output, including numerous peer-reviewed publications, policy reports, and scientific presentations. These outputs contribute to advancing marine science while ensuring that research findings reach both academic and policy audiences. 
       
    • Extensive international collaborations
      The group collaborates with a wide range of leading universities, research centres, and global scientific networks. These partnerships foster interdisciplinary research, knowledge exchange, and participation in international initiatives addressing global marine challenges. 
       
    • Commitment to training early-career researchers
      iMARES provides strong mentoring and training opportunities for bachelor’s, master’s and PhD’s students and postdoctoral researchers. Through supervision, training programmes, and participation in projects, the group actively supports the development of the next generation of marine scientists. 
       
    • Active engagement with stakeholders and society
      The group works closely with policymakers, blue food system actors, conservation organisations, and coastal communities. By co-producing knowledge with societal actors, iMARES promotes practical solutions and socially relevant research outcomes. 
       
    • Commitment to open science and FAIR principles
      iMARES follows FAIR-by-design principles to ensure that research outputs are findable, accessible, interoperable, and reusable. This approach strengthens transparency, reproducibility, and the long-term value of scientific data and tools.
       
    • Inclusive and gender-balanced research environment
      Gender balance and inclusiveness are actively promoted within the group’s organisational structure and activities. This commitment contributes to a supportive research environment and integrates gender and diversity perspectives where relevant in research and stakeholder engagement.
       
    • Strong outreach and science communication activities
      iMARES actively disseminates knowledge through public events, workshops, training courses, educational programmes, and media engagement. The group also shares its work with society through social media, Science Week initiatives, the International Day of Women and Girls in Science and a wide range of talks and activities in schools. These outreach activities help bridge the gap between science and society while promoting ocean literacy and awareness.
