BMC Marine Science is calling for submissions to our Collection on the role of marine genomics and environmental DNA (eDNA) in understanding marine biodiversity and ecosystem dynamics. As marine ecosystems face unprecedented pressures from climate change, pollution, and overfishing, the need for innovative and non-invasive monitoring techniques has become critical. The integration of genomic tools and eDNA methodologies allows researchers to assess biodiversity, track species distribution, and understand community dynamics with unparalleled sensitivity and specificity. By harnessing the power of molecular biology, we can obtain crucial insights into the health and resilience of marine ecosystems, making it imperative to foster collaborative research that bridges genomics, ecology, and conservation science. This Collection aims to unite scholars and practitioners in marine science, driving forward the collective understanding of how genomics and eDNA can be utilized to address pressing environmental challenges.

The scope of this Collection encompasses a diverse range of topics, including but not limited to:

• The application of eDNA for species detection and monitoring
• The development of genomic tools for assessing genetic diversity and population structure
• The role of marine genomics in informing conservation strategies
• Innovative research exploring the impacts of environmental stressors on marine communities
• Methodological advancements that enhance the efficacy and reliability of eDNA applications

We invite contributions that not only highlight novel findings but also address these key areas of interest. By fostering interdisciplinary collaboration, we aim to enhance the scientific foundation for effective management and conservation of marine resources in an era of rapid environmental change.

This Collection supports and amplifies research related to SDG 14: Life Below Water.

All manuscripts submitted to this journal, including those submitted to collections and special issues, are assessed in line with our editorial policies and the journal’s peer review process.

Marine pollution, particularly from microplastics, has emerged as one of the most pressing environmental challenges of our time. As the global production of plastics continues to rise, the oceans, which cover over 70% of our planet, serve as both a sink and a conveyor of these materials. Microplastics not only threaten marine biodiversity but also pose risks to human health and economic stability. The urgency to address this issue has gained momentum due to growing awareness and public concern over the long-lasting impacts of plastic pollution.

In light of these developments, we have opened a Collection in BMC Marine Science dedicated to the critical examination of marine pollution and microplastics. This Collection aims to bring together a wide range of interdisciplinary research that explores the sources, impacts, and potential solutions.

Topics considered include:

• Environmental fate and transport of microplastics
• Ecological consequences on marine life and ecosystems
• Socio-economic implications of plastic pollution
• Innovative remediation strategies and technologies
• Case studies from diverse marine environments
