About this Research Topic

Background

Plankton, primarily composed of microorganisms, dominate the biomass in marine and freshwater ecosystems and play a critical role in driving global carbon and nutrient cycling. Notably, phytoplankton is responsible for roughly half of the Earth’s photosynthetic carbon fixation. Heterotrophic plankton, which primarily feed on phytoplankton-derived resources, are essential for nutrient remineralization and long-term carbon sequestration. Environmental fluctuations that occur daily, seasonally, and over multi-year cycles are major factors influencing the growth of both autotrophic and heterotrophic plankton. Existing species have evolved various metabolic strategies to cope with periodic changes in light, temperature, and other environmental factors, although the detailed mechanisms behind these adaptations remain largely unclear. Furthermore, in an integrated community, interactions among different types of plankton contribute to the complex dynamics of ecosystems, making these relationships important to study but also challenging to understand.

Through multidisciplinary research involving experts in microbiology, ecology, and aquatic sciences, we aim to improve our understanding of how different groups of microbial plankton respond to both abiotic and biotic environmental changes across diel, seasonal, and multi-year cycles. We will explore the ecological and biogeochemical implications of these responses. We also welcome research conducted in the laboratory, focusing on metabolic mechanisms in model organisms, and field and model studies that examine integrative community patterns in aquatic ecosystems. By combining these approaches, we aim to develop a comprehensive understanding of plankton dynamics in aquatic environments across scales. We anticipate that this knowledge will lead to less biased evaluation of the functionality of aquatic ecosystems and improve our understanding of carbon sequestration strategies, ultimately aiding in efforts to mitigate global climate change.

We welcome Original Research, Reviews and Opinions on the following subjects, but not limited to:

• Field or Microcosm Observations: Investigations into plankton communities that uncover diel, seasonal, or multi-year patterns, enhancing our understanding of metabolic responses and inter-species interactions amid changing environments;

• Empirical Ecophysiological Research: Studies focusing on how specific plankton taxa adjust their metabolic processes to cope with stresses, ensure survival, and achieve optimal growth in fluctuating environmental conditions;

• Characterizations and Predictions of Ecosystem Resilience: Research characterizing and predicting plankton dynamics and their responses to changing environmental factors, relevant to both current and future oceanic conditions.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
