About this Research Topic

Background

Understanding complex interactions between abiotic and biotic factors and their impact on the structure of forest communities across space and time is a major goal in ecological research. Studies of past ecosystems can provide insights into current and future forest dynamics. However, disentangling the relationships between biotic and abiotic factors in the fossil record has historically been challenging. Paleoecological and dendroecological approaches are among the main tools used to reconstruct past forest dynamics, disturbance regimes and biotic and abiotic interactions.

Forests are complex systems where many factors and processes interact simultaneously at multiple spatial scales. However, to date, paleoecological research has largely focused on climate change and wildfire, while other natural disturbances (e.g. insect outbreaks, hurricanes, etc.) and abiotic-biotic interactions have been neglected, even if they are known to be major drivers of forest structure and dynamics. The main reason for this relative lack of paleoecological research to account for the abiotic-biotic interactions has been the absence of reliable proxies. However, several new developments have shown promise, potentially opening the way to new interpretations of the proxy record, and advances in the understanding of long-term development of forest ecosystems. It is thus essential to review methodological advances and interdisciplinary approaches to tackle these questions in innovative ways across taxonomic groups, forest ecosystems and disturbance types.

We are living a crucial moment in ecology, facing climate change. Paleoecology and dendroecology are essential tools looking for solutions to current challenges in forest sciences. In many regions of the world, they greatly surpass the time span of the documentary or remote sensing records, and thus provide the temporal depth required to assess ecological change over long time scales. This Research Topic aims at filling knowledge gaps regarding both the understanding of forest ecosystem structure and dynamics and innovative methodologies in paleoecology and dendroecology, highlighting the implications for sustainable management of forest resources under climate change.

This Research Topic will embrace multi-scalar and multi-disciplinary approaches, from stand to landscape and from the Quaternary to the Anthropocene. In this Research Topic, we aim to publish a series of articles that will cover a diversity of approaches, including new paleoindicators and multiproxy studies, drawing on examples from forest ecosystems around the world. In particular, we welcome submissions on the following topics:
• Reconstruction of natural disturbance regimes, e.g. wildfire, insect outbreaks, hurricanes, etc.
• Disturbance interactions in forest ecosystems,
• Reconstruction of forest dynamics through time,
• New methods and proxies in paleoecology and dendroecology,
• Description of drivers of natural disturbances in forest ecosystems,
• Biotic and abiotic interactions in past forest ecosystems, e.g. seed dispersal, herbivory

We welcome empirical studies, original research, meta-analyses and novel methods from around the World, as well as Reviews, Perspectives and Opinions to consolidate this topic and provide trends and challenges in paleoecology, as well as future research priorities.

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 it falls 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?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
