About this Research Topic

Background

Solving foraging problems requires animals to make adaptive decisions that optimize costs and benefits, and is thought to have been an important driver in the evolution of enhanced cognitive skills in primates. Interspecies comparisons across the primate order suggest variation in several key cognitive processes mobilized for foraging, but which socio-ecological factors drive these differences, and how they affect individual fitness are fundamental unanswered questions. Primates can, for example, remember the location and quality of resources in their environment, and use topological representations of space to navigate when foraging. However, there are still gaps in our knowledge regarding the role and neural correlates of more sophisticated cognitive mechanisms such as temporal memory, large-scale spatial planning, and information sharing. Indeed, many foraging behaviors likely require the integration of multiple cognitive abilities spanning both the ecological and social domains. A more complete understanding of the diversity in foraging strategies and cognitive abilities in different socio-ecological contexts is crucial to elucidating cognitive evolution in primates past and present.

This interdisciplinary Research Topic aims to bring together current advances in the fields of socio-ecology, neuroethology, movement ecology, energetics, and primate foraging strategies in relation to cognition. The focus will be on the mechanisms that underlie foraging decisions at the individual and collective levels. We will place particular emphasis on the cognitive abilities needed to support complex foraging strategies in challenging and rapidly changing socio-ecological environments, and will integrate these findings with studies from laboratory and captive environments. The discussion arising from this interdisciplinary exchange should foster the debate on the evolutionary origins of foraging cognition within a wider scientific community of behavioral ecologists, comparative psychologists, neuroscientists, paleoanthropologists, and evolutionary biologists. Contributions about both modern primates and extinct hominins, and from laboratory settings and fieldwork, as well as evolutionary perspectives, are encouraged. The resulting synthesis will have important implications not only for a deeper understanding of the evolution of primate cognition but also for captive primate welfare and wild primate conservation.

We welcome manuscripts focused on living and/or extinct primates and on the following subjects:
• Foraging cognition and its neural correlates
• Spatial foraging decisions
• Time-sensitive foraging decisions
• Ecological complexity of extant and extinct primate environments
• Landscape use
• Landscape energetics
• Group foraging movements: leadership and collective decisions
• Social information transfer in foraging contexts
• Behavioral and physiological adaptations to anthropogenic habitats
• Interactions of microbiota on metabolism and foraging cognition
• Physical cognition (e.g. tool use, food processing) in the context of foraging
• Life history and foraging strategies
• Links between foraging strategies and fitness outcomes
• Self-medication
• Language and spatial coding of the environment

We call for original papers, reviews, and other forms of scientific communication with particular attention to current advances in the field of foraging cognition.

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.
