Flyer advertising special collection of stories for Frontiers for Young Minds. We invite expressions of interest for a curated collection of short articles on animal behavior to be published in Frontiers for Young Minds, an open-access journal for readers ages 8–15.
This international collection, developed in collaboration with the Animal Behavior Society, will introduce young readers to how scientists explain behavior using Tinbergen’s four questions. Each article will be co-authored by a researcher and an undergraduate, with an emphasis on clear, engaging communication.
Articles will be ~1,500 words and designed for a broad student and classroom audience. Contributors will work with an undergraduate co-author and participate in iterative editorial development prior to submission.
We anticipate selecting approximately 10–12 articles, depending on the strength and diversity of submissions.

With data from >100k special issues, we set out to tackle this problem.

Guest editors publishing in their own issues is a form of "endogeny". In this study, we define special issues with extreme endogeny as Published In Support of Self (PISS).

So, how much of this literature is PISS?

Have you considered whether animals differ in their perception of density?

We explored how differences in our senses, interpretation and past experiences shapes density perception, causing behavioral differences and affecting fitness outcomes. 🧪
