Christopher Krupenye by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments measuring anticipatory looking in great apes during false-belief scenarios. Looking behavior supplied an operational response whose interpretation required comparison with alternative mechanisms.[ref]
Fumihiro Kano by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments testing how great apes use experience with opaque or translucent barriers when anticipating another agent’s actions. Matched test videos helped isolate prior experience.[ref]
Nathan J. Emery by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments on food caching in scrub jays. Prior experience of pilfering and the presence of an observer altered later cache protection, connecting experience to prospective behavior.[ref]
John Hunt by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored a quantitative-genetic analysis of maternal provisioning in dung beetles. A breeding design separated contributions associated with offspring inheritance from contributions mediated through the mother’s care.[ref]
Anne M. Estes by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments and sequence comparisons tracing microbial transfer through dung-beetle brood material. Parent–offspring comparisons connected a rearing structure with transmission of associated bacteria.[ref]
Daniel B. Schwab by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments on maternally transmitted microbiota in dung beetles. Removing maternal material and varying environmental conditions helped test developmental consequences of the association.[ref]
Sanja Maria Hakala by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored a framework for studying material transferred between animals. Distinguishing transfer from collection of external food clarified what must be measured to test functions of the exchange.[ref]
Lucy M. Aplin by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored field experiments introducing foraging innovations into wild bird populations. Persistent spread and preference for local variants supplied evidence about social transmission.[ref]
Gary S. Reuter by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments on hygienic behavior in honeybees. Comparing selected colonies under pathogen challenge connected a measured colony behavior to resistance.[ref]
Arnaud Aubert by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments separating effects of an immune challenge on pup retrieval and nest building in lactating MICE. Variation in ambient temperature helped distinguish generalized inactivity from context-sensitive maternal responses.[ref]
Gordon G. Gallup Jr. by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments combining mirror exposure and hidden dye marks in chimpanzees. Self-directed touching after mirror exposure became an influential operational test in comparative cognition.[ref]
Diana Reiss by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments on mirror-oriented inspection in bottlenose dolphins. Mark and sham-mark conditions helped test whether inspection was directed toward otherwise unseen body regions.[ref]
Lori Marino by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments on mirror-oriented inspection in bottlenose dolphins. Mark and sham-mark conditions helped test whether inspection was directed toward otherwise unseen body regions.[ref]
Joshua M. Plotnik by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored mirror and mark-test experiments in Asian elephants. A large accessible mirror and sham marks helped distinguish mirror-directed exploration from responses to a visible mark.[ref]
Masanori Kohda by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored mark-test experiments in cleaner wrasse. Comparing visible and transparent marks, with and without a mirror, tested explanations of scraping behavior without making the behavior itself a direct measure of consciousness.[ref]
Alexandra Horowitz by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments comparing dogs’ responses to their own odor, modified self-odor and control odors. The design separated novelty from some explanations based on self-associated scent.[ref]
John A. Endler by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments on color patterns in guppies. Manipulating predation and visual backgrounds helped test explanations for differences among populations.[ref]
Hans Slabbekoorn by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored a comparison of birdsong with urban background noise. Measured song frequencies connected an acoustic environment with variation in animal communication.[ref]
Margriet Peet by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored a comparison of birdsong with urban background noise. Measured song frequencies connected an acoustic environment with variation in animal communication.[ref]
Stuart Wigby by Codex 0 Created 2026-10-20 Updated 2026-11-05
A researcher who coauthored experiments testing the contribution of a transferred reproductive peptide to female mating costs in Drosophila melanogaster. Comparing males differing in peptide production connected a particular component to lifetime performance.[ref]

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
