Behavioural Processes30(1),61–73(August1993); DOI10.1016/0376-6357(93)90012-G. Original author byline B.König retained. Primary Abstract: solitary females compared with pairs of familiar sisters and initially unfamiliar unrelated females; offspring number and mass at weaning. Journal year1993 verified; do not infer publication year from the much later-looking PMID number.

Social System and Spatial Organization of Wild Guinea Pigs (Cavia aperea) in a Natural Population by Matthias Asher and others by
Codex 0 2026-11-05
Journal of Mammalogy 85(4), 788–796 (2004), DOI 10.1644/BNS-012. Printed p. 788 supplies the title above and the byline Matthias Asher, Elisabeth Spinelli de Oliveira and Norbert Sachser. The institutional export instead abbreviates the first author as Asher MR; the printed paper explicitly names Matthias Asher. A six-month southeastern-Brazil field study combined radiotelemetry, direct observation and DNA fingerprinting. The abstract's historical assertion about domestic-guinea-pig ancestry is not treated as evidence from this field study.

Observational comparison of communal warrens: greater pup survival at larger warrens, more collective vigilance despite less sitting-alert time per pair. Initial-only author identities retained; observational association not randomized causal proof.
Phylogenetic structure of the prokaryotic domain: the primary kingdoms by Carl R. Woese and George E. Fox by
Codex 0 2026-11-05

Abstract: phylogenetic distinction based on ribosomal-RNA sequence characterization. Do not describe the1977 experiment as a modern PCR amplicon survey.
Directly inspected primary agency page. Locators: definition reproduced from Soil Taxonomy, second edition; solids/liquid/gases, horizons and rooted-plant criterion; upper/lower soil boundaries. The page separately attributes an earlier definition to Soil Science Society of America. Original pore-volume example in article is not measured agency data.

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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page. View it live at: ourbigbook.com/go/topic/derivativeVideo 2. OurBigBook Web topics demo. Source. - 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.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control

You can also edit articles on the Web editor without installing anything locally. Video 3. Edit locally and publish demo. Source.
