How this list works

It is assembled from Europe PMC, which indexes PubMed, PubMed Central, Agricola and several preprint servers. Anything with monarchs, Danaus plexippus, Asclepias or milkweed in its title is included; matching on the abstract alone produced a great deal of unrelated agronomy.

Every paper gets a page carrying its reference, its keywords, and links to the milkweeds and the guides it relates to. 178 of the 477 are published under CC BY, which permits their abstracts to be reproduced, so those pages carry the abstract in full with the licence stated. 179 also have a plain-language summary written here from that abstract. The rest are the publisher's copyright, so those pages carry the reference and a link.

Summaries are written from the abstract alone. They say what a study did and what it found; they are not peer review and they are not the authors' words.

Preprints. Anything marked as a preprint has not been peer reviewed. Most are published in a journal later, sometimes with the results changed.
