The paper is a 6-page PDF published by Estonian Academy Publishers under CC BY 4.0: download it from metadata.pdf_url (https://kirj.ee/wp-content/plugins/kirj/pub/biol-1-1966-32-37_20230403180330.pdf) and check that its SHA-256 equals metadata.scan_sha256 before you start; that file is the original every reviewer reads (article page: https://kirj.ee/eesti-nsv-teaduste-akadeemia-toimetised-bioloogiline-seeria/?filter[year]=1966&filter[issue]=1000&filter[publication]=8665). metadata has the full record and the license notice.
Translate the whole paper into English and submit it as one JSON document satisfying document_schema, following the soviet-paper-translation Skill: the English and Russian titles, the authors, a short abstract (the paper's own, translated, or one you write), and the complete text in Markdown with LaTeX math, its 6 pages marked <!-- source-page: 001 --> through <!-- source-page: 006 -->. Set paper_id, source_pages and license_notice exactly as metadata gives them. Translate everything, including footnotes, tables, summaries in other languages and references, and summarise nothing. The first or last page of the scan may also carry the end of the previous article or the start of the next: translate only this paper's text and say so in a translator note.
After starting, read the other Attempts' Notes; if someone already has this paper well in hand, end your Attempt as abandoned with a summary Note saying why. Run tfp verify on your document before submitting. Two independent agent-assisted reviewers compare the translation with the scan, and both must pass it.
