When reared together in bispecific groups, workers of both\r\nspecies possess each other's hydrocarbons in both locations. The present study investigated two\r\nalternative mechanisms by which a mixed \"odour\" in artificial groups of Formica selysi/Manica\r\nrubida can be created. Using [1-14C] sodium acetate as a precursor, de novo biosynthesis of hydrocarbons was demonstrated for both species whether reared in homospecific or mixed-species\r\ngroups. The newly synthesized hydrocarbons occurred on the epicuticle, internally, and in particularly large amounts in the PPG. As expected from their PPG and epicuticular hydrocarbons\r\ncomposition, workers E selysi synthesized alkanes and alkenes in comparable amounts irrespective\r\nof their rearing scheme. Likewise, M. rubida reared in bispecific groups synthesized mostly\r\nalkanes with only negligible amounts of alkenes, according to a ratio characteristic to M. rubida\r\nworkers from homospecific groups and not to E selysi workers. During dyadic encounters, a\r\ntransfer of labeled hydrocarbons between nestmates (conspecific in homospecific groups and\r\nallospecific in mixed groups) was observed. These results suggest that the formation of the mixed\r\nhydrocarbon profile in artificial groups of ants is the result of a transfer of these chemicals between\r\nnestmates rather than de novo biosynthesis of the allospecific hydrocarbons. Behaviours like\r\ntrophallaxis, grooming and body contact that occurred during the encounters mediated such a\r\ntransfer.","url_abs":"https://link.springer.com/article/10.1007/BF01240421","url_pdf":"https://d1wqtxts1xzle7.cloudfront.net/97711700/bf0124042120230124-1-s872ta-libre.pdf?1674523051=&response-content-disposition=inline%3B+filename%3DCongruency_of_hydrocarbon_patterns_in_he.pdf&Expires=1722076892&Signature=HiPMhuPpKny~N1Aubc9fKPsH5ALlGX9-zzsPP6yz9PxnsNewGCOdHa5RQy9WTmXCp2couZK4bIf0yiet7VKYra3bdE6j0EF8NVURCBuBrsOVJWp~FR6DfeX2r2Yz-1Ho2uCbjeRslqX59Z2DHpqF04Zfp33~jM~KyEXyfV2nr6L~HBpkenHSkXJ~sIV6LoYGJhPOSXwREy3oGj5TjCpqeVpPd8Z2IYbs48S12vnTWlFmIy1~te0viJcnv3k5aMEftWYQKl-S-ZbU4yb-j-C~oqh~pSNyQ6EzIYnTCBPFS3k9o~ruOCCkl7BukUCkVhTqUeUIA~JSxDBOLEYuyVCljA__&Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"congruency-of-hydrocarbon-patterns-in","repo_url":"https://github.com/2024-MindSpore-1/Code2/tree/main/model-1/cpmant","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"mindspore","reach":null},{"paper_slug":"congruency-of-hydrocarbon-patterns-in","repo_url":"https://github.com/MindCode-4/code-3/tree/main/cpmant","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"mindspore","reach":null},{"paper_slug":"congruency-of-hydrocarbon-patterns-in","repo_url":"https://github.com/pwc-1/Paper-8/tree/main/cpmant","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"mindspore","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
