While epigenetic mechanisms can generate phenotypic plasticity, their role in mediating adaptive life\u2010history transitions in the wild is largely unknown. Here, we show that in adult Namibian cheetahs (\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Acinonyx jubatus jubatus<\/jats:italic>\n                    <\/jats:styled-content>\n                    ), a species with remarkably low genetic diversity, the transition from a floater to a male holding a territory is associated with widespread DNA methylation changes, with a predominance of hypermethylation in territorial males. Using paired blood samples collected from the same individuals before and after becoming territorial, we identified differentially methylated genes which function in pathways related to anatomical and head development, brain development and neurodevelopment, cAMP biosynthesis and ion channel transport, consistent with the observed phenotypic shifts in morphology, spatial movement and aggressive behaviour. These findings suggest that DNA methylation mediates this life\u2010history transition at the molecular level. More broadly, they provide rare evidence that epigenetic regulation is relevant in phenotypic diversity within species with low genetic diversity, potentially supporting adaptive potential at the population level.\n                  <\/jats:p>","DOI":"10.1111\/mec.70527","type":"journal-article","created":{"date-parts":[[2026,9,7]],"date-time":"2026-09-07T08:02:36Z","timestamp":1788768156000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Epigenetic Changes Associated With a Phenotypic Transition in Namibian Cheetahs"],"prefix":"10.1111","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9218-1571","authenticated-orcid":false,"given":"Colin","family":"Vullioud","sequence":"first","affiliation":[{"name":"Department of Evolutionary Genetics Leibniz\u2010Institute for Zoo and Wildlife Research (IZW)  Berlin Germany"},{"name":"Chair of Modelling of Social\u2010Ecological Systems University of Freiburg  Freiburg im Breisgau Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana","family":"Geweiler","sequence":"additional","affiliation":[{"name":"Department of Evolutionary Genetics Leibniz\u2010Institute for Zoo and Wildlife Research (IZW)  Berlin Germany"},{"name":"University of Potsdam  Potsdam Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3490-1515","authenticated-orcid":false,"given":"Joerg","family":"Melzheimer","sequence":"additional","affiliation":[{"name":"Department of Evolutionary Ecology Leibniz\u2010Institute for Zoo and Wildlife Research (IZW)  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8934-009X","authenticated-orcid":false,"given":"Sonja","family":"Heinrich","sequence":"additional","affiliation":[{"name":"Department of Evolutionary Ecology Leibniz\u2010Institute for Zoo and Wildlife Research (IZW)  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0593-5820","authenticated-orcid":false,"given":"J\u00f6rns","family":"Fickel","sequence":"additional","affiliation":[{"name":"Department of Evolutionary Genetics Leibniz\u2010Institute for Zoo and Wildlife Research (IZW)  Berlin Germany"},{"name":"University of Potsdam  Potsdam Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0414-2298","authenticated-orcid":false,"given":"Bettina","family":"Wachter","sequence":"additional","affiliation":[{"name":"Department of Evolutionary Ecology Leibniz\u2010Institute for Zoo and Wildlife Research (IZW)  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6944-1854","authenticated-orcid":false,"given":"Alexandra","family":"Weyrich","sequence":"additional","affiliation":[{"name":"Department of Evolutionary Genetics Leibniz\u2010Institute for Zoo and Wildlife Research (IZW)  Berlin Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,7]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/17501911.2025.2464529"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/hmg\/ddi140"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010022\u201009336\u20100"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1101\/gad.947102"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.95.1.241"},{"key":"e_1_2_13_7_1","doi-asserted-by":"publisher","DOI":"10.3389\/fgene.2022.960958"},{"key":"e_1_2_13_8_1","doi-asserted-by":"publisher","DOI":"10.1023\/A:1010933404324"},{"key":"e_1_2_13_9_1","volume-title":"Cheetahs of the Serengeti Plains: Group Living in an Asocial Species","author":"Caro T.
