We propose using human skin piercings as a model system for studying community assembly after rapid environmental change. Local skin sterilization provides a \u2018clean slate\u2019 within the novel ecological niche created by the piercing. Stochastic assembly processes can dominate skin microbiomes due to the influence of environmental exposure on local dispersal, but deterministic processes might play a greater role within occluded skin piercings if piercing habitats impose strong selection pressures on colonizing species. Here we explore the human ear-piercing microbiome and demonstrate that community assembly is predominantly stochastic but becomes significantly more deterministic with time, producing increasingly diverse and ecologically complex communities. We also observed changes in two dominant and medically relevant antagonists (\n                    <jats:italic>Cutibacterium acnes<\/jats:italic>\n                    and\n                    <jats:italic>Staphylococcus epidermidis<\/jats:italic>\n                    ), consistent with competitive exclusion induced by a transition from sebaceous to moist environments. By exploiting this common yet uniquely human practice, we show that skin piercings are not just culturally significant but also represent ecosystem engineering on the human body. The novel habitats and communities that skin piercings produce may provide general insights into biological responses to environmental disturbances with implications for both ecosystem and human health.\n                  <\/jats:p>","DOI":"10.1098\/rspb.2023.1174","type":"journal-article","created":{"date-parts":[[2023,11,29]],"date-time":"2023-11-29T03:11:33Z","timestamp":1701227493000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Community assembly of the human piercing microbiome"],"prefix":"10.1098","volume":"290","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6779-8879","authenticated-orcid":false,"given":"Charles C.
