However, whether PDSR is temporally unstable during community succession, and the mechanisms underlying such instability, remain poorly understood. In this study, we used a fermentation microbial community as a model and established a closed microcosm system spanning a 10\u20131000 mL volume gradient. By continuous sampling over 0\u201360 days and 16S rRNA high-throughput sequencing, we characterized the dynamic changes in PDSR throughout succession. The results showed that PDSR underwent stage-specific shifts during community succession: it was significantly positive in the early stage, weakened or became non-significant in the middle stage, and turned negative or remained non-significant in the late stage. The early positive PDSR was mainly attributable to the greater retention of rare lineages in larger-volume habitats, whereas in the late stage, phylogenetic diversity increased in smaller-volume habitats, suggesting a positive role in the resuscitation of potentially dormant lineages. Phylogenetic beta-diversity analysis further showed that lineage turnover rate increased over time, with significant divergence among samples in the later stage. In addition, pH decreased significantly over succession and, through interactions with time and volume, exerted a marked influence on community phylogenetic structure. This study reveals the temporal dynamism of biodiversity spatial patterns and confirms that PDSR shifts non-steadily across successional stages, providing new insights into the organization of microbial diversity across multiple scales.<\/jats:p>","DOI":"10.3390\/microorganisms14071539","type":"journal-article","created":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T10:12:53Z","timestamp":1784023973000},"page":"1539","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Temporal Dependence of the Phylogenetic Diversity\u2013Habitat Size Relationship: Evidence from a Closed Fermentation System"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4757-0217","authenticated-orcid":false,"given":"Yiting","family":"Cheng","sequence":"first","affiliation":[{"name":"Institute of Eastern-Himalaya Biodiversity Research, Dali University, Dali 671003, China"},{"name":"Center for Interdisciplinary Sciences, Dali University, Dali 671003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4918-7550","authenticated-orcid":false,"given":"Wei","family":"Deng","sequence":"additional","affiliation":[{"name":"Institute of Eastern-Himalaya Biodiversity Research, Dali University, Dali 671003, China"},{"name":"Provincial Innovation Team for Biodiversity Conservation and Utilization in the Three Parallel Rivers Region, Dali University, Dali 671003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kun","family":"Tan","sequence":"additional","affiliation":[{"name":"Institute of Eastern-Himalaya Biodiversity Research, Dali University, Dali 671003, China"},{"name":"Center for Interdisciplinary Sciences, Dali University, Dali 671003, China"},{"name":"Provincial Innovation Team for Biodiversity Conservation and Utilization in the Three Parallel Rivers Region, Dali University, Dali 671003, China"},{"name":"Collaborative Innovation Center for Biodiversity and Conservation in the Three Parallel Rivers Region of China, Dali 671003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4951-7524","authenticated-orcid":false,"given":"Wen","family":"Xiao","sequence":"additional","affiliation":[{"name":"Institute of Eastern-Himalaya Biodiversity Research, Dali University, Dali 671003, China"},{"name":"Center for Interdisciplinary Sciences, Dali University, Dali 671003, China"},{"name":"Provincial Innovation Team for Biodiversity Conservation and Utilization in the Three Parallel Rivers Region, Dali University, Dali 671003, China"},{"name":"Collaborative Innovation Center for Biodiversity and Conservation in the Three Parallel Rivers Region of China, Dali 671003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"95","DOI":"10.2307\/2255763","article-title":"Species and area","volume":"9","author":"Arrhenius","year":"1921","journal-title":"J.
