Using a two-year open-top chamber (OTC) warming experiment, we investigated the responses of community composition, abundance, alpha diversity, and beta diversity in aboveground vegetation and the soil seed bank under experimental warming. Experimental warming significantly increased aboveground biomass to 1.73 times that of the CK treatment under the high-OTC treatment, while reducing species richness and the Shannon diversity index by 29.07% and 22.64%, respectively. Warming also promoted species turnover, increasing the beta diversity of aboveground vegetation by 24% and 37% under the low- and high-OTC treatments, respectively. In contrast, the soil seed bank mainly exhibited an increase in seed density, reaching 2.47 times that of the CK treatment under the high-OTC treatment, whereas species richness increased only slightly, and beta diversity remained relatively stable despite a significant, but comparatively smaller, shift in community composition. Overall, aboveground vegetation exhibited stronger responses to short-term warming, whereas the soil seed bank showed relatively stable diversity and community characteristics under the same warming treatments. These contrasting response patterns suggest that the greater stability of the soil seed bank may provide an important source of propagules for future vegetation regeneration and community restoration. Our findings reveal contrasting aboveground-belowground responses to warming and provide new insights into predicting the responses of alpine meadow plant communities to future climate warming.<\/jats:p>","DOI":"10.3390\/plants15162435","type":"journal-article","created":{"date-parts":[[2026,8,11]],"date-time":"2026-08-11T08:09:36Z","timestamp":1786435776000},"page":"2435","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Contrasting \u03b1- and \u03b2-Diversity Responses of Aboveground Vegetation and Soil Seed Banks to Experimental Warming over Two Consecutive Growing Seasons"],"prefix":"10.3390","volume":"15","author":[{"given":"Yuning","family":"Zhang","sequence":"first","affiliation":[{"name":"Pratacultural College, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shanheng","family":"Shi","sequence":"additional","affiliation":[{"name":"College of Agronomy and Biotechnology, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuankai","family":"Zhuang","sequence":"additional","affiliation":[{"name":"Pratacultural College, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziyan","family":"Zhou","sequence":"additional","affiliation":[{"name":"Pratacultural College, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoni","family":"Liu","sequence":"additional","affiliation":[{"name":"Pratacultural College, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yafei","family":"Shi","sequence":"additional","affiliation":[{"name":"Pratacultural College, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1038\/nature01286","article-title":"A globally coherent fingerprint of climate change impacts across natural systems","volume":"421","author":"Parmesan","year":"2003","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1770","DOI":"10.1126\/science.287.5459.1770","article-title":"Global biodiversity scenarios for the year 2100","volume":"287","author":"Sala","year":"2000","journal-title":"Science"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"141344","DOI":"10.1016\/j.scitotenv.2020.141344","article-title":"Alpine vegetation in the context of climate change: A global review of past research and future directions","volume":"748","author":"Verrall","year":"2020","journal-title":"Sci.
