However, relevant studies have focused predominantly on angiosperms, and the whole-plant trait coordination structure in ancient fern lineages remains unclear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this study, we simultaneously measured biomass allocation fractions, stoichiometric traits (C, N, P, C:N, C:P, N:P) and morphological traits (SLA, LDMC, etc.) in both leaves and roots of seven co-occurring subtropical forest fern species. Using correlation analyses at the individual and species levels, partial least squares path modeling (PLS-PM) and Mantel tests, we examined the allocation\u2013stoichiometry\u2013morphology cascade pathway and cross-organ coordination patterns.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key Results<\/jats:title>\n                    <jats:p>The results showed that: (1) a significant pathway exists in leaves, with allocation influencing morphology via stoichiometry\u2014higher leaf biomass investment was associated with lower N and P concentrations and more conservative leaf morphology, consistent with the leaf economics spectrum; (2) in roots, the positive direct effect of allocation on morphology was offset by a negative indirect effect mediated by reduced nutrient concentrations, resulting in a near-zero total effect, supporting the multidimensionality of the root economics space; (3) cross-organ coordination was relatively strong for stoichiometric traits (Mantel\u2019s r = 0.69) but weak for morphological traits (r = 0.31), indicating dimension-dependent coordination; (4) the above trait relationships were significant at the individual level but mostly disappeared at the species level, suggesting that intraspecific variation may contribute importantly to community functional patterns.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study reveals a cascade structure of whole-plant trait organization in ferns, provides new evidence for the applicability of the leaf economics spectrum in ancient vascular plants, and highlights the need for experimental validation with a broader sampling scope to establish causality.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/aob\/mcag315","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T11:46:06Z","timestamp":1790682366000},"source":"Crossref","is-referenced-by-count":0,"title":["Biomass allocation and leaf\u2013root trait coordination of dominant ferns in a subtropical forest"],"prefix":"10.1093","author":[{"given":"Chumin","family":"Huang","sequence":"first","affiliation":[{"name":"School of Ecological Engineering, Guizhou University of Engineering Science , Bijie City 551700 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shun","family":"Zou","sequence":"additional","affiliation":[{"name":"School of Ecological Engineering, Guizhou University of Engineering Science , Bijie City 551700 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolong","family":"Bai","sequence":"additional","affiliation":[{"name":"School of Ecological Engineering, Guizhou University of Engineering Science , Bijie City 551700 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wangjun","family":"Li","sequence":"additional","affiliation":[{"name":"School of Ecological Engineering, Guizhou University of Engineering Science , Bijie City 551700 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"He","sequence":"additional","affiliation":[{"name":"School of Ecological Engineering, Guizhou University of Engineering Science , Bijie City 551700 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,9,30]]},"container-title":["Annals of Botany"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/aob\/advance-article-pdf\/doi\/10.1093\/aob\/mcag315\/71499274\/mcag315.pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/aob\/advance-article-pdf\/doi\/10.1093\/aob\/mcag315\/71499274\/mcag315.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,30]],"date-time":"2026-09-30T08:13:37Z","timestamp":1790756017000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/aob\/advance-article\/doi\/10.1093\/aob\/mcag315\/8851438"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,30]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1093\/aob\/mcag315","relation":{},"ISSN":["1095-8290"],"issn-type":[{"value":"1095-8290","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,30]]},"article-number":"mcag315"}}
