Along elevational gradients, abiotic conditions influence community assembly by filtering species based on their functional strategies, which themselves may be phylogenetically structured. However, it remains challenging to identify which abiotic factors and functional traits are most relevant for gradient-wide assembly, particularly when potential drivers covary.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n We intensively sampled the composition and leaf traits of woody plant communities across a steep elevational gradient on Mt. Washington (New Hampshire, USA). Topo-edaphic and climatic conditions were measured to mechanistically link environmental with compositional variation. Gradient-wide trait variation was assessed using nonmetric multidimensional scaling while elevational patterns in taxonomic, functional, and phylogenetic alpha and beta diversity were quantified. Environmental drivers of trait-mediated community assembly were then identified with Bayesian generalized mixed effects regressions models.<\/jats:p>\n <\/jats:sec>\n \n Key Results<\/jats:title>\n Three plant community zones were identified with hierarchical clustering: broad-leaved deciduous forest, needle-leaved evergreen forest, and alpine tundra. Plants in alpine communities often had higher leaf nitrogen and \u03b413C, whereas leaf area and \u03b415N peaked in broad-leaved deciduous forests. Alpha diversity metrics tended to increase with soil nitrogen (typically at lower elevations) and on exposed topography (typically at higher elevations), while taxonomic and phylogenetic beta diversity peaked in alpine communities. Soil clay content emerged as a driver of community composition across all communities, filtering woody plants based on water-use efficiency (measured with leaf \u03b413C). Gradient-wide compositional turnover was not phylogenetically structured, and models with topo-edaphic variables outperformed those with elevation alone.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Trait-based assembly processes likely predominate across Mt. Washington\u2019s woody plant communities, with local topo-edaphic factors filtering species based on their functional strategies. In particular, functional water availability may structure plant communities based on individual- and species- water use efficiency, while diversity patterns may mirror gradient-wide variation in fine-scale environmental heterogeneity.<\/jats:p>\n <\/jats:sec>","DOI":"10.1093\/aob\/mcag324","type":"journal-article","created":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T11:39:56Z","timestamp":1791286796000},"source":"Crossref","is-referenced-by-count":0,"title":["Taxonomic, functional, and phylogenetic structure of Mt.
