Abstract Questions Analysing how multiple facets of biodiversity vary across space and time can help to predict the vulnerability mountaintop floras future environmental changes. Here we addressed following questions: (a) Are elevational patterns plant diversity consistent taxonomy, function phylogeny? (b) How have taxonomic, functional phylogenetic dimensions communities changed over past two decades? (c) Is magnitude these temporal trends dependent on elevation? Location Dovrefjell, central Norway. Methods The floristic composition four mountaintops, spread an gradient from tree line uppermost margins vascular life, was surveyed every 7 years between 2001 2022. Six metrics richness differentiation were calculated for each survey. Using data, assessed varied (across gradient) (between surveys).

Understanding how and why assemblage dissimilarity changes along spatial gradient is a great challenge in ecology, because answers to these questions depend on the analytical types, dimensions, components of beta diversity we concerned. To obtain comprehensive understanding its implications for biodiversity conservation Himalayas, explored elevational patterns determinants turnover nestedness pairwise multiple types taxonomic phylogenetic dimensions simultaneously. Patterns their different were calculated based 96 sampling quadrats an 1800−5400 m gradient. We examined whether differed from random expectations using null models. Furthermore, used forest methods quantify role environmental variables representing climate, topography, human disturbance determining patterns. found that component, regardless shown hump-shaped Both remarkably lower than counterpart. These significantly less expectation mostly associated with climate variables. In summary, our results suggested seed plants was originate replacement closely related species determined by climate-driven filtering. Accordingly, efforts should better cover elevations maximalize conservation, rather only focus highest richness. Our study demonstrated comparisons could be conductive consensus origin mechanism dissimilarity.
