The weighted median of interspecies distances in traits (a robust alternative to Rao's quadratic entropy) was used to determine functional diversity.

However, the evidence for sharp decreases in diversity has mainly been found in marine and freshwater systems and for animals (Bellwood et al., &lt;span&gt;2004&lt;/span&gt;; Wilson et al., &lt;span&gt;2005&lt;/span&gt;; Reid et al., &lt;span&gt;2019&lt;/span&gt;; Albert et al., &lt;span&gt;2021&lt;/span&gt;), but less so in terrestrial systems and for plant species which show a higher resistance to climate change than originally predicted (Thuiller et al., &lt;span&gt;2005&lt;/span&gt;; Bertrand et al., &lt;span&gt;2011&lt;/span&gt;; Cheaib et al., &lt;span&gt;2012&lt;/span&gt;; Lenoir, &lt;span&gt;2022&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;Alpine plant communities are considered the most sensitive terrestrial system for biodiversity changes because of the steepness of ecological gradients and the isolation of most alpine summits (Körner, &lt;span&gt;2003&lt;/span&gt;; Anthelme &amp; Lavergne, &lt;span&gt;2018&lt;/span&gt;). However, changes in species richness are highly dependent on the environmental context in terms of elevation, regional climates, soil types, snow cover duration and human pressure (Kammer et al., &lt;span&gt;2007&lt;/span&gt;; Scherrer &amp; Körner, &lt;span&gt;2011&lt;/span&gt;; Rumpf et al., &lt;span&gt;2018&lt;/span&gt;; Nicklas et al., &lt;span&gt;2021&lt;/span&gt;). Pioneer resurvey studies have shown that species richness has increased at the high alpine and nival belts, probably due to climate warming (Grabherr et al., &lt;span&gt;1994&lt;/span&gt;; Gottfried et al., &lt;span&gt;2012&lt;/span&gt;; Pauli et al., &lt;span&gt;2012&lt;/span&gt;; Steinbauer et al., &lt;span&gt;2018&lt;/span&gt;), but the few studies conducted at the subalpine belt have rather observed decreases in species richness probably due to increasing competition with climate warming (Vittoz et al., &lt;span&gt;2009&lt;/span&gt;; Alexander et al., &lt;span&gt;2015&lt;/span&gt;; Nicklas et al., &lt;span&gt;2021&lt;/span&gt;; Michalet et al., &lt;span&gt;2024&lt;/span&gt;). Different regional climates may also trigger different community responses because competition is more likely to increase with warming in wet climates, whereas facilitation is expected to increase with increasing drought in drier climates, with opposite consequences for species richness (Choler et al., &lt;span&gt;2001&lt;/span&gt;; Callaway et al., &lt;span&gt;2002&lt;/span&gt;; Michalet et al., &lt;span&gt;2014&lt;/span&gt;). For example, comparing changes in alpine vegetation between the temperate climate of the Central Alps, the submediterranean climate of the Apennines and the drier Mediterranean climate of Crete, Steinbauer et al. (&lt;span&gt;2022&lt;/span&gt;) found a thermophilization of the vegetation in the two northern wet mountains only, with a decline of cold-adapted cushion plants in the Alps. In addition, different mountain regions can further show dissimilar species pools, which is well recognized as a source of contingencies in community responses (Lessard et al., &lt;span&gt;2012&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;Changes in species richness are also highly dependent on snow cover duration varying across space and time, that is, along mesotopography gradients and with climate change, respectivel","PeriodicalId":49965,"journal":{"name":"Journal of Vegetation Science","volume":"35 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jvs.13254","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140556394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
