Along with climate change, this trend adversely affects several aspects of biodiversity, causing the loss of genetic diversity (Des Roches et al., <span>2021</span>; Laikre et al., <span>2020</span>; Schlaepfer et al., <span>2018</span>), species richness (Tilman et al., <span>2017</span>), and related ecosystem services (Cardinale et al., <span>2012</span>). However, not all species respond in the same way to these factors, with some species being more vulnerable to the mentioned threats than the others. In plants, the response of certain species may depend on their life history, functional traits, phenotypic plasticity, and biogeographic origin (De Kort et al., <span>2021</span>; Hamrick & Godt, <span>1996</span>). In addition, the effects of fragmentation and climate change on plant mutualistic partners, such as pollinators (Bennett et al., <span>2020</span>; Rodger et al., <span>2021</span>), seed dispersers (Donoso et al., <span>2022</span>) or mycorrhizal fungi (Kiesewetter et al., <span>2023</span>; Outhwaite et al., <span>2022</span>; Senapathi et al., <span>2017</span>), may affect the relative vulnerability of plant species to the factors of global change. Outcrossing, animal-pollinated plants may be more susceptible to climate change and habitat fragmentation than clonally reproducing, selfing, or anemophilous plants due to potential negative impacts of habitat loss and climate change on pollinators (Aguilar et al., <span>2008</span>; Bennett et al., <span>2020</span>; Rodger et al., <span>2021</span>). Furthermore, reduced pollinator abundance and diversity may ultimately cause shifts in plant–pollinator networks (Zoller et al., <span>2023</span>), potentially triggering selection of phenotypes with reduced herkogamy or self-incompatibility (Bodbyl Roels & Kelly, <span>2011</span>; Cheptou, <span>2021</span>; Jacquemyn et al., <span>2012</span>; Opedal, <span>2019</span>).

Heterostyly is a genetically determined floral polymorphism expressed in the reciprocal positioning of female and male reproductive organs (Barrett, <span>2019</span>). It has evolved independently across at least 28 plant families (Barrett, <span>2019</span>). Populations of heterostylous plants comprise two (distylous species) or three (tristylous species) morphs with reciprocal lengths of style and anthers.

PSFs involve the modification of soil biological and abiotic properties by a given plant species that have downstream effects on the growth of future individuals in the same soil. These PSFs can be positive, negative or neutral, where plant performance is improved, reduced or unaffected, respectively, when grown in soil previously occupied by the same species compared with soil conditioned by other species (Bever et al., <span>1997</span>; Van der Putten et al., <span>2013</span>). Given this wide variation in PSF observed among species, there is considerable interest in developing a framework that can be used to predict the direction and magnitude of PSF responses as a function of plant species characteristics (de Vries et al., <span>2023</span>; Rutten & Allan, <span>2023</span>; Semchenko et al., <span>2022</span>). However, despite an abundance of studies exploring individual aspects of PSFs, our understanding of how plant traits and phylogeny, via associated effects on soil microbial communities, shape PSFs is still limited by the lack of comprehensive empirical tests.</p>\u0000<p>Plants modify their immediate environment in many ways and can shape the composition and diversity of microbial communities within their root zones (Grayston et al., <span>1998</span>; Hu et al., <span>2018</span>).

Previous studies indicate that root-associated fungi, especially arbuscular mycorrhizal fungi (AMF) and fungal pathotrophs, play an important role in determining PSFs (Cortois et al., <span>2016</span>; Semchenko et al., <span>2018</span>). Several studies show that these fungal guilds are strongly influenced by plant species identity (Frac et al., <span>2018</span>; Semchenko et al., <span>2018</span>) and that increased associations with AMF (Cortois et al., <span>2016</span>; Semchenko et al., <span>2018</span>) or fungal pathotrophs (Semchenko et al., <span>2018</span>; Wilschut et al., <span>2019</span>) lead to more positive and negative PSFs, respectively.

Many studies have shown that tree species diversity can foster forest productivity and carbon sequestration, resulting in positive diversity–productivity relationships (DPRs) (Brockerhoff et al., <span>2017</span>; Hooper et al., <span>2012</span>; Liang et al., <span>2016</span>). This result is now well-established in the literature and has been corroborated by many methodological approaches relating biodiversity and ecosystem functioning (BEF), including studies relying on forest inventories (Aussenac et al., <span>2021</span>; Liang et al., <span>2016</span>; Paquette & Messier, <span>2011</span>; Ratcliffe et al., <span>2016</span>; Toigo et al., <span>2015</span>) or empirical observations (Jucker et al., <span>2014</span>; Pretzsch et al., <span>2015</span>), experiments (Sapijanskas et al., <span>2014</span>; Toïgo et al., <span>2022</span>; Williams et al., <span>2017</span>), and simulations with process-based models (Bohn & Huth, <span>2017</span>; Maréchaux & Chave, <span>2017</span>; Morin et al., <span>2011</span>).</p>\u0000<p>DPRs have been assumed to result mostly from species complementarity in resources uptake and use-efficiency (Barry et al., <span>2019</span>), thus primarily depending on niche partitioning between species. In the case of forests, niche partitioning can occur through root spatial stratification (Cabal et al., <span>2024</span>), but most evidence concerns light uptake as forest dynamics are generally strongly driven by light availability (Pacala et al., <span>1996</span>; Rüger et al., <span>2020</span>), leading to a size-asymmetric competition (Cordonnier et al., <span>2019</span>; Schwinning & Weiner, <span>1998</span>).

Alpine ecosystems, with their high sensitivity to climate change, are an important starting point for analysing these effects. In general, alpine plant species are expected to undergo substantial shifts in habitat range and community structure (Engler et al., <span>2011</span>; Gottfried et al., <span>2012</span>; Thuiller et al., <span>2005</span>). For example, there can be typically observed an upward migration of lower-elevation species and an upward shift of the treeline, which illustrate the profound ecological transformations that are currently ongoing (Gottfried et al., <span>2012</span>; He et al., <span>2023</span>; Malfasi & Cannone, <span>2020</span>).</p>\u0000<p>However, such vegetation responses to climate change are not uniform. Species range adjustments are observed, with particularly fast dynamics at the treeline, and at lower alpine and nival belts (Cannone et al., <span>2007</span>; He et al., <span>2023</span>; Pauli et al., <span>2012</span>). Evidence suggests that the range of cold-adapted species is shrinking (Lamprecht et al., <span>2018</span>), while lower-elevation species migrate more rapidly upslope, which increases local species richness but also leads to more competition for space (Steinbauer et al., <span>2018</span>; Wipf et al., <span>2013</span>). This thermophilisation of assemblages (Gottfried et al., <span>2012</span>; Lamprecht et al., <span>2018</span>; Rumpf et al., <span>2018</span>) is driven especially by a prolongation of the growing season, increased energy availability, and changes in precipitation types (Filippa et al., <span>2019</span>; Pauli et al., <span>2012</span>; Vitasse et al., <span>2021</span>).</p>\u0000<p>Besides these direct climatic effects, vegetation distribution is also modulated by a complex interplay of other factors, including nutrient availability, soil development, and land use changes, while being mediated by individual adaptation and species interactions (Bektaş et al., <span>2021</span>; Bellard et al., <span>2012</span>; Bourgeois et al., <span>2019</span>; Martinez-Almoyna et al., <span>2020</span>; Rogora et al., <span>2006</span>; Tasser & Tappeiner, <span>2002</span>; Theurillat et al., <span>1998</span>; Wipf et al., <span>2015</span>). For instance, changes in land use, such as abandonment or intensification of pasture use, play a crucial role in the distribution of plant species, as they facilitate or suppress species and thus contribute to the homogenisation of communities, regardless of their natural elevation distribution (Gehrig-Fasel et al., <span>2007</span>; Hülber et al., <span>2020</span>; Niedrist et al., <span>2009</span>; Tasser et al., <span>2017</span>).</p>\u0000<p>The dynamic framework emerging from this interp","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"34 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of particular concern is pollution with microplastics (plastic particles <5 mm), which is recognized as an important threat to ecosystems worldwide (Sigmund et al., <span>2023</span>). Microplastics can contaminate terrestrial systems through soil amendments, plastic mulching, irrigation, flooding, atmospheric input and littering or street run-off (Rochman et al., <span>2019</span>), with both positive and negative effects on plant–soil systems (Boots et al., <span>2019</span>; Huang et al., <span>2019</span>). For instance, in European grasslands, the biomass of the native species <i>Daucus carota</i> can increase in response to the presence of microplastic films in the soil (Huang et al., <span>2019</span>; Lozano, Lehnert, et al., <span>2021</span>). This effect is thought to occur because plastic particles could improve soil properties such as porosity and aeration (de Souza Machado et al., <span>2019</span>; Lozano, Aguilar-Trigueros, et al., <span>2021</span>). By contrast, the biomass of the native species <i>Lolium perenne</i> may decrease (Boots et al., <span>2019</span>), presumably due to toxic effects from microplastic leachates. However, not only are native plants affected by microplastics, invasive plants may potentially benefit from microplastic pollution due to traits that enhance their ability to thrive in polluted environments (Lozano & Rillig, <span>2024</span>). Research shows that microplastic fibres can enhance the growth of species of invasive character such as the range-expanding species <i>Calamagrostis epigejos</i> (Lozano & Rillig, <span>2020</span>). Microplastic beads can increase fine root biomass and photosynthesis efficiency in invasive plants compared to native species under dry–wet water cycles (Zhang et al., <span>2024</span>). Also, microplastic fragments may have negligible effects on the growth of the invasive plant <i>Solidago canadensis</i>, while having negative effects on its native counterpart <i>Solidago decurrens</i> (Li et al., <span>2024</span>). This advantage can be expected, as invasive species could benefit more from the novel environmental conditions created by microplastics, such as changes in soil water content, aeration, microbial activity and aggregation (de Souza Machado et al., <span>2019</span>; Lozano, Aguilar-Trigueros, et al., <span>2021</span>). In addition, invasive species can possess advantageous traits that might help them to avoid or better tolerate microplastic pollution (Lozano & Rillig, <span>2024</span>), enabling them to thrive in human-altered environments (Montesinos, <span>2021</span>), which are most likely the ones exposed to higher levels of plastic pollution. Nonetheless, microplastics can also inhibit the establishment of invasive plants like <i>Amaranthus palmeri</i> (Meng ","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"4 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
