Moeneclaey, IrisSchelfhout, StephanieBlondeel, HabenVancoillie, FriekeVerheyen, KrisBaeten, Lander2024<jats:title>Abstract</jats:title><jats:sec><jats:title>Questions</jats:title><jats:p>Increased soil phosphorus (P) availability in fertilized grasslands can drive both community degradation and delayed community recovery upon agricultural abandonment. Beyond describing grassland community patterns along gradients in P availability, it remains unclear how individual species with different strategies respond to increasing phosphorus. Here we studied intraspecific variability of leaf functional traits in response to soil phosphorus, for species with contrasting resource‐use strategies.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>We set up a pot experiment with communities containing four species, assembled from a pool of 20 mesotrophic grassland species growing along a soil P gradient. Species selection included various growth forms (grasses vs forbs) and resource‐use strategies (acquisitive vs conservative resource use). We measured three variables characterizing the (a)biotic environmental context: bioavailable soil P concentration, total community biomass as a proxy for the intensity of competition, and the proportional biomass of a species in the community as a proxy for its competitive dominance. We investigated the effect of this environmental context on the expression of two leaf traits, specific leaf area (SLA) and leaf dry matter content (LDMC).</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>We found an acquisitive trait expression within species (increase in SLA and decrease in LDMC) in response to increased soil P supply and a conservative trait expression (decrease in SLA and increase in LDMC) in response to an increase in total community biomass. Importantly, the trait responses to the environmental context were generally consistent for species representing very different resource‐use strategies and growth forms.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Species responded with a shift from an acquisitive to a conservative trait expression in response to limited resources; i.e., driven by a decrease in soil phosphorus concentration or an increase in total community biomass. Unexpectedly, the intraspecific variability in response to the changing environmental conditions was not clearly mediated by the species’ strategy. These findings show that plant ecological strategies are probably not the main driver for intraspecific trait variability in an experimental grassland community.</jats:p></jats:sec>application/pdfhttps://biblio.ugent.be/publication/01HRVK5SHD7WVZVBBQHK1D2X20http://hdl.handle.net/1854/LU-01HRVK5SHD7WVZVBBQHK1D2X20http://doi.org/10.1111/jvs.13244https://biblio.ugent.be/publication/01HRVK5SHD7WVZVBBQHK1D2X20/file/01HRVK7CX2F1BBM4PMJHWNNCQYengWileyNo license (in copyright)info:eu-repo/semantics/restrictedAccessJournal of Vegetation ScienceISSN: 1100-9233ISSN: 1654-1103Plant ScienceEcologyLeaf trait variation in grassland plant species in response to soil phosphorusjournalArticleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion
