Although on the basis of evolutionary theory, the patterns and drivers of intraspecific functional variation remain largely underexplored. In ants, pilosity and body size are morphological traits associated to thermoregulation and heat tolerance, which are critical concerns in the context of global warming. Here, we focused on the dominant ant &lt;i&gt;Camponotus crassus&lt;/i&gt; to investigate trait variation and its potential drivers across a latitudinal gradient in the Brazilian Cerrado savanna.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Location&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Brazilian Cerrado savanna.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Taxon&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;&lt;i&gt;Camponotus crassus&lt;/i&gt; Mayr, 1862 (Hymenoptera: Formicidae).&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;We measured mesosoma pilosity and body size of &lt;i&gt;C. crassus&lt;/i&gt; across multiple sites, and evaluated their relationship with &lt;i&gt;temperature, rainfall, solar radiation, vegetation&lt;/i&gt; and &lt;i&gt;sugar-rich resource&lt;/i&gt; variables. We also assessed morphological and genetic covariation to search for possible phenotypic plasticity or adaptation in &lt;i&gt;C. crassus&lt;/i&gt;.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Only sugar-rich resources were found to significantly influence &lt;i&gt;C. crassus&lt;/i&gt; pilosity. Specifically, a negative relationship between ant pilosity and &lt;i&gt;sugar-rich resources&lt;/i&gt; (i.e., proportion of plants with extrafloral nectaries and hemipteran trophobionts) was found. No covariation between pilosity and genetic dissimilarities was observed, suggesting phenotypic plasticity. None of the variables were significant to predict body size, while this trait positively covaried with genetics.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Main Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Our findings suggest resource availability as a critical factor for species thermoregulation under environmental change, a hypothesis previously reported in the literature. We emphasise the importance of examining intraspecific variation and phenotypic plasticity across large geographic scales, particularly under the scenario of rapid global change and the current threat to Cerrado savanna.

A working plant checklist was compiled for ACA in order to assign trait values to pollen types and vegetation taxa. This was done for two widely used methods of pollen aggregation schemes (coarse and fine pollen type depend on the level of pollen identification). The functional signatures of pollen and vegetation samples were compared both at the taxon and community levels, using large-scale trait and vegetation databases, for the six traits of the global spectrum of plant form and function (i.e., plant height, seed mass, leaf area, specific leaf area, nitrogen content per leaf mass, and stem-specific density).&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Trait distributions and bivariate trait relationships were broadly similar for pollen types and vegetation taxa, which is also the case for the multivariate spaces of the global spectrum of plant form and function. At the community scale, the trait values weighted by taxon abundance significantly differed among biomes, and these differences were consistent for both pollen aggregation schemes and extant.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Main Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;The pollen aggregation scheme does not impact the organisation of the functional space of the global spectrum of plant form and function, which compares well with that based on species actually present in the vegetation plots. This is also true at the community scale. These findings are very promising for improving climate and biome reconstructions from pollen assemblages and pave the way to a “pollen functional biogeography”.&lt;/p&gt;\u0000 ","PeriodicalId":15299,"journal":{"name":"Journal of Biogeography","volume":"52 5","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jbi.15100","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143846099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
