ABSTRACT Plant responses to environmental heterogeneity depend on life‐history traits, which could relate phenotypical and genetic characteristics. To elucidate this relationship, we examined the variation in population genetics functional traits of short‐ long‐lived Artemisia species that are co‐occurring steppes Mongolia. Mongolian represent stressful water‐limited habitats, demanding phenotypic modifications short term and/or adaptation long term. However, detailed knowledge is missing about both plant differentiation, their interrelationships temperate grasslands. Here, investigated 21 populations widely distributed subshrub frigida herbaceous biennial scoparia . Genetic was assessed with newly developed simple sequence repeats (SSRs) markers. Functional trait data were collected from each individual, variables for population. We detected significantly higher diversity ( H E = 0.86) compared perennial 0.79). For species, largest share partitioned within (96%). Population structure A. weak, while showed some spatial structure, impacted by geographical factors, soil nutrients, precipitation amount. Morphology‐related (i.e., height) predominantly associated rather than variation, whereas physiology‐related specific leaf area [SLA]) partly genetically determined.

Summary By modifying the biotic and abiotic properties of soil, plants create soil legacies that can affect vegetation dynamics through plant–soil feedbacks (PSF). PSF are generally attributed to reciprocal effects biota, but these interactions also drive changes in identity, diversity abundance metabolites, leading more or less persistent chemical whose role mediating has rarely been considered. These may interact with microbial nutrient species coexistence. Given ecological importance between other organisms, a better understanding is needed community ecology. In this Viewpoint, we aim to: highlight belowground for PSF; define integrate into research by clarifying how metabolome contribute discuss functional traits help predict interactions; propose an experimental approach quantify plant responses solution metabolome; describe testable framework relying on root economics seed dispersal they could respond legacies.

SUMMARY Character displacement refers to the process by which species diverge more in sympatry due competition for resources. This competition‐driven speciation can also occur within populations, known as intraspecific character (ICD). ICD promote divergence influencing or encouraging evolution of alternative phenotypes. Despite its significance, remains understudied and requires further exploration. In this study, we investigate how influences genetic morphological differentiation sympatric allopatric populations. We focused on Quercus serrata (in China Japan) Q. var. brevipetiolata (found only China), belong a small monophyletic group oak nested Section (white oaks). Using markers, detected between Chinese Japanese populations diversification China, with asymmetric historical gene flow primarily from (the earlier diverged species) later variety). Although did not differ leaf variation, analyzed through geometric morphometric method (GMM) traditional method, revealed greater trait variation sympatry. addition, found an allometric growth relationship size mass , area decreasing disproportionately mass. suggests resource trade‐off, where var . variety, adopts resource‐conservative traits Further analysis environmental factors supports these findings, while along climate gradients showed significant responses regardless conditions. neutral markers are insufficient capture selection‐driven adaptive differentiation, inferred that is progressing towards ecological serrata. Overall, our results highlight role driving resource‐use strategies response competitive pressures.

In this study, we investigated role of factors associated with arid conditions shaping phenotypic an annual plant, Anastatica hierochuntica, across several populations found along aridity gradient and multiple spatial scales. Utilizing both field surveys a net house experiment, assessed effects on trait variability within between populations.

Convergence was also observed plant’s electrolyte leakage concerning soil salinity at specific sites. Phenotypic plasticity pivotal maintaining variability, increasing salinity, SLA decreasing leaf number rising aridity. conclusion, our findings underscore adaptive significance especially plasticity, Notably, did not consistently diminish stressful settings, emphasizing value flexible such environments.

Abstract The study of tree species coexistence is crucial to understand the assembly forest communities. In this context, trees adjust their traits in response interactions with other and, specifically, as a result competition for resources. Further, mycorrhizal fungal diversity and associations are important drivers ecosystem functioning forests, but role intraspecific trait variation has been disregarded. Here, we studied diversity. We sampled 3200 leaves from 640 belonging 10 native, deciduous experiment Central Germany. This relies on combination gradients richness associations. To handle large amounts leaf samples, acquired leaf‐level spectral data used deep learning predict values five economics spectrum (LES): specific area, dry matter content, carbon nitrogen ratio, content phosphorus content.
