Biodiversity encompasses multiple attributes such as the richness and abundance of species (taxonomic diversity), presence different evolutionary lineages (phylogenetic variety growth forms resource use strategies (functional diversity). These biodiversity do not necessarily relate to each other may have contrasting effects on ecosystem functioning. However, how they simultaneously influence provision functions related carbon, nitrogen, phosphorus cycling (multifunctionality) remains...
Abstract Pollinators tend to be preferentially attracted large floral displays that may comprise more than one plant in a patch. Attracting pollinators thus not only benefits individuals investing advertising, but also other plants patch through ‘magnet’ effect. Accordingly, there could an indirect fitness advantage greater investment costly by kin-structured groups when of unrelated individuals. Here, we seek evidence for this strategy manipulating relatedness the Moricandia moricandioides...
Background and Aims Brassicaceae is one of the most diversified families in angiosperms. However, species from this family exhibit a very similar floral bauplan. In study, we explore morphospace, examining how corolla shape variation (an estimation developmental robustness), integration disparity vary among phylogenetically related species. Our aim to check whether these attributes have evolved despite its apparent morphological conservation, test role pollinators driving evolution. Methods...
Abstract Phenotypic plasticity, the ability of a genotype producing different phenotypes when exposed to environments, may impact ecological interactions. We study here how within-individual plasticity in Moricandia arvensis flowers modifies its pollination niche. During spring, this plant produces large, cross-shaped, UV-reflecting lilac attracting mostly long-tongued large bees. However, unlike most co-occurring species, M. keeps flowering during hot, dry summer due key vegetative traits....
A range of hypothesized evolutionary pathways has been proposed for describing the evolution dioecy. However, links between other sexual systems not directly involved in dioecy remain largely unexplored, and hence, a comprehensive picture transitions is still lacking. Here, we explored diversity Asteraceae, largest family flowering plants, where almost all are present. We used phylogenetic approach to build model systems. The best nine transitions, including those from hermaphroditism...
Molecular phylogenies are being increasingly used to better understand the mechanisms structuring natural communities. The prevalent theory is that environmental factors and biotic interactions promote phylogenetic clustering overdispersion of plant communities, respectively. However, both filtering very likely interact in most jointly affecting community structure. We asked following question: How do filters affect structure communities across gradients?Eleven Stipa tenacissima L....
Most of the diversity in pseudanthia Asteraceae is based on differential symmetry and sexuality its flowers. In Anacyclus, where there are (1) homogamous capitula, with bisexual, mainly actinomorphic pentamerous flowers; (2) heterogamous peripheral zygomorphic, trimerous long-/short-rayed female flowers, floral ontogeny was investigated to infer their origin. Floral morphology were studied using scanning electron microscope light techniques Disc subtended by paleae, initiate acropetally....
Organisms usually show intercorrelations between all or some of their components leading to phenotypic integration, which may have deep consequences on the evolution phenotypes. One main difficulties with integration studies is how correct measures for size. This has been considered a challenging task. In this paper, we introduce an R package (PHENIX: PHENotypic Integration indeX), in provide functions estimate size-controlled index, bootstrapping method calculate confidence intervals, and...
Positive and negative plant-plant interactions are major processes shaping plant communities. They affected by environmental conditions evolutionary relationships among the interacting plants. However, generality of these factors as drivers pairwise their combined effects remain virtually unknown. We conducted an observational study to assess how (altitude, temperature, irradiance rainfall), dispersal mechanism beneficiary species co-occurrence in 11 Stipa tenacissima steppes located along...
Chromosome number changes during the evolution of angiosperms are likely to have played a major role in speciation. Their study is utmost importance, especially now, as probabilistic model available chromosome within phylogenetic framework. In present study, likelihood models were fitted largest family flowering plants, Asteraceae. Specifically, supertree this was used reconstruct ancestral and infer genomic events. Our approach inferred that n = 9. Also, according best explained our data,...

Summary The evolutionary pathways leading to the heterostylous syndrome are not well understood, and models concerning origins of distyly differ in order which reciprocal herkogamy self‐incompatibility evolve. We investigated evolution breakdown Plumbaginaceae, a family with considerable diversity floral traits reproductive systems. Using Bayesian Markov chain Monte Carlo analyses stochastic character mapping, we examined assembly based on well‐resolved phylogeny 121 species Plumbaginaceae...
Abstract New inference techniques, such as supertrees, have improved the construction of large phylogenies, helping to reveal tree life. In addition, these phylogenies enhanced study other evolutionary questions, whether traits evolved in a neutral or adaptive way, what factors influenced diversification. However, supertrees usually lack branch lengths, which are necessary for all issues be investigated. Here, divergence times within largest family flowering plants, namely Asteraceae,...
From an ancestor with bisexual flowers, plants unisexual or even individuals have evolved in different lineages of angiosperms. The Asteraceae tribe Inuleae includes hermaphroditic, monoecious, dioecious, and gynomonoecious species. Gynomonoecy, the sexual system which female flowers occur on same plant, is prevalent Asteraceae. We inferred one large gene phylogeny (ndhF) two supertrees to investigate whether gynomonoecy was a stage evolution from hermaphroditism monoecy. identified...
Genome size variation and polyploidy incidence
Premise of research. Sex allocation theory considers that, given limited resources, a trade-off must exist between allocations to competing functions, such as accessory and primary sexual organs, or male female organs. However, phenotypic genotypic correlations floral components have often been found be positive. A view resource from phenotypic-integration perspective could shed light on these apparently paradoxical results. Resource allocation, not only metric traits, can also significantly...
•In heterocarpy, fruits with different morphologies have been associated alternative strategies of dispersal, germination, dormancy, and seedling competitive ability. In heterocarpic species, it is common to find or dispersal syndromes. The advantage nondispersing has frequently attributed their larger size, but recent studies suggested that this could also be mediated by germination time. main objective our study was investigate which factor, fruit type time, most affects plant performance...
Abstract Sex allocation theory forecasts that larger plant size may modify the balance in fitness gain both genders, leading to uneven optimal male and female allocation. This reasoning can be applied flowers inflorescences, because increase flower or inflorescence differentially benefit different gender functions, thus favour preferential specific floral structures. We investigated how influenced sexual expression reproductive success monoecious Tussilago farfara , by measuring patterns of...
Premise of research. Interspecific hybridization was hypothesized to explain the remarkable floral phenotype variation found in overlapping areas distribution for several Anacyclus species. We aimed investigate genome size natural populations three diploid species with special emphasis their contact explore patterns as additional evidence supporting current these areas.Methodology. Flow cytometry used estimate 564 individuals complex A. clavatus, homogamos, and valentinus from 30 sites....
Ray flowers commonly observed in daisies' flowering heads are a well-known example of advertising structures for enhancing pollinator attraction. Despite this, ray loss has occurred multiple lineages, which still rely on pollinators, suggesting that rayless phenotypes could also be adaptive animal-pollination. Here, we investigate the benefits and costs these specialized floral by comparing rayed two hybridizing closely related species.We assessed advantages production terms visitor's...
The reproductive success of plants depends both on their phenotype and the local neighbourhood in which they grow. Animal-pollinated may benefit from increased visitation when surrounded by attractive conspecific individuals, via a “magnet effect.” Group attractiveness is thus potentially public good that can be exploited with selfish exploitation predicted to depend genetic relatedness within group. Petal colour costly trait involved floral signalling advertising pollinators. Here, we...
