The link between selfing and greater dispersibility in a heterocarpic Asteraceae
(Wiley-Blackwell, 2018-12)
Premise of the Study: Although an evolutionary link between breeding system and dispersibility has been proposed, to date empirical data and theoretical models of plants show contrasting trends. Methods: We tested two ...

Heritabilities of lateral and vertical herkogamy in Lysimachia arvensis
(Wiley, 2019-01-07)
Herkogamy, spatial separation between stigma and anthers within a flower, is important in regulating plant-mating systems. We studied phenotypic variation and heritability of herkogamy traits in Lysimachia arvensis (=Anagallis ...

Molecular approaches reveal speciation between red- and blue-flowered plants in the Mediterranean Lysimachia arvensis and L. monelli (Primulaceae)
(Linnean Society of London, 2022)
Flower colour has played a decisive role as an evolutionary force in many groups of plants by driving speciation. A well-known example of colour polymorphism is found across the Mediterranean populations of Lysimachia ...

The role of lateral and vertical herkogamy in the divergence of the blue- And red-flowered lineages of Lysimachia arvensis
(Oxford University Press, 2020-06-01)
Background and Aims: Herkogamy, or anther-stigma separation, is known to reduce self-pollen deposition, but little is known about the relative efficacy of different modes or conformations of herkogamy. We assessed the ...

Uncertain pollination environment promotes the evolution of a stable mixed reproductive system in the self-incompatible Hypochaeris salzmanniana (Asteraceae)
(Oxford University Press, 2017)
Background and aims The transition from outcrossing to selfing is a repeated pattern in angiosperm diversification and according to general theory this transition should occur quickly and mixed reproductive systems should ...

Flower colour segregation and flower discrimination under the bee vision model in the polymorphic Lysimachia arvensis
(Taylor & Francis, 2020-07-03)
Floral colour determines pollinator behaviour, strongly affecting plant-mating systems. Lysimachia arvensis has blue- and red-flowered plants and colour inheritance remains largely unknown. A control of floral colour based ...

Do visual traits honestly signal floral rewards at community level?
(Wiley-Blackwell, 2021-02)
The high variability observed in floral traits has been interpreted as resulting from the adaptation of plants to pollinators, as the latter present innate preferences for specific floral traits and impose selection over ...

Reproductive Assurance Maintains Red-Flowered Plants of Lysimachia arvensis in Mediterranean Populations Despite Inbreeding Depression
(Frontiers Media, 2020)
Flower color polymorphism, an infrequent but phylogenetically widespread condition in plants, is captivating because it can only be maintained under a few selective regimes but also because it can drive intra-morph assortative ...

Multiple pre- and postzygotic components of reproductive isolation between two co-occurring Lysimachia species
(Wiley-Blackwell, 2023)
Genetic divergence between species depends on reproductive isolation (RI) due to traits that reduce interspecific mating (prezygotic isolation) or are due to reduced hybrid fitness (postzygotic isolation). Previous research ...
