Linking environmental adaptation and genetic structure to the biogeography of flower colour lineages in <i>Lysimachia monelli</i> (Primulaceae) Open
Reproductive traits such as flower colour can have a profound influence on the diversification of plant species, making understanding their evolutionary ramifications one of the foremost challenges for evolutionary biologists. Lysimachia m…

Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community Open
Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenolo…

Rapid detection of RNase‐based self‐incompatibility in <i>Lysimachia monelli</i> (Primulaceae) Open
Premise Primroses famously employ a system that simultaneously expresses distyly and filters out self‐pollen. Other species in the Primulaceae family, including Lysimachia monelli (blue pimpernel), also express self‐incompatibility (SI), b…

Transcontinental patterns in floral pigment frequencies among animal-pollinated species Open
Flower coloration arises primarily from pigments that serve dual functions: attracting pollinators and mitigating environmental stresses. Among major flower pigment groups, anthocyanins and UV-absorbing phenylpropanoids are particularly no…

Green flowers need yellow to get noticed in a green world Open
Background and Aims Flower colour is a key feature in plant–pollinator interactions that makes the flowers visible amid the surrounding green vegetation. Green flowers are expected to be scarcely conspicuous to pollinators; however, many o…

Pollinator response to yellow <span>UV</span>‐patterned versus white <span>UV</span>‐patternless flower dimorphism in <i>Anemone palmata</i> Open
Flower colour polymorphisms are uncommon but widespread among angiosperms and can be maintained by a variety of balancing selection mechanisms. Anemone palmata is mostly yellow‐flowered, but white‐flowered plants coexist in some population…

Better soon than never: climate change induces strong phenological reassembly in the flowering of a Mediterranean shrub community Open
Background and Aims Flowering is a key process in the life cycle of a plant. Climate change is shifting flowering phenologies in the Northern Hemisphere, but studies with long data series at the community level are scarce, especially those…

Genomic-guided conservation actions to restore the most endangered conifer in the Mediterranean Basin Open
Species with extremely small population sizes are critically endangered due to reduced genetic diversity, increased inbreeding, and the added threat of hybridization. Genomic tools significantly advance conservation by revealing genetic in…

Can a flower color ancestral polymorphism transcend speciation? Open
Polymorphisms are common in nature, but they are rarely shared among closely related species. They could originate through convergence, ancestral polymorphism, or introgression. Although shared neutral genomic variation is commonplace, ver…

Multiple pre‐ and postzygotic components of reproductive isolation between two co‐occurring <i>Lysimachia</i> species Open
Summary 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 found t…

Molecular approaches reveal speciation between red- and blue-flowered plants in the Mediterranean <i>Lysimachia arvensis</i> and <i>L. monelli</i> (Primulaceae) Open
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 arvensis and L. monel…

Major Flower Pigments Originate Different Colour Signals to Pollinators Open
Flower colour is mainly due to the presence and type of pigments. Pollinator preferences impose selection on flower colour that ultimately acts on flower pigments. Knowing how pollinators perceive flowers with different pigments becomes cr…

Molecular approaches reveal speciation between red and blue flowered plants in the Mediterranean<i>Lysimachia arvensis</i>and<i>Lysimachia monelli</i>(Primulaceae) Open
Flower colour constitutes a pivotal evolutionary force in speciation. The Mediterranean Lysimachia arvensis and L. monelli are morphologically variable species having both blue or red flowered plants. Previous studies suggested that L. arv…

Reproductive Assurance Maintains Red-Flowered Plants of Lysimachia arvensis in Mediterranean Populations Despite Inbreeding Depression Open
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 mating and p…

Do visual traits honestly signal floral rewards at community level? Open
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 them. However, som…
