Does size matter? Pollination biology of Aristolochia sessilifolia (Aristolochiaceae) [PDF]

Plant Ecology and Evolution
Background and aims – The morphology of flowers with specialized pollination acts as a pollinator filter, resulting in compatibility between the flower and its visitors. These characteristics can influence plant diversity, and studying these interactions

Introgression despite minimal hybridization: mating system modulates phenotypic associations with introgression in Clarkia

New Phytologist, Volume 250, Issue 4, Page 2619-2633, May 2026.
Summary Secondary contact between incipient species provides the opportunity to understand how trait divergence restricts gene flow. While mating system transitions are particularly common and involve a suite of phenotypic changes, the extent to which these changes influence gene flow during speciation is poorly understood.

Fecundity Effects of Dichogamy in an Asynchronically Flowering Population: a Genetic Model [PDF]

Annals of Botany, 1998
Abstract Timing of pollen presentation and ovule maturation at the level of the flower, individual and population may exert a profound influence on individual fitness and population structure. We explored the evolutionary consequences of asynchrony in flowering in a population of dichogamous plants, making use of a genetic model to represent pollen ...

Do dichogamy and herkogamy reduce sexual interference in a self‐incompatible species? [PDF]

Functional Ecology, 2010
Summary 1. Dichogamy and herkogamy respectively represent the temporal and spatial separation of male and female reproductive functions. They are regarded as mechanisms to avoid selfing, to promote outcrossing and, particularly in self‐incompatible plants, to reduce sexual interference.

Demographic History and Genetic Diversity of Rātā Moehau (Metrosideros bartlettii; Myrtaceae), a Critically Endangered Aotearoa New Zealand Endemic Tree

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Rātā Moehau (Metrosideros bartlettii), a critically endangered tree endemic to Aotearoa New Zealand, is represented by only 14 wild individuals. We assembled its first genome, analysed genetic diversity in wild and cultivated individuals and found long‐term population decline and reduced diversity in cultivated plants—providing key insights to support ...

Timing is everything: Dichogamy and pollen germinability underlie variation in autonomous selfing among populations [PDF]

American Journal of Botany, 2018
Premise of the StudyThe evolution of multiple floral traits often underlies the transition from outcrossing to selfing. Such traits can influence the ability to self, and the timing at which selfing occurs, which in turn affects the costs of selfing. Species that display variation in autonomous selfing provide an opportunity to dissect the phenotypic ...

Dichogamy correlates with outcrossing rate and defines the selfing syndrome in the mixed-mating genus Collinsia [PDF]

Annals of Botany, 2011
How and why plants evolve to become selfing is a long-standing evolutionary puzzle. The transition from outcrossing to highly selfing is less well understood in self-compatible (SC) mixed-mating (MM) species where potentially subtle interactions between floral phenotypes and the environment are at play.

Effect of Climatic Conditions on Flowering of Walnut Genotypes in Romania [PDF]

Journal of Nuts, 2017
The timing and lowering type of walnut genotypes (Juglans regia L.) is one of the important factors that lead to high and constant production. Therefore, the selection of homogame and spring frost tolerant genotypes has been among the most important ...
