Geographical Structuring of Genetic Diversity Across the Whole Distribution Range of Narcissus longispathus, a Habitat-specialist, Mediterranean Narrow Endemic

Description: † Background and Aims High mountain ranges of the Mediterranean Basin harbour a large number of narrowly endemic plants. In this study an investigation is made of the levels and partitioning of genetic diversity in Narcissus longispathus, a narrow endemic of south-eastern Spanish moun...

Yeasts in nectar of an early-blooming herb: Sought by bumble bees, detrimental to plant fecundity

Description: Through their effects on physicochemical features of floral nectar, nectardwelling yeasts can alter pollinator behavior, but the effect of such changes on pollination success and plant reproduction is unknown. We present results of experiments testing the effects of nectar yeasts on foraging pattern...

Comparative floral and vegetative differentiation between two European Aquilegia taxa along a narrow contact zone

Description: As a first step in determining the identity and relative importance of the evolutionary forces promoting the speciation process in two closely related European taxa of Aquilegia, we investigated the levels of morphological variation in floral and vegetative characters over the narrow region where thei...

Geographical context of floral evolution: towards an improved research programme in floral diversification

Description: The diversification of animal-pollinated angiosperms is related to divergence in floral characteristics promoted by adaptations to different pollinators. According to prevailing evolutionary theory, this mac- roevolutionary pattern results from adaptive local or regional differentiation of pollina...

Mating system, sex ratio, and persistence of females in the gynodioecious shrub Daphne laureola L. (Thymelaeaceae)

Description: Although in gynodioecious populations male steriles require a fecundity advantage to compensate for their gametic disadvantage, southern Spanish populations of the long-lived shrub Daphne laureola do not show any fecundity advantage over hermaphrodites in terms of seed production and early seedling ...

Herkogamy and Mating Patterns in the Self-compatible Daffodil Narcissus longispathus

Description: • Background and Aims Floral design in self-compatible plants can influence mating patterns. This study invest- igated Narcissus longispathus, a self-compatible bee-pollinated species with wide variation in anther–stigma separation (herkogamy), to determine the relationship between variation in this...

Epigenetic Differentiation Persists after Male Gametogenesis in Natural Populations of the Perennial Herb Helleborus foetidus (Ranunculaceae)

Description: Despite the importance of assessing the stability of epigenetic variation in non-model organisms living in real-world scenarios, no studies have been conducted on the transgenerational persistence of epigenetic structure in wild plant populations. This gap in knowledge is hindering progress in the...

Epigenetic variation predicts regional and local intraspecific functional diversity in a perennial herb

Description: The ecological significance of epigenetic variation has been generally inferred from studies on model plants under artificial conditions, but the importance of epigenetic differences between individuals as a source of intraspecific diversity in natural plant populations remains essentially unknown. ...
