Post-floral perianth functionality: contribution of persistent sepals to seed development in Helleborus foetidus (Ranunculaceae)

Author(s): Herrera, Carlos M.
Description: The perianth persists after flowering in many plants, yet its post-floral functionality has been little investigated, and the few studies available provide ambiguous evidence. This paper tests the hypothesis that the green persistent sepals of the perennial herb, Helleborus foetidus, contribute to t...

Plant generalization on pollinators: species property or local phenomenon?

Author(s): Herrera, Carlos M.
Description: Despite recent increased interest in the frequency and evolutionary consequences of generalization in plant–pollinator systems, little is known on whether plant generalization on pollinators actually is a species-level trait. This paper addresses the following questions for the insect-pollinated shr...

Distribution ecology of pollen tubes: fine-grained, labile spatial mosaics in southern Spanish Lamiaceae

Author(s): Herrera, Carlos M.
Description: • Patterns of intraspecific variation in the number of pollen tubes per style in naturally pollinated plants are poorly known, yet that information is essential for assessing the frequency of occurrence and evolutionary implications of microgametophyte com- petition in the wild. • This paper analyse...

Correlated evolution of fruit and leaf size in bird-dispersed plants: species-level variance in fruit traits explained a bit further?

Author(s): Herrera, Carlos M.
Description: The astounding morphological diversity exhibited by the fruits of vertebrate-dispersed plants has been traditionally interpreted as the adaptive outcome of divergent selective pressures exerted on plants by the broad array of frugivorous animals involved in seed dispersal. Although the selective cap...

Topsoil properties and seedling recruitment in Lavandula latifolia : stage-dependence and spatial decoupling of influential parameters

Author(s): Herrera, Carlos M.
Description: This paper investigates the influence of topsoil texture and chemistry on long-term patterns of seedling recruitment in Lavandula latifolia (Labiatae), an evergreen Mediterranean shrub. The questions addressed are: (1) Are spatial patterns of seedling emergence and survi...

Censusing natural Microgametophyte populations:variable spatial mosaics and extreme fine-graininess in winter-flowering Helleborus foetidus (Ranunculaceae)

Author(s): Herrera, Carlos M.
Description: Little is known about patterns and correlates of variation in microgametophyte populations for naturally pollinated plants, yet this information is critical for evaluating the prevalence and potential evolutionary significance of gametophyte competition in the wild. This paper analyzes spatial and t...
