Individual flowering time and maternal fecundity in a summer-flowering mediterranean shrub: making the right prediction for the wrong reason

Author(s): Herrera, Carlos M.
Description: The study of the reproductive biology of those few Mediterranean perennials that flower during the summer drought period may provide an indirect test of the adaptive value of prevailing off-summer flowering in Mediterranean-climate plant communities. This paper presents a study of the c...

Historical effects and sorting processes as explanations for comtemporary ecological patterns: character syndromes in mediterranean woody plants

Author(s): Herrera, Carlos M.
Description: —Ecological patterns are not only a consequence of adaptive processes, but also influenced by phylogenetic constraints, historical effects, and sorting processes. In contrast to the attention paid to the influence of phylogeny on interspecific ecological patterns, historical effects and ...

Seed Dispersal by Animals: A Role in Angiosperm Diversification?

Author(s): Herrera, Carlos M.
Description: Seed dispersal by animals has sometimes been considered one of the factors helping to explain angiosperm diversification. Three predictions related to this hypothesis are examined here, namely, (1) biotic seed dispersal is a feature unique to angiosperms, or this group exhibits it proportionally mor...

Interspecific Variation in Fruit Shape: Allometry, Phylogeny, and Adaptation to Dispersal Agents

Author(s): Herrera, Carlos M.
Description: nvestigations on fruit and fruiting characteristics of animal—dispersed, fleshy—fruited plants have been generally interpreted in terms of adaptations by plants to dispersal agents. Most often, these studies did not formulate non—adaptive, alternative null hypotheses, and the potential influence of ...

Dissecting Factors Responsible For Individual Variation in Plant Fecundity

Author(s): Herrera, Carlos M.
Description: This paper analyses, on an individual plant basis, the various components determining seed production in the evergreen shrub Lavandula latifolia (Labiatae), in order to estimate their relative contributions to individual differences in fecundity. The relationships between fecundity and age, size, an...

The Fruiting Ecology of Osyris Quadripartita: Individual Variation and Evolutionary Potential

Author(s): Herrera, Carlos M.
Description: The fruiting ecology of Osyris quadripartita (Santalaceae), a hemiparasitic evergreen shrub, was studied over a 4—yr period in a Mediterranean scrubland of southern Spain. In addition to describing the natural history of seed dispersal in this species, objectives of the study were (1) to document pa...

Vertebrate frugivores and their interaction with invertebrate fruit predators: supporting evidence from a Costa Rican dry forest

Author(s): Herrera, Carlos M.
Description: Fruit-eating vertebrates may have a significant impact on the population sizes of insect fruit predators that remain inside the fruit after ripening, and it may be predicted that the disappearance or marked reduction of a population of frugivorous vertebrates will lead to a dr...

Frugivory and seed dispersal by carnivorous mammals, and associated fruit characteristics, in undisturbed Mediterranean habitatsFrugivory and seed dispersal by carnivorous mammals, and associated fruit characteristics, in undisturbed Mediterranean habitats

Author(s): Herrera, Carlos M.
Description: The role of carnivorous mammals (Order Carnivora) in seed dispersal has remained virtually unexplored, despite the well-known fact that these animals commonly ingest fleshy fruits and defecate their seeds. This paper presents data on the dispersal of seeds by carnivores in an extensi...

Daily patterns of pollinator activity, differential pollinating effectiveness, and floral resource availabifity, flowering Mediterranean shrub

Author(s): Herrera, Carlos M.
Description: This study examined the daily activity patterns of the pollinators of Lavandula latifolia (Labiatae), a summer-flowering, insect-pollinated evergreen shrub of Med­ iterranean woodlands. The question is addressed, What is the degree of matching between the daily floral cycle of L. latifolia and the d...
