Humaña, Ana María; Cisternas, Mauricio A.; Valdivia, Carlos E. (ELSEVIER, 2008)The breeding system determines different ways whereby seeds will be produced, and the degree of dependency of plants on pollinators for seed set. The genus Chloraea (Orchiclaceae) has its main center of diversity in southern ...

Valdivia, Carlos E.; Simonetti Zambelli, Javier Andrés (2007)Habitat fragmentation reduces frugivorous bird abundance. Such a reduction may lead to a reduction in seed dispersal, thereby compromising seedling recruitment rate with far reaching consequences for plant population ...

Valdivia, Carlos E.; Simonetti Zambelli, Javier Andrés; Henríquez, Carolina (SPRINGER, 2006-05)We studied the pollination and reproductive success in continuous and fragmented populations of Lapageria rosea, a self-compatible plant endemic to temperate forests of Chile. Pollinator abundance, visitation rates, flower ...

Valdivia, Carlos E.; Niemeyer Marich, August (BLACKWELL, 2006-11)Correlation among phenotypic traits may be explained by correlational selection, the simultaneous selection of more than one trait, or by genetic and/or developmental factors. In Escallonia myrtoidea, a tree with scented ...

Valdivia, Carlos E.; Niemeyer Marich, August (2007)The effect of mutualists (i.e. pollinators) and antagonists (i.e. herbivores) can have non-additive effects on plant fitness. This is often interpreted as evidence for correlated evolution on a suite of traits leading to ...

Orellana, José I.; Smith Ramírez, Cecilia; Rau, Jaime R.; Sade, Soraya; Gantz, Alberto; Valdivia, Carlos E. (Springer, 2014)BACKGROUND: Frugivorous birds are phenologically linked to the fruits that they eat. When there is less fruit in seasonal environments, frugivorous birds complement their diet by eating invertebrates. The depth of the ...

Valdivia, Carlos E.; Cisternas, Mauricio A.; Verdugo, Gabriela S. (EDICIONES UNIV, CONCEPCION, COMITE DE PUBLICACION, 2010-01-11)The extent to which plants depend on pollinators for outcross pollen transportation is a key issue in plant reproductive ecology. We evaluated the putative breeding system, floral display, and natural pollination in two ...

Valdivia, Carlos E.; González Gómez, Paulina L. (GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2006-05)Nectar thieves may increase or decrease pollinator-mediated pollen flow and thus may have positive or negative effects on plant reproductive success. In temperate rainforests of South America, the hummingbird Sephanoides ...
