Meta-analysis of meta-analyses in plant evolutionary

Description: 10 páginas, 1 figura, 1 tabla. , After two decades of meta-analyses on plant traits, we can now look for global emergent patterns in plant evolutionary ecology. Hundreds of meta-analyses have focused on the effects of specific selection pressures on plant fitness, and the buildup of such results allows...

Phenology, seed dispersal and difficulties in natural recruitment

Description: 13 páginas, 5 figuras, 2 tablas. , commercial species. This study focused on a widely exploited Neotropical canopy species, Pachira quinata (Malvaceae), at the southernmost, wettest limit of its natural distribution, in the Colombian Amazonia. We studied phenological patterns, seed production and natur...

Patterns of plant species richness within families and genera in lowland neotropical forests: Are similarities related to ecological factors or to chance?

Description: 22 páginas, 3 figuras, 3 tablas. , We compared information on 26 lowland Neotropical florulas, in order to assess which processes are correlated with the patterns of floristic similarities, based on plant species richness within families and genera. The results at the family level indicated that floris...

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...

Field heritability of a plant adaptation to fire in heterogeneous landscapes

Description: The strong association observed between fire regimes and variation in plant adaptations to fire suggests a rapid response to fire as an agent of selection. It also suggests that fire-related traits are heritable, a precondition for evolutionary change. One example is serotiny, the accumulation of se...

Fires can benefit plants by disrupting antagonistic interactions

Description: Fire has a key role in the ecology and evolution of many ecosystems, yet its effects on plant–insect interactions are poorly understood. Because interacting species are likely to respond to fire differently, disruptions of the interactions are expected. We hypothesized that plants that regenerate af...
