Background Gynodioecy is a reproductive system of interest for evolutionary biologists, as it
poses the question of how females can be maintained while competing with hermaphrodites …

Latitudinal gradients in biotic interactions have been suggested as causes of global patterns
of biodiversity and phenotypic variation. Plant biologists have long speculated that …

Background and Aims About 6% of an estimated total of 240 000 species of angiosperms
are dioecious. The main precursors of this sexual system are thought to be monoecy and …

Abstract Background and Aims Few studies have examined the dynamics of specialist plant–
pollinator interactions at a geographical scale. This knowledge is crucial for a more general …

Background and Aims Reproductive character displacement (RCD) is often an important
signature of reinforcement when partially cross-compatible taxa meet in secondary …

Abstract Background and Aims: Clonality is characterized by the formation of independent
individuals of the same genotype that are capable of reproducing and propagating …

Populations of widely distributed plants may experience varying climatic or ecological
conditions, leading to uneven evolution of reproductive traits. However, studies on …

In Cerrado humid areas, veredas are considered as hygrophilous communities, with an
herbaceous/shrub stratum in open areas and an arboreal stratum in forest areas. We …

Heat and odour production can have profound effects on pollination in cycads. It is therefore
expected that these traits would co‐vary geographically with pollinator assemblages. Such …

Floral biology and breeding system of Bauhinia forficata (Leguminosae: Caesalpinioideae),
a moth-pollinated tree in southeastern Brazil. Bauhinia trees have a wide variety of …
