How barriers to gene flow arise and are maintained are key questions in evolutionary
biology. Speciation research has mainly focused on barriers that occur either before mating …

This study characterizes the osmophores and corolla traits in 18 species of Bignonieae
Dumort., a Bignoniaceae tribe occurring in the Cerrado, a neotropical savanna in Brazil. To …

The floral traits in Bignoniaceae are claimed as precise determiners of specialized
pollination systems. Here, we investigated how such floral traits ensure a highly specialized …

Abstract Although orchid bees (Apidae: Euglossini) are known as key pollinators in tropical
ecosystems, knowledge of their floral sources is still scarce, especially for those species …

Late-acting self-incompatibility (LSI) has been defined as a genetically controlled self-
sterility mechanism that prevents seed set by selfing, despite normal pollen tube growth and …

Pollination plays a vital role in maintaining ecological functioning of ecosystems, and bees
are the main pollinating insects in natural and agricultural areas. Identification of bee food …

Sunnhemp (Crotalaria juncea), is a commercially important bast fibre crop that possesses
late-acting self-incompatibility. Crops with hermaphrodite flowers expressing late-acting self …

Bees are the main pollinators of terrestrial ecosystems and, among them, we can highlight
oil-collecting bees, which show different morphological and behavioral adaptations …

Mixed cross and self‐pollen load on the stigma (mixed pollination) of species with late‐
acting self‐incompatibility system (LSI) can lead to self‐fertilized seed production. This …

Phenological events and floral biology of Jacaranda ulei were studied. After the first rains,
new branches, leaves and flowers are produced. The flowering period lasts for almost three …
