Premise There is little direct evidence linking floral development and pollination biology in plants. We characterize both aspects in plain and ornamented flowers of Trimezieae (Iridaceae) to investigate how changes in ...

Oil-flower species are highly specialized attracting a narrow group of oil-collecting bees in contrast to nectar-flower species visited by a wide diversity of pollinators. The vast majority of the oil species lack nectar ...

Background and Aims: The underlying evolutionary processes of pollinator-driven floral diversification are still poorly understood. According to Grant-Stebbins model speciation begins with adaptive local differentiation ...

Gomesa bifolia (Orchidaceae, Cymbidieae, Oncidiinae) es una orquídea epífita que presenta vistosas flores amarillas con marcas marrones en los sépalos y pétalos, carentes de fragancia y con aceite como recompensa. La ...

In tropical savannas, such as the campo cerrado in Brazil, fire plays an important role, affecting plant species’ life history. Since fire has the potential to modify the structure of savanna communities as a whole, it is ...

Pollination is one of the most important ecosystem services for maintaining biodiversity, as it is a key process for restoring the function of altered ecosystems. It is largely carried out by bees both in agricultural and ...

Plants have many different microhabitats favorable to the growth of yeasts, such as flowers, fruits, sap and decomposing tissues. However, most yeasts that colonize these microenvironments depends on insects toward dispersal. ...

Bees of the genus Chalepogenus Holmberg collect oils offered as a reward by flowers of a few plant families: Iridaceae, Calceolariaceae (formerly included in Scrophulariaceae, see Olmstead et al. 2001), and Solanaceae ...
