Nectar ecology of the endemic epiphytic hummingbird-pollinated bromeliad Vriesea altodaserrae: secretion dynamics and pollinator visitation pattern

Acta Botânica Brasílica, 2018
Hummingbirds are the main pollinators of most bromeliad species, whose nectar traits usually respond to the selective pressures imposed by pollinators.

The link between colorfulness and extinction risk across the world's passerine birds

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Many of the functional traits that mediate extinction risk across the range of biodiversity relate indirectly to a species’ ability to persist in a changing world, yet certain traits such as coloration directly affect human interactions with wildlife.

Hummingbirds in high alpine habitats of the tropical Mexican mountains: new elevational records and ecological considerations

Avian Conservation and Ecology, 2018
Most hummingbird species are distributed in tropical lowlands and mountains with few species reaching the alpine environments of high mountain peaks. Field surveys were conducted in nine alpine sites across four of the highest volcanoes in central Mexico

Specialization in plant-hummingbird networks is associated with species richness, contemporary precipitation and Quaternary climate-change velocity [PDF]

, 2011
Large-scale geographical patterns of biotic specialization and the underlying drivers are poorly understood, but it is widely believed that climate plays an important role in determining specialization.

The rate of visitation by Amazilia fimbriata (Apodiformes: Trochilidae) influences seed production in Tillandsia stricta (Bromeliaceae)

Zoologia (Curitiba), 2015
Legitimate flowers visitors pollinate the flower during the visit and thus influence the production of fruits and seeds. We tested whether the visitation rate of potential pollinators is associated with the amount of seeds per fruit produced by the self ...
