Melittophily and Ornithophily of Long-tubed Flowers in Zingiberaceae and Gesneriaceae in West Sumatra

Melittophily and Ornithophily of Long-tubed Flowers in Zingiberaceae and Gesneriaceae in West Sumatra, 1993
Pollination of seven zingiberaceous and two gesneriaceous species was studied in natural forests at various altitudes in West Sumatra, Indonesia. Terrestrial, red, long-tubed flowers of Achasma macrocheilos were visited by a large, remarkably long-tongued anthophorine bee, Amegilla elephas.

How are pollination and seed dispersal modes in Cerrado related to stratification? Trends in a cerrado sensu stricto woodland in southeastern Brazil, and a comparison with Neotropical forests

Acta Botânica Brasílica, 2018
A comprehensive census of a hectare of cerrado s.s. in southeastern Brazil, a small-tree and scrub woodland physiognomy, allowed the evaluation of whether pollination and dispersal modes are correlated with the stratification of the vegetation and if so,

BEYOND HUMMINGBIRD-FLOWERS: THE OTHER SIDE OF ORNITHOPHILY IN THE NEOTROPICS

Oecologia Australis, 2010
Polinizacao por aves na regiao Neotropical e amplamente conhecida como uma importante interacao ecossistemica, mas as aves que pousam e que visitam flores sao ainda vistas como meras oportunistas. Apesar dessas outras aves nao dependerem somente de recursos florais, existem muitas plantas que dependem exclusivamente delas para a sua polinizacao.
