Resumen
Se presentan aspectos generales sobre la polinización de bromelias epifitas en los bosques neotropicales de montaña, a partir de una revisión de temas que involucran desde la biología floral y los síndromes de polinización hasta las interacciones a nivel comunitario con sus grupos de polinizadores, haciendo énfasis en la polinización ornitofila, la cual generalmente es realizada por colibríes, y algunos aspectos evolutivos en las interacciones bromelia-colibrí. Finalmente se hacen algunas consideraciones en cuanto a la influencia humana sobre las interacciones a nivel comunitario y se destacan algunas perspectivas y necesidades futuras de investigación.
