Reproductive biology of six Brazilian Myrtaceae: is there a syndrome associated with buzz-pollination?
(RSNZ PUBLISHING, 2009)
The floral phenology and reproductive biology of six sympatric arboreal Myrtaceae species were studied in the coastal plain forest (Ubatuba, Brazil, 44 degrees 48`W 23 degrees 22`S), from September 1999 to April 2002. ...
The predictive power of pollination syndromes: Passerine pollination in heterantherous Meriania macrophylla (Benth.) Triana (Melastomataceae)
The cloud forest species Meriania macrophylla (Benth.) Triana has pseudocampanu- late flowers with bulbous stamen appendages, typical for the passerine pollination syndrome found in the Melastomataceae tribe Merianieae. ...
Pollen diet assessment and flower association in Melipona orbignyi and recommendations on management and conservation of stingless bees in the Chaco dry forest of South America
Management and conservation of wild pollinators in forests of the Chaco region of South America is of great interest nowadays as they are pollen vectors that improve the reproductive success of many forest species which ...
Crepuscular pollination and reproductive ecology of Trembleya laniflora (Melastomataceae), an endemic species in mountain rupestrian grasslands
The “pollination syndrome” hypothesis predicts a direct relationship between a set of floral characters and the principal pollinating agent. The presence of flowers with poricidal anthers, heterostemony and pollen as the ...
