No. of bitstreams: 1 45-mara-rubia-dissertacao-completa-21-03-2013.pdf: 2507364 bytes, checksum: ff7d2243b7ca90f0ef456fa17718207d (MD5) Previous issue date: 2013-03-21 === Was conducted a study of reproductive phenology of three species of Miconia Ruiz & Pav. (Melastomataceae) occurring in the gallery forest Len??is river, in Len??is Municipality (12 ? 27'30 "S and 41 ? 27'56" W), Chapada Diamantina, discussing reproductive strategies found in sympatric species with similar morphology of flowers and fruits. The phenological observations were made monthly for 48 months in individuals of the species Miconia alborufescens Naud.,Miconia holosericea (L.) DC. and Miconia prasina (Sw) DC., being accompanied phenophases bud, flower, immature fruit and ripe fruits. The species exhibited a pattern reproductive annual, seasonal, sequential, varying its duration. The offer of flowers occurred typically the beginning of the rainy season and no overlap between species. The offer of fruits occurred since the mid rainy season and the dry season without overlapping. The circular statistical tests indicated strong seasonality of fenofases. The irregularity of rainfall and prolonged drought occurred in the last year of observation influence at the time of the manifestation of reproductive phenology M. holosericea and M. prasina, but they fit for the supply of the resource was not superimposed, favoring the maintenance of pollinators and dispersers to these associates. === Foi realizado um estudo da fenologia reprodutiva de tr?s esp?cies de Miconia Ruiz & Pav. (Melastomataceae) ocorrentes na floresta ciliar do rio Len??is, no Munic?pio de Len??is (12?27?30?S e 41?27?56?W), Chapada Diamantina, Bahia, Brasil, discutindo as estrat?gias reprodutivas encontradas em esp?cies simp?tricas com morfologia similar de flores e frutos. As observa??es fenol?gicas foram realizadas mensalmente por 48 meses em indiv?duos das esp?cies Miconia alborufescens Naud., Miconia holosericea (L.) DC. e Miconia prasina (Sw) DC., sendo acompanhadas as fenofases de bot?o, flor, fruto imaturo e fruto maduro. As esp?cies exibiram um padr?o reprodutivo anual, sazonal, sequencial, com dura??o variada. A oferta de flores ocorreu tipicamente no in?cio da esta??o chuvosa e sem sobreposi??o entre as esp?cies. A oferta de frutos ocorreu desde a esta??o chuvosa at? meados da esta??o seca e sem sobreposi??o. Os testes de estat?stica circular indicaram forte sazonalidade das fenofases.A irregularidade da precipita??o e a estiagem prolongada ocorrida no ?ltimo na o de observa??o influenciou a fenologia reprodutiva de M. holosericea e M. prasina, por?m as mesmas ajustaram-se fenologicamente para que a oferta do recurso n?o fosse sobreposta, favorecendo a manuten??o da fauna de polinizadores e dispersores a estas associadas.
