As primeiras sementes maduras surgiram em maio de 1989, caindo no chão até agosto. A produção estimada de 25 kg/ha de sementes não provocou aumentos populacionais entre os roedores presentes na área. Entre as aves apenas Haplospiza unicolor demonstrou alguma associação com o bambu, sendo provavelmente um especialista em sementes de bambu. C. meyeriana evitaria a predação de sementes "ocultando" suas pequenas sementes entre as muito mais abundantes flores e sementes abortdas. ...Observação: O resumo, na íntegra, poderá ser visualizado no texto completo da tese digital / Abstract: Chusquea meyeriana, a bamboo endemic to the Atlantic Forest, mast-flowered at Fazenda Intervales, southern São Paulo, at the end of 1988. The first mature seeds began to fall on the ground by May, 1989. The estimated production of 25 Kg/ha of seeds had no obvious effect on the rodent populations in the area. Amongst the birds, only Haplospiza unicolor showed any association with the bamboo, being probably a bamboo-seed specialist. Contrary to other bamboos, C. meyeriana appear to minimize seed predation by "hiding" its small seeds among much more abundant aborted flowers and seeds. ¿Note: The complete abstract is available with the full electronic digital thesis or dissertations / Mestrado / Ecologia / Mestre em Ciências Biológicas
