Description
Summary:The reproductive phenology and guild of the floral visitors of Canistropsis microps in an Atlantic Forest area in Ilha Grande, RJ were studied for 4 years. The rates of flowering, fruiting and mortality were related to air temperature, rainfall and photoperiod. To register the flower visitors, observations were carried out for 5 days in each reproductive season. The flowering and fruiting occurred in the rainy season and were positively related to the studied climatic variables, whereas the highest mortality rates occurred in the dry season and were negatively related to the climatic variables. The guild of floral visitors of C. microps was composed of Hymenoptera, characterizing the species as a melittophilous plant. These results indicate that the rainy season presents more favourable conditions for investment in sexual reproduction, besides being the period in which potential pollinators have larger population densities and a longer period of activity.
