1. Efeito de vespas galhadoras (Hymenoptera: Chalcidoidea) na duração da receptividade floral de Ficus citrifolia (Moraceae) / Galler wasps (Hymenoptera, Chalcidoidea) effect on th length of floral receptivity of Ficus citrifolia (Moraceae)
The breeding success of Ficus trees and the maintenance of their mutualistic fig wasps depend on the successful pollination of pistilate flowers (seed production) and on the development of pollinating wasps in some galled ovaries (production of pollen vectors). The period during which pistilate flowers are receptive for pollination and oviposition is short c

2. PolinizaÃÃo de Tabebuia Impetiginosa e Jacaranda Rugosa (Bignoniaceae) e o efeito de Pilhadores no seu sucesso reprodutivo no Parque Nacional do Catimbau
studied in the National Park of Catimbau, emphasizing the activity of nectar robbers on their reproductive success. The mechanism of stigma closure was also investigated in these and in other three species of this family, Anemopaegma laeve, Arrabidaea limae and Jacaranda irwinii. T. impetiginosa and J. rugosa are self-incompatible species and depends on medi

3. Resolution of male-female conflict in an hermaphroditic flower.
The flowers of most angiosperm species are hermaphroditic. Spatial separation of male and female organs within a flower (hercogamy) is a common character traditionally interpreted as an adaptation to reduce intrafloral self-fertilization, one potential cost of hermaphroditism. Another possible cost that may lead to selection for hercogamy is physical interfe
