Siparuna guianensis is a neotropical tree species, found both on edge and interior of forest fragments, mainly on understory and regeneration areas. The fruit are zoochorous with a sweet aril. This work aims to determine the bird species that eat the fruits of S. guianensis in a semi deciduous forest fragment in Brazilian Cerrado and measure which species have the highest potential as seed dispersers. Seven individuals of S. guianensis were sampled, totaling 69 hours. A hundred and fifty four visits were registered by seven species of birds. Antilophia galeata had the biggest potential as seed dispersal agent. Antilophia galeata, Lanio penicillatus and Dacnis cayana can be important seed dispersers, since they have a high consumption and visitation rate. The consumption of S. guianensis by species of different feeding guilds can be an important strategy for dispersal of plant species in regeneration habitats, raising the chances of an effective dispersal.

OBJECTIVES: To identify rubella prevalence in different ages and population groups and rubella susceptibility of pregnant and postpartum women according to age, number of children and spontaneous abortion. METHODS: Cross-sectional study of sero-survey type. Children and students were selected in day-care centers and schools distributed by health districts of Fortaleza. Pregnant and postpartum healthy women were recruited in two large maternity units and three antenatal clinics; individuals previously vaccinated and presenting chronic or acute diseases where excluded. Written consent was obtained from participants or their caretakers. Anti-rubella IgG qualitative detection was performed with an Elisa-sandwich assay. RESULTS: Mean age-specific sero-prevalence rates of 999 samples were: 2 to 5 years= 59% (136/231); 6 to 9 years= 47% (95/204); 10 to 19 years= 56% (243/432) and 20 to 39 years= 80% (106/132). The mean age of 187 pregnant and postpartum women was 23 years (10-39) with a sero-prevalence of 76% (142/187), where 62% sero-positives aged 15 to 19 and 83% aged 26 to 39 years. A higher sero-prevalence was related to womens age (p
