    Seasonality of Leaf and Fig Production in Ficus squamosa, a Fig Tree with Seeds Dispersed by Water

    The phenology of plants reflects selection generated by seasonal climatic factors and interactions with other plants and animals, within constraints imposed by their phylogenetic history. Fig trees (Ficus) need to produce figs year-round to support their short-lived fig wasp pollinators, but this requirement is partially de-coupled in dioecious species, where female trees only develop seeds, not pollinator offspring. This allows female trees to concentrate seed production at more favorable times of the year. Ficus squamosa is a riparian species whose dispersal is mainly by water, rather than animals. Seeds can float and travel in long distances. We recorded the leaf and reproductive phenology of 174 individuals for three years in Chiang Mai, Northern Thailand. New leaves were produced throughout the year. Fig production occurred year-round, but with large seasonal variations that correlated with temperature and rainfall. Female and male trees initiated maximal fig crops at different times, with production in female trees confined mainly to the rainy season and male figs concentrating fig production in the preceding months, but also often bearing figs continually. Ficus squamosa concentrates seed production by female plants at times when water levels are high, favouring dispersal by water, and asynchronous flowering within male trees allow fig wasps to cycle there, providing them with potential benefits by maintaining pollinators for times when female figs become available to pollinate

    The aim of this study was to know and understand the representations and use of medicinal plants by elderly men assisted in the Family Health Strategies of Dourados, MS. Participated in this study, 18 elderly men aged over 60 years, using four or more medications. The research was conducted with qualitative approach. The results showed that there is still the consumption of medicinal plants among the elderly, especially in the treatment of minor harm. The representations about the plants seem anchored in the concept of safety; they are natural and few side effects. Its use is made concurrently with the manufactured medicines without regard to risk of interactions. Older men use medicinal plants, without however reporting to health professionals. Therefore, it is necessary continuing education focused on phytotherapy health team and nursing, contributing to safe and effective use of medicinal plants.El objetivo de este estudio fue conocer y comprender las representaciones y el uso de plantas medicinales por los mayores asistidos en Estrategias de Salud de la Familia de Dourados/MS. Participaron de ese estudio 18 hombres de edad con edad igual o superior a 60 años, haciendo uso de cuatro o más medicamentos. Se trató de investigación cualitativa, descriptiva y exploratoria. Los resultados apuntaron que aun existe el consumo de plantas medicinales entre los mayores, principalmente en el tratamiento de mortalidades menores. Las representaciones sobre las plantas medicinales parecen ancladas en la concepción de seguridad, o sea, son naturales y pocos efectos colaterales. Su uso es hecho concomitantemente con los medicamentos industrializados, sin atentar los riesgos de las interacciones. Los mayores utilizan las plantas medicinales sin, sin embargo, relatar a los profesionales de salud. Luego, se hace necesario la educación permanente del equipo de salud y de la enfermería vuelta para la fitoterapia, aportando al uso seguro y eficaz de las plantas medicinales.Objetivou-se, neste estudo, conhecer e compreender as representações sobre o uso de plantas medicinais por homens idosos, assistidos em Estratégias de Saúde da Família de Dourados, MS.

Os resultados apontaram que ainda existe o consumo de plantas medicinais entre os idosos, principalmente no tratamento de morbidades menores. As representações sobre as plantas medicinais parecem ancoradas na concepção de segurança, ou seja, são naturais e apresentam poucos efeitos colaterais. Seu uso é feito concomitantemente com os medicamentos industrializados, sem atentar para os riscos das interações. Os homens idosos utilizam as plantas medicinais sem, no entanto, relatar aos profissionais de saúde. Logo, faz-se necessária a educação permanente da equipe de saúde e da enfermagem, voltada para a fitoterapia, visando contribuir para o uso seguro e eficaz das plantas medicinais
