Resumo: | Many Ficus species play an important role as food resources for tropical forest fauna. This suggests that the genus has potential for use in restoration projects on degraded land. Phenological monitoring of these species may also suggest management strategies for conservation areas. Individuals of F. guaranitica were monitored weekly on the campus of Londrina State University for 22 months. Phenological parameters observed were: onset of flowering, total number of fruiting trees, and the duration of fruiting and leaf production. The parameters were compared to some climatic variables (maximum, minimum, and average temperature; relative air humidity; insolation; solar radiation; and rainfall). Fruiting trees were observed throughout the study period, but a higher percentage of individuals fruited during the coldest period of the year. Flowering onset occurred year-round with no significant seasonality. In winter, an extension of the fruiting period and a higher percentage of trees losing leaves were observed. Due to this year-round phenology F, guaranitica has a high potential as a food source for fauna in degraded habitats. This suggests that it can be a "keystone species" in conservation areas. |

Muitas espécies de Ficus desempenham um importante papel como fonte de recursos alimentares para a fauna silvestre, tendo, portanto, potencial de utilização em projetos de recuperação de ambientes degradados. Desta forma o estudo da fenologia de espécies de Ficus permitirá estabelecer estratégias para o seu manejo em unidades de conservação. Com o objetivo de conhecer o potencial de F. guaranitica, como fonte de recursos alimentares para a fauna em ambientes alterados, foram monitoradas semanalmente indivíduos de F. guaranitica do campus da Universidade Estadual de Londrina durante um período de 22 meses. Os parâmetros fenológicos observados foram: início de florescimento, total de árvores frutificando, duração da frutificação e quantidade de folhas. Estes parâmetros foram comparados com algumas variáveis climáticas (temperatura máxima, mínima e média; umidade relativa do ar; insolação; radiação solar e precipitação pluviométrica). Observaram-se árvores frutificando em todo o período de estudo, porém com maior porcentagem de indivíduos frutificando nos períodos mais frios do ano. Os inícios de florescimento ocorreram ao longo de todo o ano, porém sem aparente sazonalidade. No inverno observou-se um prolongamento na duração da frutificação e maior porcentagem de árvores perdendo folhas. Devido ao seu comportamento fenológico, F. guaranitica, mostra grande potencial como fonte de recursos alimentares para a fauna em ambientes degradados. Este hábito também coloca a espécie no grupo de "espécies-chave" de unidades de conservação.
