Floristic composition and dispersal syndromes at an urban remnant from the Atlantic forest in Brazilian Northeast = Composição florística e síndromes de dispersão em um fragmento urbano da Mata Atlântica do Nordeste Oriental, Brasil

Floristic composition and dispersal syndromes were determined along one year in an open ombrophilous forest fragment in the Municipal Park of Maceió, Alagoas State, Brazil. A total of 178 species belonging to 61 families were examined. Fabaceae was the most species-rich family, with 24 species. Amon...

Description
Summary:Floristic composition and dispersal syndromes were determined along one year in an open ombrophilous forest fragment in the Municipal Park of Maceió, Alagoas State, Brazil. A total of 178 species belonging to 61 families were examined. Fabaceae was the most species-rich family, with 24 species. Among sampled species, 123 had their syndromes of diaspore dispersal determined, and most of them (69%) were zoochoric. Anemochoric and autochoric plants represent 11 and 20% from the total, respectively. The data about reproductive phases indicate coincident peaks of flowering and fruiting in August, at the end of the rainy season. The results are in accordance to those expected for ombrophilous forest with poorly defined seasonality. <br><br>A composição florística e as síndromes de dispersão foram determinadas no presente estudo, ao longo de um ano, em um fragmento de floresta ombrófila aberta no Parque Municipal de Maceió, Estado daAlagoas. Foram amostradas 178 espécies, pertencentes a 61 famílias. Fabaceae foi a família de maior riqueza florística, com 24 espécies. Das espécies coletadas, 123 tiveram sua síndrome determinada e a maioria delas (69%) é zoocórica. As plantas anemocóricas e autocóricas representam 11 e 20%, respectivamente. Os dados sobre a fase reprodutiva apontam um pico de floração e de frutificação coincidente, no mês de agosto, no final da estação chuvosa. Os resultados encontrados estão de acordo com o esperado para florestasombrófilas de sazonalidade pouco evidente.
