ABSTRACT
Mangroves are transitional ecosystems between terrestrial and marine environments, and are distinguished by a high abundance of animals, plants, and fungi. Although macrofungi occur in different types of habitat, including mangroves, little is known about their community structure and dynamic. Therefore the aim of this study was to analyze the diversity of macrofungi in a number of Brazilian mangroves, and the relationship between such diversity, precipitation and area of collection. A total of 32 field trips were undertaken from 2009 to 2010, and macrofungi were studied in four 250×40m transects Timbó and Santa Cruz Channel on the Northern coast, and Maracaípe and Ariquindá on the Southern coast. All basidiomata found along the transects were placed in paper bags, air-dried and identified using existing literature. It was found that Northern areas predominantly featured Avicennia schaueriana mangroves, while Rhizophora mangle dominated in Southern transects. A total of 275 specimens were collected, and 33 species, 28 genera, 14 families and six orders were represented. Overall abundance and species richness did not vary significantly among areas, but varied according to time, being higher during the rainy season. Subtle differences in composition were observed over time and between areas, probably due to variations in plant species occurrence. Further studies with collections during months of greater precipitation in transects dominated by different mangrove species of the same ecosystem are suggested to assess the overall diversity of mycobiota in these ecosystems.
RESUMEN
Los manglares son ecosistemas de transición entre los ambientes terrestres y marinos, y se distinguen por la gran abundancia de animales, plantas y hongos. Aunque los macrohongos se encuentran en diferentes tipos de hábitat, incluidos los manglares, poco se sabe acerca de la estructura de su comunidad y dinámica. Por lo tanto, el objetivo de este estudio fue analizar la diversidad de macrohongos en los manglares de Brasil y su relación con la precipitación y área de recolección. Se realizaron un total de 32 salidas de campo entre 2009 y 2010, y los macrohongos fueron estudiados en cuatro transectos de 250×40m Timbó y Canal de Santa Cruz en la costa norte y Maracaípe y Ariquindá en la costa sur. Todos los basidiomas encontrados a lo largo de los transectos se colocaron deshidratados en bolsas de papel, y se identificaron con ayuda de la literatura preexistente. Se encontró que las zonas del norte predominantemente presentaron Avicennia schaueriana, mientras Rhizophora mangle domina en transectos del sur. Se recolectaron un total de 275 especímenes y 33 especies, 28 géneros, 14 familias y seis órdenes estuvieron representados. Abundancia y riqueza de especies en general no varió significativamente entre las áreas, pero si varió en el tiempo, siendo mayor durante la estación lluviosa. Se observaron diferencias sutiles en la composición a través del tiempo y entre áreas, probablemente debido a las variaciones en la presencia de las especies de plantas. Otros estudios con recolectas durante los meses de mayor precipitación en transectos dominados por diferentes plan- tas de manglar en el mismo ecosistema son deseables para acceder a la diversidad de la micobiota.
