| Sumario: | Brazilian semi-arid region includes territorial areas of eight states, from Northeast to Minas Gerais North, presenting two well-defined seasons during the year, a rainy season (December to April), and a dry one (May to November). During the short rainy season, temporary ponds are formed which are ecosystems that shelter a very peculiar macrophyte flora adapted to the high light incidence and seasonal rainfall in this region. Associated to this aquatic flora, there is a rich periphytic community, which includes, for example, bacteria, fungi, small metazoans, and especially a wide diversity of microalgae and cyanobacteria. In this context, the present work was carried out in order to characterize the periphytic phycoflora associated to aquatic macrophytes of temporary ponds in the Bahia semi-arid region. Sampling was performed in six temporary ponds located along the highway BA-052 (Estrada do Feijão), along July and September 2013. Seven macrophytes species and 43 periphytic taxa of microalgae and cyanobacteria were identified. This pioneering study contributes to filling the gaps in knowledge about the periphyton of temporary ponds, showing that, although they are ephemeral due to the rainfall seasonal pattern, they harbor an important diversity of macrophytes as well as a rich phycoflora. These primary producers are essential for the functioning of these temporary habitats, providing ecosystem services for human populations, as well as contributing to the biodiversity of semi-arid regions. |
