Abstract
Desmids are one of the most representative groups of algae in oligo-mesotrophic aquatic environments. They respond to environmental changes and can be used as indicators of water quality. We evaluated changes in the structure of desmid communities on emergent macrophytes in relation to environmental conditions at a spatial scale in two rivers in a tropical urban basin in the State of Bahia, Brazil. Sampling was carried out every two months for one year at five fixed stations. Changes in the desmid community structure were associated with variations in limnological conditions, which differed between the sampling stations. We observed increases in total phosphorus concentration and conductivity from upstream to downstream, which influenced the changes in desmid community structure. Desmid richness and total density were higher in urban, recreational, and more preserved areas. In conclusion, phosphorus availability associated with land use and urbanization influenced desmid community structure variability in coastal plain rivers.
期刊介绍:
Aquatic Ecology publishes timely, peer-reviewed original papers relating to the ecology of fresh, brackish, estuarine and marine environments. Papers on fundamental and applied novel research in both the field and the laboratory, including descriptive or experimental studies, will be included in the journal. Preference will be given to studies that address timely and current topics and are integrative and critical in approach. We discourage papers that describe presence and abundance of aquatic biota in local habitats as well as papers that are pure systematic.
The journal provides a forum for the aquatic ecologist - limnologist and oceanologist alike- to discuss ecological issues related to processes and structures at different integration levels from individuals to populations, to communities and entire ecosystems.
