Aquatic macroinvertebrates and relationship with leaf litter decomposition of three palms species in a neotropical stream.
Macroinvertebrates are important in autochthonous litter decomposition in aquatic ecosystems. In this study, aquatic macroinvertebrates colonization in a litter decomposition process of three Arecaceae family species was evaluated. Litter packet methodology was used, macroinvertebrate assembly, litter decomposition rates, and chemical characteristics of each plant species was evaluated. The greatest loss of plant biomass was recorded in Elaeis guineensis, followed by Mauritia flexuosa and Attalea butyracea litter. Reduced presence of associated macroinvertebrates in the three palm species was observed. Scrapers and collector-gatherers were the dominant functional food groups. Our results show the importance of litter chemical characteristic in detritivores activity, suggest its relevance in the organization that macroinvertebrates found in spatial and temporal scales.
