Daftar Isi:
- The objectives of this research were to record the changes in composition of the community of Ephemeroptera in Plalar - Gremeng River, Gunung Sewu, Gunungkidul, to examine the causes of these changes, and to discover their significance in the life of the rivers. The ephemeropteran community and abundance of the feeding group (detritivore, gatherer, and scrapper) was compared with the nutrient and water quality of each sampling site in the rivers. It is established that, under site conditions, nutrient status can be regarded as the chief internal factors. The method was field survey for sampling the substrate at five sites: 1. Up stream of Plalar River; 2 . The site before the Plalar Cave; 3. The total dark zone of Plalar – Gremeng Caves; 4 . The site after Gremeng Cave; and 5. The down - stream of Gremeng to Be ton River. Substrate sampling used Surber benthic sampler (25 x 25 cm) , the sample was containing and labeling. Environmental parameters were measured water temperature; carbon dioxide; velocity; pH; C-organic; P and N substrate; and Ca content. The data was analyzed by description. There sults were showed the abundance of Ephemeroptera highest at sit e-4 (Gremeng River) and the low estat site - 3 (in the dark zone of the cave). The zonation studies showed that Ephemeropthera play a highly important roles in preserving nutrient status. Ephemeropthera are dominates a sub system that retard nutrient dynamic, water quality degradation, and thus they play a prominent role in the karst water bodies.
