Habitat and Ecology [top]

Habitat and Ecology: D. singularis is a benthopelagic (ecological region at the lowest level of water body) species. Small rivers, clear water fast flowing rock bottom. Feeds on insects and other small invertebrates and graze on plant matter, grazing on it on rocks.
Systems: Freshwater

Threats [top]

Major Threat(s): D. singularis may be threatened with habitat degradation in some parts of its range, as wetlands in Santa Catarina are impacted from activities connected with coal production (Diegues 1994). For many years coal mining was the largest productive activity in southern Santa Catarina. In the past, coal mining was executed with little environmental care and was the principal cause of water pollution in the region. The improper management of residues generated by the exploration and processing of coal, in some cases still practiced today, has resulted in acid mine drainage which has contaminated water and soil with sulphuric acid and toxic metals. The consequences of this pollution are still found in the regional environment (SIECESC 2004). Although a restricted species, D. singularis is unlikely to be under threat by these processes throughout its entire range, or with great severity.
