Spatial and temporal heterogeneity in lotic systems : implications for defining reference conditions for macroinvertebrates

Spatial and temporal heterogeneity of lotic systems was examined by assessing variability in macroinbertebrate assemblages in two geographic regions, the Western Cape and Mpumalanga, in South Africa. Assemblages were assessed using the South African Scoring System (SASS), a rapid bioassessment method. The implication of spatial variability at regional, subregional and habitat levels, and temporal variability for defining reference conditions for macroinvertebrates was evaluated.
