文摘
- •
Benthic macroinvertebrates in 12 streams were sampled up to 14 times over 19 months.
- •
Community structure was altered in streams with elevated specific conductance (SC).
- •
Aggregate metrics include tolerant taxa, can mask SC effects and seasonal variation.
- •
Metrics differed among months: timing of sampling is important for bioassessment.
- •
Moderate SC elevation may increase macroinvertebrate community temporal variability.
