The chironomid Benthic Quality Index (BQI) is a widely used metric in assessments of lake status. The
BQI is based on 7 indicator taxa, which like most profundal fauna, often occur sporadically in low densities.
Hence, a major weakness of the index is that it cannot be calculated when indicator taxa are not captured. Thus,
an extension of the BQI that incorporates more macroinvertebrate taxa is desirable. We used 2 statistical
approaches (Detrended Correspondence Analysis and Weighted Averaging) to estimate new benthic quality
indicator scores for profundal macroinvertebrate taxa and to construct modified BQIs called Profundal Invertebrate
Community Metrics (PICMs). We calibrated the PICMs and evaluated their bioassessment performance
with macroinvertebrate and environmental data from 735 lake basins in Finland. Both PICMs included 70 taxa
and could be calculated for a substantially greater proportion (99.5%) of sites than the original BQI (83.5%).
Compared to the BQI, the PICMs were more strongly correlated with whole-community variation and were
more predictable from environmental factors independent of human activities in undisturbed reference lakes.
PICMs were more specific in identifying undisturbed lakes and more sensitive in discriminating nonreference
from reference lakes. The strength of relationships to total P concentration was equal among indices. These
results suggest that the extension of BQI to incorporate more taxa will increase generality, accuracy, and representativeness
of lake profundal macroinvertebrate assessment.
