Niphargus occurrence in relation to the standardized bio-area of other macroinvertebrates. Predictions of binomial GLM are plotted as solid line with 95% confidence interval (shaded area). The binomial GLM was fitted to 334 sites with bio-area < 40,000 mm2/100 ML discharged groundwater. Bio-area in mm2 per 100 ML discharged groundwater.
