Station B showed disturbance (polluted condition), hence the curve for abundance lied above biomass with a wide
margin (Figure 4). Station C showed disturbance, hence the curve for abundance lied above the biomass curve.
The margin indicating the extent of pollution was however not as wide as that in station B (Figure 5). Station D
showed relatively polluted condition. Hence, the curve for biomass overlapped the abundance curve with a narrow
range (Figure 6).
