Abstract

Statement of the Problem: In Nigeria, there have been increasing alarms on pollution loads in freshwater ecosystem. Methodology & Theoretical Orientation: Macroinvertebrate biological traits were used to assess the impact of pollution in River Chanchaga. Selected biological traits were used in this study. Fuzzing coding system was employed to describe the link between a taxon and each trait classes with affinity scores that account for potential functional variation between members of the same family. Findings: From the fuzzy coding system analysis; body size class A5 (>40-80 mm) dominated stations 1 and 2 while stations 3 and 4 were dominated by body size class A4 (>20–40 mm). The respiration classes B2 (tegument), B3 (spiracles), B4 (aerial/vegetation) and B5 (lung) in station 4 dominated other stations in relative abundance while B1 (gills) dominated station 1. Mobility traits; C1 (climbers) dominated stations 2 and 3 while skater (C5) and burrowers (C6) dominated stations 1 and 4 respectively. Streamlined (D1) body shape was highest in station 1 while D4 (cylindrical) body shape dominated station 4. Conclusion & Significance: This study was able to elucidate the effect of pollution processes going on in River Chanchaga as a cause of differences in the organization pattern in the distribution and composition of some macroinvertebrates in the water course. The downstream stations most especially stations 3 and 4 were seriously affected as a result of the perturbed state occasioned by varied degree of anthropogenicity such as illegal gold mining activities, localization of industries, residential buildings, farm settlements.
