The influence of heavy metals and water parameters on the composition and abundance of water bugs (insecta: hemiptera) in the Kerian River Basin, Perak, Malaysia
The hemipteran (Insecta) diversity in the upper part of the Kerian River Basin was low with only 8 families and 16 genera recorded at 4 study sites from 3 rivers. Water bug composition varied among sampling sites (Kruskal-Wallis χ² = 0.00, p<0.05) but was not affected by wet-dry seasons (Z = 0.00...
