In a tropical ecosystem, one of the major fauna are the macroinvertebrates (e.g. arthropods, mollusks and annelids), and one of their highest diversity is concentrated in the freshwater ecosystems (Flores and Zafaralla, 2012; Dodds, 2002; Tumwesigye et al., 2000). Macroinvertebrates are an integral part of aquatic macrobenthic community (Mantel et al., 2004; Bouchard, 2004; Dodds, 2002). They break down materials from primary production thereby assimilating and breaking large particles into smaller pieces making energy and nutrients available to other organisms. They are also key prey items of vertebrates, including fish, birds and humans. Moreover, the biodiversity of macrobenthic invertebrates are effective surrogates of ecosystem attributes, and on which abundance of functional groups indicates anthropogenic impact (Adesalu et al., 2016; Merritt and Cummins, 2006; Yildiz, 2005; Mantel et al., 2004; Bouchard, 2004). They are more useful to monitor pollution compared to algae, which bloom and die more rapidly, and fish, which usually having lower species richness and diversity, and easily escape sporadic pollution events (Morse et al. 2007). In freshwater ecosystems like lakes, macrobenthos diversity is influenced by several factors. Benthic assemblages was affected by predator in New Zealand and Paleartic springs (Barquin and Death, 2006), other important determinants include altitude (Jacobsen, 2008), stability of abiotic parameters and isolation (Shulman and Chase, 2007; Koperski 2010a). However, the definite role of environmental parameters on the entire macrobenthos can be challenging to generalize. Specifically, responses to organic pollution is highly variable. Diversity of macrobenthos was not correlated with nutrient enrichment or habitat degradation (Jonhson and Hering, 2009); but was negatively affected by high concentration of toxicants (Wilson, 2008). Response of macrobenthos to disturbance is also taxon-specific. Ephemeroptera and Hirudinea was affected by organic pollution; Chironomidae by heavy metals; Gastropoda by type of substrate, Odonata by stream width (Kopersky, 2010a; Krodkiewska, 2003; Karimmousavi et al., 2003).
