Wetland ecosystems are diverse ecosystems with fluctuating water levels, periods of oxygen stress, hydric soils with varied hydrological conditions. They are an important functional part of the landscape (Mitsch and Gosselink, 2000). Among the inhabitants of the wetlands, the macro-invertebrates are in close contact with water and are affected by changing water quality, periods of anoxia, accumulating organic matter (Craft, 2000). Aquatic macro-invertebrates have been found sensitive to changes in their environment and a feature that has been proven useful in the quest to find indicators of environmental conditions. The community characteristics of macro-invertebrates, such as diversity and richness, are often used as indicators of the degree of pollution of water bodies to supplement and deepen the meanings of physico-chemical information (Abel 1989, Arimoro et al. 2007, Barton 1996, Hellawell 1978, Plafkin et al. 1989, Silva et al. 2009, Wright et al. 1984). In order to achieve and maintain the highest water quality in lakes, rivers, and streams, environmental advocates are using the resident organisms living in these waters as sensitive indicators of change. The following are specific research question and objective. Research question
Where would the Macro-Invertebrate diversity and density be high in two different site conditions? Objective
The prime objective of the study was to compare macro-invertebrate diversity and richness in run and pool habitat. METERIAL AND METHOD
Okaloom stream is lactated below Lumitsawa village under Toeb geog. The stream runs through cool...
