Abstract: Testing the biodiversity in aquatic macroinvertebrates organisms at Beaver Lake in Memphis, Tennessee was conducted in the Spring of 2015 at the outer skirts of the lake. The testing sites contained two separate fish species, Lepomis macrochirus and Micropterus salmoides that had their tail fin snipped for identification purposes in the two testing methods of the biodiversity. The first testing method was to collect the snipped fish and dissect their guts and examine it’s contents. The second method was net sampling with a D-net device. The results observed from the two methods showed that the majority of the species observed were from the family Chioronomidae and Order Odonata. The other subsidiary contents observed in the biodiversity during the testing were various organic material, insects and crustaceans. Introduction: This research involves investigating the biodiversity of the microinvertebrates in Beaver Lake in the Spring of 2015. Thus, biodiversity includes genetic variation within species, the variety of species in an area, and habitat s within a landscape. Biological diversity is of fundamental importance to the functioning of all natural and human engineered ecosystems, and by extension to the ecosystem services that nature provides free of charge to human society. Living organisms play central roles in the cycles of major elements like sulfur, nitrogen and phosphate and water in the environment, and diversity specifically is important in that these cycles require numerous interacting species. This research was conducted in the spring because of the class schedule and because of the spring turnover. During the spring turnover the melting of ice occurs, warming of lake waters, density changes, and circulation of total water volumes.
