Aquatic Invertebrates in Pool and Riffle Habitats of Blackburn Fork Michael Railling Wildlife and Fisheries Science Tennessee Tech

Project summary Problem: Are the aquatic invertebrates the same in pool and riffle habitats. Problem: Are the aquatic invertebrates the same in pool and riffle habitats. Objective: Show that the two habitats should be comparably different by scoring the different taxa. Objective: Show that the two habitats should be comparably different by scoring the different taxa. Expected Results: In the pool more tolerant taxa will be found. The Riffle will support taxa that are more susceptible to poor water quality. Expected Results: In the pool more tolerant taxa will be found. The Riffle will support taxa that are more susceptible to poor water quality.

Introduction/Background Stream macroinvertebrate assemblage varies at both regional and local scales (Heino et al. 2002). My experiment the samples are taken only feet away from each other, however the Taxa Richness and Percent EPT’s should be different. Stream macroinvertebrate assemblage varies at both regional and local scales (Heino et al. 2002). My experiment the samples are taken only feet away from each other, however the Taxa Richness and Percent EPT’s should be different. Lower water quality is directly associated to diversity (Heino et al. 2002). The water quality of pool areas is lower than that of Riffles; causing less diversity.

Objective/Hypothesis Statement Hypothesis: Hypothesis: What different proportions of Genera can be found in pool and riffle habitats of the Blackburn Fork, and can the differences of genera be linked to different water quality within theses habitatats. Objective: Objective: To show that different genera are found in different habitats. Using Taxa Richness and Percent EPT’s

Methods Using 6 Hester-Dendy samplers Qualitatively, 3 in pools and 3 in riffles. Using 6 Hester-Dendy samplers Qualitatively, 3 in pools and 3 in riffles. Scrubbing the bugs off the substrate Scrubbing the bugs off the substrate Identifying the invertebrates down to genus. Identifying the invertebrates down to genus. Scoring the results using data forms to show the Taxa Richness and Percent EPT’s (State of Tennessee 2002).

Expected Results and Benefits Expected Results: In the pool more tolerant taxa will be found. The Riffle will support taxa that are more susceptible to poor water quality such as EPT’s. Expected Results: In the pool more tolerant taxa will be found. The Riffle will support taxa that are more susceptible to poor water quality such as EPT’s. Benefits: Showing that invertebrates are habitat specific. Benefits: Showing that invertebrates are habitat specific.
