Collect aquatic macroinvertebrates from different parts of t
Collect aquatic macroinvertebrates from different parts of the system with the pond nets. Sample the river bottom and just under the banks, and near woody vegetation. Sort the invertebrates in the trays and identify them with the identification keys that will be provided. Use forceps to handle the invertebrates. Use the Alabama Water Watch Bio-Assess sheet to tally the different types of invertebrates and calculate the scores for the two sites surveyed (Conecuh River and the beaver pond). You need to compare and discuss the results of the water quality of the Conecuh River and beaver pond sites as determined by the bioassessment of the aquatic invertebrates. Worksheet for Bioassessment Lab1.Are most of the invertebrate animals used in a bioassessment of a body of water mature adults, or immature nymphs? Find examples of the taxa recorded in the data set by using web sites ending in “.edu” or “.gov” or “.org”. Also, correlate the taxa recorded with the key to macroinvertebrates file.2. List two taxa of Group I macroinvertebrates that are the least tolerant of pollution.3. List two taxa of Group II macroinvertebrates that are intermediate in their tolerance of pollution.4. List two taxa of Group III macroinvertebrates that are the most tolerant of pollution.5. Which abiotic factors addressed in the water chemistry lab likely influenced greater biodiversity and, therefore, a higher overall water quality index value in the Conecuh River vs. the beaver pond? I will provide experimental data later
