Air temperature, water temperature, pH, total alkalinity, hardness, turbidity, and dissolved oxygen will be measured following the protocols that are provided with the LaMotte Chemical Co. chemical testing kit that is used by Alabama Water Watch and compared to historical data. To help you interpret your results and provide a historical comparison, you should refer to the Alabama Water Watch website at http://www.alabamawaterwatch.org/get-involved/get-certifiedas-a-water-monitor/. Additional information regarding water chemistry is available from the EPA Volunteer Stream Monitoring: A Methods Manual, Ch. 5 Water Quality, which can be found at: https://www.epa.gov/sites/production/files/2015-06/documents/stream.pdf Procedure At your assigned site, make notes describing the site and physical conditions. Record the data on the Alabama Water Watch data reporting form. • Air temperature °C – shade from the direct sun. • Water temperature °C. Place the thermometer into the water and allow it to sit for a few minutes to equilibrate. Take the reading while the bulb of the thermometer is still in the water. • Determine the pH following the instructions in the kit. • Determine hardness following the instructions from the kit. • Determine the total alkalinity following the instructions in the kit. • Determine the turbidity of the water sample following the instructions in the kit. For purposes of interpreting your results, you should consider the units JTU to be equivalent to NTU. • Determine the dissolved oxygen. Two replicate samples need to be collected. Collect samples by gently inverting the sample bottles under the water. Seal the sample bottles under water with the caps, making sure that there are no air bubbles in them. • Perform the titration for each of the replicate samples. If the results are within 0.5 mg/l the results can be used. If not, the bottles need to be rinsed and the sampling procedure for dissolved oxygen needs to be repeated. • Determine percent oxygen saturation using the water temperature and dissolved oxygen values with the nomogram provided. Report Include the usual header information, but there is no species list and you should omit Introduction and Methods. Your Results section should include a table showing each property measured, the value recorded for that property (with units), the historical range (based on historical data for the Conecuh River at the site where we sampled and the site just north of Troy), and the standard range for a river with good (or expected) water quality, and the source of that standard (either AWW or EPA). 1 Do NOT include other data, e.g. calculations, from the datasheet in your table. For the historical data, you will need to use the maps on the AWW website to find Troy and the Conecuh River. In Discussion, you should interpret your results and compare them with the historical and expected values for each property. Speculate as to why you see the differences (or similarities) that you observed? What are the limitations or caveats to your data? You should also include a brief discussion of a published study from a scientific journal that investigated water chemistry in natural surface waters. Incorporate the findings of this study into your narrative and draw comparisons. Your Reference section should include Alabama Water Watch and U.S. EPA, as well as other cited sources of information. Remember to use Council of Science Editors (CSE) Name-Year citation style. If you did not cite something in the text, it should not appear in the References section. 2 General features of lab reports: Labs must be typed; use a standard 12-point font (Times New Roman, Arial, etc.) for the text of the report. Labs must be written in complete sentences, with correct spelling and punctuation. Lab reports are due prior to the beginning of lab class of the specified due date. You will lose one point per day for labs turned in late; no lab report will be accepted more than three days late. An unexcused absence on the day of lab will also result in a deduction of one point (even if the report is turned in on time). Lab reports must be written in your own words. Do not copy from other members of your group, from the internet, or from other sources. Do not copy and paste from the lab handouts into your write-up. Do not use direct quotes; the information must be in your own words. Numbering the pages: Number each of the pages at the bottom. Don’t use a cover page. Terminology and other notes on grammar, calculations etc: Tenses for different sections of the report – The introduction should use past tense when referring to previous studies and future tense when referring to what will be presented in the report. The methods section should be in past tense. The results and discussion sections are generally in past tense, except when referring to information presented further along in the report, areas for future study, etc. Spacing – Double space the text throughout the report. Text in tables and figures, as well as references, may be single spaced. Numbers – A zero must always be put before a decimal point if there is not another number before it, e.g. 0.45 not .45. Do not use more than two decimal places. In the text, numbers less than 10 are written out in letters, e.g., three not 3. However, numbers associated with a unit of measurement are always written as Arabic numerals, e.g., 1 m2, not one m2 . Calculations – When reporting calculated values, show your work! You must retain the computer files of your work for this course until the semester is over and you have received the final grade for the class. Format for General Ecology Lab Reports (unless otherwise specified) Name: Lab Section: 1 Title of Lab: Date of Lab: Location of the lab: Briefly describe the site and location, i.e., the lab was performed in the wooded area of the Troy University Arboretum. Include the latitude and longitude (available from Google Maps) reported in decimal degrees, e.g. 31.784°N, 85.975°W. Physical conditions: Describe the weather during the lab, e.g., sunny and 30 °C. Species studied: Give the common and scientific names of all species observed in the lab. The scientific names of species must be accompanied by the authority (the last name of the person who named the species or an abbreviation). The primary source for plant scientific names and authorities is the Alabama Plant Atlas. Put the information in the following format: Common Name Tuberous Vervain Southern Crabgrass Scientific Name Verbena rigida Digitaria ciliaris Authority Spreng. (Retzius) Koeler The genus is always capitalized, and the species is not. Scientific names should be italicized. The authority is not italicized. Introduction: The introduction defines the general purpose of the lab and introduces specific terminology and concepts related to the lab. Methods: The Methods section describes the step-by-step procedure that was used in the field. Include all equipment that was used in the performance of the lab exercise. Do not write instructions. Typically, you should cite the lab handout as your source of information. Results: This section contains tables and/or figures. You should have an introductory sentence or two that refers to the tables and/or figures. Pictures, maps, graphs, and diagrams are all figures. You need to have “stand alone” titles for figures and tables. For example: Figure 1. Species-area curve for herbaceous plant species collected at Troy Arboretum. Figure 2. Logarithmic plot of species-area relationship for herbaceous plant species collected at Troy Arboretum. Tables and figures should be numbered in increasing Arabic numerals, e.g., 1, 2, 3, 4, in the order that they are first cited in the text. The word table or figure is always capitalized in the text when referring to a specific table or figure, e.g., Table 1, Figure 1. Discussion: This section should summarize the main findings of the experiment. Do not repeat the results in paragraph form. Explain how the findings of your work compare with the expectations of the study. 2 Unless otherwise instructed, your discussion should include an outside reference from a published scientific peer-reviewed journal study that was conducted on the topic and used a similar method for collecting data. The publication date of the study should be within the last 10 years. Print out the first page of the article and attach to the end of the report for verification of your source. References: All references cited should be put into the References section. Wikipedia, blogs, and other similar sources are not acceptable. References are listed in alphabetic order of the first author’s last name. Examples of proper reference listings are shown below: Gotelli, N.J. and L.G. Abele. 1982.
