These insects have adaptations that allow them to effectively navigate an environment that is considerably darker than the one their day-dwelling relatives inhabit. These adaptations may include olfactory, auditory, as well as visual adaptations. Many night-flying insects exhibit strong phototaxis and an ability to detect a broad spectrum of light, including ultraviolet (UV) wavelengths. Several methodologies have been developed to sample for adult flying insects. Light trapping is a simple sampling method that uses a translucent material of a known size and a central light source. This laboratory exercise will utilize the light trapping method to collect data under two different light sources (incandescent and UV). From the data collected, inferences can be made about the composition of the insect community, including differences in UV affinity/detection. Objectives 1. 2. 3. 4. To create hypotheses and test predictions regarding insect vision. To become familiar with common sampling methods for adult invertebrates. To become familiar with identification of common flying invertebrates. To quantify taxonomic and functional diversity between different treatments. Methodology 1. Develop hypothesis and prediction 2. Choose an appropriate location for sampling in your designated area (area with two trees appx. 8ft apart) 3. Tie a rope between both trees about 6ft above the ground. 4. Take a sheet of known size and pin it to the rope. 5. Secure your light source with your designated light on the ground shining up onto the center of the sheet. 6. Turn light source on at designated time and keep it illuminated for 60 minutes. 7. Sheets can be checked and insects removed intermittently with forceps and preserved. 8. After 60-minute period, secure a ground cloth under your sampling sheet and using a squirt bottle, spray 70% ethanol on the sheet and collect insects from the ground cloth . 9. Fill the remainder of the container with 70% ethanol. 10. Sorting, identification, and data analyses will occur in the following lab. Troy University BIO L229 - Guidelines for General Ecology Lab Reports - Fall 2018 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. 1 Format for General Ecology Lab Reports (unless otherwise specified) Name: Lab Section: 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. 2 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. 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. Statistical distributions of West Indian land-bird families. Journal of Biogeography 9: 421-435. • This should be cited as (Gotelli and Abele 1982) in the text. Keener, B. R., A.R. Diamond, L. J.
