Species Diversity Lab Grade Sheet. diversity index we will use is the Shannon Diversity Index. Count at least 30 cars in the lot. Identify the parking lot that was the most diverse. S p i = n After determining the number of each species (car), in each parking lot, the Shannon Diversity Index will be calculated separately for the student lot and the staff lot. Objective: Understand how to conduct a ecological-based field study. Another human factor which causes a loss in biodiversity is litter. Post Lab Questions 1. -all organisms and nonliving entities that occur and interact in a particular area at the same time. Post lab Questions— Write out and answer the following questions. Write out and answer the following questions. Community 3 contains 10 species, with 18 individuals from 2 of the species and 8 individuals from the remaining 8 species. Our calculations might have not been accurate since we might have not had an accurate number of the species. If you conducted this lab in a shopping mall parking lot, predict whether the diversity index would be high or low, and how it would compare to the school parking lots. Section 1: Prelab Reading, Practice & Questions. Species diversity is the measure of the diversity within an ecological community that incorporates species richness and the evenness of species abundances. I. Framing the Investigation: Background … ii. Identify the parking lot that was the most diverse. 3. Background: A study of biodiversity requires an understanding of several terms and concepts. Based on your observations during the lab, explain why your prediction in question #1 of the prelab was supported or not supported. -a population or group of populations of a particular type of organisms whose members share certain characteristics and can breed freely with one another and produce fertile offspring. Introduction The diversity of species in an ecosystem can be used to determine the health of an ecosystem. Share data with a group that chose a different plot area. Species richness is a measure of the number of different species present in an ecosystem, while species evenness measures the relative abundance of the various populations present in an ecosystem. 2. Each species varied in its abundance because we only observed one spider, one black bug, five green bugs, one unknown plant, fifty ants under a rock, ten hind’s willow, sixty leafs of an unknown plant and other species as shown in our data above. Materials: vehicles parked at the school, calculator, graph paper . As species richness and evenness increase, so diversity increases. 2. Shannon Diversity Index. Back of the Building. August 2017. 1. Developed by E. A. Betts . The Simpson Diversity Index is one of the most commonly used measures of species diversity. 3. 4. Calculate the Simpson Diversity Index for the parking lot. December 2017 It is YOUR responsibility to organize the data into a chart and do all of the calculations on your OWN. In this activity your "ecosystem" will be the school parking lot or a natural area on a field trip, and the "species" will be the different car models and colors for the parking lot or real species for a field trip. The diversity of species present in an ecosystem can be used as one gauge of the health of an ecosystem. In this lab you will calculate the Shannon Diversity Index for cars in a parking lot. In an ecological survey designed to measure species diversity, a wildlife biologist might determine the number of individuals of each species present … Indices of Diversity: Species Richness (R) The species richness is based solely on the number of species found in the given area and does not reflect the relative dominance of species. Indices of Diversity: Species Richness (R) The species richness is based solely on the number of species found in the given area and does not reflect the relative dominance of species. List the single most abundant species in each set of data, and write a plausible explanation to explan why these are the most abundant species. n p N i i = H' S 1 p [ln(p )]ii i= - The student parking lot was the most diverse. IV. Species may be plants, animals, fungi or microbes. Lab: Parking Lot Biodiversity. Developed by E. A. Betts . Index). The lab write up… Title. The lab write up… Title. Section 2: The Lab! Time: 40 minutes . On a weekday morning in August, just one pickup truck sat in the sprawling visitors' parking lot here at this U.S. Department of Agriculture (USDA) facility. Purpose: To develop an understanding of the Shannon-Wiener diversity index and species richness as tools for quantifying biodiversity and assessing human impacts on the environment. Organize your team so that you collect your data as quickly as possible. Calculate the Simpson Diversity Index for the parking lot. If you conducted this lab in a shopping mall parking lot, predict whether the Shannon Diversity Index would be high or low, and how it would compare to the school parking lots. Answer all the conclusion questions. Diversity Index. Simpson's Diversity Index is a measure of diversity. You may do calculations by hand or use a spreadsheet. Select “cars” such by color and make for which you plan to measure species richness and species diversity. After calculating . SPECIES BIODIVERSITY LAB . 3. “Species diversity is perhaps the easiest to understand. All cars in entire parking lot. The Simpson’s index ranges from 0 to 1, where 0 means no diversity and 1 means infinite diversity. 1. In ecology, it is often used to quantify the biodiversity of a habitat. Our prediction was correct, because we predicted that the student parking lot would be move diverse.
