Essay

Refer to the table.
Table 3: Species Abundance in Different Communities
Suppose you are researching an ecological community in a new study area. You divide your study area into quadrats and sample one quadrat a day to determine the species that occupy the area and how many individuals of these species are present. Assume that by the end of your sampling efforts, you have identified all of the species that occur in the study area. Assume that each quadrat sample now reflects a separate community. Focus on samples in quadrats 5, 10, and 12, which will now be referred to as community 5, community 10, and community 12, respectively. Refer to abundances of species A-H shown in Table 3 for each of the three communities and use the data to determine the proportions of species present in different communities to answer the following questions:
a) Quantify the proportion of species present in a new table (this will be referred to as Table 4).
b) Use the data from Table 4 to determine the abundance rank of each species, where a rank of 1 is the most abundant species. Create a new table (this will be referred to as Table 5) showing this data.
c) Based on the proportional abundance and abundance rank of each species use the data in Tables 4 and 5 to graph the proportional abundance of each species as a function of abundance rank for each community. Graph your data as a line graph (this will be referred to as Figure 3).
