Refer to the table.
Table 9
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. Use the data in Table 9 to answer the following questions:
a) Create a graph (this will be referred to as Figure 4) of species richness and species diversity over the study years.
b) When was species richness lowest, and when was it highest? When was species diversity lowest, and when was it highest?
c) What is the effect of invasive species H on community structure in year 3 compared to year 8?
d) What is the overall impact of invasive species H on the species richness and species diversity of this community?
