question 36

Multiple Choice

You have counted the number of amphibians and reptiles in the same experimental 1 km by 1 km area over the last five years.You also have a control plot of the same size nearby that is part of your sampling each year.Every year you have reviewed your data to understand which species were common or rare,and whether equal numbers of individuals were counted in those categories.What your data show is that in the experimental plot more species become rare to encounter and a large percentage of species that you do encounter tends to be more common from year one to year five.However,this is not the case in the control plot,which shows no change from year one to year five.You now plan to plot these data for a presentation.What will your diversity indices look like?

• A) The graphs will show that species diversity (H) is negatively associated with time in the control plot and positively associated with time in the 1 x 1 km plot.
• B) You cannot graph these data.
• C) The graphs will show that species diversity (H) is not affected by time in the control plot and negatively associated with time in the experimental plot.
• D) Species rank will be on the x axis and species diversity will be on the y axis. The two lines will be parallel.
