14 12 10 0 0 200 400 600 800 1000 1200 Cumulative # of Individuals (N) 3. Based on the results of your species-sampling effort curve, what can you determine about the sampling effort necessary to adequately evaluate the species in this community? If we wanted to compare our data to another location, how would we need to sample that location (would we need to sample 12 plots again)? (8pts) ommunity I we wanted se o 0

Explanation / Answer

Instead of plotting cumulative number of species on Y axis you should plot the number of species on Y axis and there is no need to modify the X axis.

This can be done by subtracting the next value by the previous value for example:

First value for number of species = 7 (As shown in graph)

Second value for number of species = cumulative value for second - First value for number of species = 8-7=1

Third value for number of species = cumulative value for third - second value for number of species = 8-8 = 0

And follow this process, to get the entire chart. This would be more usefull to compare if you are going to do sampling at some other location as you can directly compare the number of species found at any area.

If you are going for a new area then there can be spatial variation associated with species hence you have to sample it again. But if you are going to do sampling in this area only then there is no need to go for new sampling.
