1.    You want to estimate the density and abundance of leaf litter arthropods in an area of forest at Oregon Ridge. You collect the leaves in six 2 ft2 plots and place them in Berlese funnels. After 5 days, you count the invertebrates that have fallen in to the alcohol at the bottom of the trap. Your data are as follows: 21, 14, 6, 12, 0 and 9 arthropods per sample.

a.    What is the density of arthropods? Present your result in square meters.

b.    In a 27 ha forest, how many arthropods would you expect to find?
