. Average number of macrofaunal species collected per sampling 
effort using various sampling devices (5- and 10-centimeter 
cores and a box). The numbers next to the X-axis represent 
the number of cores treated as one sample; the number just 
below is the interior diameter of the coring device; and the 
bottom number is the total surface area sampled. All cores 
were taken to a depth of 15 centimeters.
