To construct the species accumulation curve for this spider collection, choose a specimen within the collection at random. (I recommend marking them in some way so that you know they have been sampled.) This will be your first data point, such that X = 1 and Y = 1, because after examining the first individual you have also identified one new species! Next move consistently in any direction to a new specimen and record whether it is a member of a new species. In this next step, X = 2, but Y may remain as 1 if the next individual is not of a new species or it may change to 2 if the individual represents a new species different from individual 1. Repeat this process until you have proceeded through all 50 specimens and construct the collector’s curve from the data obtained (just plot Y versus X)
