Part of the problem in doing the math on sampling effort is not having knowledge of the variability among vs. within. It's hard to know how much additional replicates of a species will provide vs. another species.

When I think about sampling efficiency, my mind often goes to thinking about efficiency of effort, and what we might save by going with a shotgun approach.<br /><br />The shotgun approach (where you sample more or less what you come across) has a number of downsides. However, its major advantage is that you don't expend effort in choosing the samples. If it takes a significant time investment to find every last species, perhaps you're better off forgetting about those last few points, and adding more within-species replicates since you might, for example, get 10 more within-species replicates for the effort you'd spend trying to find every one out-of-species replicate.<br /><br />If there's lots of post-harvest effort or cost (such as nutrient analyses), then being very careful about each replicate you choose makes sense. But what if the majority of the effort in expended on the front end?Alexander Shenkinnoreply@blogger.com
