Population Size

We conclude this chapter with a short introduction to a complicated topic, and one that comes the closest to pure mathematics yet - we are going to show that a solution to a question exists, but we are not going to actually find the solution. By way of motivation, we begin with the empirical phenomenon. In Figure 2.21a, I show the spatial distribution of the variegated leafhopper (VLH, Erythronewra varzabz' zs) which is a pest of grapes in California (Settle and Wilson 1990), during an invasion...
