Figure S1. Autocorrelations of the predator time series.
Figure S2. Autocorrelations of the prey time series.
Figure S3. Cross correlation of predator-prey time series. One curve represents the predator series leading, the other the prey series leading.
Figure S4. Mean species accumulation curves for areas 1 ? 9 from random sub-sampling (100 permutations without replacement) at each sampling interval from the total species pool. Note that the set total for area 1 is 12000.
Figure S5. The geographic distribution of spiny dogfish, Squalus acanthias, red hake Urophycus chis, and silver hake Merluccius bilinearis, based on fishery independent trawl survey data, during 1970 to 1994. Data are averaged within 0.5o x 0.5o bins and colour coded according to scale on the right (units: mean number per tow). The histogram summarizes the catch data across latitude.
