Trends in marine fishery catches as a function of fish diversity. Duffy, et al, 2008.

Trends in marine fishery catches as a function of fish diversity. (A) Trajectories of fish and invertebrate collapses (i.e., falling below 10% of maximum historical harvest) over the last 50 yr (♦=collapses by year, ▲=cumulative collapses). Data are shown for all (black), species-poor (<500 species, blue) and species-rich (>500 species, red) Large Marine Ecosystems (LMEs). Regression lines are best fit power models corrected for temporal autocorrelation. (B) Map of all 64 LMEs, color-coded by total fish species richness.
