Figure WN28.1. Numbers of snowshoe hares (Lepus americanus) and lynx (Lynx canadensis) fluctuate in 10-year cycles. These can be modeled using coupled differential equations similar to the Lotka–Volterra equations presented at the opening of this discussion. The figure shows the number of lynx furs collected per year between 1820 and 1940 from various sites in the Canadian Arctic. (Redrawn from Fig. 1A in Stenseth et al. 1998.)
