However, later analyses of the data and critical review of the original paper revealed different possibilities for those population fluctuations. Some of the more interesting reviews can be viewed here. Read and consider their ideas before you do your workshop.
Still later, other authors provided other possible reasons for the coupled fluctuations, including Keith (1983), who argued that it was not predation, but a shortage of suitable winter forage that caused the hares' population decline. Keith showed that heavily browsed plants produce high levels of alkaloids and other aversive compounds that may make them toxic or highly unpalatable to the hares. While he agreed that the Lynx population depended on the hares, he proposed that it was food supply that affected the populations of both predator and prey--and not predation precipitating decline in the hares.
As add as it may sound, Moran (1949), and later reviewed by Ranta, et al. (1997) suggested that the population fluctuations were correlated with sunspot activity. In any case, Moran's hypothesis was challenged by Ranta (1997), who noted that no other cyclical patterns similar to the hare/lynx pattern were noted elsewhere on earth in relation to sunspot activity, which would be expected if sunspots were truly the cause.
