Abstract

Across the boreal forest of Canada, lynx populations undergo regular density cycles. Analysis of 21 time series from 1821 onward demonstrated structural similarity in these cycles within large regions of Canada. The observed population dynamics are consistent with a regional structure caused by climatic features, resulting in a grouping of lynx population dynamics into three types (corresponding to three climatic-based geographic regions): Pacific-maritime, Continental, and Atlantic-maritime. A possible link with the North Atlantic Oscillation is suggested.

3. See P. A. P. Moran [ Aust. J. Zool. 1 163 (1953)] who fitted a linear autoregressive model of order two which exhibits quasi-periodicity but was well aware of its inadequacy. In particular he pointed out the inhomogeneity of the fitted residuals which violated the assumption of a common and constant variance for the white noise term in the fitted model. As an interesting historical point it should be noted that Moran learned about the lynx data when he visited Charles Elton and Dennis Chitty in the Bureau of Animal Population at Oxford after World War II.
