## Figure 2.
Predicted lambda of rock and white-tailed ptarmigan populations in relation to the
frequency of severe years. Models were run with three projection matrices representing rates from 2004–2006.
Solid circles refer to calculations of juvenile survival as a proportion of adult
survival. Open circles refer to juvenile survival assuming a constant rate of 0.27.
Values for all parameters are shown in Table 3.
