Figure 4 . 5 



Plot of natural log Nt vs. natural log Nt+1 

 for the early winter mule deer population, 

 1960-1987, indicating rate and direction of 

 change in population growth in relation to 

 population level. Starting at S and 

 following the points, lines moving above the 

 horizontal indicate increased population 

 (positive growth rate) . Distance of the 

 point above or below the 45 degree line 

 indicates growth rate or decline. Type of 

 line changes with each full population cycle 

 (e.g., from low to high to low).
