es (Table 1). The ratio was larger in males than females. There was no two-way 

 interaction for SEX X AGE (F = 1.08; P = 0.3622), SEASON X AGE (F = 0.97; 

 P = 0.4118) and SEASON X SEX (F = 3.36; P = 0.0709).

* Means are different within grouping (P < 0.05). 



There was no difference between sexes in either parallelism (F = 

 0.00002; P = 0.9964) or coincidence (F = 0.0407; P = 0.9601). There was no dif- 

 ference among ages for either parallelism (F = 0.0105; P = 0.9985) or coinci- 

 dence (F = 0.0277; P = 0.9998), between seasons for parallelism (F = 0.0365; P 

 = 0.8489) or coincidence (F = 0.0407; P = 0.9601), and among years for paral- 

 lelism (F = 0.0173; P = 0.9829) or coincidence (F = 0.0216; P = 0.9957). 



Because there was no difference in parallelism or coincidence regard- 

 less of grouping, all data were analyzed in a single regression equation (Fig. 1). 

 The regression equation, was significantly linear (Mass = 0.02916 * (Girth) - 

 5.5904; r 2 = 0.8044; P = 0.0001) and indicates a strong positive relationship 

 between mass and girth. The lack of difference for either parallelism or coinci- 

 dence indicate that the equation is useful across all age and sex classes regard- 

 less of season or year.
