females in the other 2 ecoregions (Table 3A, Fig. 6A). 
Similarly, male red lionfish from the southeast ecore- 
gion also had the highest K and L„ values and achieved a 
greater length at age than males in the other 2 ecoregions 
(Table 3A, Fig. 6B). Data pooled by sex revealed a similar 
pattern, with the highest K and L x values estimated for 
red lionfish from the southeast ecoregion and lowest val¬ 
ues estimated for red lionfish from the central ecoregion 
(Table 3A, Fig. 6C). Separate comparisons were made by 
sex for each ecoregion, with male red lionfish achieving 
higher K and values than females in all 3 ecoregions 
(all comparisons: P<0.05; Table 3B, Fig. 7, A-C). Model
