Size and age at sex change.

<p>Frequency distributions of age (a, b) and standard length (c, d) at sex-change to males (determined from check marks) compared to the distributions of male <i>Halichoeres miniatus</i> at collection from (a, c) Orpheus Island and (b, d) Lizard Island. Age and size distributions of males at collection shown in grey, while age and back-calculated size distributions at sex change (from the otolith check marks) are displayed in white.</p

Comparison of sex-related size and age distributions.

<p>Size (a, c) and age (b, d) distributions for two populations of <i>Halichoeres miniatus</i> at Orpheus Island (a, b) and Lizard Island (c, d). Females are shown as white bars and males as grey.</p

Growth of males and females by location.

<p>Comparison of mean daily increment widths of male (i.e. females that changed sex to males; black) and female (i.e. non-sex changing fish; grey) <i>Halichoeres miniatus</i> collected from (a) Orpheus Island (n = 18 males, 48 females) (b) and Lizard Island (n = 16 males, 23 females). Mean standard errors are inset.</p

Comparison of males and female encounter rates between locations.

<p>Frequency of encounters per minute (± SE) for <i>Halichoeres miniatus</i> at Orpheus Island (grey) and Lizard Island (white) sampling locations. Based on the 15 min observations of 7 males and 7 females at each location.</p
