Fig. 3. Changes in average egg volume for each clutch throughout the duration of
the study. Data shown are for one H. maculata (Homa1) and two U.
stansburiana (Utst431 and Utst451), all of whom had clutches that
progressed from small follicles to shelled eggs, and two C. collaris
(Crco1 and Crco2), whose follicles increased in volume initially but then
decreased prior to ovulation. Lines are fit solely to illustrate the
trends.
