Table 2. Parameters from a mixed model of proportion of eggs
normally fertilized across different sperm concentration in mussels,
fitted using a Bayesian approach. Shown are posterior means and the 95%
highest posterior density (HPD) intervals for (a ) random effects
of measurement block (V block), male identity
(V male), female identity
(V female), specific combinations of males and
females (V male × female), and specific
environment (Ve ; residual variance) and
(b ) fixed effects of population (3 levels; Geelong as the
reference), body condition, gamete age (minutes), sperm concentration
(continuous variable fitted both as a as linear and quadratic term),
density of the male, density of the female, and their interactions with
each other and with sperm concentration.
