Choy, Christophe PiscartRectangular box nodes represent the 72-hr LC50 data for each group of species (in each box there will be at least one individual species measurements). Round nodes represent random variables: the subscript μ values denote the mean log10 72-hr LC50 for each group; σ^{2} is a measure of within-group interspecies variance; µ_{hyper} and τ^{2}_{hyper} are the mean and variance of the hyper-population of group means. Directed arrows represent conditional probability statements. Prior distributions are placed over σ^{2}, µ_{hyper} and τ^{2}_{hyper}.
