Treatment effects on population-level stickleback variables.

Results of linear mixed-effects modeling of stickleback population-level response variables as a function of variance treatment and block effects (not shown). Significant or marginally significant effects are indicated in boldface () or italics (). Variables marked with an asterisk (*) or dagger () were log-transformed or exponentiated, respectively, to improve normality. SL = standard length, GRN = gill raker number, GRL = gill raker length, BD = body depth, SC = stomach content. Refer to text for definitions of diet indices.
